Telephone Operation
When any telephone zone rings (the local buzzer sounds intermittently, and the green zone
LED and Incoming Call LED flash) press that zone's button (on the selector panel QAZT-
5348DS) once to answer. Once any one zone has been answered, calls from any other zone
will cause that zone's green LED and the Incoming Call LED at the master telephone to flash
and the buzzer will sound.
Press the answered zone's button once again to hang up. (Note that the telephone zone will
hang up automatically if all handsets on the zone are placed back on the hook).
