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-
flict 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 confirm. Now select the desired setting by pressing
(repeatedly if necessary). To exit, press SEL, select EXIT again by pressing SEL and press
to confirm. 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 confirm.
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 confirm. 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
The battery charge status is shown in the display and continuously updated (main display A).
appears when the batteries are fully charged,
indicates a charge status of approx. 70% and
indicates a charge status of approx. 30%. As soon as a critically low charge status is
reached, the display changes to "LOW BATTERY" approximately every 3 seconds, the
symbol for “low battery” appears and a pure tone at
approx. 500Hz is emitted via the headphone socket as an acoustic warning signal. Replace depleted batteries immediately.
