3: The CX760 / PJ760 Setup
The CX760 / PJ760 housing requires complete and thorough setup prior to use.
CX760 / PJ760 Housing Preparation
 Open the CX760 / PJ760 shell. Two stainless steel safety latches secure the
housing halves. They have a positive locking feature, so to open them you must
first depress the center bar release while lifting the rear lever.
 Separate the rear half of housing from the front.
 Remove the camera mount. Rotate the lock counterclockwise and slide the mount
to the rear.
 Retract and Rotate controls. Pull out the Manual Dial, Manual Button Select Dial
and Zoom ~ 1 inch or until they stop. Rotate the Power Control clockwise.
Rotate the lock to this position and
slide the camera mount out of the
housing.
Release the latches and separate
the housing shell halves.

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.

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.
Slide camera into housing until fully forward.
Open the LCD fully.
Secure by rotating the lock
clockwise.

The CX760 / PJ760 Setup Page 10
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.

The CX760 / PJ760 Setup Page 11
Handle Installation
 Remove the knurled retainer from the handles, then place the handles just behind
the dovetail found on the bottom of the housing (see photo).
 Slide the handles onto the housing dovetail. It may take firm pressure to fully
seat the handles until they come to a solid stop.
 Attach the knurled retainer to secure the handles onto the housing.
Position the handles behind the
dovetail, then slide the handle forward
onto the housing until it stops.

The CX760 / PJ760 Setup Page 12
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.
Typical Water Alarm installation.

The CX760 / PJ760 Setup Page 13
Seal Check (Optional)
 Seal Check Manual. Follow the procedures in the Seal Check manual for verifying
integrity of the housing and monitor.
NOTE. Pulling a vacuum on the CX760 / PJ760 will take only a few seconds. Be
careful to avoid excessive vacuum greater than 8 in Hg.
Video Out (Optional)
 Camera connection. If you have the video out installed, plug the video connector
into the camera after inserting the camera into the housing.
Microphone (Optional)
 Camera connection. If you have the Submersible Microphone installed, plug the
audio connector into the camera just prior to inserting the camera into the housing.
Final Checks
 Visual Inspection. Look closely at all seal mates – Port and Main Housing seal –
for gaps. Look over the housing one final time.
 Verify operation. As a final check, power on the camera and verify all controls are
functioning normally.
Typical Seal Check fitting

CX760 / PJ760 Operation Page 14
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.

 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.
