Question about RCA RP3721 Clock Radio
I have lost my manual for this alarm clock. Unfortunately the power went off and it doesn't remember the wake radio station presets and I don't remember how to reset them. Any help would be much appreciated. John

Sure Alarm battery Back-Up System
This SmartSet® Clock Radio includes a Sure Alarm battery back-up circuit that can
wake you up even if the power is 'Off'at the selected wake up time. If your power
is 'Off'at the selected wake up time the clock display will be off and the radio will
not operate, but a separate mini-buzzer will turn 'On'automatically to wake you up,
even if you had selected the "Wake to Radio"option.
The Sure Alarm will sound for 30 seconds and then shut off automatically.
To stop the Sure Alarm buzzer immediately, press the RADIO ON/OFF button.
Pressing the SNOOZE button has no effect during Sure Alarm operation.
Note: In order to maximize the life of the built in lithium battery, please be sure
to set the ALARM 1 and ALARM 2 switches to the "OFF"position if the radio
will be disconnected from the AC outlet for more than a few hours. This will
prevent the Sure Alarm from turning 'On'unnecessarily.
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
SET + or - button to move the display ahead or back to your desired wake up
3.) When the desired wake up time appears on the display, release the SET + or
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
