1. Power:
Turns the receiver on and off.
2. Channel
+
Button:
Press this button to change channel forward.
3. Channel
−
Button:
Press this button to change channel backward.
4. RF
Level
Indicators:
Five LEDs per RF antenna channel glow to indicate RF
signal strength. The more LEDs that glow, the stronger the received signal. If
none of these LEDs glow, no signal is being received. (Shown on external LCD
for MWR-200UFH model)
5. AF Level Indicators:
Five LEDs glow to indicate audio signal strength.
Green indicates normal operation. RED indicates approaching overload
condition. (Shown on external LSD for MWR-200UHF model)
6. Programmable
Display:
Can display channel number, frequency, RF level
and AF level indicators and/or volume.
7. Volume
Level
Control:
This control increases the receiver output level to match
the input sensitivity of an audio mixer or an amplifier. .
8. DC
OUT:
Connect the supplied cable to the receiver and the microphone,
it takes around 10 hours to charge. Only nickel-MH batteries my be recharged.
9. Antenna Input Connector:
TNC-type connectors provide connection to the
supplied antennas or to coaxial cable used with an antenna divider, antenna
boosters or remote antennas.
10. Antenna:
Fixed-length UHF antenna permanently mounted on rear panel.
11. Balanced Output:
3-pin XLR connector provides balanced low-impedance
output
12. Unbalanced Output:
6.3
ϕ
phone jack provides unbalanced low-impedance
output
13. Line/MIC
Switch:
Selects the XLR or ¼” Plug input
14. Squelch:
The squelch adjusts the output level to suppress the noise. The
higher squelch control, the lower the sensitivity of the receiver and decrease the
service area of the system. Set the squelch to minimum before turning the
receiver on.
15. DC
IN:
Input connector for the supplied AC adapter.

9. Trouble-shooting
Problem Solution
No sound
Check the power supply of the microphone and receiver.
Check that the transmitter and receiver are tuned to the same
frequency.
Check whether the hi-fi appliance is switched on and the receiver
output is connected to audio mixer or amplifier input.
Check whether transmitter is too far away from receiver or
SQUELCH control set too high.
Check whether receiver is located too near metal object or there
are obstructions between transmitter and receiver.
Sound interference
Check the antenna location.
When using 2 or above microphone sets simultaneously, make
sure that the chosen frequencies are not interfered.
Check whether the interference comes from other wireless
microphones, TV, radio and etc.
Distortion
Check the receiver volume level is set too high or too low.
Check whether the interference comes from other wireless
microphones, TV, radio and etc.
