The menu options are the same for the down setpoint switch�
Example: Up: 0�7>1�3 = Auto, Up Depth = 70 ft�
Down: 1�3>0�7 = Auto, Down Depth = 41ft
The dives starts at the 0�7 setpoint� As you
descend
past
70ft, the setpoint switches “up” to 1�3�
You finish your bottom time, then begin ascending. When
you
ascend
above 41ft, it switches “down” to 0�7�
When a switch is set to “Auto”, you can always manually override
the setting at any time during the dive�
Each auto setpoint switch can occur only once per dive�
Either switch can be set to auto or manual independent of the other
switch�
The values 0�7 and 1�3 are shown as examples only� Other values
for the low and high setpoint can be adjusted in the Dive Setup
menu�
Display Setup
Units
Two options are available:
• Feet: Imperial units (depth in feet, temperature in °F)
• Meters: Metric units (depth in meters, temperature in °C)
Brightness
Screen brightness can be set to fixed levels or an automatic setting.
Fixed options:
• Low: Longest battery life�
• Med: Best mix of battery life and readability�
• High: Easiest readability, especially in bright sunlight�
The “Auto” option measures ambient light levels and then adjusts
the screen brightness to best performance� It provides maximum
brightness in bright sunlight, but then lowers brightess to save
battery life when the environment gets darker�
