Safety instructions
—
Safety
regulations
demand
that
the
set
be
restored
to
its
original
condition
and
that
components
identical
with
the
original
types
be
used.
Safety components are marked by the symbol A
—
Ail
1Cs
and
many
other
semi-conductors
are
susceptible
to
electrostatic
discharges
(ESD).
Careless
handling
during
repair
may
reduce
life
drastically.
When
repairing,
make
sure
that
you
are
conneted
with
the
same
potential
as
the
mass
of
the
set
via
a
wrist
wrap
with
resistance.
Keep
components
and
tools
on
the
same
potential.
-A
set
to
be
repaired
should
always
be
connected
to
the
mains
via
a
suitable
isolating
transformer.
—
Never
replace
any
modules
or
any
other
parts
while
the
set
is
switched
on.
~
Use
plastic
instead
of
metal
alignment
tools.
This
in
order
to
prelude
short-circuit
or
to
prevent
a
specific
circuit
from
being
rendered
unstable.
Remarks
—
The
direct
voltages
and
oscillograms
ought
to
be
measured
relative to the set mass.
EXCEPTION
At
the
power
supply,
the
DC
voltages
and
the
oscillograms
at
the
primary
side
are
measured
to
LIVE
GND.
~
The
direct
voltages
and
oscillograms
mentioned
in
the
diagrams
ought
to
be
measured
with
a
colour
bar
signal
and
the
picture
carrier
at
503.25
MHz
(C25).
—
The
oscillograms

Avvertimenti
- Le prescrizioni di sicurezza richiedono che l'apparecchio sia
ricondotto alle condizioni originali e che siano usati ricambi
originali.
Componenti di sicurezza sono marcati con A
— Tutti gli IC e semiconduttori sono sensibili a scariche
elettrostatiche (ESD). Noncuranze durante la riparazione di
semiconduttori
possono
danneggiarli
o
condurre
ad
una
riduzione drastica della durata. Durante la riparazione
-
,
agsicurarsi
di
essere
collegati
allo
stesso
pdtenziale
attraverso
un
bracciale
di protezione
contro
scariche
elettrostatiche.
Inoitre
tenere
anche
tutti;
componenti
e
gli
attrezzi
a
questo
potenziale.
— Apparecchi da riparare bisogna collegarli sempre via un
trasformatore isolante (separatore) alla tensione normale.
~Non
scambiare
moduli
o
altri
componenti
quando
l’apparecchio
é
in
funzione.
— Per l'accordo usare soltanto attrezzi di plastica (non usare
attrezzi metallici). Cosi si evitano cortocircuiti e collegamenti
instabili.
Osservazioni
~
Misurare
le
tensioni
continue
e
gli
oscillogrammi
riferiendosi
alla
massa
dell’apparecchio.
ECCEZIONE
Le
tensioni
continue
e
gli
oscillogrammi
dall’alimentatore
sono
misurati
sulla
parte
primaria
contro
GND-Live.
~
Le
tensioni
continue
e
gli
oscillogrammi
indicati
negli
schemi
di
collegamento
devono
essere
misurati
secondo
le
condizioni
seguenti:
segnale
barre

(C25).
— Gli oscillogrammi e le tensioni continue sono misurati in
RECORD o PLAYBACK.
~ | componenti indicati nelle liste sono intercambiabili con quelli
nell’'apparecchio nonostante l’'eventuale denominazione di
modelli.
Avisos
- Las instrucciones de seguridad exigen que después de la
reparacion el aparato se encuentre en el estado original y que
las piezas de repuesto, utilizadas para la reparacién, sean
idénticas a las originales.
Los componentes de seguridad estan marcados con A
~ Todos los IC y semiconductores son sensibles a descargas
electrostaticas (ESD). Un tratamiento no conforme a las
instrucciones de semiconductores en caso de reparacion,
podria llevar a la destruccién de estos componentes, o a una
reduccion drastica de la duracion. Tenga cuidado de que, en
caso de reparacion, estar al mismo potencial que la masa del
aparato, por una pulsera con resistencia. Ponga todos los
componentes, herramientas y recursos al mismo potencial.
— Para reparar un aparato hay que conectarlo siempre a la
alimentacion a traves de un transformador de aislamiento.
-
Cuando
un
aparato
esta
en
marcha
no
pueden
ser
cambiados
médulos
u
otras
piezas
de

— Para los ajustes hay que utilizar exclusivamente herramientas
de plastico (nunca herramientas metalicas). Asi se evitaran
cortocircuitos y circuitos inestables.
Notas
— Hay que medir las tensiones continuas y los oscilogramas
contra la masa del aparato.
UITZONDERING:
Bij het netgedeelte zijn de gelijkspanningen en oscillogrammen
aan de primaire kant tegen Live GND gemeten.
~ Las tensiones continuas y los oscilogramas mencionados en
los esquemas tienen que ser medidos de manera siguiente:
