Q: Why does the TK35R 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 flashlight will accumulate a lot of heat when used at high 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 voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until the lowest output is reached.

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 batteries.

2. The contact or contact point of the batteries 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.
