• Aconsejamos llevar a cabo las medidas con el METRATESTER 4
(Instrumento de medida para la comprobación de aparatos eléctri-
cos según VDE 0701).

• Si no se cumple la seguridad del aparato, porque
- 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
• Emplear sólo componentes originales.
Con componentes o grupos constructivos con el indicativo de se-
guridad
!
son de obligada necesidad piezas de repuesto origina-
les.
• Las partes del aparato que contribuyan a la seguridad del mismo no
deben estar deterioradas ni ser manifiestamente inadecuadas.
• Esto es especialmente válido para aislamientos o piezas aislantes.
• Los cables de red y de conexión se comprobarán, antes de conec-
tarlos, en cuanto a defectos externos. Comprobar el aislamiento.
• Se ha de comprobar la función de seguridad de la compensación de
tiro o de los manguitos de protección contra doblamientos.
• Repasar los puntos de soldadura sometidos a carga térmica.
• Mantener libres los canales aireación.

Disposiciones para la seguridad
Después de operaciones de servicio en aparatos de la clase de
proteccion II, se llevará 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
instalación.
Este aparato corresponde a la clase de protección II, reconocible por
el sìmbolo
.
• Medida de la resistencia de aislamiento según VDE 0701.
Aplicar el medidor de aislamiento (U
prueba
= 500V-), simultáneamen-
te, a los dos polos de red y entre todas las partes del mueble o de
funciones ( antena, conectores, teclas, tornillos, etc.) de metal o
aleaciones metálicas. El aparato estará libre de defectos con:

Observación: En aparatos de la clase de protecciòn II, condicionado
por la construcción y por resistencias de descarga, el valor de medida
de la resistencia de aislamiento puede ser inferior a < 2M
Ω
.
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

Safety Instructions
The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated "dangerous voltage", within the
U.S. & Canada
USA
product´s enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to persons.
The exclamation point within an equilateral triangles is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
This product was designed and manufactured to meet strict
quality and safety standards. There are, however, some installa-
tion and operation precautions which you should be particularly
aware of.
•
Read Instructions - All the safety and operating instructions
should be read before the appliance is operated.
•
Retain Instructions - The safety and operating instructions should
be retained for future reference.
•
Heed Warnings - All warnings on the appliance and in the opera-
ting instructions should be adhered to.
•
Follow Instructions - All operating and use instructions should be
followed.
•
Water and Moisture - The appliance should not be used near
water-for example, near a bathtub, washbowl, kitchen sink, laun-
dry tub, in a wet basement, or near a swimming pool, and the like.
•
Wall or Ceiling Mounting - The appliance should be mounted to
wall or ceiling only as recommended by the manufacturer.
•
Ventilation - The appliance should be situated so that its location
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 Sources - The appliance should be connected to a power
supply only of the type given above or as marked on the appliance.
•
Power-Cord Protection - Power-supply cords should be routed 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 recommen-
ded by the manufacturer.
(x1)
Power Lines - An outdoor antenna should be located away from
power lines.
(
x2
) Outdoor Antenna Grounding - If an outside antenna is 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 information with respect to proper groun-
ding of the mast and supporting structure, grounding of the lead-
in wire to an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.
•
Nonuse Periods - The power cord of the appliance should be
unplugged from the outlet when left unused for a long period of
time.
•
Object and Liquid Entry - Care should be taken so that objects do
not fall and liquids are not spilled into the enclosure through
openings.
•
Damage Requiring Service - The appliance should be serviced by
qualified service personnel when: The power-supply cord or the
plug has been damaged; or objects have fallen,or liquid has been
spilled into the appliance; or the appliance has been exposed to
rain; or the appliance does not appear to operate normally or
exhibits a marked change in performance; or the appliance has
been dropped, or the enclosure damaged; or the batteries have
been damaged.
•
Servicing - the user should not attempt to service the appliance
beyond that described in the operating instructions. All other
servicing should be referred to qualified service personnel .
Items (x1) and (x2 ) apply only to receivers or tuners.
