Troubleshooting Guide

Receiver is not on (LCD window does not light).

•Receiver Power switch is not pressed in.

•Small DC power cord from included in-line power supply is not plugged into jack on back of receiver.

•The power supply is not plugged into AC power outlet.

•AC power is not present at the AC outlet.

Receiver is on (LCD window lights)

•No sound:

“RF” and "AF" level meters both show good signals.

•AF Level control on front of receiver not turned up (clockwise). [See p. 4.]

Note: If the “AF” level meter shows a good signal on the receiver when the transmitter is receiving audio input, and the AF Level control is turned up, then the problem is in connections to, or control settings on the mixer, amplifier, etc.

Only “RF” level meter shows good signal; no “AF” signal.

•No sound input to mic.

•ATW-T161 body-pack only: Wrong input trim selected (“GT”or “MIC”). [See p. 5.]

Receiver is on (LCD window lights)

•No sound:

“RF” and “AF” level meters both show good signals.

•The transmitter audio level is too high [See p. 4 & 5]

Neither the “RF” nor the “AF” level meter shows any signal.

•Receiver antennas not connected.

•Transmitter is turned off.

•Transmitter is set to a different frequency.

•Transmitter batteries are dead or missing.

Receiver is on (LCD window lights)

•Distorted sound:

“RF” and/or “AF” level meters may show good signals.

•The transmitter audio level is too high. [See p. 6 & 7.]

•Received RF level may be too low (only one or two bars).

•Batteries may be weak; check “BATT” condition indicator.

[See p. 5]

Momentary loss of sound/noisy sound as transmitter is moved around performing area.

•Transmitter and receiver antennas not in line-of-sight (or perhaps too far apart). Adjust positions of units so they are visible to each other/closer together.

If problem persists. use remote antennas located closer to the transmitter location.

•Signal blockage or interference from large metal objects, other wireless units located too close and/or on incompatible frequencies, computer or lighting equipment.

•Squelch setting may be set “tighter” than it needs to be.

[See p. 6]

With transmitter on, received signal is noisy or contains extraneous sounds.

•Batteries may be weak. Check “Battery condition indicator and “RF” meter level.

•Local TV transmissions on this frequency.

•Nearby sources of RF interference, such as computers, lighting equipment, etc.

•Two transmitters may be operating on the same frequency. Locate and turn one off or change its frequency.

•In multiple-system use, two (or more) incompatible frequencies may have been selected. Refer to the suggested multi-channel frequency combinations. on supplement sheet,
