Power supply
The scale is normally powered by the built-in storage battery. The AC adapter is only used for charging
the storage battery. While the battery is being charged, the scale receives power from the power supply
network, so you can still work with the scale even if the battery needs recharging. Battery charging also
continues while the scale is switched off. The time required for recharging depends on how low the charge
in the battery has become. However, to avoid overcharging the battery, do not leave the scale connected
to the power supply with the AC adapter for more than 24 hours.
• Remove the 3 screws of the transport arrestment in the weighing-
pan support and the 3 plastic inserts between the weighing-pan
support and the scale housing.
• Place the weighing pan on the scale.
• Level the scale horizontally by turning the leveling screws. The air
bubble of the level indicator must lie within the black inner circle.
Battery operation (AC adapter not connected)
Observe the red LED above the battery symbol Y:
LED is not lit: The battery is sufficiently charged.
LED flashes: The charge of the battery is almost exhausted. Connect
the AC adapter as soon as possible to recharge the battery.
Charging the battery/operating from the power supply
The connecting socket for the AC adapter is located underneath the
balance adjacent to the front-left leveling screw. Remove the rubber
plug and connect the AC adapter to the scale and to the power supply.
Observe the red LED above the battery symbol d:
LED flashes: The scale is receiving power from the power supply
network, the battery is being charged.
LED is continuously lit: The battery is fully charged, the AC adapter
can be disconnected again.
