* When loading 220 roll film in the Film Back GS 220, do not mistake
the dotted line before the arrow-mark for the start-mark.
* For the use of film backs other than the 6 x 7 format, read the
instructions supplied with the film back.
I. The manual film winder is used to place the first frame into posi-
tion, when the film back is detached from the main body. The manual
film winder will not stop rotating, even when the film is in place for
the first frame, but should be rotated 2 or 3 times more, in order to
take up slack in the loaded film.

7. Film Speed Dial
Set the film sensitivity of the film loaded in the film back, when using
finders with a built-in exposure meter. To set the film speed, depress
the ASA/ISO film speed dial lock button and, at the same time, rotate
the ASA/ISO film speed dial and set the required film speed to the
index. The dial has click-stops at 1/3rd increments.
Exposure compensation up to ±3 stops is possible at 1/3rd incre-
ments. To set the required compensation, slide the exposure com-
pensation dial lock button in the arrow-indicated direction, then
rotate the exposure compensation dial, as required.
When compensation is not needed, simply set to "0" where it is
locked.
* There will be no effect on the exposure, no matter where the
ASA/ISO film speed dial and exposure compensation dial are set,
when a finder with a built-in exposure meter is not used.
