●

Notes on the optiPoint acoustic adapter
Section 10.5.4 contains details on a possible additional external power supply.
●
The internal components of the optiPoint terminal are deactivated in speakerphone mode
●
if an external microphone and an external loudspeaker are used (sense lead).
optiPoint 500 basic does not support the connection of an external microphone to the op-
●
tiPoint acoustic adapter.
The speakerphone mode selection is independent of whether the internal or an external
●
speakerphone is used. External speakerphones have precedence over internal speaker-
phones with the exception of manual intercom and signaling procedures.
The internal microphone, the transmitter inset and any microphone connected to the opti-
●
Point acoustic adapter are muted in the "Mute" audio state.
