RACING-TOUCH N W E GLOSSARY > COMPASS S Compass In compass mode, your RACING-TOUCH in- dicates the magnetic North. By setting the magnetic declination in the watch, it will N indicate True North. S 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 value depends on your location on Earth. Furthermore, the Magnetic North Pole is constantly Ng Nm 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 explanations Cap An azimuth is the horizontal angle between the direction of an object Cap N N (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 azimuth relative to North. Azimut 315o S Example: Imagine you want to follow Azimut 315o 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. Characteristic of the function Accuracy: ± 8° Resolution: 2° 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. or 1 sec. or Activate glass Alarm 1 display SETTING > ALARM Alarm 2 display Alarm rings 2 sec. or Stop alarm or Alarm 1 or 2 display Activate or deactivate alarm Setting mode & : adjust alarm www.tissot.ch 12/13 Validate setting 151_EN
