WARNING. These user instructions do not replace the AP Diving Rebreather
Manual in any way and do not explain the full rebreather functionality. These
instructions will detail the HUS as part of the rebreather system only.
WARNING. The HUS has optics that are designed for use underwater and as
such the display is remarkably clearer underwater than on the surface. On
the surface you have to focus on the display, however underwater, there is
no need to focus at all, the complete display is in focus at all times.

HUS –Head Up Screen
AP Diving’s HUS or Head Up Screen (RB130) is a near-eye, hands free secondary
display that shows the diver real-time information directly from the rebreather’s
oxygen controller electronics. The clever underwater optical lens magnifies the
display so it appears as if it is a 15”TV approximately 1 metre away. This gives live
rebreather information in the line of sight for the complete dive, without the need to
refocus. For many prescriptions normally removing the need for special masks or
lenses to compensate for poor eyesight. The HUS has been specially developed for
use with AP Diving’s range of rebreathers, equipped with Vision electronics and is
intended as an upgrade for existing customers as well as an optional item with new
AP Diving rebreathers.
The HUS is mounted on the rebreather mouthpiece using an adjustable articulated
mounting arm allowing bespoke positioning of the device to give the optimal view of
the display without compromising the diver’s vision of the diving environment. Due to
the mounting being so close to the mask, the HUS can be read in very low visibility
conditions where the conventional wrist mounted primary display would be more
awkward to read. This style of display also allows true hands free diving whilst still
monitoring the rebreather at all times. Excellent for photographers, videographers
and people who require two hands to work or play underwater.
The full colour display conveys all the key rebreather information with the added
benefit of conditional colouring to highlight the current status of the information
provided.
The HUS is driven by a bespoke I2C channel, the same I2C connection that delivers
the display information to the Handset. For this reason the HUS is provided in
addition to the HUD, as the HUD is driven by raw PPO2values direct from the oxygen
controllers and therefore can be used to fly the rebreather in the unlikely event of an
I2C communication failure.

Important Information
DO: Read the instruction manual fully before using the rebreather
DO: Carry out all pre-dive checks prior to each dive
DO: Protect the HUS against shock at all times and avoid scratches on the
lens by replacing the lens protector if it starts to peel
DO: Make sure that the HUS is free from mechanical damage and that the
lens is not impeded in any way that could affect its use
DO: Wash the HUS with fresh water after each dive to avoid any salt or dirt
build up
DO NOT: Ignore warnings displayed by the HUS
DO NOT: Dive without sufficient battery power or enter the water until the
rebreather is correctly calibrated and in surface mode
DO NOT: Mount the HUS in any way that obstructs the use of other rebreather
functions, such as operating the mouthpiece / OCB, or the view of the
handset
DO NOT: Attempt to open the HUS as it is designed as a sealed unit
DO NOT: Attempt to modify the rebreather and HUS in any way
DO NOT: Use chemicals to clean the HUS

Parts Supplied
Note: The HUS is a sealed potted unit and no attempt should be made to
disassemble the housing in any way. Trying to do so could cause irreversible
damage to the display and electronics.

HUS Assembly / Mounting
The HUS comes factory fitted to the Rebreather Lid. It is wired into the controllers
through a new buzzer housing. The rebreather firmware must be V06.00.00 or higher
for the HUS to work and this will be installed as standard. We recommend that the
HUS is assembled within the Rebreather using the following procedure:
1. Compress exhale mouthpiece hose next to the mouthpiece hose fittings
2. Whilst compressed, thread the HUS mounting arm over the hose

A P D i v i n g H U S P a g e | 8
3. Slide the mounting arm onto the hose fitting where it should snap into place
4. Prior to mounting the HUS, it is recommend that the HUS cable is wrapped
around the convoluted hose to prevent the cable from becoming a snag
hazard. Depending on the rebreather setup and hose lengths, it may be
necessary to wrap the cable around several times to take up extra length.
5. Slide the HUS into the mounting arm from the front until the clip is at the
bottom of the HUS barrel
A P D i v i n g H U S P a g e | 9
6. Rotate the mounting arm around the hose fitting and manipulate the
articulated arm to position the HUS into an approximate position (as if it would
point towards the mask)
7. When wearing the unit reposition the HUS to the desired position for your
particular mask and preferences.
The nature of the articulated arm means that very fine position adjustments are
possible, and alterations can be made at any time prior to or during the dive. The
HUS arm length can be adjusted by removing or adding push-together sections.

Pre-Dive / Surface Mode
Whilst the rebreather goes through its start-up process and self-tests, the HUS
displays the AP Diving logo.
During this time the diver will be looking at the primary display (handset) and
confirming the electronic checklist.
