ADJUSTMENT SEQUENCE:

1. Auto speeds

Variable resistor A set: ASA 100, X1 compensation, f/8. With 2.8V

supplied to the battery compartment, the shutter should deliver the

following shutter speeds ath the indicated light levels:

EV12

1/60 second

EV16

1/1000 second

EV8

1/4 second

2. Meter Readout

EV 12 and 16

Adjust variable resistor B

EV8

Adjust variable resistor C

Later versions of the flex circuit board have only one meter readout

adjustment, Fig. 8.

3. Battery test

Adjust variable resistor D for proper operation. Later versions of

the flex circuit do not have the batery test adjustment. It is then

only necessary to make an operational check.

AVOID DISTURBING:

Variable resistor VR-E on the menory circuit board (not

accessible until the flex circuit has been removed). In some

versions of the flex circuit, VR-E is at the top of the camera.

DISASSEMBLY HIGHLIGHTS:

Control positions:

Speed selector

Auto

Film speed

Unimportant

Location of left-hand threads:

Winding lever cap screw

Winding lever retaining nut

Self-timer lever screw

Sequence:

1.

Bottom cover (Loose parts: cover for power winder terminals and

rewind button)

2.

Top cover (Remove black ring at top of speed selector; top cover

screw is then accessible through hole in speed selector)

3.

Unsolder film speed resistor wires (two yellow) from flex

circuit and from diaphragm resistor (if you're just removing the

flex circuit, unsolder only the film-speed resistor wire that

connects to the flex circuit)

4.

Film-speed resistor (not necessary if you're just removing the

flex circuit)

5.

Unsolder red wires from flex circuit

6.

screws holding hot shoe contact above eyepiece

7.

Screw and clip that hold down photocell circuit board

8.

Screw and circuit board retainer at rewind-side of camera

9.

Screw and washer holding LED display at wind-lever side
