SETTINGS OPERATION - RDS MENU
PI SOUND
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
Under above same situation, a mute sound will be heard for a short time.
3) RETUNE
RETUNE SHORT is the default setting. User now has 5 seconds to select RETUNE SHORT
or RETUNE LONG by pressing the /- buttons.
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.
4) MASK
MASK DIP is the default setting. User now has 5 seconds to select MASK DIP to MASK ALL
by pressing the /- buttons.
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 Europe.
