and lightly press the shutter-

release button
... Pressing the shutter-release button lightly and
stopping it halfway is called a "Light press."
The power is turned on and the exposure meter
is activated when you pull the film-advance le-
ver out to the standoff position and lightly press
the shutter-release button.
• When the shutter-speed dial is set to the "B" position, the exposure meter is not
activated. Be sure to set the dial to another position.
• If the exposure-meter needle stops moving while the camera is being used, set the
shutter-speed dial to the "B" position first and then change to another position.
Make sure that the exposure-meter needle is moving.
• If you load non-DX-coded film with the film-speed index set to
loaded, the exposure-compensation indicator and the ready light blink alternately as a
warning. ( p.15)
Reference for battery replacement
1) Replace the battery (or batteries) at the earliest opportunity if the exposure-meter
needle moves only when you hold the shutter-release button pressed and then falls
down at once when you release it.
2) Replace the battery (or batteries) immediately if the shutter curtains do not open
and the mirror stays at the upper position disabling film advance or if there is no
change in the viewfinder indications when you press the shutter-release button with
the shutter-speed dial set to the "A" position.
... In this case, set the dial to a position other than the "A" position to restore the
original state.
