Receiving an Answer Detection Alarm
<DET> lamp
and key If your system is equipped with an answer detection unit,
the DET lamp lights when the unit is out-of-service. If you
notice that the DET lamp is lit, contact your administrator
immediately. The <DET> key stays lit until the unit is
restored to service.
Receiving a Wakeup/Reminder Call Alarm
<WAL>and
<RAL> lamps
and keys The wakeup call alarm (WAL) or the reminder call alarm
(RAL) lamp informs you when a wakeup or reminder call
has not been answered. Depending on how your phone
system is set up, the visual alarm may be accompanied by
distinctive ringing, which is disabled when you
acknowledge the wakeup alarm.
If a wakeup/reminder call is not answered the first time,
the system waits five minutes, then tries again. If the call
is not answered the second time, the system waits another
five minutes and tries a third time. You receive a
wakeup/reminder alarm after the third attempt.
