How to Save Battery Power
Automatic shutdown of the HT660
The HT660 will enter idle mode when there is no task, or all tasks are waiting for
input. In default setting, the HT660 will automatically turn itself off if it remains idle
for 3 minutes and when there is no external charging power applied. Pressing the
power button will return the HT660 to the same point at the time of automatic
shutdown.
Note:
Suggestion 1: Turn off wireless mode if you are not using it. This will
conserve battery power.
Suggestion 2: Disable the I/O card if Internet access is not required.
