The FUNCTION-SELECTOR RING has three positions: "B" (for bulb), a lightning-flash
symbol (for using flash), and "AUTO. " At the "AUTO" position, the shutter-speed
control is fully automatic.
Selecting the diaphragm setting moves the diaphragm leaves to the desired f/ stop. At
the same time, the diaphragm-setting ring selects a value of resistance for the
exposure-control circuit. The shutter then automatically programs the shutter speed
according to the amount of light striking the CdS cell, the diaphragm setting, and the
film-speed setting.
The fastest speed the camera can deliver is 1/500 second. As you start depressing the
release button, watch the indicator lamps on the top cover. Lf the red (overexposure)
lamp comes on, you know that the fastest shutter speed of 1/500 second is too slow for
the proper exposure. You must then set a smaller f/stop.
If the yellow (slow) lamp comes on, the required shutter speed is too slow for a hand-
held exposure (slower than 1/30 second). The yellow-lamp warning tells you to use a
larger f/stop, a flash attachment, or a tripod.

You'll find the battery-test lamp in one of two positions, according to the camera model.
In current models, the battery-test lamp appears in the counter window when you depress
the battery-test button. Here, the battery-test lamp serves a second function -- it
illuminates the counter dial, making the calibrations visible at night. I.n earlier models,
the battery-test lamp is next to the battery-test button, Fig. 4.

Notice that the end of the release-switch rod moves toward the bottom of the camera as
you depress the release button. The release-switch latch then drops into a groove in
the release-switch rod -- that holds the release-switch rod in the depressed position
until you cock the shutter for the next exposure. This latching arrangement assures
that the exposure-control circuit remains connected -- even though you allow the release
button to return to its rest position.
Turning the screwdriver-slotted end of the release-switch rod controls the point at
which the release-switch latch drops into engagement. Check to see that the release-
switch latch engages the slot in the release-switch rod at the same moment that the
shutter releases. The adjustment may be disturbed when you replace the front plate
of the camera.

The battery-test lamp should turn on with 3. 9 volts supplied to the battery terminals; it
should turn off with 3. 5 volts supplied. Adjustment in the earlier models (figure 12) is
by changing the values of the fixed resistors; adjustment in the current models is by
scratching the surface of the printed resistors to increase the resistance.

You can reach the rangefinder infinity adjustment without removing the top cover plate.
Just lift the edge of the accessory-shoe cover plate that faces the front of the camera --
then, slide the accessory-shoe cover plate toward the back of the camera. You can now
see the clearance hole for the infiníty adjustment.

This adjustment changes the size of the opening between the two masks over the
photooell. The range of adjustment possible is around 1/3 f/stop.
