PROBLEM POSSIBLE CAUSE SOLUTION
Microphone
• No sound
• Lights on
1) The transmitter is out of range.
2) Microphone switch is off.
3) Microphone volume is turned down.
4) Batteries in the microphone are not
installed properly.
5) Receiver is not connected to an amplifi-
er, mixer or other sound system.
6) Microphone frequency is not synched
to the receiver.
1) Operate the device in the effective range.
2) Turn on the microphone switch.
3) Turn up the microphone volume on the
receiver.
4) Put batteries in the transmitter. Make sure
the positive and negative ends of the bat-
teries are pointed in the right direction.
5) Connect a cable from the receiver to a
microphone input of a sound system.
6) Use the IR synch function to synch the
microphone with receiver.
Sound
• Distorted
sound
• Feedback
• Drop outs
1) The microphones are too close
together.
2) Batteries are low.
3) Microphone volume is too high.
4) Distortion from other electric wave.
5) Frequency interference.
1) Create distance between the microphones.
2) Replace the batteries.
3) Reduce the volume of the microphone.
4) Move the receiver away from other electric
equipment.
5) Try changing the channel of the micro-
phone. Both transmitter and receiver must
match frequencies for operation.
IR Sync
• Microphnoe
not syncing
with receiver
1) The transmitter is pointed in the wrong
direction.
2) The transmitter is not being pointed at
the right location on the receiver.
3) Make sure the transmitter is close
enough to help align.
4) There is a second transmitter or
receiver already on nearby.
1) Make sure transmitter is pointed in right
direction. The IR window on the transmitter
shown on pages 10-11 of the manual needs
to be pointed at the IR sync window loca-
tion on the receiver. Both of these windows
should be facing each other within about
1/2" or less when syncing.
2) Make sure the transmitter is pointed at the
right location on the receiver. See pages 6,
8 or 9 to locate the IR window of receiver. It
should say IR next to the IR sync window
on your receiver.
3) The transmitter window is not aligned
properly to the receiver during the syncing
process. Position within 1/2" or less. The IR
sync windows must be aligned when the
receiver is in the IR sync mode. See page
12 for details.
4) Turn off all nearby transmitters or receivers
that are not currently going through sync
process. An additional transmitter that is
turned on may interfere with the syncing
process.
