Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual
inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a
higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this
Service Manual. Electrical components having such features are identified by marking with a on the schematics and
the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety
characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create
shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.
For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies for,

How to discriminate the "TYPE" identifications in the manual
The parts and circuits are identified by "TYPE" in this manual to discriminate the differences between models. The
TYPE numbers are the same as the model numbers. The table below shows how to read the type identifications.
CAUTION (COLOR LCD)
LCD display; the liquid crystal display (LCD) panel is mode by highly precise technology.
More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear as colored
bright dots. This mode not indicate a fault as the LCD panel stretches the limits of current technology.
Be careful of the section painted in white on the electronic viewfinder circuit board as it generates a high voltage.
The primary source of X-ray radiation in this viewfinder is the picture tube. The tube used in this viewfinder is specially
constructed to limit X-ray radiation emission. For continued X-ray radiation protection, the replacement tube must be
same type as the original, Hitachi approved one.
