If "BAT" appears in the display, the battery needs to be replaced within the
next few hours. To do so, open the battery cover at the front of the instrument.
Remove the used battery and insert a new one.
Please only use 9V monobloc (PP3) batteries.
Make sure you maintain the correct polarity when inserting the new battery
and use high-quality batteries only.
