Panasonic RC6099 - Operation

Operation
The sure time
battery back-up
is
designed
to hold the present time and the alarm
time
in
the
memory
in the
event
of
a power
failure or
interruption.
(Such
as
when
moving
this
unit
to
a different
room.)
Whenever
a power
interruption
occurs,
the
digits on the
clock display
will
disappear.
However, even
though the
clocl^
face
is
completely
blacked out,
the
9-volt
back-up
battery
will take
over
as
the
power
source
and the present
time and
the
alarm
time
will
be presen/ed.
Even
if the
power is
not resumed by the
wake-up
time,
the buzzer
alarm
will acti-
vate.
Notes
When the
set
is
unplugged
(not
in
use) for
a long time,
remove the
back-up
battery
to
prevent
possible battery
leakage.
Power failures
may
occur
at any
time of
the
night
or
day
and
can
be of a
long
or short
duration.
Most failures
are
so
short that
people
don't
even notice
the interruption. These inter-
ruptions
do,
however,
affect
clocks
which
do not
incorporate
a
battery back-up.
If
the power is
not
resumed
by
the
wake-up
time, the radio
alanm
will not
activate.
If
the
back-up battery
goes dead
during
a
power
interruption,
the
present
time and
alarm
time must also
be reset after the
intemjption.
The
back-up
battery
will
be exhausted
after
about 1
4
hours of
total (accumulative)
use,
(The battery
life
will
vary depending
on
the
frequency
of
the
power interrup-
tion.)
After
a power
interruption,
the
time
shown
in
the
display window
may
not
be always
conrect
(It may gain
or lose
about
six
minutes
per hour).
