Asahi Pentax Motor Drive System
The Asahi Pentax Motor Drive System is the result of the painstaking efforts and
extensive research of the Asahi Pentax engineers who started working on this in'
strument in 1960. lt has been designed and constructed for further automation
and remote control of professional and advanced amateur photography. Retaining
the traditional ease of operation, precision, compact size and light weight of the
world-famous Asahi Pentax cameras, the Asahi Pentax Motor Drive System is ideally
suited for fast sequence photography, remote control photography, continuous copy'
ing, multiple simultaneous photography using two or more Spotmatic Motor Drive
cameras, and for many other industrial and scientific applications.

Exposure Gounter
According to the usual procedure of film
loading, load your film, and make two blank
exposures, making sure that the film re'
wind knob of the camera turns counter'
clockwise when you cock the rapid wind
lever. (This indicates that the film is be'
ing properly transported onto the take-up
spool.) With the tip of your finger, turn the
disk (27) in the base of the Motor Drive
Unit, and set the exposure counter (17) to
show the same number as the number of
the frames of the loaded film or the num'
ber of frames you wish to expose. The
exposure counter shows the n umber of
frames which remain unexposed; when the
counter reaches 0, the Motor Drive Unit Practice the oPeration as if You
will be switched off automatically. loaded a roll of film.
Shutter Release
To release the shutter, depress the trigger
button (10) of the battery grip after setting
the C/S switch either at C (consecutive) or
S (single). As you depress the trigger but'
ton with the C/S switch set at S, the Motor
Drive Unit releases the shutter; when you
leave your finger off the trigger button, the
Motor Drive Unit automatically cocks the
shutter and winds the film for the next
exposure. For operation at the position C
of the C/S switch, see page 10.
Film Rewind
After finishing all exposures, depress the
film rewind release button (18) of the Motor
Drive Unit, and start rewinding the film with
the rewind knob of the camera. As you
leave your finger off the rewind release
button (18), this button pops out; however,
the rewind release button of the camera
stays depressed until you cock the rapid
wind lever of the camera again. There'
fore, you do not have to keep depressing
the button (18).

into the side socket (30) of the battery
grip with its C/S dial set at C (also mean-
ing "check"). The battery still has op-
erating capacity if the checker needle
reads the black area marked "lO-L2."
lf the needle does not reach the black
area, replace or charge the battery.
Please do not keep the battery checker
plugged in for more than 10 seconds-
you will overheat the battery checker.
Battery Gharge
You can charge the NiCad battery without
removing it from the battery grip. Set the
C/S dial of the battery grip off at the green
dot, and screw the fastening knob into the
threaded hole of the charge pack. making
sure that the electrical contact of the battery
grip is properly inserted into the contact of
the charge pack. Plug the charge pack cord
into an AC main-turn the C/S dial to C (also
meaning "charge") -the pilot lamp of the
charge pack lights - the charge pack starts charging the battery.
The f ull charge time is about l4 hours. You
can keep charging the battery more than l4
hours without damaging it, but don't keep it
charged over 24 hours. The voltage of a fully
charged battery may exceed l2V; however,
this will do no harm to the Motor Drive Unit.
Usually, the minimum full charge/discharge
cycle of a NiCad battery of the type used for
this System is 100 times. You can use the
battery before it is fully charged, although
the operating speed of the Motor Drive Unit
will be slower than when the battery is fully
charged. Try to charge your battery at nor-
mal temperatures: not below freezing temp-
erature and not over 40'C (104'F).
