Safety
 It takes about 3~4 hours to fully charge the battery
when the TR-206 is powered off. If you charge the
battery in powered on status, it will take more time to
fully charge the battery.
 Please avoid storing your TR-206 in a place with extreme
temperature (hot/cold) or in a humid area. Do not leave the
device in your car under direct sunlight with closed windows.
A high temperature environment may damage the device, or
even cause battery explosion.
