OCS OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5272-r01 (9/28/11)
Set Reference Heading, information includes (Fig. 151) -
> Current Depth with FT (or M) icon, blank on surface.
> Reference Mode icon (2 bars with arrow) with graphic SET (flashing) above it.
> Static Arrow icon (at 12 o'clock), diver direction of travel.
> Dynamic Arrow, tracking Reference direction currently set.
> Numeric heading (diver's direction) at lower/right, with position graphic.
> On time remaining, counting down, if 15 to 0 (sec).
• S (< 2 sec) - to flash Heading value (lower/right), with SET solid.
• Rotate the Compass (keeping level) in either direction to new Heading, at lower/right.
• S (< 2 sec) - to lock in new Heading, replacing SET.
Reverse Ref Heading, information includes (Fig. 152) -
> Current Depth with FT (or M) icon, blank on surface.
> Reverse Mode icon (2 bars with arrow) with reverse Heading (180° opposite of Reference Heading set) above it, flashing.
> Static Arrow icon (at 12 o'clock), diver direction of travel.
> Dynamic Arrow, tracking Reference direction currently set.
> Numeric heading (diver's direction) at lower/right, with position graphic.
> On time remaining, counting down, if 15 to 0 (sec).
• S (< 2 sec) - to reverse Heading.
The value above the Reverse Mode icon (new course) will stop flashing indicating the Heading has been reversed.
The value at the lower/right will then indicate actual current direction.
CALIBRATION (surface only)
Local magnetic fields can effect display of actual location when reading a digital compass. It may be advantageous to Cali-
brate the Compass before its first use after purchase, use in new regions, or if inaccuracies are experienced. Calibration will be
required when the battery is changed.
CAL Access/Start**, information includes (Fig. 153) -
> Graphics CAL and ROTATE.
> 360 with ° icon.
• S (< 2 sec) - to activate (start) Calibration.
• Slowly and steadily rotate the unit 360° in either direction while maintaining it in a flat level position (keeping it level is
critical for acurracy), CAL progress will be displayed.
** The CAL ROTATE screen will also be accessed after the Battery is changed and Data is either saved or cleared.
CAL Progress**, information includes (Fig. 154) -
> Graphic CAL.
> dotted circle, increasing from 0 to 360° as it is rotated.
**Rotation should take about 30 seconds. If not fully rotated in 60 seconds, operation will revert to the Menu.
CAL Complete,
information includes (Fig. 155, 156) -
> Graphic CAL.
> Graphic READY or AGAIN, flashing for 3 seconds.
* READY, means it passed, in which case Calibration is complete and operation reverts to the OP Main.
* AGAIN, means it failed**, in which case the CAL ROTATE screen will be displayed. Press S (< 2 sec) to repeat Calibration.
**If Calibration fails after 3 attempts, operation will revert to the Watch or Surface Main from which it was accessed. If you
then continue operation, the previous successful Calibration will remain in effect.
DECLINATION
Magnetic Declination is taken from numbers provided on maps or charts that apply to a specific location. The numbers represent
the easterly or westerly angular difference (Declination) in degrees between magnetic North and true (geometric or polar) North.
A Compass will point to magnetic North unless its reference is adjusted to true North prior to conducting activities.
Declination Menu, information includes (Fig. 157) -
> Graphic SEt, with selections -
> DECLIN OFF.
> DECLIN EAST.
> DECLIN WEST.
• A (< 2 sec) - to step forward (down) through Menu selections.
• M (< 2 sec) - to step back (up) through Menu selections.
• S (< 2 sec), when the pointer icon ( > ) is next a selection - to select it.
