RDS (Radio Data System) OPERATION
RDS is a broadcasting service which a growing
number of FM stations are now providing. It al-
lows these FM stations to send additional signals
along with their regular programme signals. For
example, the stations send their station names,
and information about what type of programme
they broadcast, such as sports or music, etc.
When tuned to an FM station providing the RDS
service, RDS will appear, the station frequency
(and then the station name if sent) will be dis-
played.
The TP (Traffic Programme) will appear on the
display when the received broadcast carries traf-
fic announcements, and the TA (Traffic An-
n o u n c e m e n t)  w i ll  a p p ea r  wh il s t  a  tr af fi c
announcement is being received.
EON will appear whilst the EON (Enhanced Other
Networks information) data is being broadcast.
Note:
When the TP and TA appear at the same time,
an announcement is being made.
When only the TA appears, an announcement is
not being made. (See page 21.)
Information Provided by RDS
With the XL-570H/XL-560H, you can display two
types of RDS service. To show them in the dis-
play, press the DISPLAY MODE button.
Each time you press the DISPLAY MODE button,
the display will change to show the following in-

TEST MODE
The test mode applied to this microcomputer has three modes, namely ordinary test mode to be used for adjustment or
measurement, aging test mode to be used for aging test, and self-diagnosis test mode for self-inspection in case of final product
inspection.
The test mode specification prescribes the microcomputer with RDS (RH-IX0014SJZZ  Serial No. 904xxxxx) and the microcomputer
with RDS (RH-IX0021SJZZ  Serial No. 905xxxxx~ ).
1.  Turning on the test mode
To turn on the specific test mode, press the POWER button, holding down the following two buttons in the ordinary stand-by
mode (power off state). In this case only the main unit button is valid. Even when the POWER of remote control button is set
to on, the test mode is not turned on.
[Ordinary test mode]
1. CD  Test Mode (TEST 1)………………………… BASS/TREBLE + PLAY
2. Tuner Test Mode (TEST 2)……………………… FF/FWD + MEMORY/SET
3. Electronic volume Test Mode (TEST 3)………… STOP + BASS/TREBLE
4. Timer Test Mode (TEST 4)……………………… FF/FWD + BAND
5. LCD Test Mode (TEST 5)………………………… MEMORY/SET + REW/REV
FF/FWD + REC PAUSE
[Self-diagnosis Test Mode]
1.  Button input diagnosis test mode (TEST6).………
* Only for this mode four turning-on buttons are ……
   provided. The differ insignificantly in processing
   after turning-on.
   For the microcomputer without RDS, there are two
turning-on buttons, since the two buttons (using the
RDS buttons) are not provided.
