Q6. Why does the TK20R V2.0 downshift to a lower mode after being used for a while and the higher mode cannot be selected?
There are two reasons:
1. Intelligent Overheat Protection
The light will accumulate a lot of heat when used on Turbo 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 Turbo mode.
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 Eco output is reached. When this happens in Eco output mode, the light blinks 3 times every 5 minutes to remind you to timely recharge or replace the battery.
Q7. Why does the TK20R V2.0 happen to flicker?
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.
