To change the batteries, open the battery compartment by pulling it out like
a drawer. To maintain child safety, quite a lot of strength is required. Always
remove all three batteries and replace them with new batteries of type CR
1225.
Observe polarity! The positive pole of all three batteries must point upwards.
Incorrectly inserted batteries may damage the device. Once all three batteries
are correctly inserted, push the battery compartment back in completely.
Then check the function of the ESYSTA
®
BT Pen by venting as described in
Chapter 6.7.
Note:
We advise changing the batteries near your smartphone with the ESYSTA
®
App and with Bluetooth
®
transfer switched on and then importing the data,
so that your ESYSTA
®
BT Pens can be optimally time-synchronised with the
ESYSTA
®
App.
