Rotate the magnetic ring to select the wanted output level.
From left to right, there are five output levels: Battery level, Red light, Off, Low and High.
When rotating the magnetic ring to the battery level output, there are three states: red light constant-on displays sufficient power level, red light slow flash displays poor battery level, red light quick flash displays critical battery level.
The light will accumulate a lot of heat when it is working at High output. When the light is overheated internally up to 65 ℃ or above, the flashlight will automatically adjust the output to prevent the light from overheating.
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, and then screw the tail cap.
Reason A: The batteries need replacing.
Solution: Replace batteries (Please confirm the correct installation of anode and cathode).
Reason B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don’t work, please refer to the warranty policy before contacting your authorized distributor.

This Dive light is absolutely amazing. Did a night dive with this light out in a quarry. Loved the ease of use with being able to switch one handed between each feature. I love how big the beam is. Also there is a red light (great for night vision) that I enjoyed using during the dive and on the surface while setting up. The brightness settings are perfect. This is by far my favorite light. In my opinion this SD20 Dive light out competes competitors lights that are listing in the $300 range. I came up next to my buddies and my beam was just as bright if not brighter than his. The rechargeable batteries are a nice addition as you don’t need to spend money replacing them. Loving this purchase. Definitely recommend this dive light for scuba diving
