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 the distance between the headphones and transmitter are within the effective
range. (The effective range of the device is approx. 50M 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 keep 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.
If you still have problem after checking the above points, please contact your customer
service. Do not try to loosen the screws of the products to fix the problem.
All the above are subject to our final change without further notice.
