Camera Preparation
Your Sony camera will need some preparation before installing into the housing.
Remove any lens caps or external lenses you may have added to the front of the
camera.
Install a charged battery.
Tighten the hand strap to its shortest position and tuck the ‘tail’ back into the hand
strap.
 CAUTION: Failure to perform this step may result in the hand strap becoming caught
in the housing seal and accidental flooding.
Install the camera onto the camera mount using one of the short ¼-20 flat head
screws by threading into the tripod mount found on the bottom of the camera. A
screwdriver or coin may be used to tighten snug, but do not over tighten.
Remove any lens
caps or filters.
Tighten the handstrap to
its shortest position.
Install the camera mount
as shown. Tighten the ¼20 screw gently and snug.

Installing the Camera into the Housing
Carefully slide camera on its camera mount into the front housing half. The
camera mount will mate and slide into the mating mount on the housing.
Observe that the camera mates into the alignment collar at the front of the shell,
just behind the port opening.
Secure the camera by rotating the lock clockwise until snug.
Press in controls. When the camera is installed into the front housing half, press
in the Manual Button and Manual Dial controls to mate with the camera.
Check controls. At this point it’s a good idea to check all controls on the front shell
for proper operation. (See section 4 for controls mentioned here.)
Open the LCD fully.

Closing the Housing
Carefully inspect o-ring on back half and the sealing surface on front half. Make
sure they are clean and in good condition.
Place back half onto the front housing half. You will clearly see when the
housing halves align and seat together properly.
Locate and close the two latches at the same time.
 CAUTION: The safety latches must be closed and locked prior to use to avoid
opening underwater. It is your responsibility to make sure the latches are secure,
locked, and in good condition. DO NOT enter the water with a faulty latch. Gates
will replace a damaged or faulty latch free of charge.
Carefully inspect the parting line between front and rear housing. If this line is
not even all the way around, remove the back and determine the reason. (O-ring
out of place, hand strap interference, etc.) Failure To Do This May Result In A Wet
Camera!
Press controls in until they touch camera buttons. Note positioning of each
control as it touches the camera button/switch it is designed to actuate. (See
Section 4)
Power up the camera. Check all controls for the proper operation before entering
water. (See section 4)
Check the Port. It should be seated flush on the front bulkhead with no uneven
gaps. If the port is not seated properly, remove the port and re-install per directions
in a subsequent section of this document. Also check that the dot or indent on the
port is aligned with the dot on the housing.
Mate the shells and close the two
latches. The shells should mate
without obstruction.
Note: HF-S21 housing shown.
Once closed, check the
parting line for gaps.

Water Alarm (Optional)
If you have the optional water alarm installed there are three alarm conditions to know:
Condition
LED
Siren
New Battery
(Insertion)
Bright Intense blink
while siren plays
Ascending tones played 4 times
Water Intrusion
Bright Intense Blink
Grating Warble sound. Alarm will
sound for duration of detection.
Low Battery
Low Intensity fast blink
Descending tones played 8 times
pausing approx. 20 seconds between
plays after alarm test or water
detection.
The alarm can tested anytime by shorting the detection contacts that lead to the water
alarm transducer. The water detection condition will activate for 6 seconds. If the battery
is drained the low battery condition will sound.
The water alarm requires a single 6V battery
like Radio Shack model 23-469 or A544.
Your battery should be removed when stored
(e.g. between dive trips). Check the battery
prior to every dive to ensure proper operation.
Change when indicated.
 CAUTION: You must wait a minimum of
30 seconds between battery insertions to
allow the unit to fully discharge.

4: CX760 / PJ760 Operation
Your Gates housing utilizes 100% mechanical controls to provide you with the most
reliable operation possible. They either rotate and/or depress to provide smooth and
consistent operation. (see ‘Housing Care and Maintenance’ section).
The housing controls are designed by Gates engineers, to the extent possible, to feel
and behave like the camera controls. With time and use, the housing controls will
become quite familiar and easy to use.
To help familiarize you with the housing controls, Gates recommends reviewing each
control individually, how it actuates the corresponding camera control, and operating it to
get a ‘feel’ for the control. You can view all front housing controls with the housing
open. After reviewing all controls, perform a ‘simulated’ dive by operating the controls as
you would in the water.
One final note about controls: when operating any control out of water, you may need to
press the control against the housing, into the position it would naturally find while under
water pressure. The controls are designed to operate properly in this position.

Right Side Controls
Record / Standby. The Record/Standby control is red and operates with a
momentary clockwise rotation.
Photo. This control operates similarly with a clockwise rotation. Press and hold
long enough for the camera to focus and capture a photo.
Top Controls
Zoom. The Zoom control is blue and operates with a momentary rotation.
 TIP: The Zoom control operates free and smooth when well lubricated. This should
be done after storage and often during heavy use (as much as every 2 or 3 dives).
To lubricate, pull up the control to expose a portion of the control shaft, and lightly
apply silicone. Push the control back in and rotate both directions until it operates
freely.

Changing Filters
The color correction filter in your housing may be changed to accommodate different
gradient filters. “Blue water” and “green water” are the two most common, recognizable
by their orange and purple color, respectively.
Removal. The color filter is held in place by a tension screw in the filter holder.
Loosen this screw with a 1/16 Allen tool.
Installation. Rest the filter in the holder and tighten with a 1/16 Allen tool. Tighten
just enough to secure the filter. Do not over tighten.
Cleaning. You will likely have fingerprints on the filter after installing, so clean the
filter according to the directions in the “Cleaning Ports and Filters” section.
Use a 1/16 Allen tool to
remove the filter from the
holder. The screw closest
to the filter is loosened.

Changing Ports
Gates offers several ports for your CX760 / PJ760 housing, which attach with a bayonetstyle mount. Port changes are easy and straightforward:
Removal. You will see alignment dots on the housing and on the port. When
aligned, the port is fully engaged and ready for underwater use. Turning the port 90
degrees, or ¼ turn in either direction to face the dot left or right allows the port to
release from the front of the housing. Gently pull the port directly away from the
housing to do so.
Inspect the o-ring -- Before installing a new port, perform an inspection and
lubrication of the sealing o-ring. See “O-ring Care and Maintenance” in this Use
and Care Guide for specific details.
Installation. Mounting a different port is directly the opposite: Insert the port into
the front bulkhead of the housing with the alignment dot on the port facing left or
right, or ¼ turn away from the dot on the top of the housing. You may need to
gently push the port into the bulkhead to fully seat the port. Then turn the port until
the dot on the port aligns with the dot on the housing. Be sure the port is fully
seated and flush with the housing. You should see no gaps between the port and
the housing.
 CAUTION: The Port must be fully seated and flush with the housing to avoid
flooding.
Align dot on port and housing.

Using the GP32A Wide Angle Port
Super Range image stabilization. With the CX760 / PJ760 camera only, you may
find momentary vignetting occurs with swift movements left or right when using
Super Range image stabilization. If so, make smooth pans to either side, or change
the image stabilization to Standard mode.
Photo Mode. Due to variations in cameras you may find very slight vignetting in
Photo Mode and at highest picture size (L 3264 x 2456). To avoid this, it may be
necessary to zoom ~ 2% from full wide. One momentary action on the zoom control
toward telephoto is sufficient.
Cleaning Ports and Filters
Gates ports can be cleaned readily by following these simple guidelines.
Dust or Lint can be blown with compressed air, preferably from a can. Do not
clean the surfaces if it is unnecessary.
Salt deposits or sand may also be removed with compressed air. Use a soft
lens brush if necessary to brush away foreign material that remains.
Rinse fresh water over the outside of the port, if necessary, to loosen any
residual salt or sand that may remain. Do this with the port sealed on your housing
to keep water away from the rear of the port.
 CAUTION: Do not submerge the GP32A wide angle port in water when separated
from the housing! This port is not sealed from the backside and damage will result if
submerged.
Only if necessary, clean the port using a mild cleaning solution and a nonabrasive, lint free cloth. Use light circular strokes when wiping away cleaning
solution and any foreign material. Excessive pressure used when cleaning dirty
lenses (e.g., rubbing sand into the lens surfaces) may damage coatings. Use a light
touch.
 CAUTION: Not all cloths are lint free and non-abrasive! Use of an abrasive material
(such as cotton balls and cotton fabric) may scratch the glass and/or coating of
Gates ports and will void the warranty.
 TIP: Gates offers approved cleaning solutions and lint free cloths as accessory
items. Use of these materials will not void your warranty.
CX760 / PJ760 Operation

Diopters
Diopters may be used with the CX760 / PJ760 housing and the FP32A Flat Port for
close up/macro imaging. There is sufficient space between the camera and port to
utilize up to three diopters stacked on the camera. The camera utilizes diopters in a
52mm holder.
 NOTE the Filter cannot be used with diopters. When installing the camera with
diopters ensure the filter is positioned as far as possible away from the port opening.

Tips for Shooting Video with the CX760 / PJ760
Zoom. Zoom shots can be used for good effect, such as ranging telephoto to wide
to highlight critter camouflage. Smooth, steady zoom is generally best for such
shots, and is achieved by setting your camera zoom slider to do so. In the camera
menu are four settings: Variable and Speeds 1 through 3. Variable will, as the
name suggests, zoom slow to fast depending on how far you move the zoom slider,
and is difficult to control for that smooth, steady zoom. Speed 2 or 3 is
recommended, and provides a constant zoom rate regardless of the zoom slider
position.
Manual Focus. The CX760 / PJ760 housing allows direct access to the Manual
Dial and Manual Button on the camera. These buttons can have a variety of
functions assigned to them, but a common and useful function underwater is
manual focus. With this setting you can prevent the camera from auto ‘hunting’ or
‘seeking’ to find focus.
A common technique is allowing the camera to auto focus on your subject (or on
something about the same distance from you as your subject), then switch to
manual focus. This ‘freezes’ the focus at that distance – no hunting or seeking.
The GP32A wide angle port further provides a large depth of field (DOF), so most
everything in front of your camera will be in focus, too.
Image Stabilization. The Sony CX760 and PJ760 cameras have built-in image
stabilization functions. These are useful underwater for steady, even shots, so you
should have image stabilization turned on.
One note, however: this technology can be quite forgiving to shaky hands, but does
so at the expense of playing ‘catch up’ to your subject. That is, if you move the
camera left to right you may notice the image ‘catches up’ and keeps moving even
though you’ve stopped moving the camera.
This technology can also have an adverse effect in the form of vignetting. With the
GP32A port in particular, you may see momentary black corners with sharp
movement of the camera. To avoid this, set the CX760 / PJ760 cameras with
image stabilization mode off.

Lighting Systems
Your housing comes ready to accept different lighting systems depending on your
requirements. If you purchased lighting systems from Gates you will find a separate
document to guide you through installation to your Gates CX760 / PJ760 housing.
Housing Care and Maintenance
Proper care of your Gates housing is important to provide you reliable operation and
long life. You’ll find all the guidelines in the “Housing Care and Maintenance” document
included with your Gates housing. You can also find it on Gates web site at
www.GatesHousings.com.
O-Ring Care and Maintenance
Your Gates housing has 2 serviceable o-rings. One is located between the mating
halves of the housing (the large orange one), and one is located on the Port.
Servicing the o-rings is easy and covered in the “Housing Care and Maintenance”
document in this package. It can also be found on the Gates website at
www.gateshousings.com.
 CAUTION: Do not lubricate the large orange o-ring! It is a special silicone oring and can be damaged by petroleum-based lubricants.
 CAUTION: Never use metal tools or objects for removing o-rings!
