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.
