Some lid snaps have a lot of
spring tension once they go over center, have a firm grip on the
lid snap. Lid Snaps may be opened one at a time.

Installing Camera in Housing

Before installing the camera, pull out on the controls in the front
section of the housing. This will allow the camera to slide in
easier. Once the camera is installed and the lid snaps have been

closed, return the controls to their operating position.

Closing the Housing

1. Place housing face down in your
lap.

2. Check to see that there is an o'ring
on the housing back and that it is
clean and in its proper location.

3. Guide the back onto the housing.
The o'ring should touch the
housing all the way around. There
should be an even gap all the way
around between the housing and
the housing back.

4. Lift the lid snaps so they are
extended and place the lid snap
into the hook on the housing back.

5. To close the housing push
down on the lid snaps until
they snap into place . Lid
snaps on opposite sides of the
housing should be closed at the
same time. Be sure they are down
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.

zoom ring. (Fig. 1).

Type 2 Lenses have a lens

opening that IS larger in

diameter than the zoom ring. (Fig. 2).

Zoom Clamps & Gear Sleeves Included with Housing

Installing the Zoom Clamp & Gear Sleeve On the Type 1 Lenses
Installing the Zoom Clamp

The Zoom Clamp has springs so it can be expanded to fit over

the Zoom ring of the lens as shown in (Fig. Q. Install the Zoom

Clamp with the extension tabs toward the rear element of the
lens. After installing the Zoom Clamp, check that when rotating
the Zoom Clamp it rotates the Zoom ring on the lens. If the
Zoom Clamp is not tight enough to rotate the Zoom ring on the
lens, remove the Zoom Clamp and install the rubber strips

(supplied) to the inside of the Zoom Clamp as shown (Fig. F).

Two thicknesses of rubber strips are provided. Start by installing
the thinnest rubber strips, if the Zoom Clamp still is not tight

enough use the thicker rubber strips. Reinstall the Zoom Clamp.

Install the Gear Sleeve

After the Zoom Clamp is installed, lower the appropriate Gear
Sleeve over the Zoom Clamp aligning the Gear Sleeve ribs with the

grooves in the Zoom Clamps extended tabs as shown (Fig. D & E),

Note that the ribs of the Gear Sleeve should slide freely in the
grooves of the Zoom Clamp. If the Gear Sleeve does not slide
freely, remove any rubber strips on the inside of the Zoom Clamp,
if no rubber strips are installed then try using the Zoom Clamp

and Gear Sleeve for Type 2 lenses in the #5509.28 package.

Lower the Gear Sleeve into the port opening of the housing so
the teeth on the Gear Sleeve mesh with the teeth on the housing

Drive Gear (Fig. G). When the port is installed it will lock the

Gear Sleeve in place. After installing the port, rotate the housings
Zoom Control Knob to see that the Gear Sleeve is properly

routing the lenses Zoom ring.
