Telephone Operation
1. 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-5302DS) 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.
2. 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).
