Canon EOS 650 - Manual (Page 9)

Automatic Film Speed Setting
The camera automatically sets
film speed by sensing the DX code
marked on the film cartridge.
(ISO 25-5000 according to DX
code standard)
1. The automatically-set film
speed will appear in the display
panel while the film advances
to the first usable frame.
2. When using film without a DX
code, set the speed manually
by following these steps: (ISO
6-6400).
1) Set the main switch to
either “A” or “ (co)
2) Open the switch cover, and
press both the blue and
yellow buttons at the same
time to display the ISO film
speed number.
3) Turn the electronic input
dial until your film speed
displays.
Once the buttons are de­
pressed, you can remove
your fingers because the
ISO display is held on for ap­
proximately eight seconds.
To clear this status within
eight seconds, press the
shooting mode selector.
The previously set film
speed appears and blinks in
the display panel to warn
you if the film speed has not
been set. Always be sure to
set the correct film speed,
because the warning stops
after film speed setting.
