Thank you ..........

for purchasing the world’s most accurate clock radio from Emerson Research.
The CKA1100 is designed to receive and decode the time signals transmitted from
the U.S. Atomic Clock, which is operated by the National Institute of Standards and
Technology (NIST) at Fort Collins, Colorado. This is the same time signal that is
used by the U.S. military, and agencies such as NASA, to time Shuttle launches,
space walks, etc. Whenever split second accuracy is essential the U.S government
relies on the Atomic Clock. And now you can too. The Atomic Clock is considered
accurate to within plus or minus one second per million years! This is the clock
that you will use to set every other clock in your home.

In addition to the absolute accuracy the CKA1100 also adjusts for Daylight Saving
Time and Leap Years automatically. And the month/date c alendar display also
adjusts automatically for months of less than 31 days. There are dual alarms that
can be programmed for weekdays only, weekends only, or all 7 days; a great
sounding AM/FM radio; and an extra large display for both time and month/date
that you can see from anywhere in your room.

We believe this may be the best clock radio available anywhere. We know it’s the
most accurate.

Please be sure to read this manual completely so you understand how the CKA1100
receives the Atomic Clock signal, and how to take advantage of all the other great
features we have included in this model. If you have any problems with the set-up
or operation of this model please call the Emerson Research Customer Service
Hot-Line toll free at: 800–898–9020.

Once again, thanks for purchasing the CKA1100 from Emerson Research.

The serial number of your unit is located on a label on the bottom of the cabinet.
We suggest you record the serial number in the space below in the event that it is
needed again for any reason.

PREPARATION FOR USE

AC Outlet

UNPACKING AND SET-UP

• Remove the radio and the external WWVB long wave antenna from the carton
and remove all packing materials from the radio. Please save the carton and
packing materials if possible in the unlikely event that the radio ever needs to be
returned for service. Using the original carton and packing materials is the only
way to pack the radio safely to avoid damage in transit.

• Remove any descriptive stickers or labels from the front or top of the cabinet.
Do not remove any labels from the back or bottom of the cabinet.

• Extend the AC power cord to its full length.
Note: The FM Antenna is built into the AC power cord.

• Extend the wire of the external WWVB long wave antenna to its full length.
Insert the plug from the antenna wire into the antenna jack on the back of the
radio.

POWER SOURCE

This radio is des igned to operate on normal 120V 60Hz AC power only. Do not
attempt to operate the radio on any other power source. You could cause damage
to the radio that is not covered by your warranty.

This radio should be connected to an AC outlet that is always ‘live’. Do not connect
it to an outlet that is controlled by a wall switch. When the power to the radio is
interrupted, the back up battery take over to maintain the time and alarm settings.
To maximize the life of the battery keep the radio connected to a ‘live’ AC outlet at
all times.
You will note that this system is
equipped with a polarized AC power
plug having one blade wider than the
other. This is a safety feature. If this
plug does not fit into your existing AC
outlet, do not try to defeat this safety
feature by filing the wide blade to
make it fit into your outlet. If this plug will not fit into your outlet, you probably have
an out-dated non-polarized AC outlet. You should have your outlet changed by a
qualified licensed electrician.

BATTERY BACK-UP SYSTEM

This model includes a battery back-up system that will maintain your time and
alarm settings in the event of a temporary power interruption. If power is interrupted
the display will go ‘Off’, but the batteries will continue to power the clock. When
power is restored the display will come ‘On’ again and your time and alarm settings
will be correct.

The battery back-up system requires 2 “AA” batteries, not included. We recommend
that you use a well-known brand of alkaline batteries for longest life and best
performance. The life of the batteries is affected by the frequency and length of
the power interruptions that occur in your home. For best results we recommend
changing the batteries every 12 months. There is also a “BATT. LOW” indicator on
the front panel that will warn you when the batteries are getting weak and need to
be replaced.

To install or replace the batteries:

1.) Place the radio face down. We suggest you place a towel or similar soft cloth

under the radio to avoid scratching the front lens.

2.) Remove the battery door by pressing down on the tab

as illustrated.

3.) Insert 2 “AA” alkaline batteries into the compartment

as illustrated.

4.) Replace the battery door and place the radio right

side up.

If there are no back-up batteries installed, or the back-up batteries are exhausted,
and you experience a power interruption the time and alarm settings will be lost.
Although the time will be reset automatically the next time the Atomic Clock signal
is received, the alarm times must be reset manually. We recommend that you
change the batteries as soon as you notice the BATT. LOW indicator is ‘On’, and
after changing the batteries check and adjust the alarm time settings if necessary.
