Over-the-Air Programming (OTAP)
Your radio can be updated by your dealer remotely, via OTAP, 
without needing to be physically connected. Additionally, some 
settings can also be configured via OTAP. 
While undergoing OTAP, the LED blinks green. 
NOTE: When the radio is receiving high volume data, the 
channel is busy. A PTT button press at this time causes 
a negative tone to sound. 
Once the programming is complete, a tone sounds, and your 
radio restarts (powers off and on again). 
Utilities
Setting the Squelch Level 
You can adjust your radio's squelch level to filter out unwanted 
calls with low signal strength or channels that have a higher 
than normal background noise.

calls and/or background noise. However, calls from remote 
locations may also be filtered out.
Procedure:

operating in tight squelch.
