The TD-1K module contains a feature that shuts off the power automatically after it has not been used for a period of time. This is called "Auto Off."
You can either customize the Auto-Off time, or disable the feature altogether. Here's how:
1. Turn on the power.
2. Press and hold the metronome button until the DRUMS indicator flashes.
3. Release the metronome button, and then press the SELECT button repeatedly until the SONG indicator is flashing.
4. Press the (+) or ( - ) button to choose the desired setting: 240 (minutes), 30, 10, OFF.
5. Press the metronome button when you're finished. The new setting is saved automatically.
