COMPASS
Compass, indication of geographical North
Description of the function
In COMPASS mode, your watchindicates the
geographical north pole, taking the magnetic
deviation into consideration.
Explanations
The vertical lines (meridians) on a globe converge toward
the geographical north pole (Ng) and indicate its direction.
The pointer on a conventional compass indicates the
direction of the magnetic north pole (Nm).
The angle (α) between these two directions is called the
magnetic deviation. The value of the magnetic deviation
therefore depends on your position on the globe.
Furthermore, the magnetic north pole is constantly
changing. The value of the magnetic deviation therefore
also depends on the date.
When the correct value (depending on place and date) of
the magnetic deviation is set (see the adjustment procedure
on page 12), the minute hand on your watch displays the
direction of the geographical North (Ng).
The values and dates of the magnetic deviation are
displayed on topographical maps or can be calculated
using special software.

Miscellaneous information
If you set the magnetic deviation to 0, your Khaki Field
Multi-touch will display the magnetic North (Nm).
The COMPASS function, as any other compass, must not
be used near a metal or magnetic object.
Thanks to its rotating glass, the watch can be oriented in
the same direction as a map. This glass is graded with the
following values:
- 30˚ between a cardinal point (N,E,W,S) and the closest
points.
It is very important that you hold the watch as horizontal as
possible to obtain a true indication of North.
