Operating procedures
After unpacking the unit for the rst time, please charge the unit for about 4~5 hours before
any operation. This is absolutely necessary as the built-in rechargeable battery might have
been discharged naturally due to long shipment and storage time, even though it has been
fully charged in the factory prior to shipment.
To charge the battery, just plug in the DC end of the switch mode power supply into the DC
IN of the unit and charging will start automatically. The charging indicator LED ashes RED
during the charging process. When GREEN LED stays glowing, the battery is then fully
charged and operation could now be started.

on its panel. When the Charging / Battery Status Indicator glows RED, it means the built-in
rechargeable battery is weak and needs to be charged. While charging, the unit could also
be operated simultaneously.
