lights
display
the
status
of

back
of
the
DS4500

a
few
minutes
after
you
turn
on
the
power.

might
blink
intermittently.

completes
its

up
before
checking
for

It
can
take
up
to
15
minutes
for
the

to
complete
its
self-test
and
up
to
24
hours
to
fully
charge,
particularly
after
an
unexpected
power
loss
of
more
than
a
few
minutes.
