Turn off by holding the button for 3 seconds while on command
column 1. The complete turn off sequence is:
1. Press once to enter 1st command column (TURN-OFF).
2. Hold for 3 seconds.

•
Turn off the HUD when not in use to save battery power.
•
The HUD will turn off by itself after 30 minutes of inactivity.
•
However, the HUD will not turn-off if the wet contacts detect the presence of water.
•
Ensure the wet contacts are dry before putting the HUD into storage.
5.3.7 Calibrate PPO2 Command
Perform the PPO2 calibration by holding the button for 3 seconds
while on command column 2.
Calibration of the HUD should take place immediately after cali-
brating the controller! It is recommended that the HUD and con-
troller always be calibrated at the same time!
The complete calibration sequence is:
1. Open the valve on the oxygen tank.
2. Open the mouthpiece (=CC mode).
3. Turn on the HUD.
4. Start the calibration sequence for the controller (Chapter 6.11).
5. Perform the following steps as quickly as possible, so that you can calibrate the HUD as soon as pos-
sible after completion of the controller calibration!
6. Press once to enter 1st command column (TURN-OFF).
7. Press again to advance to 2nd command column (CALIBRATE).
8. Hold for 3 seconds.
9. While holding, the 2nd column LEDs count up. They blink twice to confirm the command.
10. The green and yellow LED rows then count up to indicate the calibration is in progress.
11. Once the calibration completes, the HUD will return to the regular PPO2 display.
•
The HUD only calibrates at a PPO2 of 1.0 ata. This means it assumes pure oxygen is used for the calibra-
tion, and it is performed at sea-level.
