Batteries should be replaced periodically based
on the battery manufacturer’s requirements to
prevent corrosion in the battery chamber.
5.1 Battery replacement
Two # 522 standard 9-volt alkaline batteries
power the Model 450. To access to the batteries,
remove the two screws at the bottom of the
handle and withdraw the battery cover plate.
The
battery bracket is attached to the cover plate and
will come out when you remove the cover. If you
have difficulty gripping the cover plate, rotate it
90
o
and then pull the battery carriage out of the
grip.
Remove the old batteries and install the new
ones in position exactly as the ones you have
removed. When replacing your batteries take
care to not damage the wires and connector.
Reinsert the battery carriage into the Mag Horn
grip and secure the cover plate with the screws.
