6.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage.
Only use original KERN mains adapters. Using other makes requires consent by
KERN.
6.4 Battery power supply
The balance is fitted with rechargeable NiMH R6 (AA) batteries and plug-in power
pack as standard.
Use the provided power pack for battery charging.
During initial operation it is very important to charge the batteries for c. 12 hours.
Afterwards discharge the batteries completely 3 times (watch display message and
automatic disconnection) and recharge. If this is done, the life of the batteries will be
increased and the nominal capacity of the batteries reached.
For operation with rechargeable batteries the balance has some functions which can
be activated or deactivated in the menu; see Section 12.4.
If the AUTO-OFF function is activated, the balance switches off automatically to save
the rechargeable batteries after 5 minutes without load change.
If the symbol or “bat lo" appears in the display when switching on the balance, this
means that the capacity of the rechargeable batteries will soon be exhausted, charge
the rechargeable batteries as soon as possible.
This symbol will pop up every 2 seconds during the charging process.

6.5 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.
6.6 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1).
During this warming up time the balance must be connected to the power supply
(mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
