Setup

Follow these steps to prepare your Genwiss GN-T41 dive flashlight for first use:

  1. Battery Installation: Unscrew the tail cap of the flashlight. Insert the included Lithium Ion battery with the positive (+) end facing towards the head of the flashlight. Ensure the battery is seated correctly.
  2. O-ring Lubrication: Before screwing the tail cap back on, apply a small amount of silicone grease (not included) to the O-rings. This ensures a watertight seal and prevents damage to the O-rings. Do not add extra O-rings; the included spare O-rings are for replacement only.
  3. Secure Tail Cap: Carefully thread the tail cap back onto the flashlight, ensuring it is tightened securely to prevent water ingress. Do not overtighten.
  4. Charging: Use the provided charger to charge the battery. The charger typically indicates charging status (e.g., red for charging, green for fully charged). Connect the charger to a USB power source (computer, power bank, car charger, or wall adapter).
