|NetMonitor in Nokia DCT1-DCT3 phones (part 1/7) (2002)|
I'd like to write, that I'm not professionally connected with any cellular network or phone company. This NetMonitor guide is based on many different materials and exists thanks to the support of many different people (see Information sources). This is a guide made by user. It may lack description to some functions or contain errors and mistakes (resulting from wrong translation or my ignorance) and some strange expressions. Many questions remain unanswered. Furthermore, this page is still "under construction". Encouraging, isn't it? But that's the (sad) true: Nokia doesn't make appropriate materials available... I can only assure you, that I do my best to make this NetMonitor description as reliable and complete as possible.
In this moment on my homepage you can also find Polish version of this FAQ. English language version was created with help of Michal Jerz - author of excellent page My Communicator: http://my-communicator.com.
I'll be very thankful for any help in creating and maintaining this guide - please send me any information (or URLs where I can find it), suggestions and remarks. My FAQ currently concerns Nokia 2110i, 2120, 2140, 2160, 3110, 3210, 3310, 5110, 5130, 5160, 5190, 6110, 6130, 6150, 6160, 6185/6188, 6210, 6250, 7110, 8210, 8810, 9110 and 9210 series of phones. If you have NetMonitor enabled in any other model (for example in 2110i, 6090, 8xxx, 9000), please contact me (to let me know about the differences and possible new tests).
Herewith I inform, that I don't bear any responsibility for any damages and other consequences caused by applying following information (you use it on your own responsibility) !
Net Monitor is just a special mode, which - when activated - shows different information about the network and about phone modules, SIM card, etc. After activation your phone will usually display a new, additional menu containing strange and constantly changing letters and digits. There are no standards here - each phone shows different data and there are different methods of activation (my description concerns NetMonitor mode in Nokia phones - if you have some other phone, you have to go somewhere else). I can even say, that NetMonitor (in some form) can be found in practically each present mobile phone (because it is unprofitable for the producers to make two separate software versions - with and without NetMonitor). Here you can find some URLs to the pages describing activation and/or individual NetMonitor menus in other phones:
"Normal" users surely don't need any NetMonitor, because simply most of the data included there can be of any interest and use only for specialists (who can find out almost everything about the network). You also can:
If you still think, that you don't need it, read other pages concerning Nokia phones.
I'd say: NO. Each phone monitors the network even when there is no NetMonitor menu active.
But why some users say, that they have to charge their batteries more often after enabling NetMonitor? It is easy to explain: they frequently switch from one test to another (some people cannot stop ;-) and do it habitually) and the phone after each key press (by default) turns on the light (and uses much power - see test 23). This can be partially cured by using test 18. Additionally, some tests (for example test 17 or test 19) can put your phone in a state of constant network searching (which drains the battery).
To recap, NetMonitor activation itself doesn't affect power consumption. It can be only changed by some conscious user operations...
Older phones (for example, 1610, 2110, 3110, 8110i, 8810 and 9000 series) don't have to have this option. When it's available: I don't know exactly which programs to use (I heard only, that probably version 0.6 of PC-Locals allows to make it in older models) or how to modify EEPROM memory (if you know anything about that, please contact me). In this moment I can send you to:
Phones from DCT3 generation (3210, 33xx, 3410, 51xx, 61xx, 62xx, 7110, 82xx, 9110, 9210, etc.) You can do it in two ways:
You can also:
I also heard, that in some copies of Nokia 6110 and 5110 phones it is possible to activate NetMonitor by a key combination (by pressing Menu key and typing 10 - this should work even when NetMonitor menu is not visible).
In analog phones using special menu, which allow to programm NAM code (in some models only - like Nokia 2160, 2120, 5160, 6160, 6185 and 6188):
or entering Menu 3 3 (according to http://www.ras.ru/~sashka/nokia/550/ in Nokia 550) and setting it to "ext. test". Later you should restart phone (?)
Phones from DCT4 generation (3510, 6310, 6310i, 6510, 8310,etc.) seems to have netmonitor in each firmare version (for example, in 6310i, when you try to enter Menu 15, you could see "Shortcut not available", not "Incorrect shortcut"). In this moment it isn't known, how to activate it - Nokia hides it and sell phones with this option separately. It was activated in prototypes of these models given to some magazines to make user tests.
I'd like to draw your attention to one detail - in Nokia phones you just activate the monitor and not upload it (it is always in your phone - described methods just reveal it as an additional menu).
Each program described in previous point allows you to activate one of two NetMonitor versions:
The method of re-programming EEPROM memory is connected with opening the casing and making modifications in your phone (which leaves many traces, scratches etc. and voids warranty).
However, these problems don't appear (you don't have to be affraid) when using one of the described programs or code (but I can be wrong . there are opinions that this method leaves a trace in phone.s memory, too)...
Of course, before getting phone to service, is better to deactivate NetMonitor. Sometimes, for example, when phone's energy system is damaged, it could be impossible - you can have some problems then (some of people working in service can think, that you broke warranty - it depends on concrete people)..
YES - It's normal. We have such situation in Nokia 3210. "Lost" Menu 10 is reserved for SIM application toolkit and you will see it, when you will have access to them (when your SIM card will have this feature built in - you CAN'T activate it different way).
When you enter this menu, you can type number of the test, which should be displayed (1 to 19 in limited version, higher numbers in full version - Caution! Entering number 241 removes NetMonitor menu and 242 switches it to the limited version - you'll have to use one of the methods described in How to activate it ? to regain access to the full version !). Before number of test you can add "+". Unfortunately, in Nokia 6210/7110 there is one wrong thing here: before entering number of new test you must delete old number using right function key (in other models you can enter it without it).
After pressing OK the chosen test appears on screen (and its number is shown on the top) in place of your network name/operator logo (BTW: in some phones (like Nokia 3310), when you will enable clock, alarm clock, stopwatch, countdown timer, second line (ALS function), test in netmonitor and lock keypad, time will disappear :-)). If you enter incorrect test number, NO TEST appears on screen and the phone returns to the last correctly displayed test. If entered number is greater than 256, 512 or 768, then 256 (or its multiple) is subtracted and resulting menu number is displayed (for example numbers 300 and 556 run test 44). Some test when accessed this way (by typing its number and pressing OK to enter them directly) modify its contents (details are described later, I call this "DIRECT" menu access' - for example, see test 18).
You can look at different tests by scrolling them using up/down arrows (don't worry - this method doesn't change any settings in tests) - each key press moves you to the next/previous available test. In some models (for example in 5110) these keys have different functions (like displaying last dialed numbers, opening and scrolling phonebook or changing the volume) - unfortunately they don't work while NetMonitor is on screen:-(. However, you can still adjust volume during a call in Nokia 5xxx/3210/3310/6188/6185/6160/6120 - by pressing and holding (longer than normally - about a second) one of the arrow keys. Interesting fact from 5120 - when enter "+" as test number, previous used test will be displayed and Up/Down keys will function normally.
Help (description) to the current test can be displayed by pressing and holding * key (repeat this to return to test values). However, this shortcut works only in some phones (my explanation to this fact can be found in Description of the individual tests). That's why I've added these help screens using a bold font in most of the tests... If they are currently displayed, entering menu directly doesn't change its settings.
With any test on screen (in phones other than Nokia 3110), your phone doesn't display some of the messages (for example. "...calling") and there is no calling party identification recognition (the only exception to the rule is a message: 'Note: you have active diverts'). When you type a phone number the test screen disappears (it will come back after you get connected or when you cancel this number from your display).
Remember: your phone is like computer. If you won't disable it and enable (only then it saves all values in EEPROM), it can lost values from tests (for example, info about number of sent/received SMS from test 64, when you will use tips above...
There is one firmware bug connected with using helps (descriptions) to the tests (in this moment, it's confirmed for Nokia 5110, 3210, 3310). If you want to see it:
You can restart your Nokia 5110, if it has older firmware (it doesn't work with 5.24, but with 5.07 and 5.11 works):
TDMA 800/TDMA 1900 phones:
After activation you gain access to the new position (called "Field Test") in main phone menu.
When you enter this menu, you can type number of the test, which should be displayed (1-7 in Nokia 6160) or enter 0 to disable it.
You can look at different tests by scrolling them using up/down arrows. During voice calls, depending on how NetMonitor was entered, the arrow keys may switch tests (you can't change volume then) or adjust volume.
If the keypad is locked while a NetMonitor tests are active, pressing 0-9, *, or # will toggle the screen back to the User Interface Display. Pressing Talk, End, the arrow keys, or the soft menu keys will return the test.
In Nokia 2120 or 2160 you can also display description (help) to displayed tests by pressing and holding "ABC" key.
I've never heard of such accident (my own strange and hard attempts :-) failed, too) during using it in different phones. But of course you should be careful - netmonitor is "unofficial" part of phone's firmware.
