The legendary King Arthur
brandished a magic sword,
Excalibur, from which we
take our company name.
With this unique weapon in
his hands, he could not be
vanquished.
Although Excalibur
Electronics can’t claim the
magical secrets of Merlin,
King Arthur’s court wizard,
sometimes our patented
technology may make it
seem as if we could.
We make you think.
Your Keychain SuDoku
game requires three LR44
batteries. To install batteries,
carefully turn it over so that
the top side is face-down on
a soft surface, such as a
towel or magazine. You’ll
find the battery compartment on the unit’s back.
Use a small Phillips screwdriver to remove the screw.
Lift off the battery
compartment lid. Install
three LR44 batteries,
making sure to match the
polarity (+ and -) with the
diagram inside the battery
compartment. Place the
tabs of the battery
compartment in their slots,
and snap the compartment
door back on. Replace the
screw and tighten it carefully.
