€ Referring to the calculator chart on the flash,
set the guide number. You can also obtain the
proper guide number by multiplying F/stop
number times distance, For example, if ASA 80
film is being used, set the film speed on the
calculator to ASA 80 and check the proper
F/stop number at a distance of 3m (10 ft.), If
the calculator dial on the flash shows f4.5, set
the guide number to 13,5 (4.5x3m) or 45 in
case of feet. If the exact guide number is not
indicated on the camera, use the closest number
toit
COMMENT: You can select F/stop manually
without using the flashmatic mechanism, if you
wish. In this case, please refer to the instruc-
tions on your flash unit,
