Important Maintenance Guideline
After unpacking the unit for the first time, please charge the unit for about 8 hours. This is absolutely necessary as the built-in
rechargeable battery might have been discharged naturally due to long transportation and storage time, even though it has
been fully charged in the factory prior to shipment. For maximum battery life please follow this important procedure.
• Charge BEFORE you start using for the fist time
Ensure battery is fully charged BEFORE you store the unit. To preserve a longer battery life and better performance, make
sure you recharge the battery monthly.
When you need to use the unit again after a long period of storage, make sure you charge it fully for at least 8 hours BEFORE
using any operations.
Please also charge this unit every time right after operation to secure a longer battery life.
• Charge fully
• This unit has DOD (depth of discharge) protection design. When Power Switch LED flashes red it means there isn’t enough
battery power. This unit will turn off automatically in order to prevent deep-discharging damage. When battery power is low,
please immediately recharge your unit. Do not continue with operation.
• This unit has protection circuit against overcharge. The circuit will stop charging when battery is fully charged, even when
the power cord is plugged into the mains power socket.
Useful hint: You can still operate during charging.
• Battery Replacement
We recommend Altronics S 5078 for optimum compatibility.
