Problem:
The RDS station name does not appear
on the integral screen.
Cause 1:
The station does not broadcast RDS
information, or the station is not correctly
tuned.
Remedy:
Tune in the station so that the tuning
indicator is central.
Cause 2:
The station is received with interference, or
the field strength is too low.
Remedy:
Select stations which can be picked up
without background hiss and interference
or other problems.
Problem:
Whistling or warbling sounds from the
loudspeakers.
Cause:
The aerial lead is positioned too close to a
mains, M
LINK
or Cinch lead.
Remedy:
Deploy the cables with adequate spacing
from each other. Use a permanent domes-
tic aerial or cable connection.
Problem:
The machine operates normally, but
picks up very few stations, or even none
at all.
Cause:
The aerial system or aerial cable is defec-
tive.
Remedy:
Check the aerial cable for good contact in
the aerial socket and on the machine itself.
There must be no damage, and no kinks in
the cable. If necessary fit a new aerial
cable.
Problem:
After a house-move the integral screen
still displays the old program names -
but the stations can no longer be picked
up.
Cause:
Presets with station names and reception
frequencies are still stored in the machine,
but they can no longer be received in the
new locality.
Remedy:
Erase all the stored presets:
• Switch on the system and wait until the
symbol on the screen stops flashing.
• Now hold the
button pressed in
until a running script appears on the
screen.
• While the script is still running, hold the
button on the remote control
handset pressed in until the screen
displays the message '
PRES-CLR
PRES-CLR
PRES-CLR
PRES-CLR
'.
• All presets are now erased.
