5.4 Rechargeable battery operation (option)
The internal battery is charged with the supplied mains cable.
Before the first use, the rechargeable battery should be charged by connecting it to
the mains power cable for at least 15 hours. The operating time of the battery is
about. 70h. Charging time until complete recharging ca. 12h.
To save battery life, the background light can be switched off in the menu
(See chap.. 11 menu).
An arrow  appearing on the weight display below the battery icon indicates
that the capacity of the rechargeable battery is low. The balance will be ready to
operate for about another 10 hrs., then it will switch off automatically. Connect the
power cable as soon as possible to load the rechargeable battery.
5.5 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.
5.6 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.
