Battery Charge Indicator

The battery charge indicator (3) shows the current state of charge of the lithium-ion battery pack/non-rechargeable batteries when the measuring tool is switched on.

If the lithium-ion battery pack or non-rechargeable batteries are running low, the laser lines will gradually become dimmer.

If the lithium-ion battery pack/non-rechargeable batteries are almost empty, the battery charge indicator (3) will flash continuously. The laser lines will flash for 5 seconds every 5 minutes.

If the lithium-ion battery pack/non-rechargeable batteries are empty, the laser lines and the battery charge indicator (3) will flash one last time before the measuring tool switches off.
