VIDEOPORTERO DIGITAL 5 HILOS
The ADS KIT amplifier incorporates
electronic protection circuits against
installation wiring faults presenting,
in each case, the symptoms
explained in the
TROUBLESHOOTING TABLE. If
when making a call the Diagnostic
LED emits short blinks, this
indicates that there is a short circuit
between «+» and «L», or inverted ca-
bles.
The on-off indicator shows if the Monitor
is on.
The ON/OFF switch
must be ON.
For prolonged periods of absence, turn
off the Monitor with this switch and it is
completely disconnected.
