User manual ORION TELESCOPES & BINOCULARS ULTVWBINO

[. . . ] Severe and permanent eye damage could result. On sunny days, children should use binoculars only with adult supervision. Adjusting for the Distance Between Your Eyes The distance between the eyepiece lenses of the binocular should be adjusted to match the distance between your eyes, called the "interpupillary distance. " To adjust the binocular, hold each barrel firmly; move them together or apart while looking through the binocular with both eyes until you see a single, round field. Make this adjustment before focusing. Focusing UltraViewTM binoculars feature a convenient center focusing knob. However, because your eyes may differ slightly in their focus, the UltraViewTM also includes a right eye diopter adjustment. [. . . ] With the eyeguards retracted (down), your eyes can be positioned closer to the eyepiece lenses for an improved field of view. Mounting Your Binoculars on a Tripod For steadier or extended viewing, you can mount your UltraViewTM binocular on any standard camera tripod by means of an optional "L"-bracket (available from most binocular dealers). Unscrew the small cap bearing the white tripod symbol located at the front of the center shaft, between the two binocular barrels. Removing this cap reveals a 1/4"-20 threaded hole into which the top end of the L-bracket is inserted. The bottom end of the L-bracket is threaded onto the tripod itself. Cleaning and Care Although your UltraViewTM binocular is rubber covered, it is not waterproof!The lens surfaces of your binoculars are vacuum-covered with antireflection coatings that can be damaged with careless handling. Avoid touching lens surfaces with your fingers or any course material. Clean the lenses about twice a year, and more frequently if they get dirty. The dust that builds up on them promotes mold growth, which etches the glass and destroys the coatings. Always use lens cleaning tissue and fluid designed specifically for multi-coated lenses. Do not use tissue or fluids made for eyeglass or household use. To clean the binoculars, first puff air on the lens with a blower bulb or with compressed air to remove the larger particles. Then it's a good idea to brush the lens with a soft lens brush. Next, put two drops of lens cleaning fluid on a sheet of lens tissue (never directly on the lens). Wipe the lens gently in a circular motion, taking care to avoid undue pressure or rubbing. Quickly remove the excess fluid with a clean, dry lens tissue. On larger lenses, clean only a small area at a time, using a fresh lens tissue on each area. If dirt accumulates on an interior lens surface, do not attempt to disassemble the housing and clean the lens yourself. Take the binocular to a qualified optical repair technician. Storage and Cold Weather All optics, when exposed to excessive temperature changes or high humidity, have the potential to fog up.
