SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements. However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
(1) When the cabinet has been removed, the power is turned
on without a compact disc, and the Pickup is on a position outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and
replacement service parts have already been adjusted prior to shipping.
(3) No adjustment to the Laser Power should be attempted
when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens
at any time.
(5) CAUTION - Use of controls or adjustments, or performance
of procedures other than those specified herein may result in hazardous radiation exposure.

Adjustment
Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely. Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.
Items adjusted automatically
(1) Offset adjustment (The offset voltage between the head
amplifier output and the VREF reference voltage is compensated inside the IC.)
* Focus offset adjustment * Tracking offset adjustment
(2) Tracking balance adjustment (waveform drawing 15-1
EFBL)
(3) Gain adjustment (The gain is compensated inside the IC
so that the loop gain at the gain crossover frequency will be 0dB.)

• ASPM SCAN: 87.50MHz 108.00 MHz.
• Only RDS signal is memorized by ASPM because RDS signal has PI code and is suitable and convenient for ASPM operation. ASPM Comparing field strength, only one strongest RDS station is memorized of all stations (repeater relay stations) that have same
PI code.
Each PI has AF’S list by individually.

• If tentative - ASPM operation is repeated intentionally, never memorized (over write) at the same frequecy. 1st time ASPM strongest stations of each PI are memorized.
ASPM is not only very usefull for PTY search, but also EON operation. 2nd time ASPM 2nd strong stations of each PI are memorized and so on. PTY search function is equal to FM band search function as a result.

1. Introduction of RDS for CD-BA160H/1700H.
CD-BA160H/1700H RDS function is equal to adding EON feature to the current CD-C75H RDS. EON feature is EON—PTY and EON—TI. Although PTY and TI indicators are separated, PTY contains TI in the PTY items (software) like current PTY search items.
NEWS, AFFAIRS, INFO, ALARM, TI (TTL 17 kinds)
EON—PTY EON—TI
Can select and stand-by Can select and stand-by
EON—PTY and EON—TI are basically stand-by receive the desired program of ON station.
2. The difference point from current CD-C75H RDS. (CD-C75H — CD-BA160H/1700H)
1. PTY item: added TA. (TTL 18 kind.)
2. Each “TP”, “T A” ind. light up or go out individually. “TA” ind. doesn’t light up on current model, CD-C75H due to none EON—TI.
3. Added 3 indicators(in FL) due to adding EON feature. EON: Lights up only during receiving EON data (14A). TI: During EON-TI stand-by Light up
During receiving ON station. blink.
PTY: During EON-PTY stand-by Light up
During receiving ON station. blink.
4. No adjust type (None adjusting circuit.)
5. Added EON button.
6. Need to change RDS logo due to the addition of EON feature.
7. Added EON—TI, EON—PTY function.
3. Summary of CD-BA160H/1700H RDS—EON operation
EON—PTY: Select and set the desired “PTY” stand-by switch to ON (other network) Station at the start of desired PTY
automatically → stay and listen to PTY of ON station switch back to TN (This net) station automatically at the end of PTY (ON) i.e. after changing to another PTY (except AFFAIRS) or cancelling to receive PTY of ON station midway.
EON—TI: Select and set the “TI” stand-by switch to ON station at the start of traffic announcement automatically stay
and listen to TA of ON station switch back to TN station automatically at the end of TA (ON). ie after TA (ON) is over or cancelled to receive TA of ON station midway.
When switching TN ON station. In case of exist 2 more stations having the desired (specified) “PTY” or “TI”, the receiver will select and switch to ON station comparing field strength at the same time. But when the frequency of ON station exists in the preset-memory, then receiver switches straight to that ON station (CH), without comparing field strength so can make a quick switching from TN—ON station. Preset memory takes priority of switching TN—ON station. Therefore ASPM is usefull not only for PTY search but also for rapid EON switching. Anyway CD-BA160H/1700H EON is basically stand-by and receiving method, along with the Guidelines for EON implementa­tion.

EON summary notice for reference
1. EON-TI/PTY EON stand-by can be set, only when EON ind. lights up. While EON ind. goes out (NO EON STATION), EON stand-by can't be set. If the EON button is pressed, then “NO EON” is indication the display.
2. EON-TI/PTY Even if switch back ON TN station continue to keep EON stand-by.
3. EON-TI Don’t switch TN ON during TN broadcast TA. (same item)

5. EON-TI/PTY EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or power OFF

11. EON-TI/PTY Switch TNON TN station one cycle.
12. EON-TI/PTY After switch TN ON station. When ON station is NO RDS, NO signal, TA=OFF or different PTY items.
13. During receive ON station. when ON station become to be NO RDS, NO signal, TA=ON to OFF or different
14. EON-TI/PTY Switch TN → ON in case of 2 more stations exist, comparing field strength and switch to the strongest station,
15. Even if switch TN ON preset memory straight, that ON station is very weak signal, then search another
16. EON-TI/PTY No linkage volume, power ON/OFF, and switch function.
EON can be cancelled during receiving ON station by pressing EON button if necessary and switch back ON→TN. or Tun Up/Down or change band or recall pre-set CH.
• Confirm stand-by items
• Cancel (ONTN)
• EON clear cancel (2 times) EON stand-by is automatically cancelled display “NO EON”. pressed then “NO TI” is indication the display.
Never switch TN ON1 ON2 Other net to other net station. The receiver switch back ON TN displaying “NO READY”. PTY item, The receiver switch back ON TN. if these signals are same strength, switch to the first previous station.
If same frequency as AF'Sexists in the preset memory, then switch TN ON (preset memory station) straight. In case of exist 2 more preset memories of AF’S,then switch to the preset CH which taken in EON DATA first, also in this case no concern to field strength.

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 pro-
gramme signals. For e xample, the stations send their stat ion
names, and information about what type of programme they
broadcast, such as sports or music, etc.
When tuned to an FM station which provides the RDS ser-
vice, the RDS will appear, and the station frequency (and
then the station name if sent) will be displayed.
"TP" (Traffic Programme) will appear on the display when
the received broadcast carries traffic announcements, and
"TA" (Traffic Announcement) will appear whilst a traffic
announcement is received.
"EON" will appear whilst the EON (Enhanced Other Net-
works information) data is broadcast.
"PTYI" (Dynamic PTY Indicator) will appear whilst the
Dynamic PTY station is received.
Note:
"TP" and "T A" appear at the same time during an announce-
ment. When only "TA" appears, an announcement is not
made.
Information Provided by RDS
With the CD-BA1700H, you can display three 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 infor-
mation.
Descriptions of the PTY (Programme Type) codes, TP (Traf-
fic Programme) and TA (Traffic Announcement) With the

PTY, TP and TA signals.

NOTES ON SCHEMATIC DIAGRAM
Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.
Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type
