designed for use with vehicle IR rear entertainment systems. It
allows kids to enjoy their favorite movies from a DVD player
without interference, while providing a peaceful and quiet
experience for the driver. The headphones are compatible with most
vehicle rear entertainment systems that have standard infrared
sensors or IR sensors. They are powered by 2xAAA batteries (not
included) and can provide up to 20 hours of continuous working. The
headphones also feature an automatic shutdown function to prevent
battery drainage when not in use. Additionally, a 3.5mm aux jack
and aux cable are included for use with devices such as iPads,

Product Usage Instructions:
- Remove the insulator at the positive end of the battery or
insert 2xAAA batteries according to the engraved polarities in the
battery chamber of the headphone. - Turn on the headphone by pressing the ON key and switch to
either A or B channel according to the transmitter’s channel. When
the headphone is on, the power indicator will light up. - Adjust the volume to the desired level. Ensure that the
channels on both the transmitter and headphone are matched (e.g.,
if the transmitter is set to A-channel, the headphone should also
be switched to A-channel) in order to listen to the sound
transmitted from audio devices. - The headphones have an automatic power-off function. If no
transmission signal is received for approximately five minutes,
they will power off automatically. To use them again, press the OFF
key and then press ON. - To turn off the headphones, press the OFF key. If you won’t be
using them for a long time, it is recommended to remove the
batteries.

8 Kindly reminder
1. If it’s the first time for you to use our 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). Please check IR sensor frequencies of your car DVD player and make sure they are compatible with these headphones (Channel A: L/2.3MHZ, R/2.8MHZ; Channel B: L/3.2MHZ,R/3.8MHZ), or you will need to return these headphones and purchase the original ones.
2. set the volume of car DVD/TV and TV related AV devices (e.g., cable box, STB, DirecTV etc) to a sufficient level to ensure steady audio signal, or sound will be cut out.
3. If your car DVDs are universal, then please pay attention to the IR transmitting angle and distance. Sound will be cracking if too far away, or not in sight of IR transmitter, which is caused by the limitation of the IR system type, not the product itself.

SM-563B Manual
4. Some DVD manufacturers ignore the quality of built-in infrared transmitter. The poor IR transmitting modules as well as the mounting angle and quantity of infrared-ray emission tube, all of these will cause poor audio reception.
5. Please use 2XAAA decent and premium alkaline batteries. Not suggest to use rechargeable NI-MH battery. The headphone working voltage is 3.0V, the premium alkaline battery life could be at least 20 hours. But for some bad quality battery, the capacity is much less than the premium one, the using time is much shorter than expectation. For rechargeable 2XAAA NIMH batteries, the voltage is only 2.4V which will cause low volume, poor sound quality or sound cuts in and out etc. It will be reduced to 2.2V after about an hour using, and the headphones will stop working.
