Press and hold the DOWN button for more than 12 seconds to restore all default settings. Installation and Safety Tomzn Voltage Protector
Automatic cutoff during over-voltage (230V–300V) or under-voltage (140V–210V) events. Look at the top of the unit: :
Set the undervoltage threshold just below your normal minimum voltage—enough to detect a brownout or sag without nuisance tripping.
