Putting the Meter into Operation
18
Power Supply
The meter can be operated with either the handheld power supply provided, the (optional) Hand-
held Base Unit or the (optional) handheld battery pack. It is advisable to insert the handheld bat-
tery pack even when you use the handheld power supply. This ensures that you do not lose the
date and time settings (in case of a power outage or if the local power supply is shut off). Results
are retained in the memory together with the corresponding date and time, as well as all other
settings, even when no handheld battery pack is inserted.
To save power, the meter can automatically turn itself off after a programmable period of time, if
no buttons are pressed or new test strips are inserted. When the meter turns itself off, all test
results obtained up to that point remain in memory and the settings are retained (see “Auto Off”
in the chapter entitled “Data Handling Setup” on page 42).
During battery operation, the meter always
displays the power level of the handheld
battery pack. The battery icon is divided into
four segments which correspond to the bat-
tery power level.
Note: When replacing the batteries you must
insert the new handheld battery pack within
ten (10) minutes of removing the old one, to
retain the date and time settings. If you take
longer than this, you must re-enter the date
and time.
To make certain you do not lose your date and
time settings, connect the handheld power
supply unit while you change the handheld
battery pack.
Note: Dispose of used battery packs in an environmentally responsible manner in accord-
ance with applicable local regulations and directives.
