Step 1
Fully charge both lights before use.
The lights are supplied with a USB C charging cable only. A wall charger is not included.
To charge the light, unscrew the bottom half of the light body to expose the USB C charging port.
Make sure the light is completely dry before unscrewing the body or connecting the USB C cable.
Step 2
Connect the supplied USB C cable to the charging port.
Connect the other end to a 5V power source, such as 5V/1A, 5V/2A or 5V/3A.
The red indicator light shows charging is in progress.
When fully charged, the blue light turns on and the red light turns off.
Step 3
Once charging is complete, disconnect the USB C cable.
Screw the bottom half of the light body back on securely before use.
Make sure the seal is clean, seated correctly and free from sand, salt or grit.
Do not use the light underwater if the body seal, charging port or thread appears damaged.
Step 4
Press and hold the button to turn the light on.
The button is located on the top of the light when mounted correctly.
Step 5
Press the button again to cycle through the brightness modes.
Use lower brightness for close subjects, clear water or shallow water.
Use higher brightness for deeper water, darker conditions or wider shots.
Step 6
Adjust the light angle while viewing the camera image.
Angle the lights slightly outward from the camera view to reduce backscatter.
If the image looks too dark in the centre, angle the lights slightly inward or move closer to the subject.
If the image looks too bright or washed out, lower the brightness or angle the lights further outward.
Step 7
Press and hold the button to switch the light off.
Make sure both lights are switched off before rinsing, drying, storing or charging.
Step 8
After use, leave the lights closed and rinse them in fresh water.
Press each switch several times while rinsing to remove salt from around the button.
Allow the lights to dry completely before unscrewing the body or charging.
