The rear connector that connects the main unit and the D.C.P is an extremely important part. Be careful not to
damage it by pressing on it with fingernails, pens, screwdrivers, etc.
Note:
If the D.C.P is dirty, wipe off the dirt with soft,
dry cloth only. And use a cotton swab soaked
in isopropyl alcohol to clean the socket on the

OVERVIEW OF THE RDS FUNCTION
Radio Data System (RDS) is a broadcasting service that allows FM stations to send additional
digital information along with the regular radio program signal. Your car stereo offers you a
variety of services. Here are just a few:
- PI (Program identification)
It is a code that identified RDS stations; it is unique for each station.
- PS (PROGRAM Service Name)
The name of current station, it is shown on the display.
Some broadcasting stations may change their program from normal broadcasting to regional
broadcasting for a certain period. When regional mode is off, the region identification in the PI code
is ignored; the radio may switch to a local variant of the current program. When region mode is on,
the radio will only switch to a program carrying the exact same PI code.
Note: When AF switch is on, at this moment use tuning up/down to search station will only
stop at station which has RDS broadcasting.
- TA (Traffic Announcement)
When an actual traffic bulletin is on air, the TA indicator will also turn on.
- AF (Alternative Frequencies List)
The list(s) of Alternative Frequencies give information on the various transmitters
broadcasting the same program in the same or adjacent reception area. If the main
frequency should get worse, the radio will tune automatically to the strongest Alternative
frequency.
- TP (Traffic Program)
If the tuned program carries Traffic Announcement, the TP indicator will turn on.
10

- PTY (Program Type Codes)
This code is used to designate the current program material being broadcast. With this feature, you
can search the programs that match the selected program type, which is chosen from a specific list of
types.
- EON (Enhanced Other Networks Information)
It is a supplementary service enabling the radio to obtain information not only from the current station
but also from the others.
- CT (Clock Time)
This function permits to update the clock of the receiver the nation from which the station is
broadcasting (from PI). It could happen that on the display will be shown the wrong hour; this happens
because in Italy the Clock Time function is not working yet.
Notes
Depending on the country or region, not all of the RDS functions are available in Italy.
RDS may not work properly if the signal strength is weak or if the station you are tuned to is not
transmitting RDS data.
PROGRAMMABLE OPTIONALS
- TA SEEK, TA ALARM
To determine what action will the radio take if the newly tuned station does not receive TP information
for 5 seconds.
TA SEEK
The radio retunes to a different station which contains TP information.
TA ALARM
The radio does not retune but beeps will be heard.
- PI SOUND, PI MUTE
When the vehicle is crossing the area where two stations with same AF but different PI code can be
received at the same time, the receiver will become unstable, under this situation two modes can
be selected.
PI SOUND
The different PI sounds will be heard.
PI MUTE
Under the same situation, the radio will be muted.
- RETUNE L, RETUNE S
To determine the initial time of automatic TA Search or PI Search.
RETUNE L 90 seconds
RETUNE S 30 seconds
To use this function press SEL Button for few seconds, each time you press this button the mode
will move and the functions will shown on the display, turn the volume knob to set the desires
functions ,the function states as following:
- BEEPS 2ND, BEEP ALL, BEEP OFF
To determine how the beep sound is generated when the keys are pressed.
BEEP 2ND Beeps only when the second function of the dual function button is selected (press for
few seconds)
BEEP ALL Beeps when any buttons is pressed.
BEEP OFF To disable the beep option.
- MASK PI, MASK ALL
“PI” is referred to “Different PI with same AF”.
During AF search, PI stations and non-RDS stations with strong signal will be masked, in the latter
case, the non-RDS stations may cause interference, resulting the real AF to be masked due to the
misjudgment of the radio under interference.
There are two options to handle this situation.
MASK PI to mask only the AF with different PI.
MASK ALL mask both PI and strong signal non-RDS stations.
