RECEIVER UNIT
Operation
Switch on the wireless microphone receiver unit by pressing the POWER switch and the POWER
light will illuminate to show the receiver unit is working. Raise the aerial to the maximum height. The
positioning of the aerial is not critical for performance, ideally it should be fully extended. Switch ON the
microphone, checking that the red LED comes on for a second and then goes off. When the microphone
is ON, the SIGNAL light will illuminate on the receiver unit.
The wireles microphone is now ready for use, adjust the volume and tone levels of your amplifier system
as well as the receiver and the bodypack as required. When the wireless microphone is not being used
turn OFF the microphone.
Note that switching the microphone on and off can cause interference that will be heard if the mic
volume level of the amplifier system still set high.
BODYPACK AND HEADSET
Operation
Push the battery cover on the front of the bodypack as per the diagram above and install a 9V battery,
taking care to fit it with the correct polarity.
Check the battery by switching the microphone ON. The LED will come foe one second and then go
off, this indicates correct operation. If the LED stays on or is dim, this indicates the battery is low and
should be changed. If the LED does not come on at all, this indicates the battery is dead and should be
changed.
You can adjust the volume control on the bodypack until you get the sufficient sound from your speaker.
