Compass
In compass mode, your RACING-TOUCH in-
dicates the magnetic North. By setting the	N
magnetic declination in the watch, it will
indicate True North.

Compass explanations

The vertical lines (meridians) on the Earth converge at the True North Pole (Ng),

indicating its direction. The hand of a conventional compass indicates the direc-
tion of the Magnetic North Pole (Nm). The angle
between these two directions Ng and Nm is known
as magnetic declination. The magnetic declination	Ng
value depends on your location on Earth. Fur-
	Nm
thermore, the Magnetic North Pole is constantly
moving. So the magnetic declination value also de-
pends on the date. If the correct magnetic declina-
tion value (for the location and date) is set (see the
setting procedure on page 11), the minutes hand
of your RACING-TOUCH will point to True North
(Ng). If the magnetic declination is set to 0, your

RACING-TOUCH will point to Magnetic North (Nm). The magnetic declination val- ues and dates are indicated on topographic charts, or can be found on the internet.

Azimuth

In compass mode, the LCD display of your RACING-TOUCH indicates the azimuth (heading or direction) that the watch (6-12 o’clock axis) is facing.

Azimuth explanations				Cap
An azimuth is the horizontal angle		Cap	N	N
between the direction of an object
(heading) and North and is measured
in degrees from 0° to 359° (e.g.: East
= 90°). In compass mode, 12 o’clock
represents the heading given by the	S	Azimut	S	Azimut
azimuth relative to North.		315o		315o
Example: Imagine you want to follow

a given azimuth of 315° East using your RACING-TOUCH. Activate the compass function and hold the watch horizontally in front of you. Rotate on yourself until you read the azimuth you are looking for (here 315°) in the LCD: the direction that both yourself and the watch are facing at that moment is the azimuth (here 315°) to follow.

Note 1

For a correct indication of North, it is very important to hold the watch as level as possible.

Note 2

The compass function, like any other compass, should not be used near a metal or magnetic mass. In case of doubt, you can recalibrate your compass.

ALARM

The 2 alarms are associated with time T1. An alarm rings during 30 seconds, without repeating. A ringing alarm can be stopped by pressing one of the push-buttons.
