HOW TO USE ELECTRONIC COMPASS FEATURE

Compass must be calibrated before first use.
Press

S1 to take compass reading. For accurate reading, make sure to level the

compass using the level bubble.
CAUTION: The Digital Compass function is very sensitive to magnetic and elec-

tric fields. The direction will be affected by nearby magnetic or electronic
devices.

CALIBRATION: Allows user to align the Compass magnetic sensor with the
earth’s magnetic field so that the Compass can detect the correct direction. With
the declination angle added, the magnetic North will be adjusted by the clock­wise shift or anti-clockwise shift of this angle, giving you the true North reading.
The range of declination angle is 00 E to 99 E and 00 W to 99 W. The declination
angles for major world cities are listed on the following page.

DECLINATION: The difference in degrees, or angle, between North and mag­netic North.

TRUE NORTH: Also, known as geographic North, this is map North (North Pole)
MAGNETIC NORTH: The geographical region toward which all magnetic nee-

dles point. This point is 1300 miles south of the North. (This is why it’s important
to calibrate!)

The declination angles for major world cities are included.

HOW TO CALIBRATE COMPASS

• Press S1 to enter compass mode, then press and hold S4, "CAL" will be dis-

played.

• Holding the unit on a flat surface, rotate the unit three times 360 degrees
clockwise, each rotation lasting between 10-15 seconds, then press

S4 to

end calibration.

• Set the flashing digits in 00 degree to the declination in your area (S2 is for
adjusting and

S3 is for selecting), after the setting is complete press S4 to

set.

• To exit to another mode, press S3.

TEMPERATURE MODE

You can toggle between F or C display. You can also offset the displayed temper­ature -+4 degree from the detected temperature. For example, if the
TerraTech/TrailDrop shows 77F (detected temperature) and another thermometer
shows 74F then you can set the TerraTech/TrailDrop to show 74F (displayed tem­perature), and from then onwards, displayed temperature is offset by

-3 degrees from the detected temperature.

• Press

S2 for 3 seconds to toggle between F or C display

HOW TO OFFSET TEMPERATURE

• Press S3 until "TE" displays.

• Press

S4 for 3 seconds to start the offsetting process; the digits start to

flash. Press
