1. PRECAUTIONS
1-1 Safety Precautions
1) Before returning an instrument to the customer,
always make a safety check of the entire instrument,
including, but not limited to, the following items:
(1) Be sure that no built-in protective devices are
defective or have been defeated during servicing.
(1) Protective shields are provided to protect both
the technician and the customer. Correctly replace
all missing protective shields, including any
remove for servicing convenience.
(2) When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in
place all protective devices, including, but not
limited to, nonmetallic control knobs, insulating
fish papers, adjustment and compartment
covers/shields, and isolation resistor/capacitor
networks. Do not operate this instrument or permit
it to be operated without all protective devices
correctly installed and functioning.
AC Leakage Test
Any measurements not within the limits specified
herein indicate a potential shock hazard that must
be eliminated before returning the instrument to
the customer.
(4) Insulation Resistance Test Cold Check-(1) Unplug
the power supply cord and connect a jumper wore
between the two prongs of the plug. (2) Turn on
the power switch of the instrument. (3) Measure
the resistance with an ohmmeter between the
jumpered AC plug and all exposed metallic
cabinet parts on the instrument, such as
screwheads, antenna, control shafts, handle
brackets, etc. When an exposed metallic part has
a return path to the chassis, the reading should be
between 1 and 5.2 megohm. When there is no
return path to the chassis, the reading must be
infinite. If the reading is not within the limits
specified, there is the possibility of a shock hazard,
and the instrument must be re-pared and
rechecked before it is returned to the customer.
(2) Be sure that there are no cabinet opening through
which adults or children might be able to insert
their fingers and contact a hazardous voltage.
Such openings include, but are not limited to,
excessively wide cabinet ventilation slots, and an
improperly fitted and/or incorrectly secured
cabinet back cover.
(3) Leakage Current Hot Check-With the instrument
completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an
isolation transformer during this test.) Use a
leakage current tester or a metering system that
complies with American National Standards
institute (ANSI) C101.1 Leakage.
Current for Appliances and underwriters
Laboratories (UL) 1270 (40.7). With the
instrument’s AC switch first in the ON position and
then in the OFF position, measure from a known
earth ground (metal water pipe, conduit, etc.) to all
exposed metal parts of the instrument (antennas,
handle brackets, metal cabinets, screwheads,
metallic overlays, control shafts, etc.), especially
and exposed metal parts that offer an electrical
return path to the chassis.
Any current measured must not exceed 0.5mA.
Reverse the instrument power cord plug in the
outlet and repeat the test.
Insulation Resistance Test

5) Components, parts, and/or wiring that appear to
have overheated or that are otherwise damaged
should be replaced with components, parts and/or
wiring
that
meet
original
specifications.
Additionally determine the cause of overheating
and/or damage and, if necessary, take corrective
action to remove and potential safety hazard.
2) Read and comply with all caution and safety related
notes non or inside the cabinet, or on the chassis.
3) Design Alteration Warning-Do not alter of add to the
mechanical or electrical design of this instrument.
Design alterations and additions, including but not
limited to, circuit modifications and the addition of
items such as auxiliary audio output connections,
might alter the safety characteristics of this
instrument and create a hazard to the user. Any
design alterations or additions will make you, the
service, responsible for personal injury or property
damage resulting there from.
6)
4) Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:
(1) near sharp edges, (2) near thermally hot parts
(be sure that leads and components do not touch
thermally hot parts), (3) the AC supply, (4) high
voltage, and (5) antenna wiring. Always inspect in
all areas for pinched, out-of-place, or frayed wiring.
Do not change spacing between a component and
the printed-circuit board, Check the AC power
cord for damage.
Product Safety Notice-Some electrical and
mechanical parts have special safety-related
characteristics which are often not evident from
visual inspection, nor can the protection they give
necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc.
Parts that have special safety characteristics are
identified by shading, an (
) or a (
) on
schematics and parts lists. Use of a substitute
replacement that does not have the same safety
characteristics as the recommended replacement
part might created shock, fire and/or other
hazards. Product safety is under review
continuously and new instructions are issued
whenever appropriate.
1-2 Servicing Precautions
CAUTION: Before servicing Instruments covered by
this service manual and its supplements, read and
follow the Safety Precautions section of this manual.
(2)
Note: If unforeseen circument create conflict between
the following servicing precautions and any of the
safety precautions, always follow the safety
precautions. Remember; Safety First
(3)
1-2-1 General Serving Precautions
(1) a. Always unplug the instrument’s AC power cord
from the AC power source before (1) removing or
reinstalling any component, circuit board, module
or any other instrument assembly. (2)
disconnecting any instrument electrical plug or
other electrical connection. (3) connecting a test
substitute in parallel with an electrolytic capacitor
in the instrument.
b. Do not defeat any plug/socket B+ voltage
interlocks with which instruments covered by this
service manual might be equipped.
c. Do not apply AC power to this instrument and/or
any of its electrical assemblies unless all
solid-state device heat sinks are correctly
installed.
d. Always connect a test instrument’s ground lead

last.
Note: Refer to the Safety Precautions section
ground lead last.
The service precautions are indicated or printed on
the cabinet, chassis or components. When
servicing, follow the printed or indicated service
precautions and service materials.
The components used in the unit have a specified
flame resistance and dielectric strength.
When replacing components, use components
which have the same ratings, by ( ) or by ( )
in the circuit diagram are important for safety or
for the characteristics of the unit. Always replace
them with the exact replacement components.
An insulation tube or tape is sometimes used and
some components are raised above the printed
wiring board for safety. The internal wiring is
sometimes clamped to prevent contact with
heating components. Install such elements as
they were.
After servicing, always check that the removed
screws, components, and wiring have been
installed correctly and that the portion around the
serviced part has not been damaged and so on.
Further, check the insulation between the blades
of the attachment plus and accessible conductive
parts.
1-2-2 Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet and
turn the power ON. Connect the insulation resistance
meter (500V) to the blades of the attachment plug. The
insulation resistance between each blade of the
attachment plug and accessible conductive parts (see
note) should be more than 1 Megohm.
Note: Accessible conductive parts include metal
panels, input terminals, earphone jacks, etc.
1-3 ESD Precautions
Electrostatically Sensitive Devices (ESD)
Some solder removal devices not classified as
“anti-static” can generate electrical charges
sufficient to damage ESD devices.
Some semiconductor (solid static electricity) devices
can be damaged easily by static electricity.
Such
compo9nents
commonly
are
called
Electrostatically Sensitive Devices (ESD). Examples of
typical ESD devices are integrated circuits and some
field-effect transistors and semiconductor chip
components. The following techniques of component
damage caused by static electricity.
(5) Do not use freon-propelled chemicals. These can
generate electrical charges sufficient to damage
ESD devices.
(6) Do not remove a replacement ESD device from its
protective package until immediately before you
are ready to install it. (Most replacement ES
devices are packaged with leads electrically
shorted together by conductive foam, aluminum
foil or comparable conductive materials).
(1) immediately before handling any semiconductor
components or semiconductor-equipped assembly,
drain off any electrostatic charge on your body by
touching a known earth ground. Alternatively,
obtain and wear a commercially available
discharging wrist strap device, which should be
removed for potential shock reasons prior to
applying power to the unit under test.
(7) Immediately before removing the protective
materials from the leads of a replacement ES
device touch the protective material to the chassis
or circuit assembly into which the device will be
installed.
CAUTION: Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
(2) after removing an electrical assembly equipped
with ESD devices, place the assembly on a
conductive surface such as aluminum foil, to
prevent electrostatic charge buildup or exposure
of the assembly.
(8) Minimize
bodily
motions
when
handling
unpackaged
replacement
ESD
devices.
(Otherwise harmless motion such as the brushing
together of your clothes fabric or the lifting of your
foot from a carpeted floor can generate static
electricity sufficient to damage an ESD device).
(3) Use only a grounded-tip soldering iron to solder or
unsolder ESD device.
(4) Use only an anti-static solder removal devices.

FLASH MEMORY EN25B80
GENERAL DESCRIPTION
The EN25B80 is a 8M-bit (1024K-byte) Serial Flash memory, with advanced write protection mechanisms,
accessed by a high speed SPI-compatible bus. The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction.
The EN25B80 has twenty sectors including fifteen sectors of 64KB, one sector of 32KB, one sector of
16KB, one sector of 8KB and two sectors of 4KB. This device is designed to allow either single Sector at a
time or full chip erase operation. The EN25B80 can protect boot code stored in the small sectors for either bottom
or top boot configurations. The device can sustain a minimum of 100K program/erase cycles on each sector.
SIGNAL DESCRIPTION
-18-
Serial Data Input (DI)
The SPI Serial Data Input (DI) pin provides a means
for instructions, addresses and data to be serially
written to (shifted into) the device. Data is latched on
the rising edge of the Serial Clock (CLK) input pin.
Serial Data Output (DO)
The SPI Serial Data Output (DO) pin provides a means
for data and status to be serially read from (shifted out
of) the device. Data is shifted out on the falling edge of
the Serial Clock (CLK) input pin.
Serial Clock (CLK)
The SPI Serial Clock Input (CLK) pin provides the
timing for serial input and output operations. ("See SPI
Mode")
Chip Select (CS#)
The SPI Chip Select (CS#) pin enables and disables device operation. When CS# is high the device is deselected and
the Serial Data Output (DO) pin is at high impedance. When deselected, the devices power consumption will be at
standby levels unless an internal erase, program or status register cycle is in progress. When CS# is brought low the
device will be selected, power consumption will increase to active levels and instructions can be written to and data
read from the device. After power-up, CS# must transition from high to low before a new instruction will be accepted.
Hold (HOLD#)
The HOLD pin allows the device to be paused while it is actively selected. When HOLD is brought low, while CS# is
low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored (don’t care). The hold
function can be useful when multiple devices are sharing the same SPI signals.
Write Protect (WP#)
The Write Protect (WP#) pin can be used to prevent the Status Register from being written. Used in conjunction with
the Status Register’s Block Protect (BP0, BP1and BP2) bits and Status Register Protect (SRP) bits, a portion or the
entire memory array can be hardware protected.
MEMORY ORGANIZATION
The memory is organized as:
1,048,576 bytes
Flexible Sector Architecture
Two 4-Kbyte, one 8-Kbyte, one 16-Kbyte,one 32-Kbyte, and fifteen 64-Kbyte sectors
Bottom or top boot configurations
4096 pages (256 bytes each)
Each page can be individually programmed (bits are programmed from 1 to 0). The device is Sector or Bulk Erasable
but not Page Erasable.
