8 Troubleshooting

The telephone tests for optiPoint 500 are described in Section 3.6.

Troubleshooting for optiPoint 500 can be carried out on site by replacing the faulty equipment or with the appropriate spare parts.

8.1Test Loops 3 and 4

Hicom/HiPath provide diagnostic modes that are supported by the telephone (test loops 3 and 4).

8.2Reboot

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.
