2.9 BACK-FOCUS ADJUSTMENT
This unit is shipped from the factory after its back-focus has been adjusted. Therefore, back-focus adjustment is usually unneces-
sary. It should be performed only when required, for example after replacing the lens assembly.
1) Attach the focus chart onto the INF adjust-
ment tool.
2) Set the iris to fully open.
3) Adjust the illumination of the light box so that
the signal level is between 0.57 and 0.64 Vp-
p (80 and 90 IRE).
4) Adjust the back-focus by referring to the in-
struction manual of the remote control soft-
ware (PLSC1210).
