14-2 Establishing communication
4. Resetting the communicator
Removing the battery in mid-transmission
may cause errors in the communicator’s file
system. If you receive internal memory or sys-
tem error messages and/or reboot prompts, or
the device does not respond to commands
normally, the reset operations will help you to
recover from most of these problems. Try the
reset operations in the order they are listed: if
checking the file system does not help, try de-
leting temporary files, and so on.
To reset the communicator, follow these steps:
• Close the cover.
‚ Remove the battery.
ƒ Place the connector end of the battery (the
end with the four metal strips) in the battery
cavity, but do not press the other end in place
yet. You will be balancing the battery at the
edge of its insertion point.
„ Place the communicator on a flat surface
with the phone interface display upwards (do
not let the battery slip from its place).
… Open the cover.
† Press and hold down the required key combi-
nation (listed below) and simultaneously
push the battery end of the communicator
down, so that the battery clicks in place.
Continue to hold down the keys until you see
progress messages or a confirmation prompt
on the display.
‡ In some cases the communicator will ask you
to confirm the action and you must press a
command button (e.g., Format / Cancel).
After the reset, the communicator will reboot
and start normally.
1) Check the file system
Key combination: Shift-ESC-(left arrow)
Symptoms: The Memory application (in the
System main view) shows too much (over 2
megabytes) or too little memory (even if
you have just deleted some documents), or
the communicator interface applications
crash when opening a document.
Caution: If there are problems in the file
system, the corrupted files will be removed.
If there are no problems, this operation
does not affect any documents or settings.
2) Delete temporary files
Key combination: Shift-ESC-(right arrow)
Symptoms: The communicator interface is
in a reboot cycle or a note saying that an
.ini file is corrupted is displayed.
Caution: All temporary files are removed.
The Document outbox is cleared, default
application settings are restored (for ex-
ample, the SMSC phone number, Internet
Access Point(s) and remote mailbox set-
tings are lost).
Stored documents are not affected.
3) Format file system
Key combination: Shift-ESC-F
Symptoms: The communicator interface is
in a reboot cycle or does not boot up.
Caution: Formatting the file system will
erase all data you have entered. This oper-
ation will restore your communicator in
the same state it was in at the time of
purchase.
Remember that backed up data can be re-
stored in all cases. If these measures do
not help, contact your local Nokia retailer.
