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 ohms 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.
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. 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 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'elettricitŕ 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 capacitŕ 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.
