If private handset mode is required, the radio needs to be programmed to
mute the audio power amplifier when the handset is out of the cradle. The
audio path is then only through the RX AUDIO line to the handset earpiece.
The following table shows the settings required in the Programmable I/O
form of the TM8000 Programming Application. Refer to the online help
of the programming application for more information.
Note
If private handset mode is programmed, then no audio will be
heard from the speakers if the handset is unplugged.
