MEASURING CONDITIONS
The direct voltages and waveforms should be
measured relative to the nearest earthing point on
the p.c. board.
The direct voltages should be measured as follows:
Do not apply an aerial signal. Adjust receiver for
minimum brightness, maximum saturation and
contrast.
The waveforms should be measured under the
following conditions:
a. Use a colour-bar pattern as input signal.
b. Connect an oscilloscope (0.1 V/div.-DC) to point 6
of 1C7260 via an 10:1 attenuator probe.
Set the saturation control to obtain 3 V d.c.
. Connect the oscilloscope to point 16 of 1C7260.
. Set the brightness contro! so that the level of the
black bar in the video signal is situated at 2.7 V.
. Set the contrast control for a video signal
amplitude of 2.4 V.

SYMBOL FOR SAFETY RESISTORS
rN
Ved udskiftning af komponenter med dette symbol
skal der anvendes samme type, samt samme
verdier
for
ohm
og
watt.
Den
nye
komponent
skal
monteres pa samme made som den udskiftede.
When replacing components with this symbol the
same type has to be used, also the same values for
ohm and watt. The new component is to be mounted
in the same way as the replaced one.

medferer
en
drastisk
forkortelse
af
levetiden.
Nar man udforer reparationer, skal man sorge for, at
man er forbundet til samme potentiale som appa-
ratet via et handledsband med indbygget modstand.
Komponenter og verktej skal ogs4 holdes ved dette
potentiale.
All ICs and many other semi-conductors are suscep-
tible to electrostatic discharges (ESD) Careless
handling during repair can reduce life drastically.
When repairing, make sure that you are connected
with the same potential as the mass of the set via a
wrist wrap with resistance.
Keep components and tools also at this potential.
