To maximize your enjoyment of the binoculars, please read these instructions on use and care before using them. 1. Adjusting the Interpupillary Distance (IPD) Since the distance between the eyes (specifically, the distance between the centers of the pupils) varies among individuals, the two eyepieces of the binoculars must be correctly aligned (adjusted). This is called adjusting the interpupillary distance. To adjust this distance, lift the binoculars up to your eyes (using both hands) and look through them at an object in the distance. Move the two halves of the binoculars about the hinge until you see one clear circle of image through both eyes. 2. Installing the Batteries Your binocular uses 2AAA batteries (user supplied). Open the battery door to install them. The battery door indicates the polarity that the batteries need to be in to operate properly. The ‘+’ indicator means that the battery must have the ‘+’ position facing you. If you have the polarity reversed, the zoom buttons will be reversed. Note: If you won’t be using your binocular for a long period of time, remove the batteries. 3. Adjusting Focus Since most people have a variance of vision from their left eye to their right eye, you must adjust the focusing system. Use the following steps to achieve focus: (1) Close your right eye and look through the left side of the binoculars with your left eye at the subject matter. Rotate the center focusing wheel until the image appears in sharp focus; (2) Close your left eye and look through the right eyepiece (called the diopter). Rotate the right eyepiece until the image appears in sharp focus; (3) Now look through both eyepieces with both eyes open. Since you’ve already adjusted the right eyepiece, use only the center focusing wheel to refocus on a new object at a different distance. Note: Use the diopter indicator and note the setting for later use for faster focus adjustment. 4. Power Zoom Adjustment Press the 8x button to begin observing and hold it down so it will rest at the 8x power. Note: An LED indicator light above the eyepiece will light up when pressing the button. The lowest power will give you the brightest image and widest field of view when observing. To view at a higher power, press the 24x button and hold it down until you reach the power you desire (anywhere from 9x to 24x). Note: An LED lamp will light up when using this button also. Higher powers are used to zoom in closer on the object you are viewing. When zooming to a higher power, you will have to refocus. To change back to a lower power, press down on the 8x button. Hint: Eyeglasses worn for nearsightedness should be worn when using binoculars as you may not be able to reach a sharp focus at infinity without them. 5. Set the Rubber Eyecups Leave the Rubber Eyecups up if you do not wear eyeglasses but fold them down if you do wear eyeglasses to obtain the maximum field of view. When done observing, fold the eyecups up for storage. Now you are ready to use your binoculars ---enjoy the view! Focus Wheel Battery Door Zoom Buttons Diopter Eyepiece 6. Care and Cleaning Binoculars do not need routine maintenance other than making sure that the objective lenses and eyepieces are kept clean. If repairs become necessary, they should be serviced by the manufacturer or a qualified binocular repair company. Collimation (optical alignment) is the biggest concern with binoculars. If your binoculars are roughly handled or dropped, there is a good chance that the collimation will be out and they should be serviced. Dirty objectives and/or eyepieces mean less light transmission and loss of brightness as well as unsharp images. Keep your optics clean! When not using your binoculars store them in the case provided. Avoid touching the glass surfaces but if fingerprints (which contain mild acid) get on them, they should be cleaned as soon as possible to avoid damaging the coatings. To clean the optical surfaces, we recommend a lens/optics cleaning kit available at most photo or optical shops and follow the instructions provided closely. If you have a lot of dust or dirt accumulated, brush it off gently with a camel’s hair brush and/or utilize a can of pressurized air before using the cleaning kit. Alternately, you could use the Celestron LensPen (# 93575) made especially for cleaning binoculars. Never attempt to clean your binoculars internally or try to take them apart! 7. Caution! Viewing the sun may cause permanent eye damage. Do not view the sun with your binoculars or even with the naked eye. 8. Problems or Repair If warranty problems arise or repairs are necessary, contact the Celestron customer service department if you live in the U.S.A. or Canada. If you live elsewhere, please contact the Celestron dealer you purchased the binoculars from or the Celestron distributor in your country (listings on the Celestron website). 9. Warranty Your binocular has the Celestron No Fault Limited Lifetime Warranty for U.S.A. and Canadian customers. For...
