Operation using a rechargeable battery (optional)

Take off the weighing plate and remove the bracket by loosening the screw. Use a
screwdriver to loosen both screws to the left and right of the bracket guide and re-
move.
Release both retaining hooks on the lower housing section and carefully remove the
lower housing section to the rear (please observe the upper housing section guides
on the back of the balance).
Loosen and remove both fastening screws as shown on the illustration.
Remove the rechargeable battery from the packaging and begin by connecting the
electric power supply to the circuit board of the rechargeable battery.
Subsequently set up the plug-in connection to the computer circuit board of the bal-
ance (CN5).
The rechargeable battery is placed on the left side of the housing in such a way that
it can be screwed onto the balance through the existing mounting using the screw
loosened previously. Press lightly into the housing prior to this, (there is only one cor-
rect installation possibility). Now also re-attach the display using the loosened screw.
Place the upper housing section on the rear guides and tilt forward until both retain-
ing hooks on the lower housing section audibly lock into place.
Screw down both screws to the left and right of the bracket guide tightly and re-
secure the bracket. Attach the weighing plate.
Information:
Though the rechargeable battery is immediately operative, it should be charged for at
least 8 hours using the mains adaptor before being used for the first time.
