Problem

Solution

No receiver sound;

RF and Audio Level

meter LEDs glow-

ing.

Turn up the receiver audio output Level control.

Check for proper connection between receiver and microphone

mixer.

Talk into the microphone and observe the receiver audio level

LEDs. If they glow, the problem is elsewhere in the sound system.

Received signal is

noisy or contains

extraneous sounds

with transmitter on.

Check transmitter Power/Battery Fuel Gauge and replace battery

if power is low.

Remove local sources of RF interference, such as lighting equipment.

If using a guitar or other instrument, make sure it is connected to

the U1 with a Shure WA302 adapter cable.

Two transmitters may be operating on the same frequency. Locate

and turn one off or change frequency.

Signal may be too weak. Reposition antennas closer to the trans-

mitter.

Adjust receiver squelch control.

Noise from receiv-

er with transmitter

off.

Adjust receiver squelch control.

Remove local sources of RF interference, such as lighting equipment.

Try using another frequency.

Reposition the receiver or antennas.

Momentary loss of

sound as transmit-

ter is moved

around performing

area.

Reposition receiver and perform another “walkthrough” test and

observe the RF level or Diversity signal indicators. If audio drop-

outs persist, mark these “dead spots” in the performing area and

avoid them during the performance.

Decrease squelch control setting, even though noise in “dead

spots” may increase slightly.

Move antennas to a remote location (use UA830 kit).

SPECIFICATIONS

Refer to the supplement that came with your system.
