TROUBLESHOOTING

If you encounter any problems in the operation of your Shure Wireless Microphone System, first make certain

you’ve followed the ABC’s of proper wireless microphone operation:

Antennas -

Make certain the transmitter antenna is dangling vertically. Make certain the receiver antennas are

properly connected, located and mounted.

Battery -

Make certain the transmitter battery is fresh and of the right type. And while you’re at it, make cer-

tain the receiver power converter is connected to a functioning power source.

Controls -

All receiver and transmitter controls should be properly set for the desired operation. Recheck all

settings for correct system setup.

If you still have a problem, follow the advice below. If you’re unable to solve the problem, contact your dealer or

Shure’s Service Department.

PROBLEM

Movement around the performing area produces

intermittent “swooshing” sound or complete loss of

signal (dropout).

Make certain both antennas are properly connected,

mounted and positioned for optimum reception. Mini-

mize transmitter-to-receiver distance.

SOLUTION

Audio signal sounds distorted at medium to high

input levels.

Reduce transmitter audio gain.

Receiver picks up other (interfering) radio signals.

Make certain transmitter is turned on. If problem per-

sists with transmitter on, it may be necessary to

change system operating frequency. (Another

transmitter, possibly a VHF-TV transmitter, may be

operating at the same frequency.)

Audio signal contains undesirable whistling or

chirping sounds, or sounds garbled.

Audio signal contains undesirable hissing sounds.

One wireless microphone produces a lower output

than other wireless microphones in the same sound

system.

Movement around the performing area produces an

undesirable squeal or howl (feedback).

Maximum operating distance (transmitter to receiver

antenna) seems less than when system was new.

Short transmitter battery life.

Receiver not functioning.

Two transmitters may be operating simultaneously

on the same frequency. Turn one transmitter off. If

problem persists, may be caused by other radio

signals (see above).

Transmitter and/or receiver gain may require

increase (setting is too low).

Relocate the speakers. Reduce the receiver and/or

and/or sound system gain. (Professional equalization

may be required.)

Transmitter antenna may require replacement.

Receiver antennas may require relocation.

Make certain replaceable batteries are alkaline

(Duracell MN1604 or equivalent). Make certain

rechargeable batteries (nicads) are 8.4-volt types.

Make certain receiver power converter is connected

to functioning ac source.

Make certain rear-panel 0.5A, 250V, 3AG fuse is not

blown.

REMEMBER:

Many apparent problems are due to improper setup and operation. Make certain you have followed

instructions carefully before contacting Shure for service.
