Receiver
1. Connect the DC POWER ADAPTER to the receiver’s DC INPUT
then plug the other end of DC POWER ADAPTER into the WALL
OUTLET
2. Connect one end of ¼ “ to ¼ “ cable to receiver’s UN ALANCE
AUDIO OUTPUT (MIX) and the other end to a mixer. If you are
using the ALANCE AUDIO OUTPUT, use a XLR to XLR cable or
XLR to ¼ “ cable
3. Install the antenna into each antenna socket on rear panel, then
fasten the antenna towards the right side till the antenna is
vertical with ground
4. Push/Open the microphones handle/bodypack cover to check
to see if there are batteries. If not, install the batteries into the
microphones with the negative and positive end of the battery

electric wave
-
Separate the
microphone further
away
-Replace the batteries

of the microphone
-Move the receiver
away from electric
equipment
