Battery Back-up System
This unit includes a battery back up system powered by a built-in, long life CR2430
lithium battery. The battery maintains the time and alarm settings, the Sleep and
Nap timer settings, and the preset station tuner memories as well, whenever the
power is interrupted. If the power is lost the display will go off and the system will
not operate. However once the power is restored the clock will again reset itself
and all of your other settings will be correct.
The lithium battery that was installed in your system can supply back up memory
power for up to 5 years or even longer. The actual effective life of the lithium
battery will be affected by the length of time between the date the battery was
installed at our factory and the date that you connected your unit to your AC outlet,
and by the number and duration of the power outages that you experience in your
home. To maximize the life of the back up battery this system should be connected
to an AC outlet that is always “live”. Do not connect this system to an AC outlet
controlled by a wall switch.
When the lithium battery begins to weaken, the Low Battery indicator “ ” will
begin to flash in the display. When you see this flashing indicator you should replace
the lithium battery as soon as possible. Instructions for replacing the lithium battery
will be found at the end of this Owner’s Manual.
Power Source
This system is designed to operate on 120V AC 60Hz house current only.
Connecting this system to any other power source may cause damage to the
system and such damage is not covered by your warranty.
NOTE: The system has a polarized AC plug with one wide blade and one
narrow blade. The plug will only fit into matching polarized AC outlets.
This is a safety feature to reduce the possibility
of electric shock. If the plug will not fit in your
AC outlet, you probably have an outdated non-
polarized outlet. You should have your outdated
outlet changed by a qualified, licensed
electrician. Do not file the wide blade on the
plug, or use an adapter to make the plug fit into
your outlet. This defeats the safety feature and
could expose you to electric shock.
