Remove any used batteries.

Insert two new batteries (type AAA, LR 03, AM 4 or micro). The

minus (-) ends of the batteries must match up with the minus marks
in the battery compartment.
Re-attach the battery compartment cover. The three hooks under-

neath the cover must engage with the slots along the edge of the
battery compartment. The cover is then just loosely held in position.
Slide the battery compartment cover back in place. There will be an

audible CLICK as it closes.

Initial steps before testing
When you replace the batteries, your results always remain
i
saved.
The year, time and date settings, however, only remain saved as long as

you don't take longer than two minutes to change the batteries,

you don't press any button while no batteries are inserted,

you don't open or close the drum compartment while no batteries
are inserted.
If one of the above conditions is not met, you will need to re-enter the
year, time and date (see Chapter 3 "Settings").
If you do not enter the year, time and date, all future results will be dis-
played and saved without the time and date. In that case the test results
saved in memory will be numbered consecutively so you can still recog-
nize the order in which they were saved.
A new pair of batteries has enough power for at least 1000 tests
i
or to last one year. If you use the meter in Acoustic Mode, they
will not last as long.
