Thank you for purchasing this Emerson Large Display AM/FM Clock Radio  
with Dual Alarms and NAP Timer.  
The extra large LED display is designed to be highly visible and easily readable  
from anywhere in your room. At the same time we have managed to minimize the  
cabinet size so that the radio won’t take up too much space on your night table.  
The dual alarms can be set and used independently. And since there are two  
separate Radio/Buzzer selector switches, you can set one alarm to wake you to  
buzzer and the other to wake you to radio if your wish. All of the controls are easy  
to see and easy to use. The radio has a slide rule dial for easy tuning. The clock has  
forward and reverse setting controls for quick and easy adjustments.  
The Sure-Alarm battery back up system will remember the time and alarm settings  
of course, but it can do more than that. As long as there is a fresh 9-volt battery  
installed, the Sure-Alarm system will operate the radio or buzzer alarm to wake  
you up even if the power is off at your normal wake up time.  
We have taken great care to make sure that your radio was in perfect working  
order when it left our factory. It has been designed to give you many years of  
enjoyment and trouble free operation. Should you experience any problems with  
the operation or performance of this product please refer to the service and warranty  
information at the end of this instruction manual.  
Once again, from all of us at Emerson Radio Corp., thanks for your purchase.  
For future reference, record the serial number in the space provided.

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 2 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.  
SURE-ALARM BATTERY BACK UP SYSTEM  
The Sure-Alarm battery back up system in this radio will maintain the time and  
alarm settings in the event of a temporary power interruption. When the power is  
restored the time and alarm settings will be correct. If the power is off at your wake  
up time, the Sure-Alarm system will use the battery power to turn on the radio or  
buzzer alarm as usual, as long as the back up battery is installed and has sufficient  
power remaining.  
The Sure-Alarm battery back up system requires one 9-volt battery, not included.  
We recommend that you install an alkaline battery for longest life and best  
performance.

TO INSTALL THE BATTERY  
Press  
Open the battery compartment cover on the bottom  
of the radio by pressing the tab in the direction of  
the arrow.  
Connect the 9-volt battery to the battery terminal. It  
can only be connected one way.  
Push the battery into the battery compartment and  
replace the cover.  
POWER FAILURE INDICATOR  
If no battery is installed in the radio, or if the battery in the compartment is weak or  
dead, the time and alarm settings will be lost if the power is interrupted. When the  
power is restored the clock display will begin flashing. This is your indication that  
the time display is incorrect and needs to be reset.  
Important:  
After you reset the time, be sure to reset your alarm settings as well.  
POWER SOURCE  
This radio is designed 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 Sure Alarm battery back up system takes over to maintain the time  
and alarm settings. To maximize the life of the back up battery, keep the radio  
connected to a ‘live’ AC outlet at all times.  
This radio uses a polarized AC plug which  
has one blade wider than the other. This  
plug will only fit into a polarized AC outlet.  
This is a safety feature. If the plug will not  
fit, you may have an older non-polarized  
AC outlet. Do not defeat the safety feature  
AC Outlet  
AC Plug  
by trying to file the wider blade, or replacing  
the plug. Contact an electrician to replace  
your outdated outlet.
