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 exam-
ple, the stations send their station names, and in-
formation 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,thestation frequency (and
then the station name if sent) will be displayed.
The TP (Traffic Programme) will appear on the dis-
playwhenthe received broadcast carries traffican-
nouncements, 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.
■Information Provided by RDS
Withthe XL-60H/XL-70H, you candisplay two types
of RDS service. To show them in the display, press
the DISPLAY MODE button.
Each time you press the DISPLAY MODE button,
the display will change to show the following in-
formation.

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 "Volume/JOG Dial Selector" and "Volume Select"
buttonsare helddown inPOWEROFF state,thefrequency foradjustment andmeasurementof destinationspecifiedby the
AREAterminalispreset and storedinthe preset memoryCH.However, Ordinary1andOrdinary 2areset to thedesignation
(destinationselectedbySPANswitchingoperation)setwhenthetestmodeisset.(Asforfrequenciestobepresetandstored
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
writteninthememorytobecheckedincaseofmemorycheck(incaseofinitialsetting)sothatmemoryabnormalityisdetected
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 Volume Select + 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 + PLAY.
When the following operation buttons are pressed in this sate, the operation is executed as follows.
"POWER".................The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD".................The pickup slides toward the outer periphery while this button is held down.
"REW/REV"..............The pickup slidestoward the innerperipherywhile thisbuttonis helddown.However, ifPU-INis on,input

"PLAY" .....................Invalid
"STOP".....................Return to step 1
*If the focus is disturbed, the process returns to step 1.
Other cautions
• TOC IL is not executed in the test mode.
• As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted.
5. Step 5 Mode
The CD initialization operation flow is executed to the end, the mute is set to off, and playback is started. Even when the
playback reaches the outermost periphery of disc, the operation does not stop. The LCD display indicates the playback past
time as in case of ordinary CD playback.

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)
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.
Up to 3 stations (1 to 3CH) can be indicated. This indication is
givenonlyintheASPMtestmode.Inothermode(notinASPM
test mode) the number of stored stations -> END is indicated
* When the "PRESET UP" button or "PRESET DOWN" button is pressed after completion, the following indication appears.
* If signal exists at 106.50 MHz, the following indication appears.
In case of memory storage with ASPM, for example, if RDS station 107.50 MHz has the PI code (the same as that of RDS
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.

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.

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
whenvolumeis-14dB(STEP17).Thebuttonoperationsinthetestmodearethesameasthoseofordinaryoperationexcepting
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.
The current time and timer time are set in the following procedure to perform the timer playback.
1.Setthecurrenttimeto1:00,setthetimertoONtime1:02,setthefunctiontoTape,andsetvolumeSTEP8.Oneminuteiscounted
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.
5. Timer test Mode (TEST 4)
When the test mode is set, the following indication lights for one second.
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)
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.
In this period up to 3 stations are continuously indicated (1 to 3 CH).
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
