Fenix TK22 V2 Troubleshooting StepsUpdated a day ago

These troubleshooting tips apply to the TK22 V2, as well as the discontinued original TK22.

Confirm that the battery or batteries are working properly by testing them in another compatible device.

Make sure the battery or batteries are inserted into the flashlight in the correct direction. The positive (+) end should face the head, or LED end, of the flashlight.

Confirm that there is only one O-ring on the light. The flashlight already has an O-ring installed when it is removed from the box. The additional O-ring included in the box is a spare. If you installed the spare O-ring, please remove it, as having two O-rings will prevent the flashlight from making a full connection with the batteries.

Lubricate the O-ring by applying a small amount of petroleum jelly with the end of a cotton swab.

Confirm that the head and tail cap are installed on the correct ends of the flashlight. The tail cap should be installed on the end where the pocket clip connects. When the flashlight is secured in a pocket using the clip, the LED should face downward.
