OPERATION
When newly tuned station has not
RDS
signal, “PI SEEK” is
suppressed somewhat.
b).I SOUND or PI MUTE
While AF switching is implemented in
C201 station, AF can switch to 100
MHz, which is non genuine AF (where,
different PI with same AF) in short
“DIP”.
If a car cruises that critical area back
and forth, an oscillation
phenomenon
can be occurred,
because the different PI code can be
received from 100 MHz with “XXX” PI.
The car radio has special procedure
to
reduce even this kind of
unavoidable situation however there
is a limit to be escaped from this
serious case perfectly.
In that serious case, 2 mode is
selectable as follows:
- PI SOUND mode:
When above different PI sound (DIP)
is heard once in a while, the DIP’s
sound will be heard for a short time.
- PI MUTE mode:
Under above same situation, a mute
sound will be heard for a short time.
c).ETUNE L or RETUNE S mode
The initial time of automatic TA search
or PI search modes is selected.
When PI information is not caught for
retune time, the radio starts to retune
to next same PI station.
When same PI station does not catch
1 cyclic search, the radio goes to last
station and waits for several minutes
until PI code is received.
-
- RETUNE L mode:
- Selected as 90 seconds.RETUNE
S mode:
Selected as 30 seconds.
d).ASK DPI or MASK ALL mode
The AF frequency (which has different
PI or NO RDS signal with high field
strength) is masked during checking
PI when the unit searches AF. The
unit doesn’t search this AF (DIP) for
few minutes. In the case of the AF of
NO RDS signal with high field
strength, if the real AF is wrongly
masked as DIP by some interference,
the unit hesitates to search real Afs.
For this reason, the unit has the user
option (MASK DPI) which doesn’t
mask the AF of NO RDS signal with
high field strength. In MASK DPI
mode, the wrong sound or long mute
(according to PI SOUND or PI MUTE)
can be heard from the AF station
which has NO RDS signal and of
which the field strength is higher than
that of the currently tuning AF (station).
But, these phenomenons are rare and
the user will hardly hear the wrong
sound in whole Europe.
- MASK DPI mode:
Masked only the AF which has
different PI.
- MASK ALL mode:
Masked the AF which has different
PI and NO RDS signal with high
field strength.
e).BEEP
ON/OFF mode
- BEEP ON
The beep is generated when every
key is pressed.
- BEEP OFF mode:
The beep is disabled.
