Troubleshooting

IRR-1
The receiver has no power

•  Make sure the receiver is fully charged. Verify that the 3.5mm plug is inserted properly 

into the headphone jack and the ON LED is illuminated. Note: IRR-1 receiver is 

equipped with a rechargeable, non-removable Li-Polymer battery. In case of battery 

failure do not attempt to replace or repair it. Please contact your local distributor for 

further instructions.

No audio or poor audio quality (distortion)

•  Check the volume control setting. Make sure the receiver is kept in the line of sight and 

range of the transmitter/emitter and that the 3.5mm plug is property inserted into the 

headphone jack.

•  Check the transmitter operation and make sure that the transmitter and receiver are 

operating at the same channel/frequency. If Neck Loop is connected verify that the 

Stereo channel transmission is selected.

•  Check the Squelch setting – if enabled, the audio output will be muted whenever the 

signal from the transmitter/emitter is off or the level is too low.

The Installation Guide is based on the information available at the time of printing and are 

subject to change without notice.
