Features
at the light next to the button for your co-worker's extension
before you use the Send/Remove Message feature. See "TO
Send Messages Consoles with DSS)".
The message status light on the DSS reflects the status of
operator-sent messages only. If a co-worker's message light
is on because a fax is waiting or another co-worker has left a
message, the DSS button light is not on, and using
Send/Remove Message does not turn the co-worker's
message light off.
NOTE:
To check the status of your co-workers' message lights,
you must have a DSS attached to your console. If you
send a message, you may be turning off the message
light turned on by another operator. When you cannot
check message status, use Leave Message if your co-
worker has a display telephone. (See "Leave Message").
To Send Messages (Consoles without a
DSS)
