5. BATTERY REPLACEMENT
Battery replacement display
Depending on use of the device the battery lasts from a couple of months up to one
year (please note chapter 2 “Putting into operation”). To avoid a sudden and
unpleasant interruption of operation a battery symbol will appear, above the date
symbol, as soon as the battery becomes too weak and needs to be replaced.
To replace the batteries please follow the instructions in chapter 3.7 (Battery
compartment).
If the battery is replaced in one minute’s time, certain information will remain stored:
– Alarm setting
– Compass calibration
– Data Logs
– Display units
The other settings are lost and must be re-set.
Please remember that used batteries do not belong in normal household trashcans,
they should be collected and disposed of at the appropriate collection sites. The
environment appreciates it!
