The battery level indicator shows the battery status in
four steps.
If the three bars on the display are blank and the outside
frame flashes, the battery is flat and you must charge it.
If you do not notice this, the device switches off
automatically after a certain amount of time.
During charging the three bars flash from top to bottom.
When the battery is fully charged, all the bars are shown.
Charge the battery at room temperature using only the
THEIS standard mains unit connected to the charger
socket below the laser. Charging at temperatures below
+5°C can lead to defects in the battery.
Charging is also possible during operation. Overloading
is not possible.
Only use the charger on dry premises!
The batteries that are used with Eneloop™
technology have the advantage of low levels of self-
discharge. This means that if you do not use the
device, you only need to recharge it every six
months.
In the battery compartment, you can also use
normal alkaline mono-cells. Under no
circumstances must you recharge them. If you
do this by mistake, the battery symbol flashes.
Important: Observe the correct polarity.
There are ±symbols on the base of the
battery compartment. Observe the
disposal information in point 18.
Important: Because the battery poles
and contacts may soil over time, resulting
in contact problems, regular inspection
and possibly cleaning with a soft cloth
and cleaning agent (spirit, alcohol) are
necessary.
