4.3 Memory Function

If the device is powered off at any lighting mode and remains off for more than 5 seconds, the last used lighting mode will be memorized. The next time you turn it on, the dive beacon will start cycling from the memorized mode by default.

When the battery level is low, the light will automatically step down its output level to remind the user that it's time to charge or replace the battery. If not addressed, the product will automatically turn off after approximately 10 minutes and enter a sleep state.

5. Maintenance

  • To prolong the lifespan of your flashlight, if the battery is exhausted or the flashlight will not be in use for a couple of weeks, please remove the battery from the unit.
  • Regularly check and clean the O-rings to ensure a waterproof seal.
  • Clean the contact surface with alcohol if the light fails to start due to poor contact.
  • Ensure the head and tail are tightened properly for optimal contact and waterproofing.

6. Troubleshooting

Light Fails to Start

Possible Reason Solution
Battery exhausted or incompatible Change battery. Ensure you are using a compatible CR123A or protected 16340 battery.
Battery installed incorrectly Make sure the positive (+) pole is towards the head (cap).
Poor contact Clean the contact surface with alcohol. Tighten the head and tail components.

Mode Changes with Small Vibration

Some users have reported that the function changes with small vibrations. This might be due to a weak battery contact spring. Elongating the spring or adding a 47uF capacitor to the battery input + and ground might help resolve this issue. If the problem persists, please contact customer support.
