    *In locked status, clicking or pressing either of the switches will activate 2 one-second blinks on white light to indicate locked status.

    Q7. The battery indicator of GL19R can be turned off and how to turn off?

    A: If you want to turn off the battery indicator when using the tactical light, constantly click the switch close to the battery indicator 3 times with the tactical light switched off. By the last time clicking, the battery indicator lights up (green-red-green) to remind the user that the battery indicator has been turned off. At this time, the battery indicator will not light up when the tactical light is turned on, but the charging status will be displayed normally when the light is connected to a power source. You can reactivate the battery indicator function by reloading the battery or by repeating the above operation when the light is turned off.

    Q8. Why does the GL19R downshift to a lower mode after being used for a while and the higher mode cannot be selected?

    A: There are two reasons:

    1. 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.

    2. 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.

    Q9. Why does the GL19R happen to flicker?

    A: The reasons that may cause the light to flicker, shine intermittently or even fail to illuminate:

    1. Poor battery level.

    Solution: Recharge or replace the battery.

    2. 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.

    A: It is recommended to use Fenix 18350 ARB-L18-1100P battery. Other Li-ion batteries are not recommended. As Higher modes fail to light up due to current and voltage limitation, an unmatched battery may cause the light to fail to work normally.
