While both speakers function together with the
secondary speaker enhancing intelligibility of the
received audio during typical radio operation, each
speaker has an independently-tuned frequency
response and volume level operation.
The secondary speaker also has a "whisper" mode
with a modified volume taper for quieter modes of
operation.
Note: If an external speaker or microphone accessory
is attached to the radio, neither internal speaker is
operational as audio is routed to the accessory.
The following methods are options on how to select
the audio speaker. The result of all the methods is the
same. You can use the options interchangeably
