Inserting/Changing the Batteries
Alkali-manganese batteries are recommended for the laser receiver.
Turn the locking mechanism (14) of the battery compartment cover into position 
(e.g. using a coin). Open the battery compartment cover (13) and insert the batteries.
When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.
Close the battery compartment cover (13) and turn the locking mechanism (14) of the battery compartment cover into position 
.
The battery indicator (i) shows the state of charge of the batteries of the laser receiver:
Indicator | Capacity |
|---|---|
| 50 − 100% |
| 5 − 50% |
| 2 − 5% |
| 0 − 2% |
Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.
- Take the batteries out of the laser receiver when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the laser receiver.
