Calibrating the touchscreen
To ensure precise and reliable operation of touchscreen control, you can open
the "Calibrate touchscreen" menu.
The device then prompts you tap 4 points on the touchscreen.
Simply follow the instructions on the display.
CAUTION!
A backup battery is built into the device. Its purpose is to maintain data when
the device is switched off or if the voltage supply is interrupted. If the battery
approaches the end of its operating life (approximately 7 years) then a battery
prealarm will indicate that status. When the battery is empty a battery alarm will
indicate that status. The battery must be exchanged before it is empty. The bat-
tery must be exchanged by the JUMO Service department! In this case, send
in the device!
