1: Introducing the XA25
Congratulations on owning a new Gates product: the XA25 housing. You’ve selected a
product that will provide years of value and reliable service. We designed the XA25
specifically for the Canon XA25, XA20 and HF-G30 digital video cameras.
Please read through this entire guide to learn about the housing so you can get the most
out of this imaging tool. In this section, we’ll introduce you to the features of the XA25 so
you can get started.
Features
The XA25 has several key features:
 Small and Travel-friendly. At just a few pounds, the XA25 packs easily into your
luggage or dive gear.
 ‘Bulletproof’ construction. Gates legendary reliability is inherent in the XA25:
machined aluminum shell, stainless hardware and reliable mechanical controls.
 Precision optics. The XA25 allows the use of a variety of ports including Wide and
Macro.
 Professional Imaging. The XA25 system includes many features for broadcast TV
and other professional uses.
Warranty Disclaimer
The XA25 is a tool that, like any tool, requires knowledge and understanding to be
effective.
Your responsibility is to learn the proper setup, use and care of the XA25. Because we
can only provide you with the information necessary to do so, Gates does not warrant
the contents of your housing (e.g. your camera and lenses) under any circumstance.
For the same reasons, Gates does not warrant optical performance or image quality.
We warrant the XA25 as an image acquisition tool for a period of 2 years. The optional
Seal Check unit is warranted for 1 year. Optics are warranted for a period of 1 year or
100 hours water contact, whichever comes first.
If you have any questions about the setup, use and care of the XA25, contact Gates
directly. Details are in section 5.

Camera Preparation
Your CANON 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 and SD Cards. NOTE that Class 10 SD cards are
required to utilize the highest recording data rate available on the XA25, XA20 and
HF-G30 cameras.
 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.

 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!
 Push in the Power Control.
 Power up the camera. Check all controls for the proper operation before entering
water. (See section 4)
 Install a port. Visually align the bayonet mount on the port with the housing. Mate
the port to the housing, and press. It should seat fully with no gaps around the
base. Rotate the port 90° either direction to fully engage the port. For specific
details, see the section Changing Ports on page 27.
Inspect the parting line for poor
mating, gaps or unevenness.
Push in the Power Control.

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 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.

Tripod / Tripod Adapter
Gates Tripod is a useful accessory for steady, locked down shot, particularly for macro
imaging. The Gates Tripod has extensible arms up to 18in/ 45cm that collapse close to
the housing when not in use.
Two types of Gates Tripods exist: a symmetric version and a newer, asymmetric version
specifically designed for XA25-style housings. Either can be used with the XA25.
Mounting diagrams follow.
The symmetric version of the
Gates Tripod. Use 1/4-20 x.75”L
flat head screws to mount the
adapter, and 1/4-20 x .5”L flat
head screws to mount the tripod
plate.
NOTE: only the Gates Tripod
plate is shown. The extensible
legs and clamps are omitted for
clarity.

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.
The asymmetric version of the
Gates Tripod. Use 1/4-20 x.75”L
flat head screws to mount the
adapter, and 1/4-20 x .5”L flat
head screws to mount the tripod
plate.
NOTE: only the Gates Tripod
plate is shown. The extensible
legs and clamps are omitted for
clarity.

XA25 Operation Page 20
4: XA25 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.
