RDS (Radio Data System) OPERATION

RDS is a broadcasting service which a growing
number of FM stations are now providing. It al­lows 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 dis­played.
The TP (Traffic Programme) will appear on the
display when the received broadcast carries traf­fic announcements, and the TA (Traffic An­nouncement) will appear whilst a traffic
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 dis­play, press the DISPLAY MODE button.

XL-560H/E,570H/E

3. Tuner Test Mode (TEST 2)

1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH without

frequency setting by adjusting personnel when the tuner section is adjusted in the production line.

2. Details of tuner test mode
When the power is turned on by using the "POWER" button while the "FF/FWD" and "MEMORY/SET" buttons are held down

in POWER OFF state, the frequency for adjustment and measurement of destination specified by the AREA terminal is preset
and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation (destination selected
by SPAN switching operation) set when the test mode is set. (As for frequencies to be preset and stored for each destination,

refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary operations of TUNER function. However, FUNCTION switching

is invalid.
Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are

written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected

in case of initial setting so as to ensure memory initialization.

When the tuner test mode is turned on, the following indication lights for one second.

• The TUNER TEST2 mode is set as a result of >> + MEMORY + POWER. -> IF AC is set to OFF in the TEST2 mode, the initial
state is restored.

When POWER is set to OFF, the memory of TEST2 mode is protected.
When the power is turned on again, the ordinary operation is enabled while the data is stored in the
memory (besides TUNER).

If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.

• To clear the whole memory, insert the AC cord, holding down MEMORY + BASS/TREBLE.

station 105.50 MHz) and VSM is greater than 105.50 MHz (PR-01), data is overwritten on 105.5 MHz which is contained in
"PR-01". (Frequency is changed to 107.50 MHz.)
If VSM is equal, previously stored 105.50 MHz remains.

When RDS station is stored in the test mode, the 2-second blinking of preset No. is not performed so as to save the production

resumed, the PS name indication is restored.

When the PS data is given in case of NO PS indication, the
PS name indication is restored.

Note: If PS is fixed after the frequency indication is

resumed, the PS name indication is restored.

Note: RDS operation is performed in FM MONO state. However, in case of ASPM, ASPM scan is performed after BAND is

changed from FM MONO to FM STEREO.

Note: When the (PLAY) button is pressed in TEST 2 mode, it is possible to check the sate of IF count. However, this

function is for designer. It is not necessary for other sections.

B) Cautions concerning the ASPM test mode
a) Cancel: When the "ASPM" button is pressed again during operation after it was first pressed in the test mode, the ASPM

test mode is canceled (interrupted), and the initial state FM 106.50 MHz (ST) indication is restored.

(To check the data which was preset and stored until interruption, use the preset UP/DOWN button. (JOG UP/DOWN is

also available after JOG mode button operation.)

wing indication appears.
b) The ASPM test mode is started in FM stereo state (FM 106.50 MHz ST). If any button other than ASPM button is pressed

even only once after it is started, it becomes invalid, and the ASPM test mode becomes inoperable.

Invalid: The Ordinary mode is set while 4 to 30CH data remain in memory (or 1 to 30 CH MAX data remain in memory).
The "ASPM" button can be repeatedly operated until 01CH to 03CH is filled (up to 3 stations in memory).

The number of stored stations -> Channel No. -> Frequency -> FM 106.50 MHz (ST) is indicated.
(1 second) (1 second) (1 second) (Initial state)

Up to 3 stations (1 to 3CH) can be indicated. This indication is
given only in the ASPM test mode. In other mode (not in ASPM
test mode) the number of stored stations -> END is indicated

c) Broadcast (without PI code) which is not RDS is not preset and stored in memory.
When the ASPM mode is set, the "MEMORY/SET" button cannot be operated (the test mode is canceled).
Operation is possible after ASPM test mode operation.

d) Scan frequency: 105.00 MHz -> 108.00 MHz
Data are stored in memory so that the PI code is not duplicated (by seeing the PI code and VSM (S meter value). When

the PI code is duplicated, both VSM (S meter value) are compared. The greater one is stored in memory but the smaller
one is discarded.

For the stations having the same PI code, only one station having the highest electric field intensity is stored, and the

memory is refilled. The channels which can be preset in the ASPM test mode are 01 to 03CH. If 3 stations are stored, 30
CH are filled.

For the stations having the same electric field intensity, the former (preceding station) is stored.
e) Signal of already stored same frequency is not stored. (The previously stored data is kept.)
f) The order of preset memory is 01CH -> 02CH -> 03CH.
g) When 01 to 03CH were all used, scan is aborted at the frequency at which filling occurred, and the following indication

appears.

Number of stored stations -> Indication of stored channel -> Indication of frequency -> Return to initial FM 106.50 MHz (ST)
(1 second) (1 second) (1 second)

In this period up to 3 stations are continuously indicated (1 to 3 CH).

h) If even one station could not be preset and stored in the APMS mode, "_0MEMORY" is indicated after scanning, and then

FM 106.50 MHz (ST) indication is restored. (The first digit is space.)

("_0MEMORY" is indicated in the test mode.)
i) When the "ASPM" button is pressed after three stations are stored (after full-memory of 30 stations), "ASPM" blinks for 2

seconds, and then FM 106.50 MHz (ST) indication is restored without ASPM scanning. (RDS automatic lighting)

(In case of ASPM button operation in full memory state)
j) After completion of specific operation FM 106.50 MHz (ST) indication is restored.
k) Test mode

Use of only the function button is inhibited.
l) The first channel to be called (when data is stored in the ASPM mode) is 01CH.
m) After start-up in the ASPM test mode the ASPM key is valid even when it is pressed many times. The test mode is kept.

If three stations are stored (1 to 3CH), full-memory state occurs.
If the ASPM button is pressed after occurrence of full-memory state, the same operation as that described in item i) is

performed.

4. Electronic volume Test Mode (TEST 3)

When the test mode is set, the following indication lights for one second.

When this mode is set, BASS/TREBLE is set to 0 (0 dB) and SURROUND mode is set to off, and start-up function is set to CD
when volume is -14 dB (STEP 17). The button operations in the test mode are the same as those of ordinary operation excepting
sound volume UP/DOWN.

(1) The indication is the same as that of ordinary operation excepting test mode setting.
(2) The sound volume control with the sound volume UP/DOWN button is only the following 3 steps unlike the ordinary state.

Volume- ∞ (STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)

(3) BASS/TREBLE and SURROUND are switched when button operation is performed.

5. Timer test Mode (TEST 4)

When the test mode is set, the following indication lights for one second.

The current time and timer time are set in the following procedure to perform the timer playback.

1.Set the current time to 1:00, set the timer to ON time 1:02, set the function to Tape, and set volume STEP 8. One minute is counted
as one second, and the timer playback operation is performed. The fade-in (when playback is started) is executed at a rate of
one step for 0.5 sec. After completion of fade-in the fade-out is executed at a rate of one step for 0.5 sec (WAIT 1 sec inserted).
After completion of fade-out the power is turned off (after WAIT 1 sec), and the mode is changed to the standby mode.

The indication during operation is the same as that of ordinary timer operation.

6. LCD Test Mode (TEST 5)

When the LCD test mode is set, all the LCD segments are lighted. After that the indication is changed as follows according to
the "PLAY" button input.

Lighting of all segments Lighting of odd segments Lighting of even segments

7. Key input diagnosis Test Mode (TEST 6)

When the test mode is set, the following indication appears.

This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode checking
as to whether the "POWER" button was pressed after all the buttons shown below were pressed is performed. If the result is
OK, OK is indicated. Even any one of keys was not pressed, an error is indicated. In case of OK termination or error termination
exit from this mode occurs when the "POWER" button is pressed next time, and the standby mode is set.

All the models using this microcomputer do not use the same buttons. Some models do not have specific buttons. Accordingly,
the input of the following buttons is detected by using the combination of buttons to be pressed together when this mode is turned
on.

The button pressing order is not specified. Checking as to whether all the buttons were pressed is executed.

1. In case of "FF/FWD" + "REC PAUSE" (XL-560E/570E Only)
Since RDS and SURROUND are not provided, the following 11 buttons are detected as all buttons.
PLAY, JOG MODE, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP, CLOCK/TIMER/
SLEEP

2. In case of "FUNCTION" + "RDS PTY-TP" (XL-560H/570H Only)
Since SURROUND and RDS are provided, the following 16 buttons are detected as all buttons.
PLAY, JOG MODE, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP, CLOCK/TIMER/
SLEEP, PTY-TI, EON, APMS, DISPLAY, SURROUND

(RDS circuit is only for XL-560H/570H)
The OK/NG indication of test result is as follows.
