Recharging Instructions
Insert the charging plug into the receptacle. Complete recharging takes 3.5 hours minimum.
NOTE: Charging must be carried out in a non-hazardous area. The charging receptacle is located inside the housing
adjacent to the ON button. To gain access, it is necessary to unscrew the knurled plug from the body of the unit. The plug is
secured to the ON button by a safety strap to keep it from being lost. Replace the plug after charging is complete.
It is recommended that the Test Lamp be kept on charge when not in use to prevent excessive battery discharge. The
batteries may be charged an average of 500 times before the battery pack must be replaced.
