Using the Test Feature
When the telephone is initially powered up, the green light next to the TEST button
flashes if the telephone is not (or not yet) able to communicate with the switch.
The light changes to steady green when the switch link is operational. After a
short period of time, the light turns off in order to conserve power.
NOTE:
If the light next to TE ST does not come on, the telephone is not receiving
power from the switch.
The Test Feature
To test the lights and the display on your telephone:
5. While on-hook, press and hold down TEST.
■ Green light next to TEST goes on.
NOTE:
If the green light next to TEST flashes rather than going on
steadily, it means that the telephone is not able to
communicate with the switch.
