Operation
3. Keep the locking lever closed and turn the locking screw in anti-
clockwise direction with the 2 mm allen key until the torque
increases.
Carefully try to move the locking lever, but do not try to release it.
WARNING
Instrument mounted sideways or upside down
If the instrument is mounted in a tilted, that is non-upright way, or even
upside down, for example at a ceiling, it may drop due to an unintentional
release of the locking lever which may result in serious injury.
Precautions:
▶ Only use the GAD121 adapter plate for tilted or upside-down mounting.
▶ Make sure that the locking lever is secured by the locking screw from
unintended release by turning the locking screw in anticlockwise direction
until the locking lever is locked. If the locking lever cannot be moved, it is
secured.

Power Supply

For details regarding the charging station refer to GKL341 User Manual.

Batteries

The batteries must be charged before using them for the first time
•
because they are delivered with an energy content as low as possible.
The permissible temperature range for charging is from 0 °C to
•
+40 °C/+32 °F to +104 °F. For optimal charging, we recommend charging
the batteries at a low ambient temperature of +10 °C to +20 °C/+50 °F to
+68 °F if possible.
It is normal for the battery to become warm during charging. Using the
•
chargers recommended by Leica Geosystems, it is not possible to charge
the battery once the temperature is too high.
For new batteries or batteries that have been stored for a long time
•
(> three months), it is effectual to make only one charge/discharge cycle.
For Li-Ion batteries, a single discharging and charging cycle is sufficient.
•
We recommend carrying out the process when the battery capacity indic-
ated on the charger or on a Leica Geosystems product deviates signific-
antly from the actual battery capacity available.
The batteries can be operated from −20 °C to +55 °C/−4 °F to +131 °F.
•
Low operating temperatures reduce the capacity that can be drawn; high
•
operating temperatures reduce the service life of the battery.

Exchanging the Batteries

NOTICE
The batteries are hot-swappable. Data acquisition requires two batteries
inserted into the battery compartment. The instrument does not shut down
when only one battery is inserted.
