I am uncertain how to present this to you. Press the ALARM ON/OFF button to turn off the alarm.
If you want to turn on the alarm again, press the ALARM ON/OFF button once more.
Detailed instructions regarding the controls can be found in a manual I think available at the following location: Sharp Alarm Clock Manuals and User Guides PDF Preview and Download (all-guidesbox.com)
I don't have a guide to the internals of this clock but here is a tear down of a similar model if you are game to explore the workings. You could go through that and maybe get an idea of how the systems work together. If you are unable to fix the problem, you will find the contact details for Sharp support in the manual.

To set the time:
Make sure the 'power' is OFF by depressing the PWR button
Depress MODE to start the setup and depress that key to accept each setting
The SPC900 has 2 alarms. On the back of the unit there is a buttion labeled "Alarm On/Off". Press the that button to cycle through the alarm on/off possibilties. On the screen you will see what alarm(s) is (are) turned on. There are4 possible settings: off (no alarms displayed), alarm 1 only, alarm 2 only or both alarms. The indicators are just above the seconds display and to the right of the big hour/minute display.
Look over your player and see if a program is set. Sometimes you can set a program on the CD player to play the first song on cds. Turn program play off. It’s sometimes called delete bank where all song are skipped except first track. Or you can have the repeat button on. Turn that off. There also could be a malfunction with the player. If your still having problems reset the system.
