Selecting the Audio Speaker
Your radio must be preprogrammed to allow you to
use this feature.
This feature allows you to select the speaker route for
the radio's audio from either the main or the
secondary speaker using the radio profile settings.
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
depending on your preference and the programmed
functions.

backlight as needed, if poor light conditions make the
display or keypad difficult to read.
Depending on how your radio is preprogrammed, you
can also maintain a minimum backlight level on the
radio's front display.
