soon as possible:
1. Remove the two (2) Phillips screws from the rear of the meter (directly above the top of the tilt
stand).
2. Remove and safely place the battery compartment and screws where they will not be damaged
or lost.
3. Replace the six (6) 1.5V ‘AA’ batteries, observing polarity.
4. Replace the battery compartment cover with the two (2) Phillips screws.
All EU users are legally bound by the battery ordinance to return all used batteries to
