Note:
Always turn on the battery switch before starting the freezer. The freezer will enter
normal working state and charge the battery upon connecting to an AC power supply
meeting its requirements. In case of AC power failure, the battery will energize the
display screen for normal display. When the voltage of battery reduces to less than a
specified value due to discharge, it will stop energizing the display screen and thus
the display screen will not display any longer. When the battery is able to supply
electricity normally, to completely cut off the freezer’s power supply, just pull out its
AC power cord and turn off its battery switch. Then the display screen will not
display any longer.
