DISPOSICIONES PARA LA SEGURIDAD
Después de operaciones de servicio en aparatos de la clase de
proteccion Il, se llevara a cabo la medida de la resistencia de
aislamiento y de la corriente derivada, con el aparato conectado, de
acuerdo con VDE 0701 o de las disposiciones vigentes en el lugar de
instalaci6n .
|
Este aparato corresponde a la clase de proteccion Il, reconocible por
el simbolo [G] .
@ Medida de la resistencia de aisiamiento segin VDE 0701.
Aplicar el medidor de aislamiento (U 4, = 500 V-), simultanea-
mente, a los dos polos de red y entre todas las partes del mueble
o de funciones ( antena, conectores, teclas, tornillos, etc.) de matal
0 aleaciones metdlicas. El aparato estara libre de defectos con:

Tiempo de medida 2 1 seg.
Observacién: En aparatos de la clase de proteccién II, condicionado
por la construccién y por resistencias de descarga, el valor de medida
de la resistencia de aislamiento puede ser superior a < 2 MQ.
En este caso es decisiva la medida de la corriente derivada (Fig. 1).
@ Medida de la corriente derivada de acuerdo con VDE 0701.
Aplicar el medidor de corriente derivada (U | 44, = 220 V=) simul-
taneamente a los dos polos de red y entre todas las partes del
mueble o de funciones (antena, conectores, teclas, tornillos, etc.)
de matal o aleaciones metalicas. El aparato estara libre de defectos
con (Fig.2):

@ Aconsejamos llevar.a cabo las medidas con el METRATESTER 3
(Instrumento de medida para la comprobaci6n de aparatos eléctri-
cos segtin VDE 0701).

®@ Si no se cumple la seguridad del aparato, poroue
-
la puesta en orden es imposible, o
-
esiste el desco del usuario de no realizarla, se ha de comunicar
a quien lo haga funcionar, por escrito, del peligro dimanante del
aparato.
Recomendaciones para caso de servicio
e Emplear sdlo componentes originales. |
Con componentes o grupos constructivos con el indicative de se
guridad /A\ son de obligada necesidad piezas de repuesto origina-
les.
@ Las vartes del aparato que contribuyan a la seguridad del mismo no
deben estar deterioradas ni ser manifiestamente inadecuadas.
@ Esto es especialmente valido para aislamientos 0 piezas aisiantes.
@ Los cables de red y de conexidn se comprobaran, antes de concc
tarlos, en cuanto a defectos externos. Comprobar el aislamiento.
@ Se ha de comprobar la funcién de seguridad de la compensacién
de tiro o de los manguitos de proteccién contra doblamientos.
@ Repasar los puntos de soidadura sometidos a carga térmica.
@ Mantener libres los canales aireacion.

Safety Instructions
The lightning flash with arrowhead symbol, within an equila-
teral triangle, is intended to alert the user to the presence of
uninsulated "dangerous voltage", within the product's enclo-
sure that may be of sufficient magnitude to constitute a risk of
electric shock to persons.
A
The exclamation point within an equilateral triangle is inten-
ded to alert the user to the presence of important operating
and maintenance (servicing) instructions in the literature ac-
companying the appliance.
This product was designed and manufactured to meet
strict quality and safety standards. There are, however,
some installation and operation precautions which you
should be particularly aware of.
- should be read. before the appliance is operated.

be followed.
Water and Moisture - The appliance should not be used near
water-for example, near a bathtub, washbowl, kitchen sink,
laundry tub, in a wet basement, or neara Swimming pool, and
the like.
Wall or Ceiling Mounting - The cians should be mounted
to wall or ceiling only as recommended by the manufacture.
Ventilation - The appliance should be situated so that its loca-
tion or position does not interfere with its proper ventilation.
For example, the appliance should not be situated on a bed,
sofa, rug, or similar surface that may block the ventilation
openings; or, placed in a built - in installation, such as a
bookcase or cabinet that may impede the flow of air through
the ventilation openings.
@
Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.

power supply only of the type given above or as marked on
the appliance.
@
Power-Cord Protection - Power-supply cords should be rou-
ted so that they are not likely to be walked on or pinched by
items placed upon
or against them, paying _ particular
attention to cords at plugs, convenience receptacles, and the
point where they exit from the appliance.
@
Cleaning - The appliance should be cleaned only as recom-
men ded by the manufacturer.
Power Lines - An outdoor antenna should be located
xi
away from power lines.
Outdoor Antenna Grounding - If an outside antenna is
x2
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built up static charges. Section 810 of the National
Electrical Code, ANSI
/ NFPA No. 70-1984, provides informa-
tion with respect to proper grounding of the mast and suppor-
ting structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding
conductors,
location of
antenna. discharge unit, connection to grounding electrodes,
and
requirements for the grounding electrode.

Nonuse Periods - The power cord of the appliance shold be
|
un plugged from the outlet when left unused fora long period
of time.
@
Objectand Liquid Entry - Care should be taken so that objects
do not fall and liquids a are not spilled into the enclosure through
'openings.
