at
least
5 amperes.
SPEEDLAITP P'CTURES
Kodatron
Speedlamps
(or
similar equipment with
no
lag
in the trip circuit) can be used with this camera.
For these
light
sources, set the selector
on X;
connect
the cord from the
lamp to the
post
on the rim of the
shutter;
then follow the regular
picture-taking proce-
dure. The normal blade action
of
the shutter actuates
and synchronizes
the flash discharge ofthe speedlamps.
This
shutter
is not made for use with electronic
flash units which are flashed by means ofheavy-duty
relays or
solenoids. Such units
may
completely destroy
the shutter contacts.
