Operation

• Turn On/Off 
  Press the side switch to turn the light on/off.
• Change Mode
  
  • When the light is on, long press the side switch to cycle through low, medium and high.
  • Shortcut to firefly: When the light is off, long press the side switch to get firefly mode.
  • Double click to turn to turbo from any mode. Another double click to get strobe.
• ITC Technology
  The light will automatically lower the current when temperature in LED or driver rises to 80 degrees centigrade to protect the flashlight from overheating. Thus to extend its lifespan.
• Memory Function
  The light will turn on in the last mode accessed, except firefly, turbo and strobe. 
• Low Voltage Indication
  When the indicating light on the side switch turns from blue to red, it means the batteries should be replaced or charged.
  
• Battery Replacement:
  Take off the tail cap, insert four 18650 batteries into the battery carrier, put the carrier into the flashlight and screw on the tail cap. With either end of the battery carrier towards the light head is OK. But make sure the batteries are correctly inserted into the carrier with polarities matched (springs on the carrier should connect with the cathodes of batteries).
