1 General Information
1.1 Unpacking and Inventorying
When you first unpack your BA28, take a quick inventory to make sure
the package comes complete with all the contents. A power supply
unit, two battery packs are included.
1.2 Powering Up
With the External Power Supply Unit
First connect the external power supply unit to the DC In socket 20 on
the rear panel of the BA28, and then connect the power cord to a power
outlet.
For the First Time with Battery Packs
Remark: Make sure to charge both battery packs fully before using for
the first time.
Unfasten the wing screw on the rear battery compartment by turning
it counterclockwise. Remove the cover. Slide the two included battery
packs into the compartment until you feel them click firmly into place.
Put the battery compartment cover back and fasten the wing screw by
turning it clockwise.
The two batteries will start charging successively as soon as you
connect BA28 to a power supply. The battery in slot A is charged first;
the battery in slot B comes second. (Refer to section 3 - Operating
BA28 on Battery Power, for more information.)
BA28 immediately switches over to battery-operated mode when the
power supply unit is disconnected. One of the two control LEDs on
the battery compartment will flash slowly to indicate which battery
is currently in use. BA28 switches over to another battery pack
seamlessly (hot-swappable).
Remarks: Charging the battery packs in BA28 takes up to 5 hours,
which is shortened to 2 hours with external fast charger (sold
separately)
