OVERVIEW
> S (2 sec) - to access Compass OP (operating) Main from Surface or Dive Main.
> S (2 sec), or no button action (2 min*) - to revert to Surface or Dive Main.
*During the final 15 seconds, the remaining On time is displayed. If a button is pressed during that time, the 2 minute On time will reset
allowing operation to remain in Compass Mode.
> Compass OP (operating) Mode selected (North or Reference) - remains until changed.
> Reference OP Mode - can set a course, then also select a Reverse course while on the surface and during dives.
> Numeric values are displayed as 3 digits (000 to 360°), have a resolution of 001°, and an accuracy of +/- 005°.
> Operation will be normal and display of values will be within specified tolerances up to 90° tilt at which time the Heading
(diver's direction) digits are removed until the tilt angle is corrected.
Upon accessing the Compass, the OP (operating) Main of the last mode selected will be displayed >> North, Reference, or
Reverse Reference.
While on the surface, press M (< 2 sec) to access the Compass Menu to change the OP Mode, Calibrate, or set Declination.

• A (< 2 sec) - to step forward (down) through selections.
• M (< 2 sec) - to step back (up) through selections
• S (< 2 sec) - to select the item highlighted.
If NORTH or REFERENCE MODE is selected, that mode will be saved and its Operating Main will be displayed.
• M (2 sec), any time - to revert to Compass OP Main.
• No button action (2 min) - to revert to Surface or Dive Main.
NORTH OP MAIN, information includes (Fig. 85A) -
> BATT icon - green (if battery voltage is good), or yellow (if at warning level), or red (if at alarm level).
> Current Depth with FT (or M) icon; or Surface Interval time (hr:min) with SURF icon when on the surface.
> Static Arrow (green, at 12 o'clock), actual direction of travel.
> Current dynamic compass (diver) heading (graphic (N, E, SE, etc.).
> Current (actual) numeric heading value with degrees ° icon. Removed when tilt exceeds 90°.
> North Mode icon (letter N in box).
> On time remaining with SEC icon, counting down from15 to 0 (seconds), blank when > 15 seconds remain.
> VARI (AR), while ascending.
• A (2 sec) - to access Adjust Brightness. As previously described.
• S (2 sec), or no button action during 2 min - to revert to Surface or Dive Main.
• S (< 2 sec) - to restore screen Brightness from the Auto Dim level to the % level you last adjusted it to.
• S (< 2 sec) - to acknowledge alarms; this will also restore screen Brightness if it was dimmed by Auto Dim.
• M (< 2 sec) - to access Compass Menu, surface only.
• M (< 2 sec), while in NORM Dive Mode only - to apply a snapshot Earmark to the PCI data recorded at that time. The
graphics EARMARK APPLIED will be displayed in place of the Compass for 3 seconds (Fig. 85B).
REfERENCE OP MAIN, information includes (Fig. 86) -
> BATT icon - green (if battery voltage is good), or yellow (if at warning level), or red (if at alarm level).
> Current Depth with FT (or M) icon; or Surface Interval time (hr:min) with SURF icon when on the surface.
> Turn Arrow (yellow), when actual heading deviates => 10° from the reference course set.
> Static Arrow (green, at 12 o'clock), actual direction of travel.
> Current dynamic compass (diver) heading (graphic (N, E, SE, etc.).
> Current (actual) numeric heading value with degrees ° icon. Removed when tilt exceeds 90°.
> Reference Mode icon (2 bars with arrow) with numeric course set below it, and green dot showing the course set.
> On time remaining with SEC icon, counting down from15 to 0 (seconds), blank when > 15 seconds remain.
> VARI (AR), while ascending.
