Troubleshooting
LED NOT LIT • Battery not installed or depleted.
• Power not turned on.
NO SOUND IN HEADPHONE
• AUDIO LEVEL turned all the way down.
• Headphone plug not inserted fully.
• Defective headphone or connector
• Transmitter not operating. (See separate transmitter manual.)
• Receiver not on the same frequency as the transmitter.
DISTORTED SOUND
• Transmitter gain (audio level) is far too high. Refer to the operating
instructions section in the transmitter manual for details on gain
adjustment.
• Receiver output may be mismatched with the headset or
earphone. Adjust audio level on receiver to the correct level
for the headset or earphone.
HISS AND NOISE, AUDIBLE DROPOUTS • Transmitter gain far too low.
• Receiver antenna missing or obstructed.
(Headphone cable is the antenna.)
• Transmitter antenna missing or obstructed.
• Operating range too great.
• Transmitter antenna obstructed. Move transmitter antenna and/or
receiver to a position with a line of sight between the transmitter
antenna and the receiver.
• Receiver antenna (headset cord) may need to be repositioned for a
line of sight to transmitter antenna
SHORT RANGE • Receiver headphone cable is also the antenna. Make sure the cable
is not coiled or wound up or wrapped around the receiver case.
DECIMAL POINT IS BLINKING ON FREQUENCY
• It is normal to see the decimal point blink briefly when making large
changes to frequency, as when wrapping around the band edges.
•
Can also mean the receiver is currently tuned to an invalid
frequency.
•
Otherwise, a blinking decimal point is a sign that something is
wrong with the hardware.
