(l)Preparations for adjustments and items to be checked
1) Set up the light box so that the entire pattern is evenly lit. Set the colour temperature to 3200OK.
2) Use test patterns that are not dirty nor discoloured.
3) If the electrical circuitry gets in trouble, be sure to pinpoint the trouble spot with a measuring instrument and repair
or replace the defective part.

the specific addresses on the E2PROM (IC502 and the ROM on the lens unit).
1) To adjust the camera:
Press the “CONTINUE” key first and then the “CAM ADJ” key.
