Power supply
The meter can be operated with the rechargeable battery pack only or together with the power
adapter or the (optional) Handheld Base Unit, which both charge the battery pack when inserted.
Insert the battery pack even when always using the power adapter or the Handheld Base Unit.
This ensures that you will not lose the date and time settings if the power goes out. Results are
retained in the memory together with the corresponding date and time, as well as all other set-
tings, even when no battery pack is inserted.
In general, it is not recommended to detach the external power supply or undock the meter from
the Handheld Base Unit during a measurement. When the meter is connected to an external
power supply and the battery level is low, measurements cannot be completed if the external
power supply is detached. In this case a message is displayed not to remove the external power
supply.
To save power, the meter can automatically power itself off or go into standby mode, if no
buttons are pressed or new test strips are inserted. When the meter powers 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 62).
