Features and Controls
SeaLife add-on Macro and Wide Angle lenses that attach to the exterior lens port of the u/w
case are available (see previous page.)
All the controls (except the shutter button) are on the back. Next to the viewfinder
is the Menu button and Power button. The 4-way controller is used to navigate menu
screens and select images in playback. In record mode you press "left" to change the
flash modes, press "right" to enable self-timer. In playback you press "up" to enable
thumbnail index mode and press "down" to delete images. Press the center to accept
selections in menu mode , in record mode it enables the digital zoom.
The Mode Dial has positions for Record, Playback, Movie and Setup.
The bottom button controls the color LCD and the information overlayed on the review
The built-in flash has modes for Auto, Fill, Red-eye reduction and Off. The range was
unspecified but seems to cover about 1 to 9 feet above water.

The optical viewfinder is a reverse Galilean type with framing target. It has no dioptric
adjustment and shows about 85% of the captured image.
The I/O ports are on the sides of the camera. There is a USB 1.1 for downloading
to the computer, a Video Out with selectable NTSC or PAL format - for playback through a
TV and a DC IN for the 3V AC power adapter.
The DC310 has 8MB of memory built-in and a Secure Digital card slot allows you to greatly
expand your picture taking capabilities. It is compatible with up to 256MB size cards and
will probably work with the even larger 512MB cards as well.
The DC310 is powered by two AA type batteries, high capacity
NiMh batteries from 1800mAh or above are highly recommended. NiMH is rechargeable so
they actually save you money in the long run. You can also use lithium AA photo cells or
one CR-V3 type lithium battery (even though the manual doesn't mention it.) The lithium
type batteries have a very long shelf life and deliver a long runtime but they are only
one-use (throw away) batteries.
And as you can see, regular alkalines are practically useless so don't even consider them. You can't stop at 50 feet and change the batteries ...
