LENS MOUNTING INSERTING BATTERIES

	1. Remove the rear lens and body caps. 2. Match the red dot on the camera body with the red dot on the lens. Insert the lens into the body and turn it clockwise until the lens locks with a click. 3. In the dark, when the red dots are difficult to see, align the upraised white dot on the lens barrel with the lens release lever by touch. Then turn and lock as above. 4. To detach, hold the camera with your left hand. Depress the lens release lever   while turning the lens counterclockwise with your right hand. www.4butkus.org
		CAUTION:  If you have to put the lens down without the rear lens cap, place place it front-element down never front element up.

BATTERIES

Two silver oxide batteries are packed separately. Be sure to insert them into the battery chamber before operating the camera. CAUTION:  The battery is like a phonograph record, it can be damaged by skin acids. Handle by the edges with a dry cloth before insertion into the camera. Also be especially sun to wipe off the battery with a cloth when they are salted. The battery is not rechargeable Do not throw a dead battery into a fire, as it may explode. Also keep it beyond the reach children.

INSERTION: Open the battery chamber cover with a coin. Insert the two batteries into the battery holder of the cover as shown above, each with (+) side facing up.

CHECK: One set of batteries will last about one year, or operate the shutter about 10,000 times. To check battery life, depress the shutter release button halfway, while looking through the viewfinder. If the batteries are dead, the LED dots will not glow. For replacement, use Eveready S76E or Mallory MS76H or equivalent.

BASIC OPERATING INSTRUCTIONS

1. Set Film Speed While depressing the tiny button atop the shutter dial, turn the rim of the shutter dial until the ASA number of the film you are using is centered in the ASA window. 2. Cock Rapid-Wind Lever Cock the rapid-wind lever all the way until it stops. The "Cocked" indicator will turn red, showing that the shutter is cocked. 3. Set Shutter Speed Turn the shutter speed dial until the speed you want to use is opposite the index mark. Generally, you should use the fastest possible shutter speed to avoid blurred pictures caused by camera movement. Try starting with 1/125 sec. outdoors in daylight and 1/30 sec. indoors. www.4butkus.org

 

4. Composing and Focusing While viewing through the finder, turn the focusing ring until your subject comes into sharp focus and choose the most pleasing composition. 5. Turn on Exposure Meter and Rotate Aperture Ring Pull out the rapid-wind lever slightly (20°) and depress the shutter release button halfway to turn on the exposure meter. The preselected shutter speed plus the two adjacent speeds ("60" and "250" in the case of "125") are visible on the right-hand side of the viewfinder. Turn the aperture ring until the central green LED dot glows which indicates proper exposure. (The f-stop you have selected is also visible in the small window above the focusing screen). If the central green dot does not glow no matter how far you turn the aperture ring, change the shutter speed. 6.Release Shutter Hold your camera firmly and trip the shutter. Then cock the rapid-wind lever for the next picture. (As long as the lever is at its pre-advance angle, the light meter stays ON. If you push it back to the completely closed position, the meter is turned OFF.)

FILM LOADING AND WINDING SETTING ASA FILM SPEED

1. Open the back by pulling up the rewind knob until the back opens.	2. Place the film cartridge in the film chamber, and push down the rewind knob. Insert the film leader in between any of the white plastic pins surrounding the film take-up spool.	3. Advance the film by alternately advancing the rapid wind lever and depressing the shutter button until both top and bottom sprockets engage the film perforations. Close the back by pressing it firmly.

4. Cock the rapid-wind lever, and confirm that the film rewind knob turns counterclockwise, indicating that the film is properly loaded and is moving from cartridge to take-up spool. Trip the shutter. Advance the film until the exposure counter turns to "1 ", indicating that the first picture is ready to be taken.

SETTING THE ASA FILM RANGE

MEMO HOLDER
As a reminder of the type of film in your camera, tear off the top of the film box and insert it into the Memo Holder on the back of the camera.	The ASA film speed rating of all 35mm films is given in the data sheet packed with each roll of film. The higher the ASA number, the more sensitive the film is to light. While depressing the ASA dial lock button, turn the rim   of the shutter dial until the ASA number of your film is aligned with the index mark. Be sure to set the ASA film speed because it is coupled to the exposure meter system. www.4butkus.org

SETTING THE SHUTTER SPEED DIAL COMPOSING AND FOCUSING

Turn the shutter speed dial clockwise or counter-clockwise to the shutter speed desired. The shutter speed may be set either before or after cocking the rapid-wind lever. As you cock the shutter by turning the rapid-wind lever, the "cocked" indicator turns red showing that the shutter is cocked. The color of the cocked indicator changes to black after tripping the shutter. For use of the X setting on the shutter speed dial, refer to page 18.  With the shutter speed dial set on B (bulb), the shutter will stay open as long as you depress the shutter button. As you release your finger from the shutter button, the shutter closes. When a long exposure is desired while using the 8 setting, set the shutter button lock by moving the lever to the left (an "L" becomes visible) while depressing the shutter button. Alternately, use a cable release with a locking device for a time exposure. CAUTION: At long speeds, longer than 1 /30 (1/15 - 1 sec.) support your camera rigidly to prevent camera movement. To protect the shutter mechanism, trip the shutter before putting the camera away for any extended period.

COMPOSING AND FOCUSING

The standard focusing screen of your MX has a central split-image circle surrounded by a microprism collar. While looking through the viewfinder, turn the focusing ring until your subject comes into sharp focus. If your subject is not in focus, the image in the split-image circle will appear divided into upper and lower portions, and the image in the microprism collar will appear broken into many small fragments.

EXPOSURE MEASUREMENT

When the rapid-wind lever is pulled out 20° and the shutter button is depressed halfway, the exposure meter is turned ON. Turn the aperture ring to get a proper LED exposure read-out in the viewfinder. On the right-hand side of the viewfinder, appear the preselected shutter speed plus two adjacent speeds (e.g. "60" and "250" in the case of "125") on a transparent disk which protrudes slightly into the focusing screen area. On the right-hand side of the shutter speeds shown, there are 5 LED dots which are normally not visible. If you depress the shutter button halfway and the exposure is correct, the central green dot will illuminate. If the exposure is 1 /2 EV over, the orange dot next to "250" (in the above example) will glow; as will the dot next to "60" in the case of 1 /2 EV underexposure. If it is 1 EV or more over or under, the appropriate red dot will glow as a warning for adjustment of either the f-stop or the shutter speed, unless you want to make intentional over or underexposure. As a general rule, your camera can be held more firmly in the left hand, which does not release the shutter. If you hold your camera with the right hand - the hand that releases the shutter - this may cause camera movement. Often, blurred pictures are due to camera movement. www.4butkus.org

HOLDING THE CAMERA

Horizontal position Hold the camera firmly with your left hand, and draw your arms close to your body	Vertical position Hold your camera tightly to your forehead with your left hand, and draw your right arm close to your body.	Vertical position Hold your camera tightly to your forehead with your left hand, raise your right arm and draw your left arm to your body.

UNLOADING FILM - AVOID DIRECT LIGHT WHEN UNLOADING THE FILM

After the final picture on the roll has been taken, the rapid-wind lever will not advance further, indicating that the film must be rewound. Lift up the rewind crank. Depress the film rewind button and turn the rewind crank as indicated to rewind the film into its cartridge. Rewind until the tension on the crank lessens, indicating that the leader end of the film has been released from the take-up spool. Pull out the film rewind knob (the back will open automatically), and remove the film cartridge.
