Page 2: Table Of Contents
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. -
Page 3: Hus - Head Up Screen
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. -
Page 4: Hus Features
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 Wash the HUS with fresh water after each dive to avoid any salt or dirt build up... -

Page 7: 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. - Page 8 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...
- Page 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.

Page 10: Pre-Dive / Surface Mode
Pre-Dive / Surface Mode Whilst the rebreather goes through its start-up process and self-tests, the HUS displays the AP Diving logo. Handset Display BATTERY TEST 5.7v 5.8v Display During this time the diver will be looking at the primary display (handset) and confirming the electronic checklist. - Page 11 Time Pressure The HUS has been laid out in a very similar fashion to the handset so it is very intuitive for existing users and there is no confusion when alternating between the two displays. The HUS uses high contrast colours to help highlight important information as well as the status of the rebreather.

All other information in this example are shown in white as they are all within the appropriate limits. In an attempt not to crowd the HUS display, it does not display max depth, current gas, any CCR and DECO menus or functions found by pressing and holding buttons. - Page 13 Time To Surface (TTS) Display When sufficient depth and time causes a decompression obligation, the handset and HUS show a time to surface (TTS) along with the dive time, current depth and a ceiling height that the diver should not exceed.
- Page 14 Estimated Time To Surface (EST) Display When the current depth has been shallower than the ceiling height for more than 2 minutes (a ceiling violation), the TTS will be replaced with an EST (estimated time to surface). 1.30 1.30 1.32 1.32 108:27 DIL3 10/70...

Page 15: Ceiling Height And Violation
Ceiling Height and Violation Ceiling Height Both the HUS and rebreather handset display ceiling height as a numerical value (either in metres or feet) However, the HUS also has a graphical representation for this on the left of the display.

Page 17: Ascent Rate
Ascent Rate The ascent rate is represented graphically on the right of the display. Ascent Rate When ascending at a rate of less than 5m/min the bar graph will be green. As the ascent rate increases the graphic extends higher and turns yellow when the ascent rate is between 5 and 10m/min. -

Page 19: Optional Connectivity
Optional Connectivity There are various options that can be used with AP diving rebreathers and these options are highlighted on the HUS as well as the handset. Scrubber Monitor Conditional Colouring The Scrubber Monitor is displayed in the same way as the handset but with the added benefit of conditional colouring. -

Page 22: Maintenance
Post dive, always store the rebreather lid in a clean dry environment and take care not to leave the lid and HUS exposed to high temperatures. Do not expose the HUS to disinfecting regimes. The HUS should be protected against shock at all times and avoid scratches on the lens by replacing the lens protector if it starts to peel. -
