Programming Speakerphone Mode
The DC640 includes an option for 2-way Speakerphone or Monitor Mode.
When “ MONITOR MODE” is enabled, voice t ransmission automatically stops
when the speakerphone key is pressed. MUTE will activate and the LED indica-
tor will illuminate when the speakerphone is turned on through the
SPEAKER
key, or the LINE key, or from an incoming Intercom call. The MUTE feature will
activate when the user switches from the handset or headset to the speaker-
phone during an active call.
When “ MONITOR MODE” is enabled, the MUTE feature can be turned OFF to
enable voice transmission on the speakerphone by pressing the MUTE key.
If the di rectory number s are switched or a call is pl aced o n h old and the n
released, the MUTE feature will be reactivated.
The “ 2-WAY SPEAKERPHONE” option all ows the voice to go out a utomati-
cally to the speaker without muting voice transmission.
