2-3. Adjustment of each section
A. Lens reference position adjustment
In this model, the reference value according to each lens charac- teristics must be entered. With this value, the lens home position is determined.
<Procedure>
(1)Execute simulation
• Perform the following key operation.

•Substitute the "O – L" value (variation in the distance be- tween the original and the lens) on the lens value label at- tached to position B shown in the figure below into the follow- ing formula, and input the obtained value.

<Example> When the lens value is +1.2;
50 – (1.2 ×5) = 44 (Correction reference value = input value)
<Check after adjustment>
Be sure to check that the magnification ratio cam is at the home position as shown in the figure below.
B. No. 4/5 mirror reference position adjustment
<Procedure>
(1)Remove the external fittings.
(2)Loosen two screws (A) which are fixing the No. 4/5 mirror and the No. 4/5 mirror drive holder to the No. 4/5 mirror holder.
