ENGLISH
CAUTION(COLOUR LCD
LCD display; the liquid crystal display (LCD) panel is made by highly precise technology.
More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear as coloured bright
dots. This does not indicate a fault as the LCD panel stretches the limits of current technology.
CAUTION(CRT EVF
Be careful of the section painted in white on the electronic viewfinder circuit board as it generates a high voltage.
PRODUCT SAFETY NOTICE
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, HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES
CORPORATION.
X-RAY RADIATION
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.
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.
TYPE identification Model name
TYPE 230 rS VM-E230E
TYPE 338 = VM-E338E(SW)
VM-E438E(SW)
li Contents of This Service Manual
The VM-E230E is a minor revision model of the previous series model VM-E220E. The VM-E338E/VM-E438E is a minor
revision model of the previous series model VM-E228E.
This service manual includes only the differences from the VM-E220E/E228E.
Note on schematic diagrams
This service manual includes only the differences from the VM-E220E/E228E in the form of extracts.
For circuits not included in this manual, refer to the schematic diagrams identified as TYPE220 for VM-E230E or as
TYPE228 for VM-E338E/VM-E438E in the VM-E120E/E220E/E228E/E420E/H520E/H620E manual (No. 6606E).
