Or do a factory reset….
Restore to Factory Settings
This is a feature, undocumented in the user manual, that will restore all configuration settings to factory defaults, in the
state as originally shipped. It comes in handy in case there’s any doubts of how the light is configured. To access this
feature, while displaying the firmware number (dbl click for voltage display, then dbl click for temperature display, then
dbl click for version display), press&hold the switch until the light blinks quickly – this acknowledges the configuration
settings have been reset to factor defaults.
