Weather Alert—When Weather Alert is enabled (See
Weather Radio section), the receiver is set to look for
weather alert tones either only on the current channel or
on all channels .
Headset Type—Allows you to choose which accessory
headset or microphone you are using with the unit, or
have the unit automatically detect the type. If you use
more than one type of headset or microphone, you need
to set the unit to Ask When Detected before changing
accessories.
NOTE: If the headset has a PTT (Push to Talk)
button, it must be pressed for the unit to detect the
headset.
VOX Level—Controls the sensitivity level of any
Voice Operated Transmission (VOX) accessory.
VOX accessories allow you to use the unit hands-
free. A lower VOX setting is recommended for quiet
environments while a higher VOX setting should be
used in noisy environments. Setting the VOX level to 5
is recommended for most environments, but it may be
necessary to adjust the level to achieve the desired voice
trigger level. You will hear yourself talking in the headset
when transmitting successfully using VOX.
Microphone Sensitivity—Allows you to set the
sensitivity of the internal microphone and the sensitivity
of a headset microphone. When selected, a sensitivity
adjustment slider displays. Adjusting the sensitivity
requries the assistance of another radio user to advise of
the voice quality received while adjusting the slider.
