after each use. Push each button 20 times to flush out any trapped
salt or debris. Fully dry the housing with clean towel before opening.
•Do not attempt to service the camera. Contact your local authorized
SeaLife dealer if the camera requires service.

baggage. Always put batteries in your carry-on bag. To prevent
short-circuiting or fire, keep the battery away from other metal objects.
•When you are using a new battery or if the battery has not been used
for an extended period, we recommend fully charging and discharging
the battery once to maximize battery life.
•Only use the ReefMaster battery (item # SL3504) included. Using
other batteries may cause damage and void the warranty.

VI. Camera settings and menus
In Playback/Settings mode, you can adjust the Photo settings, Video
settings, System settings or playback photos and videos.
Photo settings
This menu is used to change still photo settings. Some photo settings are
also found in the Video settings menu. For example, the White Balance
setting is in the Photo and Video settings menu. Changing one of these
duplicate settings will apply to both photos and videos.
White Balance (WB)
Select from 8 different white balance settings depending on specific
ambient lighting conditions to optimize the photo and video color
reproduction.
•Auto: Automatically selects best white balance for land (not for
underwater).
•Underwater Shallow: Ideal for shooting underwater images and videos
at depths less than 25ft/8m.
•Underwater Deep: Ideal for shooting underwater images and videos at
depths greater than 25ft/8m.
•Daylight: Ideal for shooting outdoors in sunny conditions.
•Cloudy: Ideal for shooting outdoors in cloudy conditions.
•Tungsten: Ideal for shooting indoors under tungsten lighting
•Fluorescent: Ideal for shooting indoors under fluorescent lighting
Exposure Compensation

19
This setting adjusts the camera’s auto exposure program to be slightly
overexposed or under-exposed. Increasing the value (+) results in a
brighter image exposure. Decreasing the value (-) results in a darker
image exposure. The Exposure Compensation values range from +2.0 to
-2.0 in 0.3 step increments. Each step is equivalent to 1 exposure stop.
Photo Burst
Use this setting to capture a series of photos with one push of the shutter
button.
•Off: Photo Burst is disabled. Pushing the shutter will capture 1 photo.
•3 Shots / 1 Sec: Shoots 3 photos in 1 second
•7 Shots / 2 Sec: Shoots 7 photos in 2 second
•15 Shots / 4 Sec: Shoots 15 photos in 4 seconds
•30 Shots / 8 Sec: Shoots 30 photos in 8 seconds
ISO
ISO adjusts how sensitive the image sensor is to light. Select between
Auto, 100, 200, 400 or 800. The higher the ISO value, the more sensitive
the camera will be to light. A higher ISO is useful when taking photos in
low light conditions but will result in a grainier, less sharp picture. The
lower the ISO value, the less sensitive the camera will be to light. A lower
ISO value is useful for ideal for brighter light shooting conditions and
results in the sharpest image quality. Selecting AUTO ISO automatically
selects the optimal setting.
Metering
This sets the area within the image frame that the camera uses to adjust
photo and video exposure.
•Multi: The entire area of the image frame is measured to adjust
exposure. Recommended setting.
•Center: The entire area of the image frame is measured to adjust
exposure but greater weight is given to the subject area at the center.
•Spot: Only the center of the screen is measured to adjust exposure.
Useful for optimal exposure of bright objects located in the center of
