Housing shown with accessory wide angle lens.

Wide-Angle Lens

Lens Port

The Lens Port is factory sealed, do not remove.

Treat the glass in the lens port as a camera lens. After use, rinse and gently dry the lens port to avoid water spotting. To clean use a mild soap solution or lens cleaner.

Do not use alcohol or window cleaner on the Lens Port. The Lens Port is threaded so that accessory lenses can be screwed onto the port. The threads are very fine, take care not to cross thread the lens.

Wide angle lenses are available from Inon, Sea & Sea and Epoque. These lenses can be screwed onto the lens port above or below water. These lenses are designed to have water between the front of the port and the accessory lens. Make sure no air bubbles are trapped between the port and the accessory lens. There may be slight vignetting when these wide angle lenses are installed. Any vignetting that occurs can be eliminated by zooming

the camera lens slightly. To properly light subjects when using a wide angle lens an external strobe should be used. Due to the wide angle of coverage of the Inon, Sea & Sea and Epoque lenses, the DS125 Substrobe is recommended or two DS51 Substrobes.

Turn Camera On

Turn the camera on and operate each of the housing controls to get a feel for using the camera in the housing. Take a few pictures above water with the camera in the housing.

Closing the Housing
1.	Place housing face down in your	housing back
	lap or on a flat surface.
2.	Check to see that there is an
	o'ring on the housing back and
	that it is clean and in its proper

Checking Controls

Once the housing has been closed, make sure the housing controls line up with the camera's controls. If the housing controls are misaligned slightly make sure the camera hold down bolt has been tightened down firmly so the camera is flat against the tray.

3.	location.
	Guide the back onto the housing.
	The o'ring should touch the				o'ring
	housing all the way around. There
	should be an even gap all the way		housing
	around between the housing and
4.	the housing back.
	Lift the lid snaps so they are
	extended and place the lid snap			housing back
	into the hook on the housing
	back.
5.	To close the housing push	even gap
	down on the lid snaps until	all 4 sides
	they snap into place . Lid
	snaps on opposite sides of the				o'ring
	housing should be closed at the
	same time. Be sure they are down		housing
	far enough to engage the lock.

Double check - Once the housing is closed, check the o'ring seal. Check the gap between the housing back and the housing, it should be even all the way around.

Look through the clear plastic back at the o'ring. You should see a darkened area where the o'ring is compressed against the housing back. If you do not see an even black compression seal all the way around the back, open the lid snaps, reseat the housing back and close the lid snaps. Visually check the seal again.

Lubricants

1. Ikelite provides silicone lubricant with the housing. We recommend you use only Ikelite lubricant on Ikelite products as some other brands may cause the o'ring to swell and not seal properly.

2. Use only enough lubricant to lightly cover control shafts and o'rings. Wipe off any excess lubricant with a clean cloth. Lubricant is not a sealant, it is used to reduce friction. Excessive lubricant can collect sand and dirt which may interfere with proper sealing.

CAUTION

Never use spray lubricants as the propellant ingredient can cause the plastic housing to crack.

Zoom Control

(NOTE:) After you have used the housing's zoom control it must be returned to the center position to disengage. If the housing zoom control is pushing the zoom lever in either direction you cannot take a picture or access any other function as the camera is receiving a signal from the engaged zoom control.
