Receiver is on (LCD window lights)
• No sound • Alert light is OFF:
✓
"RF", "AF" and "BATT" legends do not appear in LCD...
• Receiver is in the Menu mode.
✓
"RF", "AF" level meters both show good signals.
• AF Level control on back of receiver not turned up (clockwise).
E 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
N
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-T310 body-pack only: Wrong input selected ( "INST" or "MIC" ).
Receiver is on (LCD window lights)
• No sound • Alert light is ON :
✓
"RF", "AF" and "BATT" legends do not appear in LCD, and LCD is flashing...
• Receiver is in the Edit mode.
✓
"RF" and "AF" level meters both show good signals.
• The transmitter audio level is too high
( "+3"/"+6" on receiver)
• Batteries may be weak. (Check "BATT" fuel gauge.)
✓
Only "RF" level meter shows good signal; no "AF" signal.
• Transmitter may be muted. (Note: Normally it takes several seconds for
the Alert light to turn off/on after the transmitter mute is switched off/on.)
✓
Neither the "RF" nor the "AF" level meter shows any signal.
• Receiver antennas not connected.
• Transmitter is turned off.
• Transmitter batteries are dead or missing.

Troubleshooting Guide
.
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; 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. (Recommended
squelch setting is the minimum/default value, 15 dB.) Tip: Use the Meter Hold
unction to help identify and resolve (or at least avoid) RF problem locations.
With transmitter on, received signal is noisy or contains extraneous sounds.
• Batteries may be weak. Check "BATT" fuel gauge 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.
