Using the M. 15V Ni-Cd Control Pack 1
Slide the shutter release lock but-
ton on the Control Pack to the unlock
position.
* The button is provided to lock the
shutter release on the Control Pack for
safety sake in general or when a relay
cord is used, etc.
Pull and turn the mode selector until
it clicks to either "SINGLE" or "SE-
QUENCE".
In either mode, available shutter speeds
are the same as those with the Control
Grip. (See page 24, middle column.)
You may use either the shutter re-
lease on the Control Pack 1 or the shut-
ter release on the Motor Drive 1 to trig-
ger the shutter. It is generally conven-
ient to use the shutter release on the
Motor Drive 1 and the shutter release on
the Control Pack 1 for use with the 250
Film Back 1.

Loading the Film
Always try to load your camera after
the motor drive has been attached.
This eliminates even the remotest pos-
sibility of light leak through the motor
drive socket. If this is not possible,
attach the Motor Drive unit in a dimly-
lit area.
