FCC INFORMATION  
This equipment has been tested and found to comply with the limits for a Class B  
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to  
provide reasonable protection against harmful interference in a residential  
installation. This equipment generates, uses, and can radiate radio frequency  
energy and, if not installed and used in accordance with the instructions, may  
cause harmful interference to radio communications. However, there is no  
guarantee that interference will not occur in a particular installation. If this

PREPARATION FOR USE  
UNPACKING AND SET UP  
Remove the radio from the carton and remove all packing material from the  
radio. We suggest that you save the packing material, if possible, in the unlikely  
event that your radio ever needs to be returned for service. The original carton  
and packing material is the only safe way to pack your radio to protect it from  
damage in transit.  
Remove any descriptive labels or stickers on the front or top of the cabinet. Do  
not remove any labels or stickers from the back or bottom of the cabinet.  
Note the serial number on the bottom of your radio and write this number in the  
space provided on Page 1 of this manual.  
Place your radio on a level surface such as a table, desk or shelf, convenient to  
an AC outlet, out of direct sunlight, and away from sources of excess heat, dirt,  
dust, moisture, humidity, or vibration.  
Unwind the AC power cord and extend it to its full length. The FM antenna is  
built in to this cord. It must be fully extended to provide the best FM reception.  
POWER SOURCE  
This radio is designed to operate on normal 110V-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 built in lithium battery takes over to maintain the time and alarm  
settings. To maximize the life of the lithium 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.

OPERATING INSTRUCTIONS  
SETTING THE TIME, THE FIRST TIME  
Important: The first time you connect your new SmartSet® clock radio to the AC  
outlet the internal computer will automatically set the time correctly for the Eastern  
Time Zone, which is the initial default setting. The display will scan for a few seconds  
and then show the correct month, date, day and time in the Eastern zone. If you live  
in the Eastern Time zone, there’s nothing else to do. Your clock is set correctly and  
running.  
If you do not live in the Eastern Time zone you must change the default zone  
display to your own zone. You only do this one time and the SmartSet® will  
remember the new default zone setting and will always return to that setting after  
a power interruption  
There are 7 time zones programmed into your SmartSet® clock radio as follows:  
Zone 1  
Zone 2  
Zone 3  
Zone 4  
Zone 5  
Zone 6  
Zone 7  
Atlantic Time  
Eastern Time  
Central Time  
Mountain Time  
Pacific Time  
Yukon Time  
Hawaiian Time  
To change the default time zone display, depress the Time Zone button. The number  
“2” will appear on the display indicating that the default zone is Zone 2, Eastern  
Time. Hold the Time Zone button and then press either the Up or Down buttons  
until your own time zone appears on the display, then release the buttons. The  
clock display will change to the correct time in the time zone you selected. The  
clock will always return to the correct time in the zone you selected after every  
power interruption. If you move to a different time zone, simply change the default  
zone display to the new zone and the SmartSet® will remember that setting for  
you.  
DATE DISPLAY  
To see the correct date at any time, depress the Date button. The display changes  
from time to month and date (MM/DD). For example, May 21st will appear as  
“5 21”. When you release the Date button the display returns to the correct time.  
5
YEAR DISPLAY  
To see the correct year, depress the Time and Date buttons together. The display  
changes from time to year. When you release the Time and Date buttons the  
display returns to the correct time.  
DAYLIGHT SAVING AND LEAP YEAR ADJUSTMENTS  
All Daylight Saving and Leap Year adjustments are made automatically  
by the SmartSet® internal computer as follows:  
Start of Daylight Saving Time: At 1:59.59 AM on the first Sunday in  
April, the clock will automatically advance to 3:00 AM.  
End of Daylight Saving Time: At 2:59.59 AM on the last Sunday in  
October, the clock will automatically reset to 2:00 AM.  
Leap Year: At 12 Midnight on February 28th, the calendar display will  
change to "2. 29"  
MANUAL TIME ADJUSTMENTS  
Some people like to set their clocks 5 to 10 minutes fast to make sure that they  
will always be on time. Even though the SmartSet® sets the time by itself, you still  
have the option of adjusting the time manually if you wish.  
To manually adjust the time display depress and hold the Time button, and press  
either the Up or Down buttons to adjust the time display ahead or back as desired.  
Each press of the Up or Down buttons will change the display by one minute. If  
you hold the Up or Down buttons the display will continue to change. The display  
will change slowly at first, one minute at a time. But if you continue holding the Up  
or Down buttons the display will change rapidly.  
Note: If you manually adjust the time, your new setting is entered into the  
SmartSet® memory. If the power is interrupted, the display will return to  
your new setting, not the original setting, when the power is restored.  
ADJUSTING THE WAKE UP TIMES  
Your SmartSet® clock radio has two separate alarms that can be set and used  
independently. You may use the alarms to wake two people at different times, or  
you may use one alarm for weekdays and the other for weekend wake up times.  
The procedure for adjusting the wake up time is the same for both Alarm 1 and  
Alarm 2.  
6
1. Depress and hold either the Alarm 1 or Alarm 2 setting button. The display will  
change from the correct time to the Alarm 1 or Alarm 2 wake up time.  
2. While holding the Alarm 1 or Alarm 2 setting button, depress either the Up or  
Down button to move the display ahead or back to your desired wake up time.  
3. When the desired wake up time appears on the display, release the Up or  
Down buttons.  
Note: Be sure that you have set the wake up time correctly by observing the AM  
indicator. If the AM indicator is ‘On’ the wake up time is “AM”. If the AM indicator  
is ‘Off’, the wake up time is “PM”.  
4. When the desired wake up time (AM or PM) appears on the display, release  
the Alarm 1 or Alarm 2 setting buttons.  
SELECTING THE ALARM MODE  
Your SmartSet® clock radio allows you to select from among three different alarm  
operation modes for either alarm. The alarm modes are:  
• Weekdays only – the alarm will only turn on Monday through Friday;  
• Weekends only – the alarm will only turn on Saturday and Sunday;  
• Everyday – the alarm will turn on all 7 days.  
To check the Alarm Mode setting for Alarm 1, depress the Alarm 1 setting button.  
The display will show the Alarm 1 wake up time and the day of the week indicators  
will show you the alarm mode which is selected. If all 7 indicators are ‘On’, the  
Everyday mode is selected. If only the Monday through Friday indicators are ‘On’,  
the Weekdays only mode is selected. If only the Saturday and Sunday indicators  
are ‘On’, the Weekends only mode is selected.  
To change the Alarm Mode setting for Alarm 1, hold the Alarm 1 setting button and  
press the Alarm Mode button until the day indicators show the desired mode setting,  
Weekdays only, Weekends only, or Everyday operation. Release the Alarm Mode  
and Alarm 1 setting buttons and the display will return to the correct time.  
CHECKING THE WAKE UP TIMES AND ALARM MODE  
Whenever you want to check the wake up time or the alarm mode settings, simply  
press either the Alarm 1 or Alarm 2 setting buttons. The display will change from  
correct time to wake up time and the day indicators will show you the alarm mode  
which is currently selected.  
Release the Alarm 1 or Alarm 2 setting buttons to return to correct time.

and count down to zero from that point.  
3. To cancel the sleep timer before it counts down to “00” and shut the radio ‘Off’  
immediately, press the Snooze Bar.  
IMPORTANT: Remember that the station and volume settings you choose for the  
Sleep To Music operation are the same settings you will hear if you set the alarm  
for wake to radio the following morning.  
DIMMER CONTROL  
The Dimmer control was set to the ‘High’ position at our factory. If you find the clock  
display is too bright in a darkened room, set the Dimmer control to the ‘Low’  
position.  
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 radio 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 radio 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  
radio 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 Battery indicator will  
come on. 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:  
10  
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.  
3. Important: Leave the radio power cord connected to your AC outlet. This will  
provide power to the SmartSet® computer memory while the original lithium  
battery is removed.  
4. Turn the radio upside down and use a small screwdriver to remove the screw  
securing the battery holder to the cabinet.  
BE CAREFUL NOT TO LOSE THIS SMALL SCREW!  
5. Turn the radio right side up and remove the battery holder. Then remove the  
original battery from the holder and insert the new battery into the holder the  
same way, with the positive (+) side facing up. Slide the holder with the new  
battery back into the opening in the cabinet.  
6. Turn the radio upside down again and replace the screw that secures the  
battery holder in the cabinet.  
7. Turn the radio right side up and confirm that the Low Battery indicator is ‘Off’.  
8. Save these instructions. You’ll have to do this again five to eight years from  
now!  
11  
RESETTING THE CLOCK AFTER A TOTAL MEMORY LOSS  
If you do not change the built in lithium battery within a reasonable period of time  
after you see the low battery warning indicator, the lithium battery may become  
exhausted and will no longer be able to supply back up power to the SmartSet®  
internal computer. If the unit is disconnected from the AC outlet after the battery is  
exhausted, or if a power interruption occurs, the SmartSet® memory will be lost and  
the clock will need to be reset when the power is restored. Be sure to install a fresh  
lithium battery before you reset the clock, otherwise the clock will need to be reset  
each time the power is interrupted.  
If the lithium battery is exhausted and you experience an interruption in the AC  
power supply, the clock will reset itself to its initial default setting when the power is  
restored. The initial default setting is 6:00 AM, Thursday, January 1st (1 1), 1998. If  
you notice that the time on your SmartSet® clock radio is completely incorrect, and  
the day indicator is also wrong, press the Time and Date buttons together to see the  
year. If the year display is showing “1998” you probably experienced a total memory  
loss. To reset the clock after a total memory loss, proceed as follows:  
1. Follow the instructions on page 10 and install a new CR2430 lithium battery in  
the battery compartment.  
2. Connect the radio to your AC outlet and let the clock set itself.  
3. Depress the Time and Date buttons together. The display will change from  
‘time’ to ‘year’.  
4. While holding the Time and Date buttons, press the Up button to set the display  
to the correct year, then release the buttons.  
5. Depress the Date button. The display will change from ‘time’ to ‘month/date’  
(mm/dd).  
6. While holding the Date button, press the Up button to set the display to the  
correct month and date. The Day indicator will change automatically as you  
adjust the month/date settings. When the correct month and date appear on  
the display, release the buttons.  
7. Depress the Time button and the Up button to set the display to the correct  
time. Be sure to confirm that you have set the time correctly to ‘AM’ or ‘PM’ by  
observing the AM indicator.  
8. After you set the time, reconfirm that the Day, and Month/Date displays are  
still correct. Make final adjustments if necessary.  
12  
The SmartSet® clock memory is now reset and the new lithium battery will maintain  
it for the next 5 to 8 years, depending on the number and duration of the power  
outages you experience.  
IMPORTANT NOTE:  
After resetting the clock, don’t forget to reset your wake up times, and alarm  
mode settings, and sleep timer settings as well.  
CARE AND MAINTENANCE  
If the cabinet becomes dusty, wipe it with a soft cloth. If the cabinet  
becomes smudged or dirty, clean it with a soft, slightly dampened cloth.  
Never allow water or any liquid to get inside the cabinet. Never use any  
abrasive cleaners or cleaning pads as these will damage the finish of  
your radio.
