I don't have a manual for my GE clock radio model 7-4809. How do I set the alarm. FK

There is no manual. This unit is considered vintage from a time before the Internet and its repository of manuals.

These that the closest.

I have one & I just set it. You hold down the s button until the time flashes then use the arrow buttons to set hour then push the s again to set minutes & when they flash you push the arrow button again then repeat with the alarm & date.

Please download the user's manual from here:

http://www.nodevice.com/user_manual/download_346371.html

Then read pages 14-15 for setting the time and pages 16-18 for setting the alarms. This guide is detailed and good enough.
Good luck!
Thanks.

Good Luck and please rate 4 thumbs up for the free answer.

Push the SET WAKE/TIME button on the far right of all the buttons - it's the button closest to the CD player. Push it until the 1 or 2 show up on the display - whichever one you want to use. The push the CD player's forward button - the one with the two right-facing arrows - until the time you want to wake up shows up in the display. That's it. To turn the alarm off, push the WAKE CANCEL button, below the set wake/time button, the push the 1 or 2 button, depending on which alarm you want to turn off. The display will show OFF in the alarm you chose.

What I have found with my alarm clock like this one is that you CANNOT be soft on it. When setting the time, hold down the F or R button extra hard. I know that seems odd, but it works!
