4.The remote pressure switch is dual mode. The front is a silent on/off and the middle is momentary on.To achieve 50% brightness mode while using the remote switch quickly press the on/off portion two times.
5. If the dual pressure switch is attached to the gun with Velcro or any other mounting material, be sure to remove it from the gun before unscrewing the tail cap from the light to avoid damage to the tail cap.
6.The IR-350 illuminator will not dim with usage. They are equipped with a low battery warning and a protective shut off feature.When the battery voltage gets low the gun light will give ten blinks approx. 15 minutes prior to shutting off. This safety feature keeps the battery from being completely discharged thus extending the battery life.
7. Completely charge the battery before use, the battery is shipped with only a partial charge.
8.The indicator light for the battery charger will be red while charging then turn green when completely charged.
9. Only use 3.7V protected Li-Ion 18650 rechargeable batteries (Never use 3.7V RCR123A).
10. Battery should remain cold when charging, if battery gets hot stop charging and dispose of the battery. Never use damaged or leaking batteries.
11. Do not store the battery in the light and/or the charger.
12. When the light is not being used for long periods of time, the battery should be stored in a cool, dry place with a charge capacity between 60% and 90%. To achieve this capacity, fully charge the battery then install the battery in the light and run the light for approximately 20 to 30 minutes then remove the battery for storage. This will prolong the life of the battery.
