Use the manual and get as far along in the programming as possible, and then add a comment with step that is confusing so I can answer that specific step. Then repeat as needed for more help.
DT500 is incandescent timer meant to control a lamp, and not necessarily made for TVs and toaster oven etc.
Timer has limited lifetime warranty.
Manual shows troubleshooting help.
Manual has illustrations that go along with instruction steps. Manual is 4 pages long and exceeds space allowed for posting a free answer. However, I can still help for free, if you add a comment and say exactly what step in the manual you need help with.

I Just downloaded the pdf for the same model. The link to Intermatic is http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/dt500ch.ashx
If that doesn't work then google Intermatic DT500CH pdf and select the return from Intermatic. It's a good timer but not intuitive. I had to look up the manual just to change from daylight savings time.
You will find a pdf file copy of the instruction manual you are looking for at the following link: http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/dt500cl.ashx Have a great day!! :)
When the switch is ON, the light operates in dusk-to-dawn mode. In this mode, the light automatically turns on at sunset and turns off at sunrise. When the switch is off, the light stays off.
Press P (program )on the timer and display will show then change the desired day, time and minute using the D+, H+ and M+ buttons. Press P again to set up another program and repeat the second step as above
Clear memory by pushing the reset button on the timer then reprogram using your current schedule when you want the timer to go off/on. Use the day and clock buttons for this then press enter
No, the timer should not make any noise. The noise should be a result of loose connections which cause arcing, which can make a humming or buzzing sound.
If you find that you still notice the sound, even when the main breaker is off then the problem is not electrical in nature.
Question edited for clarity and add a header in order with spaces and CAPS.
It appears Micromark got out or the timer business. There is a similar one in another Fixya post, and a link to them.
