rectangular button on the top left side of the binocular. Red illumination allows the compass display to
be read even in low light, and power automatically turns off after one minute to prolong battery life. If the
display does not come on, or the illumination becomes dim, replace the batteries (see below).
COMPASS CALIBRATION PROCEDURE
This calibration procedure will ensure that the displayed readings are accurate for the area in which the
compass will be used. The calibration should be done outdoors if possible, and with the binocular kept
at least 7 feet away from any large metal objects. Facing due north is not required for calibration.
1) After any signicant change in your location since the last calibration
2) After changing the battery, especially if a different brand is used
3) If the binocular was in direct contact with a large metal object (for example a steel table) while
the power was on (note that the power automatically shuts off after one minute, so this should not
be common)
After turning on the compass by pressing the power button on the
top right side of the binocular, rotate the entire binocular clockwise or counter-clockwise once in a full
circle (360 degrees) along each of these three axes, in this order, returning to the starting position at
the end of each step (see the diagrams on the following page):
Step 1: Pitch (rotate 1 full cycle “end over end”, in a vertical plane up/down)
Step 2: Yaw (rotate 1 full cycle “spinning around”, in a horizontal plane left/right)
Step 3: (rotate 1 full cycle as shown along the binocular’s center hinge axis)
