    Problem 4: I cannot delete a program

    • Cause: The TM-630S does not have a "delete" key. You must override the program.
    • Fix: Enter the program number (e.g., 5ON). Use ▲/▼ to set the time to --:-- (if supported) OR set the ON and OFF times to exactly the same value (e.g., ON 00:00, OFF 00:00), which effectively disables that program.
