Menu 10-90

In Nokia 9110 this test looks like follows:

`Cover aaaa CarKit bbbb Heads cccc`
`CoverCnt CarKitCnt HeadsetCnt`

- aaaa - how many times Communicator's cover was opened
- bbbb - how many times carkit was connected
- cccc - how many times headset was used

Because Nokia 9110 seems to be 100% hardware compatible with 6110, method of simulating headset and car kit should be the same (see Menu 10-75). First of them you can simulate using Menu 10-92 too (when you use it, value of the counter from this test doesn't change !). I recommend to read page http://n9k.ats.pl/tipsframes_eng.html, where you will find more informations about it (for example, another ways to simulate them)...

here's for Nokia 5190:

`M:DCS:DO4100 D:HPA:NTM:NC D:REA:OFS:RU 0000000:000`
`MODESERVSIM DCS AMPSMOD DPWRAPWRSMC PRILIST`

and in Nokia 7110 looks like follows:

`PS0 aaaa EC0 bbbbbbbb PS1 cccc EC1 dddddddd`
`PS0 FFFE EC0 00000003 PS1 FFF8 EC1 00000002`
`Page0 Status EraseCounter Page1 Status EraseCounter`

- aaaa - the same to the parameter bbbb from Menu 10-92
- bbbbbbbb - the same to the parameter dddddddd from Menu 10-92
- cccc - the same to the parameter bbbb from Menu 10-93
- dddddddd - the same to the parameter dddddddd from Menu 10-93

Menu 10-91

In Nokia 9110:

`RESET MISC COUNTERS`
`Use menu to reset misc counters`

By direct enter to this test you can reset counters from Menu 10-90.

In Nokia 7110 this test is different:

`FL 005FC998 E2 0 0 PR 30 1 OM 0 0000`
`NextEntry Addr Length Small Long ErCnt ErMask`

Menu 10-92

In Nokia 9110 it looks different:

`Headset xxx`
`Use menu to toggle headset ON/OFF`

By direct enter to this test you can enable "headset" profile normally accesible after connecting headset (of course, you don't have to have it ;-)) - xxx can have ON or OFF values. When you will use it, value of counter from Menu 10-90 don't change. I recommend to read page http://n9k.ats.pl/tipsframes_eng.html, where you will find more informations about it (for example, another ways to simulate them)...

| Use this test, when you need 'Automatic Answer' function, which allow to receive incoming call without pressing phone's key. This function is normally enable in never Nokia phones with connected set only (in older phones - like Nokia 2110i - it's always visible)

and in Nokia 7110 it looks like follows:

`EP aaaa bbbb #0 cccc dddddddd eeeeeeeeeeee`
`EP F0F0 FFFE #0 0000 00000003 FFFFFFFFFFFF`
`EMark PgStat PgType EraseCount PpInd PpECnt`

- bbbb - the same to the parameter aaaa from Menu 10-90
- dddddddd - the same to the parameter bbbbbbbb from Menu 10-90

Menu 10-93

`EP aaaa bbbb #1 cccc dddddddd eeeeeeeeeeee`
`EP F0F0 FFF8 #1 0001 00000002 000000000002`
`EMark PgStat PgType EraseCount PpInd PpECnt`

- bbbb - the same to the parameter cccc from Menu 10-90
- dddddddd - the same to the parameter dddddddd from Menu 10-90

Menu 10-94

Test in Nokia 3210:

`Vo: aaa bbb Pins: c Mode: dddd State: eeee`
`V: Req ADC Pin Status Mode Band Ch`

- dddd - one of values is AUTO
- eeee - example values are GS05, GS09

and 7110:

`IN E111 F000 ST 0000 0000 0000`
`InExc InRec EmuErr EnvErr RecEr`

Menu 10-95

`1:aaa 4:ddd 2:bbb 5:eee 3:ccc 6:fff`
`6 lowest values at shut down`

Menu 10-96

In Nokia 3210:

`VCX0ADC: aaa TEMP(C): bb TEMP(K): ccc`
`ADC VALUE RF TEMP(C) RF TEMP(K)`

- ccc - temperature of bb counter (in Kelvin degrees: K = C + 273)

and 7110:

`Co: 49 A: 279 Tu: 49 K: 305 Of: 0 C:+32 V5: 2`
`Contrast ADC Tuned Kelvin Offset C`

Menu 10-98

`WR 00000000 0 0000 ER 00000000 0000`
`WrErrCnt WrRtry WrSta ErErrCnt ErSta`

Menu 10-99

`Ead:aaaa Mod:bb MODE: cccc`
`EAD value Acc. status FBUS mode`

- bb - type of connected sound accesories (example values: HP in normal state, HD with headset - for example, HDC-9P). In other phones this information is displayed in Menu 10-75
- cccc - "FBUS" in connection made during FBUS or MBUS cable from older Nokia phone (5xxx, 6xxx) or during Irda connection

Menu 10-100

Test from Nokia 9110:

`a b c ddd e`

`MemUseT %Use MemRelT %Rel MemUnuT %Unu`

Information about using phone's memory. I'm not sure exactly, what memory (when position to phonebook is added, information displayed here is probably about phonebook memory).

Menu 10-101

Menu 10-130

`aaa bbbbbb`
`Slide Open`

- bbbbbb - how many times phone's sliding cover was opened

Menu 10-240
It doesn't show any values, but:

- clears counter reset normally by direct enter to Menu 10-40, Menu 10-60 and Menu 10-80
- enables counters from Menu 10-82 (you can make it by direct enter to Menu 10-81 too).

Menu 10-241
Disables netmonitor (it means, deactivates its' menu) ! To again activate it you will have to use methods described in How to activate it ? Probably after using it you will have to disable and enable phone (to make arrows up/down usable). It's possible too, that these arrows will work only, when you will deactivate netmonitor from computer...

Menu 10-242
Enables limited netmonitor (tests from 1 to 19 only). To enable full netmonitor version you will have to use methods described in How to activate it ? question (phone doesn't allow to use it from its' menu test 243, which normally enable full netmonitor version - you will be able to enter it in program enabling netmonitor in computer only).

Menu 10-243
Enables full netmonitor.

Menu 10-250
Some English descriptions write, that this test cleans information from Menu 10-57 (I didn't notice it).

Menu 10-497
It should deactivate netmonitor like Menu 10-241 (497-256=241). But some sites (for example, www.versamart.com/Nokia5110/nokia5110code.shtml) show, that it could make more:

The tips needs Net Monitor enabled.
Be aware that the trick wil remove Netmonitor in some
sw versions like v4.73 and v5.04.

1. Laungh the NetMonitor in your Nokia 51xx / 61xx
2. Execute the test number 497
3. Free calling for about 90 sec should now have been activated.

The trick has not been comfirmed working yet.

For me, it's rather joke...

13. You can also use a program...

There are programs, which allow to track some of these parameters on computer's screen (of course, phone must be connected to computer):

- program created by Andreas Schmidt (www.aschmidt.de/): shows values displayed by phone in given test and allows to track BTSes (for example, compare their signal level)
- gnokii: it's the name of project (official page - http://multivac.fatburen.org/gnokii/) and software (nevest versions - ftp://ftp.inet.cz/pub/People/Pavel.Janik/gnokii/), which want to be Nokia Cellular Data Suite for Unix and Linux. In this moment it displays information similiar to these displayed by program described earlier.
- Logo Manager (http://clicksave.eu.org/nlm/) it shows view of netmonitor tests.
- created by N. Hüttisch (www.nobbi.com/). It can work with differenet phones (for example, Siemens C10). When you want to use it with Nokia, Nokia Cellular Data Suite is required (program communicates using AT commands). When you will unpack it, in file monitor.ini (it's in archive with program) change comport parameter (you will give there name of port, where 'Nokia GSM Data' and 'Nokia GSM Voice' modems are installed). And that's all...
- Logo Express (http://memsu1.iam.ntu.edu.tw/~jrywu/ or http://logoexpress.bizland.com/): shows LAC and CID.
- from http://members.tripod.com/smssend/gsm_csq.htm (versions for PSION, DOS and Windows): display chart of signal level (besed on signal from phone), work probably with Nokia 6xxx phones only.
- WinTesla: this commercional service program displays many detailed information (for details search some description on pages somewhere in Internet)
- version 1.3 of PC-Locals: there two ways to make it:

  1. in the window, where netmonitor is normally activated, enter number of test - computer will display everything, what could be displayed by phone in this test.
  2. enabling internal program's netmonitor:

     1. select menu 8 (Event Trace)
     2. select menu 9 (Load TRC file)
     3. write name of TRC file (with PC-Locals 1.3 in Internet you can find nse3_433.trc file for Nokia 6110 firmware 4.33) correct for phone's model and firmware (or press Enter and select adequate file). When version from file and phone's version is not the same, computer will confirm, that you really want to load it (it won't damage phone, but parameters displayed by program will be different than adequate parameters from netmonitor in phone).
     4. select menu 1 (MCU Events)
     5. change status of events, which will be tracked in Trace window - you can make it using gray + on the right side of keyboard (you can disable tracking, enable normal or extended tracking). If you want to enable netmonitor displayed after pressing F8 key, you have to enable tracking event CONSTANT_WINDOW_TRA (change to NORM or EXT).
     6. select menu 2 (Event Control) and change to On.

  In "Trace" window you will see now tracked events. Network parameters can be observed after pressing F8. Menu 6 (Break Trace Functions) breakes tracking events.

14. Can I use NetMonitor without SIM card inserted, without PIN number entered or when SIM card is not active ?

GSM standards say, that cellular phone always should allow to make emergency calls (usually 112) - even, when it's was blocked by GSM operator (it means, when normally you can't use this phone - with this IMEI - in network) or when it's without SIM card (eventually it was blocked too). It makes, that after enabling your Nokia looks for available cellular networks. There are some programs in this moment (see in You can also use a program...), which display on computer's screen everything, what could be displayed by phone in this test. Or I will write it different: when you will connect your Nokia to computer and use (for example) Pc-Locals 1.3 or program written by Andreas Schmidt, you can see some information given normally in "Net Monitor" menu. In some phones (I checked it with Nokia 5110) you can have access to this menu (generally, to phone's menu) using gnokii: you should send dtmf sequence to phone (for example, run gnokii with parameter "--senddtmf sequence", where sequence consists of some digits).

When you will enter PIN code, you will be "normally" able to use "Net monitor" menu from phone's keyboard (of course, if it was activated) and all settings and tests inside (for example, not till then in Menu 10-6 you will see "preffered" and "forbidden" networks). You can still display tests using described above programs (it can be usefull, when you want to monitor network state and when you don't want to loose caller identification or when you want to check kind of channel after entering PIN code) - they work independent of it, if you have "Net monitor" menu activated and which test is displayed in phone...

SIM card data can be readed in Menu 10-51 (of course, if your phone supports this test) using these programs independent of it, if you entered PIN code or not. When you don't have SIM card in phone, you will see there "ERROR1".

When you use deactived SIM card, you have access to tests in netmonitor (of course, when its' menu was activated earlier). Network of SIM card is normally monitored. Phone tries to communicate with it only once after enabling phone (netmonitor shows, that CCCH, AGCH, SDCC (phone refreshes TA then), BCCH and CCCH channels are used then - like in normal SIM card). Later it's impossible. It's made againg after reseting phone. Of course, you don't have name of monitored network on screen or cellinfo. Interesting thing is, that, for example, you can normally use BTS test...

15. How can I disable NetMonitor ?

GSM/DCS/PCS phones:

Enter 241 test in phone or use one of described in question How to activate it ? programs (you enter number 241 there, select "OFF" or something similiar...).

TDMA 800/TDMA 1900 phones:

Enter NAM programming menu (*3001#12345# code - some sources write, that you have to write security code instead of 12345), set "Field Test display" to "Off" and reboot phone.

Na pocz±tek

16. Do I need to disable NetMonitor before sending my phone to the service ?

Normally Nokia phones don't have activated netmonitor. When you will give your handy to service, somebody there can think, that you made some strange things with it (of course, it isn't any maxim - it depends on concrete service and people, who will repair your phone)... But I think, that it will be better to save eventually problems connected with it and deactivate netmonitor's menu before giving phone to service (I repeat: it isn't sometimes required, but it's better to make it, when you don't want to have problems)...

Back to the top

17. Is it possible to re-activate NetMonitor after disabling it ?

YES ! You can activate (and deactivate) netmonitor's menu repeat infinitely (and once more ;-))

Back to the top

18. Is NetMonitor available in analog Nokia phones ?

Yes, it seems, that is available in majority of Nokia phones (working in different cellular systems).

Back to the top

19. Does NetMonitor allow to use phone like broadcast station ?

No - if you want to speak without costs with people, which are near to you, you have to use broadcasting station or walkie-takie.

Back to the top

20. I don't have all described tests in my phone. Why ? Can I increase their number ?

This FAQ describes tests from DIFFERENT Nokia phones (models). If you want to increase number of available tests, you can only change your phone to new, which has more tests (like Nokia 7110) or change it's firmware to never - sometimes (like in Nokia 5110) you can have ONE :-) new test (firmware 5.04 and never has additionaly test 89).

If you have ONLY 19 first tests, you have activated ONLY standard netmonitor - enable full (here is more details).

Back to the top

21. Does NetMonitor allow to identify place, where is my interlocutor ?

NO. This information are in networks registry, but they're not sent to your phone. NetMonitor allows however (at least theoretically) to look into parameters of sound, which is sent from his(her) phone...

Back to the top

22. Does NetMonitor allow to identify place, where am I ?

It's possible, but not too precisely. Why ?

Phone can read such parameters required to identify (location of) BTSes like their numbers (see Menu 10-11) or TA (see Menu 10-1), but readed TA couldn't have been distance from BTS station in straight line (signal can break down) and continuosly isn't possible finding, in what direction (what corner) BTS stations are located (which are "seen" by your phone). So, it's possible to identify area only, where you're (in cities, where BTSes are located more close, it will be more precisely). And it can be done by you or your operator...

Back to the top

23. What are NetMonitor codes ?

Sometimes I read advertisements with requests about NetMonitor codes and I don't know exactly, what is it... It simple: in Poland (my country) rather only GSM/DCS phones are used and you don't have rather some special "secret" codes, which activate NetMonitor... When you need it's description - it's in this FAQ.

Back to the top

24. Is it the truth, that in phones with additional hardware changing frequency band NetMonitor doesn't work correct ?

I didn't heard about such hardware. Article about it in Polish Twoja Komorka number 4/2000 (page 18) was only joke...

Back to the top

25. Where can I find description of FBUS/MBUS protocol and commands connected with NetMonitor ?

There are not official information about it. All pages below were created by different people, which observed work of compiled software:

- page of gnokii project. You can find free software published with full source (it's very good to read it to understand protocol) there (on the ftp://ftp.inet.cz/pub/People/Pavel.Janik/gnokii/ you will find the nevest test versions), which work with more and more Nokia phones (Nokia Mobile Phones changed protocols 3 or more times). On discussion list of this project you can find some addresses with pages with list protocol commands:

  - www.gadgets.co.uk/nokia21xx/index.html (Nokia 2110)
  - http://priv5.onet.pl/wa/junk/mbus/ (Nokia 2110 and old phones)
  - www.tec.puv.fi/~s98114/GSM/FBUS.html (NHx models)
  - http://lsc.kva.hu/dl/README.MSGTYPES.txt (NSx models)
  - www.venia.net/tdma/ (TDMA phones)

- you can look on http://atrey.karlin.mff.cuni.cz/~short/sw/ for source to the program for sending logos for Nokia 9110 too
- some information about it are on the page www.gadgets.demon.co.uk/nokia61xx/ too

On the pages above you will find information about commands connected with NetMonitor for NSx models (if you don't know model of you phone, read this page). Always you can use ready and free ActiveX control (http://www.gertjaap.com) working with these models too...

26. Information sources

To make this FAQ I used:

- netmonitor's descriptions from Internet (for example, from "The Nokia page", N. Hüttisch page (www.nobbi.com/) and from www.arcx.com/sites/Nokia6188.htm, http://www.windows.to/wireless/nokia.htm, http://www3.l0pht.com/~oblivion/blkcrwl/cell/nokia/ i www.geckobeach.com/cellular/)
- information from Polish GSM FAQ "PeSTKa" (http://193.193.73.3/gsm/) and Polish site www.fkn.pl (there is, for example, page created by Andrzej Gorny (www.fkn.pl/agorny/) - first description of netmonitor in Polish language - I used parts about handovers and channel types from it)
- knowledge and help from people from Polish discussion groups pl.misc.telefonia.gsm and fkn-l (www.fkn.pl/fkn-l/index.html)
- help from many people (I will write here about some of them: Maciek Oksienciuk (http://angel.qdnet.pl), Jerzy Wozniakiewicz (http://student.wsp.krakow.pl/~jwozni), Juliusz Orlikowski, Slawomir Niemkiewicz, Andzej Bobek, Wojtek, Piotr Glowka (www.gsm.alpha.pl), Michal Jerz (http://n9k.ats.pl), Andrzej Wilczynski, Krzysztof, Marcin Dembinski, Pawel Zerdzicki (http://republika.pl/vosper/, Tomasz Rolewski, Dawid Lorenz (http://shit.prawda.pl)... They helped me with collecting all these information...

People, which are not on this list, should write to me :-) !
