8.4 UNIVERSAL DEVICE CONNECTOR (UDC)
The Universal Device Connector (UDC) provides connections for external accessories such as a headset
or a speaker-microphone. The UDC is located on the right side of the radio (opposite the PTT Button).
When the radio is locked in a vehicular charger the UDC provides the audio and control connections
between the radio and the vehicular charger. The UDC facilitates programming and testing the radio. The
UDC pins perform different functions depending on the accessory attached to the UDC.
