Troubleshooting
“POWER” LED does not
light on transmitter
Ensure power adapter is connected to mains and working properly
Ensure POWER button is switched on
Bodypack is powered up
but no RF indication
Ensure that the transmitter is switched on
Check that the transmitter is not out of reception range
Check that the receiver is on the same channel as the transmitter
RF signal is OK but no
sound from headphones
Check that the audio input into the transmitter is OK and connected properly
Check that the input level control on the transmitter is not turned fully down
Check that the bodypack volume control is not turned fully down
For wired headphones, check the dedicated headphones volume control
RF carrier signals are
"dropping out"
intermittently
Avoid any physical barriers (e.g. walls) between transmitters and receiver
Adjust the angle of the antenna to try to achieve more stable reception
Make sure the transmitter power (POW) is set to high (H)
Try a different UHF channel
Headphone output is
very loud or distorted
Turn down VOLUME on the bodypack receiver
For wired headphones, turn down the dedicated headphones volume control
Turn down the input level on the transmitter unit
Slide the PAD switch to -12dB for high level input signals
