Squelch Level Setting
The adjustable Squelch allows you to optimize the radio’s sensitivity. 
It also allows you to increase the sensitivity and receive weaker 
signals. There are 5 sensitivity levels. The squelch level is indicated by 
the      icon and bar icons next to it on the display.
1.  Press MON/FUNC until the current squelch level flashes and      
appears.
2.  Press UP/DOWN to increase or decrease the squelch level.
3.  Press PTT to set or MON/FUNC to continue set up.
Level 1 is the most sensitive level, which means the radio can 
receive a very weak signal. While at level 5, the radio can only receive 
stronger signals. In some cases the latter is preferable to prevent 
sensitivity to numerous strong signals in adjacent channels that 
might interfere (intermodulation). This can be especially true in the 
case of an environment with a high density of users.
