Assembling and Changing Batteries
Possible types of batteries are 2 mono-D-cells with 1.5 Volt or 1 lithium DD 35Ah with 3.6V.
Caution
: To avoid damage, use appropriate batteries only!
To assemble the battery, remove the steel casing pipe which covers the battery compartment.
For this, twist off the ring nut and pull off the casing pipe.
Attention
: Please mind the polarity of the batteries. Inserting the battery incorrectly may blow the fuse (which can only
be repaired at the factory) or even damage the electronics.
The electronic comes with a backup capacitor which can compensate a power outage for a short time (i.e. during a battery
change), so it doesn't lose data like date and time.
If the outage was too long, the device will reboot, which is indicated by the green LED blinking about 10 times. After that
the device is ready to use. The time has to be synchronized again.
