Setting Ccr Setpoints; Air Integration; Installation And Setup - Garmin DESCENT MK2I Owner's Manual

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.

Air Integration

The Descent Mk2i dive computer can be used with a paired Descent T1 transmitter to view tank pressure,
estimated air time remaining, and estimated gas consumption. You can also view the tank pressure and battery
status for up to four other divers in your group.

Installation and Setup

To ensure proper setup and best performance, it is strongly recommended that you complete the first time
installation and setup at a dive shop. You should fully test the transmitter installation above and below water
before using it during a dive.
