Replacing the Batteries
The device is already equipped with a built-in 9 V alkaline battery of the type 6F22 when being
delivered. As soon as the Low-Bat indication appears on the display, please replace the battery
because otherwise, the precision of the indication is no longer guaranteed. To replace the battery,
proceed as follows:
Remove the battery cover on the back of the device by pushing carefully.
|
Remove the empty battery and replace it by a new one of the same type.
|
| Ensure correct and secure position of the battery.
Put the battery cover back onto the device and close the device by pushing carefully back.

The user is legally obliged (old battery regulation) to return all used batteries (from round cells to
lead storage batteries) to a specialist dealer's shop where there are special facilities (collecting
boxes). It is forbidden to dispose of batteries in the garbage bin or litter.
