Charging; Intelligent Protection; Usage And Maintenance - Fenix TK26R Quick Start Manual

Charging

1. First switch off the light and plug the USB A socket of the charging cable into an electrical
outlet, then connect the USB Type-C socket of the charging cable to the light.
2. The indicator will display red while charging, and will turn to green when fully charged.
3. Once charging is completed, be sure to close the anti-dust cover. (The light features inner
waterproofing treatment, thus the performance won't compromise even if there is water in the
charging port ).
Note:
1. The normal charging time of the included Fenix ARB-L18-3500 rechargeable Li-ion battery is
approximately 3 hours from depletion to full charging.
2. Recharge a stored light every four months to maintain optimum performance of the battery.
3. Low output can be turned on/off by functional side switch while charging. There will be no
response upon operation of tail switches while charging. If the tactical tail switch is mistakenly
operated during charging process, then unplug the charging cable and press the tactical tail
switch to begin charging again.

Intelligent Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods.
When the light reaches a temperature of 65°C or above, the light will automatically step down by
a few lumens to reduce temperature. When the temperature is reduced, the output will gradually
return to Turbo.

Usage and Maintenance

Disassembling the sealed head can cause damage to the light and will void the warranty.
