24/90V MESSAGE WAITING LAMP
If your phone is installed behind a Message Waiting enabled PBX, you will need to set the
MW switch in order to receive the Message Waiting indication.
1. Locate the switch on the bottom of the telephone.
2. For 90V PBX Message Waiting Indication, move the switch to the position marked
“90V”. For 24V PBX Message Waiting Indication, move the switch to the position
marked “24V”. If connecting directly to telephone lines, move the switch to the center
“OFF” position.
Warning: Setting this switch in a position other than OFF can cause this phone to
function incorrectly. When enabled, this feature is for PBX systems, and not meant for
direct Central Office (CO) interface. If connecting to CO telephone lines, make sure this
switch is set to OFF.
