ADJUST NOISE BARRIER (SQUELCH)
The 3-stage squelch prevents unwanted noise when the transmitter is off. In addition, sudden noise is suppressed if the signal transmitted from the
transmitter to the receiver is not strong enough (e.g. due to the distance being too great). CAUTION! BEFORE adjusting the squelch, make sure that
the receiver volume is set to the lowest possible level, as changing the squelch threshold may cause loud background noise that can potentially in-
昀氀ict hearing damage as well as damage to connected headphones or earphones. Set the squelch (when the transmitter is off) to the lowest setting
where ambient noise is still effectively suppressed (LOW / MID / HI). In the "HI" setting, the transmission range may be reduced under unfavourable
circumstances. Press SEL (MENU) for about 2 seconds to enter the main menu, then press SEL repeatedly to select SQUELCH (highlighted) and press
 to con昀椀rm. Now select the desired setting by pressing  (repeatedly if necessary). To exit, press SEL, select EXIT again by pressing SEL and press
 to con昀椀rm. The main display will automatically appear after approximately 5 seconds of inactivity.
SET DISPLAY BRIGHTNESS (DISPLAY)
Press SEL (MENU) for about 2 seconds to enter the main menu, then press SEL repeatedly to select DISPLAY (highlighted) and press  to con昀椀rm.
Now select the desired setting by pressing  (repeatedly if necessary) (HI = brightness high / LOW = brightness low). To exit, press SEL, select EXIT
again by pressing SEL (repeatedly if necessary) and press  to con昀椀rm. The main display will automatically appear after approximately 5 seconds
of inactivity.
LEAVE MAIN MENU (EXIT)
To exit the main menu and return to the main display, select EXIT (highlighted) by pressing SEL repeatedly (highlighted) and then press . After
approximately 5 seconds of inactivity, the main display will appear automatically.
BATTERY STATUS
