1.
In order to disassemble and repair the
unit in question, be sure to disconnect the
power cord plug from the power outlet
before starting the work.
2.
If it is necessary to replace any parts, they should be replaced with respective genuine parts for the unit
,
and the replacement must be ef
fected in correct manner according to the instructions in the Service
Manual of the unit.
3.
After completion of repairs, the initial state should be
restored.
4.
Lead wires should be connected and laid as in the
initial state.
5.
Modification of the unit by the user himself should
absolutely be prohibited.
6.
T
ools and measuring instruments for use in repairs or inspection should be accurately calibrated in
Tools and measuring instruments for use in repairs or inspection should be accurately calibrated inT
advance.
7.
In installing the unit having been repaired, be careful to prevent the occurrence of any accident such as
electrical shock, leak of current, or bodily injury due to the drop of any part.
8.
T
o check the insulation of the unit, measure the insulation resistance between the power cord plug and
To check the insulation of the unit, measure the insulation resistance between the power cord plug andT
grounding terminal of the unit.
The insulation resistance should be 1M
Ω
or more as measured by a 500V DC megger
.
9.
The initial location of installation such as window
, floor or the other should be checked for being safe
enough to support the repaired unit again.
If it is found not so strong and safe, the unit should be installed at the initial location after reinforced
or
at a new location.
10.
Any inflammable object must not be placed
about the location of installation.
11
.
Check the grounding to see whether it is
proper or not, and if it is found improper
,
connect the grounding terminal to the earth.

WORKING ST
ANDARDS FOR PREVENTING BREAKAGE OF SEMICONDUCT
WORKING STANDARDS FOR PREVENTING BREAKAGE OF SEMICONDUCTWORKING ST
ORS
1. Scope
The standards provide for items to be generally observed in carrying and handling semiconductors in
relative manufactures during maintenance and handling thereof. (They apply the same to handling of
abnormal goods such as rejected goods being returned.)
2. Object parts
(1) Micro computer
(2) Integrated circuits (I.C.)
(3) Field ef
fective transistor (F
.E.T
.)
.E.T.).E.T
(4) P
.C. boards or the like to which the parts mentioned in (1) and (2) of this paragraph are equipped.
3. Items to be observed in handling
(1) Use a conductive container for carrying and storing of parts. (Even rejected goods should be handled in
the same way
.)
(2) When any part is handled uncovered (in counting, packing and the like), the handling person must
always use himself as a body earth. (Make yourself a body earth by passing one M ohm earth
resistance through a ring or bracelet.)
(3) Be careful not to touch the parts with your clothing when you hold a part even if a body earth is
being taken.
(4) Be sure to place a part on a metal plate with grounding.
(5) Be careful not to fail to turn of
f power when you repair the printed circuit board.
At the same time,
try to repair the printed circuit board on a grounded metal plate.

or higher) when ordinary iron is to be used.
(7) In checking circuits for maintenance, inspection, or some others, be careful not to have the test probes
of the measuring instrument shortcircuit a load circuit or the like.
