Recharge its inbuilt Lithium battery before first use
After unpacking the unit for the first time, please recharge the unit for about 4~5 hours before
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 had 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
⑫of the unit and charging will start automatically. During the charging process, the charging
indicator LED ⑪will be RED. When this LED turns GREEN, this battery is then fully charged.
