Fenix HM65R Troubleshooting StepsUpdated a day ago

If your light will not turn on or charge, remove the plastic insulation disc from inside the flashlight body before using it. Please watch the video for instructions.

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 light in the correct direction, as indicated inside the battery compartment.

Confirm that there is only one O-ring on the light. The light 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 light 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 battery cap is screwed on completely.

If the light flashes several times when you press either button, it may be in lockout mode. Lockout mode prevents the headlamp from being activated accidentally. To lock or unlock the headlamp, press and hold both switches for three seconds.

If the light is still not working after you have completed these troubleshooting steps, please visit our Warranty and Repair page to review the policy and submit a claim.
