14. Troubleshooting
Note: You will find the Nokia HelpLine contact
card in the Contacts directory. The Help-
Line answers questions and offers instruc-
tions over the phone.
1. Phone interface or communicator interface
does not start (both displays remain blank)
Make sure the battery is properly installed
and charged.
Make sure that the contacts on the battery
and the charging stand are clean.
Battery charge may be too low for operation.
Check the display and listen for the low bat-
tery warning tones. Charge the battery with
the adapter and charger as described in chap-
ter 2 "Getting started: Battery" on page 2-4.
If the NOT CHARGING message is displayed,
the charging is suspended. In that case check
that the temperature of the battery is not
above +45° C (+113° F). Wait for a while, dis-
connect the charger, connect it again and re-
try. If charging still fails, contact your local
Nokia dealer.
2. Power comes on, but the phone interface
does not work
Remove the battery and replace it again (re-
boot).
Try charging the communicator. If you see the
battery charging indicator on the phone in-
terface but the phone does not work, contact
your local Nokia dealer.
Check the field strength indicator, you might
be out of the cellular service area. See the an-
swer to problem number 6.
Check if there is an error message on the dis-
play after switching on. If so, contact your lo-
cal dealer.
Check that the SIM card is correctly installed,
see chapter 2 "Getting started: SIM card" on
page 2-2.
3. Communicator does not activate or appli-
cations stop responding
Close the cover and open it again. If this does
not help, close the cover and remove the bat-
tery. Replace the battery and open the cover
again. Wait while the communicator performs
a self-test and starts. See also problem 4.
4. Resetting the communicator
Sometimes, for example, removing the bat-
tery in mid-sending may cause errors in the
communicator’s file system. If you receive in-
ternal memory or system error messages and/
or reboot prompts, or the device does not re-
spond to commands normally, the reset oper-
ations help you to recover from most of these
problems. Try the reset operations in the order
they have been listed: if checking the file sys-
tem does not help, try deleting temporary
files, and so on. To reset the communicator:
1 Close the cover.
2 Remove the battery.
3 Place the connector end of the battery (the end
with the four metal strips) in the battery cavi-
ty, but do not press the other end in place yet.
4 Place the communicator on a flat surface
with the phone interface display upwards (do
not let the battery slip from its place).
5 Open the cover.
6 Press and hold down the required key combi-
nation and simultaneously push the battery
end of the communicator down, so that the
battery clicks in place. Hold down the keys
until you see progress messages or a confir-
mation prompt on the display.
