Figure 1: Front and Rear Panels

1. Antenna: Fixed-length UHF antenna
permanently mounted on the front
panel.
2. PWR: The indicator LED
illuminates when the receiver is ready
to operate.
3. AF: The indicator LED
illuminates to indicate that audio
signal has been received.
4. DIVERSITY A - B: This indicator LED
illuminates to show that antenna has
received the RF Signal.
5. BALANCED: 3-pin XLR output
connector provides balanced low-
impedance output.
6. UNBALANCED: 6.35mm mono jack
audio output for connecting to e.g. a
guitar amplifier.
7. MIC/LINE: Switch to select output of
XLR balanced connector or 6.35mm
unbalanced phone jack. This can be
set for microphone (-20dB) or line-
level (0dB).
8. CHANNEL: Rotary selector switch
with 16 different selectable
frequencies.
9. SQ: Adjusts the output level to
prevent external noise. Setting the
Squelch too high will reduce system
range.
10. DC INPUT: Input connector for
the supplied AC/DC adaptor.

INSTALLATION:

• Do not use two transmitters set to the same frequency.
• Always use good quality batteries to avoid any damage that may result from a defective leaking battery.
• Install the receiver in locations away from metal objects and avoid obstructions between the transmitter and receiver.
• To avoid interference, do not place the receiver adjacent to TV, radio, and other wireless appliances where possible.
• Set the transmitter and receiver to the same frequencies. To do this, change the channel frequency selection switch so that the
transmitter and receiver are set to the same frequency. These will provide optimum performance with multiple systems.
• Never use the balanced and unbalanced audio outputs at the same time.This may cause signal loss or increased noise.
• Set the squelch to minimum before connecting the receiver power supply.
• Connect the a.c. adaptor and the power light should illuminate.
• Switch on the transmitters (see pages 3 and 4 for transmitter information). Ensure the transmitter is at least one metre from the
receiver.
• Check for sound quality by moving the transmitter around the area where you wish to use the system, to look for dead spots. If you
find any dead spots, change the receiver position.
Note: If user needs to set up a multi-receiver system, please keep your previous receiver-microphone pair powered on. Then
repeat the setup procedure for the other receiver – transmitter pairs.
