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
particularly sensitive handling integrated circuits and semiconductors.
NOTES:
1.- Resistor values are expressed in Ohm K=1000, M=1000000.
K=1.000, M=1.000.000.
2.- Capacitor values lower than 1 are expressed in uF and values
higher than 1 are expressed in pF.
en uF, los valores mayores de 1 están expresados en pF.
3.- The information in this scheme is correct at the beginning of
the series; SANYO reserves the right to modify this in
la serie; SANYO se reserva el derecho de modificarlo para
accordance with on-going product improvement policy.
mantener su política de mejora continua.
4.- The measurements of voltages and oscillograms were carried
out with a TV set tuned to channel-21, normal adjustments
el TV sintonizado en el canal-21, ajustes normalizados e imagen
and colour bar pattern.

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.
