tips
If
the

is
not
holding
charge
or
the
charging
indicator
does
not
turn
on,
open
the
battery
compartment
and
make
sure
the

is
properly
connected.
If
the

are
securely
connected,
check
the
fuse
on
the
back
panel.
If
the
fuse
is
blown,
replace
it.
Please
heed
the
warning
label
on
the
bottom
of
the
fuse
holder
and
rear
panel.
If
the
battery
charging
indicator
still
does
not
turn
on,
check
the
