Radio Programming for Private Handset Mode

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 
radio’s programming application. Refer to the online help of the programming application 
for more information.

If private handset mode is programmed, then no audio will be heard from the speakers if 
the handset is unplugged.
