3. Slide off the battery compartment cover on the rear of your mic (by pushing downwards towards the base) or open
the bodypack battery compartment.
4. Now turn ON your mic/bodypack transmitter.
5. Ensure that there is a short and direct line-of-sight between the transmitter infrared connect window (14. on the
mic or 20. on the bodypack) and the receiver’s infrared connect window (7.). In other words, point the open battery
compartment of the mic or bodypack towards the middle of the receiver’s front window.
6. Press and hold the IR connect button on the receiver (6.), the infrared connect window’s LED indicator will flash
momentarily and then the RF LED indicator (4.) will light up green. The receiver and mic or bodypack are now
connected (channel A = frequency 1 / 863MHz). To test the connection, speak into the mic, the AF LED indicator
should light up orange to indicate that the unit is receiving an audio signal. To test the bodypack, attach one of the
mics or an instrument to the bodypack input socket (15.), turn up the volume control (18.) and speak or play, the AF
LED indicator should light up orange to indicate that the unit is receiving an audio signal.
Whenever the mic/bodypack transmitter or system are turned off and then turned on again, the ACT connection
should remain in place until you change the channel frequency on the receiver. This allows the mic/bodypack to be
turned on and off during performance. If for any reason the connection is lost, simply repeat from step 1.
To connect the second microphone/bodypack to Channel B, repeat the above procedure from step 1. (but choose a
different frequency in step 2.). To avoid interference between the two channels, ensure that your chosen
frequencies are not too close to each other (e.g. 1+2), instead choose two separated frequencies e.g. 1+14 or 5+15.
When both channels have transmitters connected, turn up the channel volume controls on the receiver and the
volume controls on your connected mixer/amplifier/PA speaker system, you should hear the signal coming through
and you can adjust the volumes to suit your performance.
VERY IMPORTANT - if you wish to run 2 receivers and 4 transmitters together and to avoid interference between
the two systems, it is recommended you use the following setup:
Unit 1 - set channel A to frequency 1 and set channel B to frequency 14.
Unit 2 - set channel A to frequency 5 and set channel B to frequency 15.
Troubleshooting
If you are having trouble connecting the mic/bodypack transmitters to the receiver, first check whether you have
fresh working batteries correctly installed. Weak or dead batteries will NOT be able to make a connection. If you still
fail to connect the two, start by turning both units OFF for 5 seconds, then turning the receiver only back on and
starting the connection procedure from step 1.
