To save energy, the drum module will power off automatically after 30 minutes of no activity. If you do not need this feature, disable it by powering off the drum module, and then pressing and holding the Start/Stop button while powering it back on. "PoF" will appear on the display to confirm the feature is off. Note: After powering off, this feature will be re-enabled. Repeat the procedure above to disable it each time you power on the module. Which pads are you striking that cause the module to power off automatically? If you strike a different combination of pads, does the module still power off?
