Notes:
1 The old type of the Panel Chassis Assys was mounted in about the first 1090 units produced.
(As for PRO-FHD1, the old type of the Panel Chassis Assys was mounted in about the first 10 units produced.)
2 Either the old or new type of the SCAN Assy can be attached to a Panel Chassis Assy of the old type.
However, be careful of the following:
• When the old type of the SCAN Assy (50FHD SCAN A Assy: AWW1129, 50FHD SCAN B Assy: AWW1130) is used,
a ground wire with resistance is attached. After replacing the SCAN A/B Assy, be sure to secure the ground wire with
resistance as it was originally. (Be careful not to mix up the washers.)
• When the new type of the SCAN Assy (50FHD SCAN A Assy: AWW1229, 50FHD SCAN B Assy: AWW1230) is used,
a ground wire with resistance is not attached. Attaching a ground wire with resistance is not required after
replacement of the SCAN Assy.
