Instructions link didn't work, but I couldn't figure out how to go from military time to standard time. Solution: Hold the clock button down until the screen changes - about 5 seconds. You can then hit the hour button to change from 24 H to 12 H.

Copy following link to identify timer and download possible manual.

Reset timer to clear memories.
This is older timer no longer manufactured.
If functionality is not restored after reset, the internal rechargeable battery may be bad.
Don't buy used timers from ebay.

Replace with newest line of inexpensive timers: choose from 1-2 outlets, grounded or polarized. Outlets have same programming schedule.

Intermatic digital lamp timer dt300. I can only get to set it to 24 hour. it does not go to 12 hour when i reset and then hold down the clock button. what am i doing wrong?

There is no repair for defective timer.
The DT300 is sold under at least 3 different brands and product numbers, and each manual shows identical steps for choosing 12H and 24H format.

The manual says to press and hold CLOCK button until display shows 24H. Then press HOUR button to change to 12 hour format.
I am guessing this step cannot be done if timer has programming in memory, so timer has to be reset first by pushing in reset button for a few moments.
