Carson AZ-725, JK-842, JD-822, MiniScout 7x18, Tracker 8x21 Instructions Manual

...
Congratulations on selecting your new Carson binoculars!
With reasonable care, your binoculars will provide you with years of enjoyment. In order to achieve optimum performance, please read the instructions carefully on the proper use and care of your binoculars.
Instructions for Care
Like any fine optical instrument, your binoculars should be given sensible care. Keep the lens covers (not included with some models) on the lenses when binoculars are not in use. Do not drop or violently jar your binoculars. This may cause the internal optical components of your binoculars to become misaligned resulting in a double image when looking through them. Non-waterproof models should not be exposed to excessive moisture.

Cleaning
Cleaning must be done safely and carefully to avoid scratching the lenses and permanently damaging your binoculars. Safe cleaning can be accomplished using a Carson LensPen™ lens cleaning device.
If you do not own a Carson LensPen™, please follow the procedure below:
1. Blow away any dust or debris on the lens (or use a soft lens brush).
2. To remove dirt, grease or fingerprints, clean with a soft cotton cloth rubbing in a circular motion. Use of a coarse cloth or unnecessary rubbing may scratch the lens surface and eventually cause
permanent damage.
3. For a more thorough cleaning, photographic type lens cleaning fluid may be used. Always apply the fluid to the cleaning cloth, never directly on the lens.
4. IMPORTANT: Never attempt to clean your binoculars internally or try to take it apart.
Basic Binocular Terminology
Binoculars are commonly identified using two sets of numbers. The most common size is 8x21mm. The “8” is the magnification, and “21” is the diameter of the objective lens in millimeters.
Magnification: Typically binoculars range from 5x to 12x power. A 5x binocular means that the image you see through the binocular is 5 times larger than it would be when viewed with the naked eye.

There are larger power binoculars available, and most higher power binoculars are usually the variable type, also known as zoom binoculars. A 20x –80x zoom binocular, for instance, has a magnification range
from 20to 80 power.
Objective lens: The objective lens (front lens) diameter is listed in millimeters. The larger the lens, the more light can enter the binocular and the brighter the image will be. However, binoculars with smaller
lenses are more compact and portable.
Field-of-View: (also known as FOV) is the total width of the viewing area through your binoculars from left to right. It is often measured in feet at 1,000 yards. For instance, if you see “358 ft @ 1000 yds”, that means an object that is 358’ wide and a thousand yards away will take up the entire viewing area of the binocular image you see. Sometimes this measurement is listed in degrees and is referred to as Angle of View, i.e. 8°
. To convert to feet, multiply the number of degrees by 52.5 and you will get the FOV.
Example: If Angle of View is 8°, Field of View is 8 x 52.5 = 420’ @ 1,000 yds.
Types of Binoculars
Fixed focus and zoom binoculars are alternatives to standard binoculars, which traditionally
offer magnification in one set power only, with a wheel or knob used to engage the focus mechanism.
Fixed focus binoculars cannot be adjusted and are usually fixed at an average distance for use in concerts, opera, or any situation in which variable focusing on objects is not required.
