COMPLIANCE TO STANDARDS

When any TV receptor component is substituted, it is necessary

to check the list of components in the Service Manual and all

of those marked with * or

must be replaced with original

spare SANYO parts.

WARNING! This TV set contains components that are

particularly sensitive to static electricity (ESD).

It is recommended that all due precaution be taken

handling integrated circuits and semiconductors.

NOTES:

1.- Resistor values are expressed in Ohm

K=1000, M=1000000.

2.- Capacitor values lower than 1 are expressed in uF and values

higher than 1 are expressed in pF.

3.- The information in this scheme is correct at the beginning of

the series; SANYO reserves the right to modify this in

accordance with on-going product improvement policy.

4.- The measurements of voltages and oscillograms were carried

out with a TV set tuned to channel-21, normal adjustments

and colour bar pattern.

NOTA DE CUMPLIMIENTO DE NORMAS

Cuando se sustituye cualquier componente del receptor TV hay

que consultar la lista de componentes del Manual de Servicio,

y todos los componentes que estén indicados con * o

deben

ser sustituidos por recambios originales SANYO.

ATENCIÓN este televisor contiene elementos especialmente

sensibles a la electricidad estática (ESD).

Recomendamos que se realice la manipulación de circuitos

integrados y semiconductores con las debidas precauciones.

NOTAS:

1.- Los valores de las resistencias están expresados en Ohm

K=1.000, M=1.000.000.

2.- Los valores de los condensadores menores de 1 están expresados

en uF, los valores mayores de 1 están expresados en pF.

3.- Toda la información de este esquema es correcta en el inicio de

la serie; SANYO se reserva el derecho de modificarlo para

mantener su política de mejora continua.

4.- Las medidas de tensiones y oscilogramas se han efectuado con

el TV sintonizado en el canal-21, ajustes normalizados e imagen

con carta de barras de color.

NOTA SUL RISPETO DELLE NORME

Quando si sosttituisce qualsiasi componente del recevitore TV si

deve consultare l'elenco dei componenti nel Manuale per la

Manutenzione. Tutti i componenti contrassengati con * o

devono essere sostituiti con ricambi originali SANYO.

ATTENZIONE! Questo televisore contiene elementi

specialmente sensibili all'elettricità statica (ESD).

Consigliamo di realizzare gli interventi sui circuiti

integrati e sui semiconduttori con le dovute precauzione.

NOTE:

1.- Tutti i valori delle resistenze sono in Ohm,

K=1.000, M=1.000.000.

2.- I valori de capacità indicati con un numero minori di 1 sono

in uF maggiori di 1 sono in pF.

3.- Tutte le informacioni di questo schema sono corrette

all'inizio della serie. Seguendo la propria politica di

continuo miglioramento dei propri prodotti, la SANYO si

riserva el diritto di apportare modifiche senza preavviso.

4.- Le miure di tensione e gli oscillogrami sono stati

effettuati con la TV sintonizzata sul canale 21, regolazioni

normalizzate e immagine del monoscopio.
