DUAL TIME MODE

To Set the Dual Time Mode

•In Dual Time Mode, Press and Hold [ MODE ] for 2 seconds until the "minutes" digits flash

•Press [ MODE ] to navigate to the setting that you wish to change. See navigation chart at right

•When the setting you wish to change flashes, Press [ ST/STP ] to raise the value or [LAP/RESET] to lower the value.

Note: If you Press and Hold the button, the rate of change is faster

• When the hour is set, Press

[ MODE ] to confirm and return to the Dual Time Mode

NOTE: If NO INPUT for 1 minute during the setup, the display will default to the Dual Time Mode

on the continent. Where True and Magnetic North are in the same direction, the declination is zero. At any point west of that line, your compass needle will point east of True North. This is called “Easterly Declination.” At any point east of that zero line, your compass needle will point west of True North. This is called “Westerly Declination.”

NOTE: The watch displays Westerly Declination as a negative number. example: -45

MAGNETIC DECLINATION COMPENSATION

The watch will automatically make declination compensation. We have included a list of the declination angles of North America. In the Declination Setting Mode, input the closest angle and the watch will make the adjustment.

COMPASS MODE

This watch is a digital compass that provides directions, bearings and Magnetic North Pole location.

Caution: Accurate readings will be compromised when used near magnetic fields, mobile phones, speakers, motors, electrical appliances and inside a moving vehicle or a ferroconcrete building.

Watch may need to be calibrated for declination

Compass Standby Mode

•To extend battery life, watch will switch to standby mode if there is NO

COMPASS CALIBRATION

To Calibrate the Compass

• In the Compass Mode, Press

and Hold [ MODE ] for 2

seconds. DEC will display in

MAGNETIC DECLINATION

The Magnetic sensor in the compass is attracted by the magnetism of the Earth and therefore, always points to the constantly shifting Magnetic North. There is another “North Pole.” True North is static and located geographically about 800 miles north of the magnetic pole. Maps and directions usually are based on True North. Magnetic declination is the angle between True North and Magnetic North. The amount of declination at any given point depends on the location of that point.
