Set white noise on model spc570 clock - Sharp Audio Players & Recorders

press the mode button to get 24 or 12--- set on 12

Most likely control board is flaky. I need a model number please.

How do you set the alarm on this clock?

All you have to do is press and hold the - (minus) button on the front of the alarm clock to toggle it between 24h and the 12h format. But only when in normal operation mode. If you are in any of the setting modes it will obviously change whatever setting your in in a downward direction.

You can get the manual on the link below. Just click on Operating Instructions

1) Yes, the noise is from clock motor turning the gears.
When timer is new, parts have a bit of white grease on them.
Turn off power and spray WD 40 or apply some white grease and see if that helps.

2) Yes WG1573 240Volt clock motor is going bad.
Tip out mechanism using thumb spring located top inside box and check clock motor number.

Buy WG1573 240Volt clock motor and extra trippers from Granger number 1PNK2

A) How to wire t1905 for 125V
You will have four wires >> a Black and White from breaker box; and a Black and White to load

1) Black hot wire from breaker connects to COM
2) White neutral wire from breaker box connects to Clock
3) White neutral wire to load connects to Clock
4) Black wire to load connects to NO -or- NC screw [one of these screws will have no wire attached]

Push the clock button,then push the up or down temperature arrows to set the clock. After it is set,push the clock button again.

F-1 USUALLY MEENS THE MAIN PCB OR CLOCK ***. I WOULD RECOMEND REMOVING THE POWER AND PULLING IT AWAY FROM THE WALL .TAKE THE BACK PANNEL OFF AND LOOK FOR A BURN MARK. THAT SHOULD SHOW WHAT BLEW.
GOOD LUCK!

You didn't mention a model number. If you have a touchpad, press clock turn temperature control up or down. When the correct time is set, press clock again.
