The hw HUD is actived by pressing the piezo button. The button has to pressed twice within one second to turn on the hw HUD. To turn off the device press the button again twice. The system will go to standby after a de- lay of five seconds.

Display The partial oxygen pressure is displayed via three dual color LEDs after successful calibration of the oxygen sensors. The LEDs are installed in an ultra compact device that can be mounted at every known CCR mouth piece without screws nor the necessity of glue.

IMPORTANT: ble is not in mint conditon! Calibration prior to each dive / each power on is not obligatory (the hw HUD stores the latest calibration values) but The usage of at least two independent recommened to check for broken sen- monitoring devices for ppO2 is obliga- sors.

The setup has to be accomplished by person that is licenced to handle elec- tronic installations. The hw HUD electronic box is equipped with an 1m 8-wire cable for combined connection of HUD and sensors to achieve the most reliable wiring. Four...
The HUD is digitally controlled by the four wires of the electronic box mentioned in the overview. The high flex cable out of the HUD has four wires only. The colors of the wire are identical to those of the cable from the electronic box.

Installation sequence 8. Connect up to three ppO2 sensors to the remaining four cables ( most likely special connectors are neces- sary). Please keep in mind that all pins marked minus (–) are connect- ed to the single grey cable from the electonic box.
Battery replacement NOTE: hw HUD runs on 3.6V AA batteries. IMPORTANT: 1,5V AA batteries can not be used. For battery replacement use a coin to open the lid. The lid closes easily. Do not tilt the lid while closing the battery com- partment.

Battery replacement A SAFT LS14500 AA 3,6Volt Battery is part Battery life depends on several factors of the hw HUD package and it should be i.e. Temperature, blink codes. As bench- replaced with the same battery by SAFT mark consider 200 hours with S8 version with AA dimensions and 3,6V.

Maintenance The hw HUD is build as a low mainte- nance unit with safety features like per- fect sealed electronics. Rinse the complete setup of HUD and electronic box after dive with fresh wa- ter. Be careful to avoid any water drops to enter the system.
