Unlock: with the light locked, simultaneously press and hold both switches for 1 second, the light will be unlocked and activated on the previously used output. *In locked status, clicking or pressing either of the switches will activate 2 one-second blinks on white light to indicate locked status. 

Intelligent Memory Circuit The light memorizes the last selected output. When turned on again the previously used output will be recalled. 

Laser Sight Zeroing 

1. The windage adjustment is at the left side of the light. Use the included Allen wrench clockwise or counter-clockwise to move the laser point.
2. The elevation adjustment is located at the bottom of the light, Use the included Allen wrench clockwise or counter-clockwise to move the laser point.
3. When making large adjustments there may be an interaction that causes the laser to move diagonally or bind. It may become necessary to rotate the opposing adjustment screw counterclockwise to allow the laser cartridge to move to the desired position.

*Laser parameters: CLASS 3R laser product, laser wavelength 640-660nm, laser optical power output <5mW. 

Battery Specifications 

*16340 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion; but cell damage or short circuiting are potential risks the user assumes. 

Battery Installation/Removal
FOR SAFETY PURPOSES, THE LIGHT MUST BE REMOVED FROM THE FIREARM BEFORE THE BATTERY COMPARTMENT IS OPENED OR CLOSED. 

1. Unscrew and remove the face cap assembly from the body of the light.
2. Insert a CR123A or a 16340 battery with the cathode side (-) towards the light head.
3. Fully tighten the face cap assembly to ensure that the battery makes complete contact with the internal electrical contacts.

Intelligent Overheat Protection 
The light will accumulate a lot of heat when used on higher output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of higher modes. 

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until to 50 lumens. When this happens in 50 lumens, the light blinks 3 times every 5 minutes to remind you to recharge or replace the battery. Note: This only works with Fenix ARB-L16 Series16340 rechargeable Li-ion battery. 

Usage and Maintenance 
IT IS IMPERATIVE THAT SAFETY MEASURES BE EMPLOYED AT ALL TIMES WHILE HANDLING THE FIREARM. 

• The use of a firearm under any circumstance may be dangerous. SERIOUS INJURY OR EVEN DEATH may result without proper training in the safe handling of firearms. Proper training should be obtained from an accredited firearms safety program conducted by competent, qualified instructors in the military, police academies or National Rifle Association affiliated instruction programs.
• Read your firearm’s manual before attaching your gun-mounted light.
• Never point a firearm at something you are not willing to destroy.
• Fenix recommends that the GL22 should only be activated with the non-trigger hand while employing a two-hand grip on the firearm and with the trigger finger outside the trigger guard when possible. Failure to do so could result in an accidental discharge and serious injury, damage to property, or death.
• Thoroughly practice (employing safe training conditions) with the GL22 and firearm before using the weapon in a tactical situation.
• If you shoot ammunition get the lens coated, try rubbing the lens with fine steel wool or Froglube clp.
• Since gun maintenance requires the use of organic solvents, organic solvents contaminating key components of the light or laser module may cause malfunctions, and the light will not receive normal warranty service.
• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using only a high-quality protected battery.
• If the light will not be used for an extended period, remove the battery for proper storage.
• Lock the light or remove the battery to prevent accidental activation during storage or transportation.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare．
• Periodic cleaning of the battery contacts improves the light's performance as dirty contacts may cause the light to flicker, shine intermittently or even fail to illuminate for the following reasons: A: Poor battery level. Solution: Recharge or replace the battery. B: The contact or contact point of the battery or flashlight is dirty. Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.
