How To Use

To ensure the maximum performance of the binoculars, you must first adjust them to your own visual acuity. This is achieved by adjusting the eyecups and interpupillary distance, setting the diopter, and adjusting the focus. The image visibility differs according to your physical condition, surrounding environment, and weather conditions.

1 Adjusting the eyecups

This binoculars features multi-step twist-up eyecups to provide proper eye relief for use with or without eyeglasses.

If you do not wear eyeglasses, extend the eyecups to the desired position by turning them counterclockwise.

If you wear eyeglasses, twist the eyecups down so that they sit flush with the ocular lens of the binoculars.

＊Set the eyecups at the best position for your eyes. The twist-up eyecups can be set at one of four multi-step positions.

2 Adjusting the interpupillary distance

The distance between the pupils of your eyes is known as interpupillary distance. To see a single image, the binoculars must be set so that the center of the ocular lenses are the same distance apart as your pupils.

To adjust the interpupillary distance, look through the binoculars at an object in the distance and move the two barrels closer to or farther away from each other until the two circular images become one.

*Do not apply excessive force to the binocular when adjusting the interpupillary distance.

3 Adjusting the diopter

To adjust for the difference of visual acuity between your right and left eyes, the diopter adjustment ring on the right barrel of the binoculars must be adjusted. Adjusting the diopter will provide you with a crisp sharp image every time you use your binoculars. The binoculars is equipped with a locking diopter ring to prevent accidental readjustment.

A. Left Eye Adjustment
Select a motionless object and cover the right objective lens with your hand. Look through the left ocular lens with your left eye and turn the focus knob until your left eye is focused on the object you have chosen.

B. Right Eye Adjustment
Unlock the diopter ring by slightly extending the twist-up eyecup and sliding the diopter ring towards the eyepiece (towards you). Cover the left objective lens with your hand and look through the right ocular lens with your right eye (use the same object used for left eye adjustment).

Turn the diopter ring until the image is in focus. Slide the diopter ring towards the objective lens (away from you) to lock into place.

Your binoculars are now set to your eyesight.

4 Focusing

To make focus adjustments, simply turn the focus knob while viewing through both barrels.
