l. 1. The AV Resistor Urit is the same unit as is used in the AV-1
but improvements in individual parts tolerances have made adjust-
ments unnecessary. (This is also true of present AV-1's.) But {if
either (4)-В or (4)-10 is changed or moved, perform the following
checks.
1.2. Check
The contact point of the brush (4)-8 should align with the
triangular mark (part of the printed pattern) to the right of the
resistor pattern. Adjust with screw (4)-10.

2. Main Mirror
2.1. The fully up position of the main mirror should be at 0 +0.2
mm with respect to the lower edge of the shock absorbing cushion
(11). (In other words, it should compress the cushion slightly).
If this 1s not properly adjusted, the mirror may not return pro
per ly or there may be a light leak.
2.2. Curtain Release Point
The 1st curtain release should be released when the mirror
1s at a point two to three mm below the lower edge of the foam
cushion (11).
2.3. Mirror Light Shield Closing
When looking through the film aper-
ture, the light shield should be comple-
tely closed at least 0.1mm before the
main mirror reaches the top of its tra-
vel. You can tell when the light shield
is completely closed when you can no
longer see reflections of the main
mirror through the slit between the main

Assembly and Disassembly Notes
1. These parts can be removed without removing either the TOp COVEr
or front panel parts.
2. It is not normally necessary to remove (22)-(27).
3. (15)-6 - 10 and (15)-11 - 13 may be removed without regard to
(15}-1 - 6, and (15)-1 - 10 respectively
Adjustment Notes
1. See section 11.4.2. for lower winding base adjustments.
2. Match charge cams |[p/¢(8)) and connecting lever (4) according to
the amount of mutual friction surface between tnem At least 1/2 of
the charge collar (5) should be in contact with the charge cam. If not
use washer (3) to increase th. overlap.
Adjustment Tolerances (See parts catarog
for adjusting sizes)
—
l. If an oversize (3.8mm or larger) is used when adjusring overcharge,
(See xection 11,4,5,), use the 049 size connecting lever. If the stan-
dard (3.7mn) or smaller collar is used use the 065 size lever. (This
is to prevent backlash.
2. (4)-1 is used to prevent friction between the 2nd curtain latch and
connecting leveyv during winding. There should be 0.2mm between them.
With the shutter wound, there should be space between the 2nd curcaln
charge spring and the lever collar (4)-1.
3. Collar (5) is for overcharge adjustment (See section 11.,4.5.).
A 0.2mm change in collar diameter results in a change of C.32mm in the
overcharge.
4. Charge Gear (7) affects the film perforation position. (See section
II.4.1) Note: Black screws indicate the 010 size gear.
>. Pawl (10)-3 is used to prevent backlash, Use the size which gives
the correct distance hetween the gear and pawl.
Wind and hold at the fully wound
position.
The pawl should not reach next

using a collimator with charts optically at infinity.

[sight source(s) which can provide a constant, con-
sistent, illumination even over the central 20cm of the
chart is necessary. We have found that modified 35mm
manual slide projectors are best, and that two projec-
tors give much more even illumination than a single
unit. If a single unit is used, it should be located as
close as possible to the optical axis as possible to
avoid uneven illumination.
A.C. flicker makes adjustment very difficult. Each pro-
jector should be modified to take a D.C. 12V, 24W bulb.

Lens extension
To accurately measure the lens extension, a piece of graph
paper should be taped around the lens on the focusing
scale. Since the front panel is upside-down, the most
convenient position ie not at the normal index, so a
new index is also desirable.
NEW FD 50mm 1:1.4 | ;
The lead (extension for one complete revolution) is
12.5mm or 0.03472mm per degree. This is equivalent to
0.0648mm lens extension per millimeter of revolution on
the circumference of the focusing ring with 0.2mm thick-
ness graph paper.
FD 50mm 1:1.4
The lead ‚extension for one complete revolution) is
12.0mm-cr 0.0333mr per degree. This is equivalent to
0.0590mm lens extension per millimeter of revolution on
the circumference of the focusing ring with u.2mm thick-
ness araph paper.
Finite Distance (2 Meter) Lens Extension
It is necessary to establish the exact position for
correct focus at 2 meters on the test standard lens if the
finite distance method is used.
The calculated extension for 2 meter focus is 1.39mm, but
because of variations between individual lenses, the
follwing procedure is recommended.
A. Select a known-good camera body (an average of
several is better), and remove the front panel,
В. Select a 50mm/1.4 lens that is accurately adjusted
for infinity focus.
C. Prepare the front panel®and lens as outlined in
section (11.3.7).
D. Adjust the lens so that VAl = VA3 at TP3. Mark the
extension of the lens at this point. This is the
“just focus"* correct 2 meter point for the test
standard lens.
* just focus: For lack of a better term, the
Japanese term "just focus" will be used to indicate
the correct "in focus” signal or condition of the OF
circuit.

4. 1- ZXZuF film or Tantalium capacitor (on probe)
Standard:
Comparative height g£ front, middle, and rear wave forms
Front and Rear waves should be within 2% of the height of the
middle waveform.
Adjustment : R101 , R103 (or -R1Q1l, R102)
(Depends on section 3.4)
Method:
This method is written assuming the resistor selected in section
3.4 was R102. If it was R103, substitute R103 for R102.
l. Mount-a 20 KOhm variable resistors adjusted to about 10 KOhm
in the R101 and R103 position 3.
2. Check the waveform of TP2 on Channel 1, adjust for "just
focus” and record the middle waveform voltage as V2.
-TP2
3. Adjust for best front focus and adjust
the variable resistor so- that V1 = V2,
Repeat the process for rear focus.
(Course adjustment OK)

4. Monitoring TP3 on Channel 2, care-
fully adjust the lens: wntil the VA2
signal is maximum, (If an A.C. light
source. is used, this adjustment is "pa
practically impossible because of
instability of the waveforms).
5. Adjust the illumination just above the y
AGC threshold (where VA2 changes suddenly). VAI VA? VAS
Then adjust the oscilloscope variable gain control sp VA2
is about seven divisions on the screen.
6. As 1n step 3 , adjust for best front focus and adjust VRI
80 VA2 = VAl. Adjust for best rear focus and repeat using
VR3 until МАЗ = VA2,
7. Remove and measure the variable resistors and replace them
with fixed resistors of the same value.

IN ESTABLISHING THE SPARE PARTS LIST, WE CONSIDER REPAIR DIFFICULTY, LABOR COST,
SPECIAL TOOL REQUIREMENTS AND INDIVIDUAL PARTS Vs. ASSEMBLED UNIT COST TO DETERMINE
IN WHICH FORM PARTS WILL BE STOCKED.

OVERRIDING REASON FOR STOCKING PRE—ASSEMBLED UNITS.
THE UNITS LISTED BELOW ARE STOCKED AS UNITS BECAUSE THEY REQUIRE TOOLS OR
