About Rechargeable Battery
Your portable TV device comes with a built-in rechargeable
Lithium-Ion battery. Charge the battery fully before initial use.
Charging time is normally about 3.5 hours. A fully charged battery
delivers about 3.5 hours of use.
When the battery is weak, an indication symbol will appear on the
LCD screen and the unit will power off automatically after a few
minutes.
Connecting to Earphones
You may connect stereo
earphones (not included) to
the headphone jack for
private listening.
When earphones are
connected, the speakers will
automatically turn off.
Caution:
Loud volume can damage your hearing.
Decrease the volume before connecting earphones, then raise the
volume back to a comfortable level.
