Emerson CK5250 - Large Display Am/Fm Clock Radio Manual

INTRODUCTION

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.

For future reference, record the serial number.
Model: CK5250

IMPORTANT NOTES

• Avoid installing this unit in places exposed to direct sunlight or close to heat radiating appliances such as electric heaters, on top of other stereo equipment that radiates too much heat, places lacking ventilation or dusty areas, places subject to constant vibration and/or humid or moist areas.
• Operate controls and switches as described in the manual.
• Before turning on the power, make certain that the power cord is properly installed.
• When moving the set, be sure to first disconnect the AC power cord.

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 down this number.
• 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

• 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.

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 by trying to file the wider blade, or replacing the plug. Contact an electrician to replace your outdated outlet.

The minute will be the last digit that appeared in the time display, and the seconds will continue to advance. When the SNOOZE bar is released the display returns to the correct time.

NAP TIMER

This radio includes a programmable Nap Timer alarm. Use the Nap Timer to wake up after a nap without disturbing your regular alarm settings. The Nap Timer can be used for naps of up to 99 minutes.

To set the Nap Timer:

For example if you change the Nap Timer from 30 minutes to 45 minutes, the new default setting will become 45 minutes. The next time you press the NAP button the Nap Timer will start at 45 minutes. However if the power is interrupted and the back up battery is not installed, the Nap Timer will return to the original 30-minute default setting.
3. When the Nap Timer counts down to "00" the buzzer alarm will turn on. Press the SNOOZE button to shut off the buzzer alarm.
   Note: If you do not press the SNOOZE button to shut the buzzer off, it will continue for one hour and then shut off automatically.

The next time you press the SLEEP button the Sleep Timer will start at 45 minutes. However, if the power is interrupted and the back up battery is not installed, the Sleep Timer will return to the original 30-minute deafult setting.
3. When the Sleep Timer counts down to "00" the radio will shut off automatically.

To cancel the Sleep Timer operation and shut the radio off before the Sleep Timer counts down to "00", press the SNOOZE button at any time.

Remember that the radio station and volume settings that you choose for Sleep To Music operation are the same settings you will hear if you set the alarm for Wake To Radio the following morning.
