4.2 Twist Focus (Pure Beam Optic)
The PX1 utilizes a Pure Beam Focusing Optic with a Twist Focus mechanism to adjust the beam pattern.
- To switch to a Flood Beam, twist the head of the flashlight counter-clockwise. This mode provides a wide, evenly distributed circle of light, ideal for illuminating a large area without dark spots.
- To switch to a Spot Beam, twist the head of the flashlight clockwise. This mode concentrates the light into a tight beam, reaching far downrange with a transitional halo for peripheral viewing.

5. Maintenance
- Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace AAA batteries when the light output diminishes significantly. Always use fresh batteries of the same type.
- Storage: If storing the flashlight for an extended period, remove the batteries to prevent leakage and potential damage.
- O-Rings: Periodically inspect the O-rings for wear and tear. Lubricate with silicone grease if necessary to maintain water resistance.
6. Troubleshooting
6.1 Light Not Turning On
- Check Batteries: Ensure batteries are correctly inserted with proper polarity and are not depleted. Replace if necessary.
- Tail Cap Connection: Verify that the tail cap is fully tightened. A loose tail cap can prevent electrical contact.
- Clean Contacts: Inspect battery contacts and clean them if there is any corrosion or dirt.
6.2 Dim or Flickering Light
- Battery Level: Batteries may be low. Replace with fresh AAA batteries.
- Loose Connections: Ensure the tail cap and head assembly are securely tightened.
