the test results saved in memory will be numbered consecutively
so you can still recognize the order in which they were saved
(see Chapter 5.2).
If the year, time and date have been lost, the meter rotates the
drum in order to re-read the bar code.
You can also use rechargeable NiMH batteries. If you do, please

note the following:
The number of tests you can perform with recharged batteries is
considerably less than with ordinary batteries.
To be ready to test at any time, you need to keep two rechargeable
batteries in reserve which you can charge while the first pair are in
the meter.
Recharged batteries lose their charge during storage.
When the battery symbol first appears, you can perform significantly
fewer than 50 further tests. With old and exhausted rechargeable
batteries you may not be able to perform even one more test.
The performance and useful life of rechargeable batteries depends
to a large extent on the quality of the battery charger you are using.
Owing to the higher power consumption, we advise against using
rechargeable batteries if the brightness of the display is set to level
3 (high) or if Acoustic Mode is set to on.

Think of the environment. Dispose of used batteries sensibly.
