(2). Power on the headphones
Press on to turn on the headphones, then
select to Channel A or Channel B, make
sure the headphones’ channel is same as
the relative transmitter’s/ DVD’s, otherwise
will cause intermittent sound issues.
Note:
* If it's the first time to use SIMOLIO universal IR headphones and experience
no sound, audio cuts, only hear sound by one side, most are caused by car
DVD's frequencies deviation (non-universal), then you will need to return
these headphones and purchase the original ones.

* For two kids in the same row and are watching different movies on two DVD

* If the headphones have been powered off automatically, please turn off it
first, then press ON to turn on the headphones.
4. How to Adjust the Headband to Fit Better
* Please pay attention to the IR transmitting
angel & distance, the best audio signal will
be obtained if you sit directly in front of the
monitor within 6 feet. If you sit on either
side of the monitor you can expect the
same great reception within 35 degrees to
the left or the right of the monitor. Sound
will be cracking if sit too far away, or not in
sight of IR transmitter, which is limitation of
the IR system type, not the product itself.
(Ref. Fig 3)
* Please turn off the headphones and take out the batteries before storage.
Please make sure the headphones are being worn properly.
