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).

Before using the compass for the first time, it is necessary to calibrate the compass, using the following procedure:

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.

For best results, the compass should be calibrated again:

1)After any significant 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)

TO CALIBRATE THE COMPASS: 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: Roll (rotate 1 full cycle as shown along the binocular’s center hinge axis)
