It's my understanding that the light will reset if the battery is removed for more than 60 seconds.
Yes, but that's the "battery detect soft reset" which will NOT make the light forget its settings.
To make the light forget "everything" you programmed into it you need to do a hard reset:
10. Factory Reset
Please feel free to experiment. You can always return to the original
factory settings by following these steps:
• Reset your flashlight - i.e., remove the battery for 60 seconds and
reinstall. Alternatively, you can turn on your flashlight, remove the
battery compartment (your flashlight will turn off) and then reinstall
the battery compartment without waiting. Your flashlight will light
dimly for 7 seconds to indicate the reset.
• Press and hold the button before the dim reset indication turns off.
The light will become brighter for 10 seconds and then turn off.
Release the button when your flashlight turns off.
• Note: your flashlight will display 5 rapid flashes and no settings are
changed if you release the button before your flashlight turns off.
• Note: your flashlight will display 10 very rapid flashes if there is
insufficient power to memorize the original factory settings.
