PL Reverse Burst
PL Reverse Burst causes a Private Line (PL) 
code to be sent at the end of a transmission 
once the PTT button is released. This sub-
audible tone causes the receiving radio to mute 
its speaker before loss of a carrier is detected. 
Muting the speaker eliminates unwanted noise 
(squelch tail) during loss of carrier detection.
Choices available are: 180/240.
Alternate Battery Selection
The radio is capable of supporting multiple 
batteries solutions; therefore, the user can 
configure a battery type when using the 
accessory battery pack tray, only when the 
radio does not detect a valid battery type on its 
own. Choices available are: Alkaline, Nickel, 
and Lithium Ion.
