SWITCHES AND CONTROLS
CD FM MULTIPLEX STEREO
INDICATOR
When the tuner receives signals from an FM
Station broadcasting multiplex, this indicator lights
up to show that it is receiving a stereo broad-
cast. The indicator never lights when the tuner
is receiving a monaural FM broadcast.
CI TUNING INDICATOR
This closes when you have tuned to a station,
whether FM or AM. Set the tuning dial at the
point where the indicator closes as much as pos-
sible.
CI DIAL SCALE
The upper figures are for FM and the lower for
AM. For tuning, turn the "TUNING" knob.
~ SELECTOR
Use this switch to set the tuner to the broadcast
of your choice.
AM: for reception of medium-wave broadcasts.
FM: for rèception of FM broadcasts.
MPX: for reception of FM multiplex stereo
broadcasts.
CI NOISE FILTER
Turn this switch on to eliminate the noise when
using your tuner in a ferroconcrete building, a
block occupied by such buildings Or an area of
weak field intensity where you are likely to suffer
from noise.
CI MUTING
Turn this switch on to eliminate the noise you
hear when not tuned to any station. Keep it on
while tuning.
However, if the muting switch is kept on when
you receive weak signals, the sound may be
distorted or reception may become impossible.
In such a case, switch off the muting circuit.
(j FM-AFC
This prevents signals from an FM station from
drifting. This is likely to happen because of the
very high frequencies used. If it occurs, the
tonal quality deteriorates or you cannot hear the
program at alL. To avoid this, switch on the
FM-AFC after tuning in the station of your
choice. If you switch on the FM-AFC before
tuning, you may not be able to tune in accurately.
If the FM-AFC is kept on even when there are
a number of stations nearby, you may suffer from
their interference. In such a case, switch off the
FM-AFC.
