Congratulations on the purchase of your new Sightron Binocular. Sightron makes several types of precision binoculars for varied uses. These instructions will help you achieve maximum performance regardless of the model you have chosen.
Interpupillary distance (IPD) is the distance from the center of one eye to the other. To set the distance correctly hold your binocular in the correct viewing position and move the barrel
until you see one circular field. Once you have achieved a perfect circular field note the IPD reading on your binocular for future quick adjustments.
Note: Compact binoculars do not have an IPD scale.
ADJUSTING YOUR EYECUPS
Sightron offers several types of eyecups depending on the model of binocular used. Adjusting your eyecups will allow people wearing glasses to achieve a full field of view that would otherwise be reduced. Please see the illustrations for proper eyecup adjustment on the various Sightron models.
FOCUSING YOUR BINOCULAR
All Sightron Binoculars are adjustable for individual eye focus. To adjust for your eyes close your right eye and focus your left eye using the center focus wheel. Once the left eye is in focus, close the left eye and turn the right diopter until the right eye is in focus. Both eyes are now in focus, rotate the center focus wheel to adjust the focus for objects near or far until clear.
BINOCULAR CARE AND CLEANING
If you have purchased a waterproof model (SII Waterproof Series, SII Big Sky or SIII Series) your binocular is waterproof and fog proof and will provide many years of trouble free service. Non-Waterproof models are not fog-proof or waterproof and should not be used in conditions where water or harsh conditions will cause them to fog. It is best to store all binoculars in a safe clean environment where they will be free from excessive knocks and hard vibrations. Never attempt to wipe mud or dirt from lenses as the grit will scratch the lenses and remove the lens coating from your binoculars. To clean use distilled alcohol or purchase a camera cleaning kit from your local department store. Never use a standard window cleaning solution as they will scratch the lenses. Never attempt to clean your binocular by removing lenses or disassembly.
CAUTION: Never attempt to view the sun with your binocular or the naked eye, permanent injury and loss of sight may occur.
