It is a basic manual exposure camera similar to any needle match except you have to match the lights. The link to the Ultimate K-mount site only shows a CM-4 not the S model. The CM-4S has a self timer. The CM-4 does not have a self-timer. Thanks to Gene Poon for that information.

On-line Procedure of Shooting Installing the batteries
1. By using a coin, unlock the battery chamber cover by turning it counterclockwise
(Fig. 1).
2. Place two 1.5V Alkaline batteries (LR44, A76) or two 1.5V silver
oxide batteries (SR44, S76, G-13) with the minus bump ( - ) side touching the
battery cap
(Fig. 2).
3. Replace the battery chamber cover by turning fully clockwise (Fig.
3).
Test the batteries when;
- a new battery is installed
- the camera has not been used for a long period of time
- the camera is being used continuously for many hours.
To test the batteries, press the shutter release button slightly. If
the batteries are in good condition, one of three LED's located at the
left side of the viewfinder frame will illuminate (Fig. 4).
If a LED fails to illuminate, the batteries are too weak and need to
be replaced, they are incorrectly inserted, or the speed selector is set
to " B " position.
FILM LOADING
Your Chinon CM-4s camera can be used with any kind of 35mm film.
USING THE MEMO HOLDER
The Chinon CM-4s compact SLR camera has a built-in memo holder feature.
To utilize the memo holder feature, simply cut off the top of the film
box and insert it into the memo holder located on the back cover of your
camera. This will enable you to quickly and easily identify the type of
film and ASA speed used in the camera. Your calling card can also be inserted
in the memo holder (Fig. 10).
FRAME COUNTER
Your Chinon CM-4s is equipped with a frame counter which displays the
number of exposures made and resets automatically upon opening the camera
back. When the camera back is opened the counter shows " S " indicating
the start of the picture taking process. When a film is loaded according
to the procedure previously described, the counter displays " 1 " indicating
that the camera is ready for the first exposure.

ADVANCING THE FILM
Every time the film advance lever is turned the counter will proceed
one stop forward. The number 24 and 36 are colored in orange to warn the
end of commonly available films (Fig. 11).4.butkus.org
Make sure the film has been loaded properly. Operate the film advance
lever through a full stroke. When the film end is reached the film advance
lever may stop before the lever is fully turned. Do not force the lever.
Stop winding at once and rewind the film. Refer to "Unloading Exposed Film".
ASA / DIN SETTING
The ASA/DIN speed of the film is specified on the box or in the instruction
sheet packed with the film. Set the ASA/DIN speed by lifting up and rotating
the shutter speed dial to be appeared in the film speed window. Be sure
to check the ASA number whenever you put new film into the camera (Fig.
12).
SHUTTER SPEED SETTING
Rotate the shutter speed dial to the left or right to select a suitable
shutter speed from the band
The aperture is set in the usual way by rotating the lens diaphragm
ring until the desired F stop is set against the green index mark on the lens barrel. For further explanation see " Determining Correct Exposure"
(Fig. 14 & 15).

* F stop Selection: The following may be used as a guide to determine
the lens F stop when you are using the camera;
Sunny day outside: F/8 - F/16
Cloudy day outside: F/4 - F/5 ~
Inside (without flash): F/1.9 - F/2.8
FOCUSING
Your Chinon CM-4s has three built-in focusing aids.
This split image focusing is particularly helpful when the subject is
dominated by vertical lines. The microprism is also helpful. When it is
out of focus, the image on the microprism will be composed of collection
of asterisks (Fig. 17).
These sparkling asterisks will disappear when the focus is properly
set. You can double check the focus setting by the image

DETERMINING CORRECT EXPOSURE
Your Chinon CM-4s camera has a through The Lens (TTL) exposure metering
system. Also called an open aperture measuring system. To determine the
correct exposure, operate the film advance lever, observing the subject
through the viewfinder in the center of microprism area. Depress the shutter
release button until the exposure indicator lamp (LED) located on the left
side of the viewfinder frame illuminates (Fig. 19).4.butkus.org
Should the green lamp (LED) not illuminate, you must turn either the
shutter speed dial or the lens aperture ring until the green lamp illuminates.
By doing so, you will be assured of a correct exposure.
* The Exposure Indicator:
Your Chinon CM-4s camera has three exposure indicator lamps (LED) located
at the left side of the viewfinder frame. These three lamps control the
condition of exposure of the camera. The conditions of exposure can be
confirmed in the following three ways;
When rotating the shutter speed dial or the lens aperture ring, you
must operate them slowly since the exposure indicator lamps are very sensitive.
Generally you should select a shutter speed first then operate the lens
aperture ring until the proper exposure is obtained. A tripod should be
used for shutter speeds longer than 1/30 sec.
UNLOADING EXPOSED FILM
When the film in the camera is fully exposed, the film advance lever
will stop. Do not attempt to force the lever any further. Rewind the film
and replace with a new film. Push in the rewind button at the bottom of
the camera (Fig. 20).
Unfold the rewind crank of the rewind knob The rewind button on the bottom of the camera will pop out upon the
next advancement of the film advance lever.
Your exposed film should be processed without delay.
CONVENIENT FEATURES
Interchangeable lenses
To attach the lens, match the red dot on the camera body with red dot
on the lens (Fig. 24). Then insert the lens into the camera body and turn
it clockwise until the lens locks with a click.
It is advisable to use a flash when the exposure indicators detect that
the light level is too low, such as indoors, at night time, or in daylight
when the subject is too dark to provide adequate exposure.
Electronic flash units as well as conventional flash units using flash
bulbs may be utilized. Your CM-4s has a hot shoe (Accessory shoe with built-in
flash contact) for "X" synchronization (Fig. 25).
Electronic flash units having a foot with built-in contact may be used
without connection cord. As the hot shoe has "X" type synchronization it
can be used with electronic flash at 1/60 sec. or at slower shutter speeds
(Fig. 26).
The lens aperture is determined by the calculation table indicated on
the flash unit. Specially designed and developed automatic flash units
are available for your Chinon
CM-4s as optional accessories. This highly advanced electronic flash
system permits carefree flash photography for you. Look at the following
fantastic flash units by Chinon;

The center of the viewfinder is the split image with microprism collar
which is surrounded by ground glass. When the camera is in focus, the image
of these focusing aids become sharpest. While observing the subject through
the viewfinder, turn the lens focus ring until the upper and lower split image match up to form a uniform image (Fig. 16).
on the ground glass. You can also focus indirectly. Actually measure
or estimate the distance to the subject and set the lens focus ring to
the appropriate setting (Fig. 18).
A: is overexposed - either close the aperture or change
to a faster shutter speed
B: is properly exposed (correct)
C: is under exposed - either open the aperture or change to
a slower shutter speed but do not go below 1/60 of a second unless on a
tripod. (webmaster) Only if you have a very steady hand or hold the
camera on or against something solid you can try to shoot
with a 50, 35 or 28mm lens down to 1/15 of a second. Remember, with
a flash, ignore the exposure meter use the setting the flash requires)
is set at "B " position.
Your Chinon CM-4s camera is equipped with a Chinon bayonet mount which
accepts all interchangeable lenses with the universal bayonet mount.
To remove the lens from the camera body, depress and hold the lens lock
release lever on the camera body, turn the lens counterclockwise as far
as it will go, and lift it up from the body (Fig. 23).
