Reboot

The first time the telephone is turned on or is reset by the local firmware, this reboot is repre-
sented visually as follows:
All LEDs on the telephone are activated for 20 ms (+/- 5 ms).
●
All LEDs on connected key modules are activated for 20 ms (+/- 5 ms).
●
All pixels on the screen are activated for one second.
●
These procedures show that the telephone was rebooted and has completed its self-test pro-
cedures.
They do not indicate that communication has been established with the Hicom/HiPath.
After communication has been established with Hicom/HiPath, the Hicom/HiPath controls the
screen and LEDs (excluding entry), thus showing the user that the telephone is ready for op-
eration.
