Frequency range : 15 Hz to 1 MHz and d.c. respectively
Note: Appropriate measures should be taken to obtain the correct value in case of non
sinusoidal waveforms.
The measuring instrument is calibrated by comparing the frequency factor of with the
solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is
constructed showing the deviation of from the ideal curve as a function of frequency.
TOUCH CURRENT = /500 (peak value).
The potential at any point (TOUCH CURRENT) expressed as voltage and
does not exceed the following value:
The part or contact of a TERMINAL is not HAZARDOUS LIVE if:
a) The open-circuit voltage should not exceed 35 V (peak) a.c. or 60 V d.c. or, if a) is not
met.
b) The measurement of the TOUCH CURRENT shall be carried out in accordance with
IEC 60990, with the measuring network described in Annex D of this standard.
The TOUCH CURRENT expressed as voltages and , does not exceed the
following values:
- for a.c. : = 35 V (peak) and = 0.35 V (peak);
- for d.c. : = 1.0 V
Note: The limit values of = 0.35 V (peak) for a.c. and = 1.0 V for d.c. correspond to
the values 0.7 mA (peak) a.c. and 2.0 mA d.c.

Product Safety Notice
Many electrical and mechanical parts in this chassis have special safety-related
characteristics. These characteristics are often passed unnoticed by a visual inspection and
the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement parts which have these
special safety characteristics are identified in this manual and its supplements; electrical
components having such features are identified by the international hazard symbols on the
schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The
use of substitute replacement parts which do not have the same safety characteristics as
specified in the parts list may create electrical shock, fire, or other hazards.

Handling the LCD Module
Safety Precaution
In the event that the screen is damaged or the liquid crystal (fluid) leaks, do not breathe in or
drink this fluid.
Also, never touch this fluid. Such actions could cause toxicity or skin irritation. If this fluid
skin or clothing, wipe off with alcohol, etc., and rinse thoroughly with water. If the fluid
should enter the eyes, immediately rinse the eyes thoroughly with running water.
Precautions for Handling the LCD Module
CAUTION: The metal edges of the LCD module are sharp, handle it with
care.
The LCD module can easily be damaged during disassembly or reassembly; therefore,
always observe the following precautions when handling the module.
1.
at the position where the display can be viewed most conveniently.
2. Carefully align the holes at all four corners of the LCD module with the corresponding
holes in the LCD cover and fasten with screws. Do not strongly push on the module
because any impact can adversely affect the performance. Also use caution when
handling the polarized screen because it can easily be damaged.
Page 21
3. If the panel surface becomes soiled, wipe with cotton or a soft cloth. If this does not
remove the soiling, breathe on the surface and then wipe again.
If the panel surface is extremely solied, use a CRT cleaner as a cleaner. Wipe off the
panel surface by drop the cleaner on the cloth. Do not drop the cleaner on the panel.
Pay attention not to scratch the panel surface.
4. Leaving water or other fluids on the panel screen for an extended period of time can
result in discoloration or stripes. Immediately remove any type of fluid from the screen.
5. Glass is used in the panel, so do not drop or strike with hard objects. Such actions can
damage the panel.
Page 22
6. CMOS-LSI circuitry is used in the LCD module, so avoid damage due to static
electricity. When handling the module, use a wrist ground or anchor ground.
7. Do not expose the LCD module to direct sunlight or strong ultraviolet rays for an
extended period of time.
8. Do not store the LCD module below the temperature conditions described in the
specifications. Failure to do so could result in freezing of the liquid crystal due to cold
air or loss of resilience or other damage.
9. Do not disassemble the LCD module. Such actions could result in improper operation.
Page 23
10. When transporting the LCD module, do not use packing containing epoxy resin
(amine) or silicon resin (alcohol or oxim). The gas generated by these materials can
cause loss of polarity.

SCHEMATIC DIAGRAM
Precaution
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY
RADIATION PRECAUTION" FOR DIRECT VIEW CTV ONLY, "SAFETY
PRECAUTION" AND "PRODUCT SAFETY NOTICE" OF THIS MANUAL.
CAUTION: The international hazard symbols "" in the schematic diagram
and the parts list designate components which have special characteristics
important for safety and should be replaced only with types identical to
those in the original circuit or specified in the parts list.
The mounting position of replacements is to be identical with originals.
Before replacing any of these components, read carefully the SAFETY
PRECAUTION and PRODUCT SAFETY NOTICE.
Do not degrade the safety of the receiver through improper servicing.
Note:
1. RESISTOR
Resistance is shown in ohm [K=1,000, M=1,000,000]. All resistors are 1/6 W and 5 %
tolerance carbon resistor, unless otherwise noted as the following marks.
1/2R : Metal or Metal oxide of 1/2 watt
1/2S : Carbon composition of 1/2 watt
1RF : Fuse resistor of 1 watt
10 W : Cement of 10 watt
K : ±10 %
G : ±2 %
F : ±1 %
2. CAPACITOR
Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in
µF, and the values more than 1 in pF.
All capacitors are ceramic 50 V, unless otherwise noted as the following marks.
Page 29
=
Electrolytic capacitor
= Mylar capacitor
3. The parts indicated with "" have special characteristics, and should be replaced with
identical parts only.
4. Voltages read with DIGITAL MULTI-METER from point indicated to chassis ground,
using a color bar signal with all controls at normal, line voltage at nominal AC volts.
5. Waveforms are taken receiving color bar signal with enough sensitivity.
6. Voltage reading shown are nominal values and may vary ±20 % except H.V.
PCB LAYOUT: Place all decoupling capacitors (0.1uf)as close to the pin
as possible.
