Information about transmit power and squelch setting in the bodypack receiver:
Select a low transmit power if the transmitter and receiver are in close proximity to each other; the squelch in the receiver should also be set to a
low level as a guide. For greater distances between transmitter and receiver, select a higher transmit power and adjust the squelch in the receiver
accordingly. For more information on setting the squelch, refer to the "SQUELCH SETTING" section under "POCKET RECEIVER OPERATION" in this manual.
In any case, make sure that the transmitter and receiver have direct eye contact and that no obstacles between the transmitter and receiver can
interfere with radio operation.
Depending on the situation, different settings may be required for trouble-free operation. Please note that when other transmitters are used in the
vicinity this increases interference that may cause problems with the radio connection. Selecting a different radio frequency can avoid interference
in this case.
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.
AUDIO SETTINGS
Press the transmitter's rotary-push encoder (MENU) to enter the main menu, then turn the encoder to select AUDIO SETTINGS (highlighted). Press the
encoder again to enter the sub-menu and select the desired sub-menu item by turning the encoder. Con昀椀rm your entry by pressing the encoder.
If you change a value by turning the encoder, con昀椀rm the value change by pressing the encoder. The sub-menu items and the corresponding
information can be found in the following table. Brie昀氀y (!) press POWER to return directly to the main display; after about 12 seconds of inactivity
the main display will appear automatically.

Setting the operating mode to Mono / Stereo
The selected operating mode is shown in the
display of the receiver (M = Mono, S = Stereo)
000 – 100 For an optimum signal-to-noise ratio, set the signals
left and right as high as possible, but make sure the
000 – 100
PEAK indicator does not appear in the display, or only
brie昀氀y, in order to avoid signal distortion. Adjust the
output level of the playback device if necessary.
ON = enabled (recommended)
OFF = disabled
MONO = Input signals left and right are summed to a mono signal.
Shift the signal to the left or right on the receiver (BALANCE).
STEREO = playback of the input signal in stereo. Setting the balance
on the receiver (BALANCE)
Activate the STEREO mode in the transmitter even if you want to
use the FOCUS mode in the pocket receiver.
