RECEIVER OPERATION

When operating the wireless transmission system, be sure to place the receiver in the line of sight of the transmitter. For optimal reception,
perform the automatic frequency search after switching on the receiver. Leave the corresponding transmitter off, but other radio systems turned
on, if necessary. For the operating steps, see FREQ AUTO RUN.
DISPLAY
After switching on the receiver, "WELCOME" appears for a short time, then the main screen displays the following information: individual username,
battery status, radio signal level (RF), active antenna (A / B), level of the audio signal, frequency group and channel (GR.xx and CH.xx) and the radio
frequency in MHz.
· Individual username
· Radio signal level and active antenna
· Frequency group and channel
IR SYNC RUN
To synchronize the transmitter with the radio frequency set in the receiver and the individual username, bring the infrared port of the transmitter
in direct visual contact with the infrared port of the receiver (distance approx. 10 cm) and turn on the transmitter. Now press the pressure rotary
encoder of the receiver (MENU) to access the Edit menu and select the menu item IR SYNC RUN by rotating the encoder (light background). Press
again on MENU to initiate the synchronization process. After a few seconds, the process is completed and the display of the transmitter switches for
a short time to "IR SYNC ", confirming successful synchronization. To cancel the operation, press MENU. Press briefly(!) on POWER to return directly
to the main display. After about 10 seconds of inactivity, the main display is automatically shown.
FREQ AUTO RUN
Automatic frequency search (frequency scan) to determine an interference-free radio frequency in the current environment and to allow for
optimal reception. For this purpose, leave the corresponding transmitter off, but other radio systems turned on, if necessary. Press the pressure
rotary encoder (MENU) to access the Edit menu and select the menu item FREQ AUTO RUN by rotating the encoder (light background). To initiate
the process, press again on MENU. Progress is now indicated on the display by an animation and the scanning process is completed after approx. 30
seconds (to cancel, press MENU). The resulting frequency is automatically enabled and, as in "IR SYNC RUN", you can now switch on the transmitter
and synchronize it with the receiver. Press briefly(!) on POWER to return directly to the main display. After about 10 seconds of inactivity, the main
display is automatically shown.
