RECEIVER FUNCTIONS
1. Antennas: Fixed-length UHF antennas permanently mounted on the front panel. Put these in vertical
position during use.
2. Power Indicator: The indicator LED lights when the receiver is ready to operate.
3. AF Indicator: The indicator lights to indicate that an audio signal is received.
4. Diversity A. B Indicators: These LEDs lights to show which antenna currently receives the RF Signal.
5. Balanced Output: 3-pin XLR connector provides balanced low-impedance output. If your audio mixer is
equipped with a balanced input, it's better to connect the receiver using this XLR-output. Don't forget to
set the mic/line switch (7) in the desired position.
6. Unbalanced Output: Unbalanced 6.3mm mono jack audio output. Can be used to connect a guitar am-
plifier or any other unbalanced audio mixer input. Don't forget to set the mic/line switch (7) in the desired
position.
7. Mic/Line Switch: used to select the output level of the XLR balanced connector or 6.3mm unbalanced
phone jack. It can be set for microphone (-20dB) or line-level (0dB).
8. Channel Selector: Use this rotary switch to choose one of the 16 available channels. Note that the se-
lected channel on the receiver should always be identical to that of the transmitter (hand mic or belt
pack).
9. Squelch Adj.: to prevent unwanted and disturbing noises, the squelch mutes the audio output of the
receiver when the detected RF-signals of the are too weak. With the squelch control you can determine
the minimum RF-signal level before audio output is not suppressed anymore. Setting the squelch too
high will reduce the range (max. distance) of the system. The squelch is already set in the factory so
normally you don't need to change it. If you should adapt the squelch level for any reason, please set it
to minimum before turning the receiver on and then slowly adjust using trial and error method.
10. DC IN: DC input connector for the supplied AC adapter.
11. Charger output: connect the supplied charger cable between the receiver and the microphone/belt-
pack. It takes around 10 hours to recharge the batteries. While charging, the "low battery" indicator on
the transmitter is flashing.
Important note: be sure to insert rechargeable batteries (preferable "Ni-MH" type) in the transmitter be-
fore you connect the charger! NEVER charge normal batteries like for example "Alkaline" type) !!!

HANDHELD MICROPHONE FUNCTIONS
1. Grille: Protects the unidirectional dynamic microphone capsule and helps reduce breath sounds and
wind noises.
2. Low Battery LED: this LED indicates the battery life status. When the transmitter is switched ON:
 LED is permanently on: the battery is still in good condition.
 LED flashes quickly: indicates that the
battery has insufficient power and
should be changed soon.
 LED fails to light: the battery is either
dead or not positioned correctly. You
should correct the positioning or change
the battery.
3. On/off Switch: press this button several
seconds to turn transmitter power on/off.
4. Battery Compartment: Insert two AA
rechargeable or dry (Alkaline) batteries in-
to the compartment. Make sure that the
polarity of batteries is correct.
5. Channel Selector: Use this rotary switch
to choose one of the 16 available chan-
nels. Note that the selected channel on the
receiver should always be identical to that
of the transmitter.
6. Battery Cover: unscrew it gently and
slide it down to open the battery compartment or have access to the channel selector (5).
7. Antenna: Built-in high gain helical antenna.
8. Charger Input: connect the supplied charger cable between the receiver and the microphone. It takes
around 10 hours to recharge the batteries. While charging, the "low battery" indicator is flashing.
Important note: be sure to insert rechargeable batteries (preferable "Ni-MH" type) in the transmitter be-
fore you connect the charger! NEVER charge normal batteries like for example "Alkaline" type) !!!
BELT PACK FUNCTIONS
1. Mini XLR Connector: The included electret lavalier microphone (or optional headset) is inserted into
this connector.
2. On/off Switch: press this button several
seconds to turn transmitter power on/off.
3. Low Battery LED: this LED indicates the
battery life status. When the transmitter is
switched ON:
 LED is permanently on: the battery is
still in good condition.
 LED flashes quickly: indicates that the
battery has insufficient power and should
be changed soon.
 LED fails to light: the battery is either
dead or not positioned correctly. You
should correct the positioning or change
the battery.
4. MIC/LINE switch: used to change the sen-
sitivity or the mini XLR-input (1):
 MIC: use this position when a headset or
lavalier microphone is connected.
 LINE: use this position when a line level
unit (guitar, instrument, audio player, ...)
is connected.
5. Antenna: Permanently connected helical
antenna.
