TROUBLE SHOOTING GUIDE 

If you encounter any trouble in setting up the Headphones, please check the following 
points:  

 

(1) Distorted sound quality or unclear sound:   

~  Check if the sound of your audio source is distorted and whether the volume control 

is tuned to the suitable level.   

~ Check if the batteries in the headphones have insufficient power. Replace fresh ones if 

necessary.  

~ Check if you have selected the best channel, Turn the Channel Tuning Knob (4)  

again to check.   

~  Check if the distance between the headphones and transmitter are within the effective 

range. (The effective range of the device is approx. 100M in open area.) Place the 
headphones closer to the transmitter. 

 

(2) No Sound from the headphones: 

~ Make sure that your audio equipment, the transmitter and headphones are properly 

connected, powered and switched ON.   

~  Check if the batteries are inserted properly into the battery compartment. 
~ Check if the transmitter is powered on with the AC/DC adaptor: the Power LED 

Indicator (11) will glow GREEN showing the transmitter is powered (only when there 
is audio signal from the audio source). 

~  Check if all the connection cords are properly connected. 
 

(3) Mono Sound: 

~  Check if the audio source is mono only, use stereo audio source.   

 

(4) Interference: 

~ At the rear side of the transmitter, there is a Channel CH1/CH2/CH3 Switch (12), 

select a different channel and adjust the Channel Tuning Knob (4) Select the Correct 
channel and The good quality sound. 

 
(5) Power auto-cut-off: 

~ The transmitter has auto-cut-off function. When there is no audio signal for a 

prolonged period, the power of the transmitter will be automatically cut off. You just 
need to switch on the audio sources again.
