Turning the camera on / Activating the
electronics / - the exposure metering system
The LEICA R9 is turned on and off using the
exposure mode dial (1.11). In the OFF position,
the camera electronics and all displays are
turned off to guard against accidental shutter
release and unnecessary power consumption.
Selecting one of the exposure modes switches
the camera into a ready mode (see also "Expo-
sure mode dial", p. 119).
Lightly pressing the shutter release button on the
camera (1.17), one of the two on the Motor-Drive
R8/R9, or on a remote control unit turns the
exposure metering system on. The LCDs in the
viewfinder, on the top panel (1.22) and the rear
panel (1.34) light up. If the shutter is cocked,
they remain on for 14 seconds after the release
button is let go; when the shutter is released
they go out immediately after the release button
is let go.
Notes:
The LEICA R9 requires the least power when turned
off, i.e. significantly less than even the ready
mode described above (after the displays are
extinguished). Therefore, you should make a
habit of always setting the dial to OFF if you will
not be using the camera for a long time. Ensure
that the rear panel is closed, otherwise the
camera will also consume more power.
Switching off the camera cancels any functions
that are in progress, such as long-time exposures
and mirror pre-release (see "Mirror pre-release",
p. 184). By contrast, self-timer mode (see "Self-
timer", p.183) is only interrupted.
When the camera is turned off, the frame coun-
ter on the top panel only goes out after a short
delay.
