Loss of Audio

Last Updated: 08/28/2013
After programming, the radio has no audio from the built in speaker. 

This is a strange one since by default the radio puts audio to the internal speaker.  There is, however, a setting in the radio that is applicable when an external speaker is attached. It seems at times that this setting affects the radio even when an external speaker is not attached. 

In Settings | Common tab | Left Speaker (Right Speaker) 

By default these are set to External in anticipation of your attaching an external speaker.  According to the manual, the setting for this option should affect the radio only when the external speaker is attached. It seems, although it has not been thoroughly tested, that there is some combination of moves that allows this setting to affect the radio even when an external speaker is not connected.  

By setting Left Speaker and Right Speaker to Internal/External or Internal, audio will return to the internal speaker of the radio.
