To reset the communicator
1 Close the cover.
2 Remove the battery.
3 Remove the memory card if inserted.
4 Place the connector end of the battery in the battery cavity, but do not
press the other end in place yet. Do not let the battery slip from its place.
The connector end is the one with the four metal strips.
5 Open the cover.
6 Press and hold down the required key combination (see below in this topic
4) and simultaneously push the battery end of the communicator down, so
that the battery clicks into place. Hold down the keys until you see
progress messages or a confirmation prompt on the display.
7 In some cases you must confirm the action by pressing a command button.
After the reset, the communicator will reboot and start normally.
