If you are not ready to wake up just yet, you can press the AJ3540/37's Repeat Alarm button, and the alarm will go off again in a few minutes. You can set two different alarm times with this clock, one for you and one for your partner. You can use the Sleep Timer feature to fall asleep to your favorite radio station or CD by setting a time limit for how long it should play. After the radio is finished playing your music, it will slip into a power-efficient stand-by mode. This clock radio lacks the higher cost AJ3231/37's MP3 link, though this radio has a larger display than the AJ3231/37. This clock also lacks the higher cost AJ3600/37's premium features like Time Projection, digital tuning with presets, and Gentle Wake.
