CHANGING THE LITHIUM BATTERY
Like all batteries, eventually the built in lithium battery will need to be replaced. A
number of factors, such as, the length of time between the date the clock was
manufactured and the date you plugged it in for the first time determine the amount
of time before replacement. During this initial storage period, the lithium battery is
supplying power to the SmartSet
®
computer memory. Once you plug the clock in,
your household outlet supplies the power, and the battery is not being used. A
fresh lithium battery can supply power to the SmartSet
®
computer for at least 3
years even if it is never connected to an AC power supply. If your clock was
connected to your AC supply within a few months after it was manufactured, and
you experience only the normal, nuisance type, short duration power interruptions,
your battery may last for up to 5 years or even longer.
When the battery power drops below a certain level, the LOW BATT. indicator will
‘flash’. When you see this indicator, you should change the battery as soon as it is
convenient for you to do so. To change the battery proceed as follows:
1.) Purchase a replacement 3V lithium battery wherever batteries are sold. The
battery type is CR2430 or equivalent.
2.) Remove the battery from its package so it is ready to install.
IMPORTANT: Leave the clock power cord connected to your AC outlet.
This will provide power to the SmartSet
®
computer memory while the
original lithium battery is removed.
3.) Turn the clock up side down and use a small screwdriver to remove the two
screws securing the battery cover to the cabinet.
BE CAREFUL NOT TO LOSE THESE SMALL SCREWS!!
4.) Remove the battery cover. Then remove the original battery and insert the
new battery into the holder the same way, with the negative (–) side facing up.
5.) Replace the battery cover and re-install
the two screws.
6.) Turn the clock right side up and confirm
that the LOW BATT. indicator is ‘Off’.
7.) Save these instructions. You’ll have to
do this again five to eight years from
now!
