Setting CCR Setpoints
You can configure the high and low partial pressure of oxygen (PO2) setpoints for closed-circuit rebreather
(CCR) dives.
1 Hold MENU.
2 Select Dive Setup > CCR Setpoints.
3 Select an option:
• To configure the lower PO2 setpoint, select Low Setpoint.
• To configure the upper PO2 setpoint, select High Setpoint.
4 Select Mode.
5 Select an option:
• To automatically change the setpoint based on your current depth, select Auto.
NOTE: For example, if you descend through the high setpoint depth or ascend through the low setpoint
depth, the PO2 threshold switches to the high or low setpoint, respectively. Automatic setpoint depths
must be at least 6.1 m (20 ft.) apart.
• To manually change setpoints during a dive, select Manual.
NOTE: If you manually change setpoints within 1.8 m (6 ft.) of an automatic switch depth, then automatic
setpoint switching is disabled until you are more than 1.8 m (6 ft.) above or below the automatic switch
depth. This prevents unintended setpoint switching.
6 Select PO2, and enter a value.
7 If necessary, select Depth, and enter a depth value for the automatic setpoint change.
