Q: Why does the TK22R 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.
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 the Low mode is reached.
