TRANSMITTER OPERATION
To establish a radio connection between transmitter and receiver, the frequency group and channel or radio frequency of both devices must match.
When putting the wireless transmission system into operation, be sure to position the receiver in the direct line of sight of the transmitter.

After switching on the transmitter, the greeting "Welcome" is displayed brie昀氀y. The main display then appears with the following information:
individual user name, preset number, level of the audio input signals with peak display, frequency group and channel (GR.xx and CH.xx) and the
current radio frequency in MHz.

Starting from the main display, the overall volume can be adjusted directly by turning the rotary-push encoder MENU from 00 to 50. The display
changes automatically to the corresponding display when the encoder is turned. After about 3 seconds of inactivity, the main display is automati-
cally restored; pressing the encoder switches to the main display immediately.

BATTERY COMPARTMENT
20
To replace the batteries, open the battery compartment of the pocket receiver by simul-
taneously pressing both markers on the sides of the battery cover and pulling it downwards
from the housing as far as it will go. Remove the used batteries and replace with new
batteries (2x AA/LR6, alkaline), following the diagram in the battery compartment. Now slide
the battery compartment cover back onto the housing until it clicks into place. If you do not
use the receiver for a long time, remove the batteries to prevent damage to the receiver
from leaking batteries.
21 BELT CLIP
On the back of the pocket receiver there is a belt clip that can be used to attach the receiver
to a trouser waistband, belt or similar.
