Recharge the 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.
If the charging indicator LED
glows RED, the battery power might be too low and recharging
is necessary. 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. During the charging process,
the charging indicator LED
will flash GREEN. When this LED glows steady GREEN, this
battery is then fully charged.
