Keypad Functions with Digital Phone System
ON/OFF
Pressing the ON/OFF key turns the Conference Phone on to connect a call, or turns it off to
terminate the Conference Phone conversation. When the Conference Phone is on, green LEDs
illuminate by all active microphones.
With a digital telephone system, Conference Phone calls go through the digital telephone
connected to the DT-104 Digital Interface, and that digital telephone’s handset must be off hook
for the duration of the call. When the Conference Phone is turned on, it disables the microphone
in the digital telephone handset so conversation is conducted only through the Conference Phone.

When using the Conference Phone with a digital telephone system, you must dial calls on the
