SAFETY PRECAUTION FOR 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. Laser Diode Properties Material: GaAIAs Wavelength: 780 nm Emission Duration: continuous Laser Output: max. 0.6 mW

· Namely, two speakers are connected in parallel to one amplifier. · In the Pro Logic BYPASS mode the amplifier for C-ch (center channel) and the amplifier for S-ch (surround channel) are in MUTE state. The SP output is cut. · In the normal mode of Pro Logic ON mode the amplifiers for C-ch and S-ch are in operative state, so that the SP output appears. · In the Phantom mode of Pro Logic ON mode the amplifier for C-ch is in MUTE state, so that the SP output is cut. The amplifier for S-ch (surround) is in operative state, so that the SP output appears

Output of only L-ch Output of only C-ch Output of only S-ch Output of only R-ch The test tone (noise) is repeatedly output for output period (2 sec). In this case the following indication appears repeatedly. TEST L-ch C-ch S-ch R-ch · Pro Logic ON Phantom mode Press the remote control TEST TONE button. Output of only L-ch Output of only R-ch Output of only S-ch The test tone (noise) is repeatedly output for output period (2 sec). In this case the following indication appears repeatedly. TEST L-ch R-ch S-ch Relation between VIDEO IN input and output in Pro Logic ON state (1) L-ch/R-ch same phase input into VIDEO IN input jack in VIDEO Function mode

· Accordingly, if you want to output signal waveform to C-ch SP out, give the same phase input into L-ch/R-ch INPUT in the Pro Logic Normal mode. If one of channels receives input, C-ch does not output. Only L-ch or R-ch outputs. · If you want to output signal waveform to S-ch SP out, you can use either Normal mode or Phantom mode. However, 180° reverse phase input must be given to L-ch/R-ch INPUT.

· 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. Exa: P1 has f1, f2, f3 (same PTY). Same PI code -- freq: different P2 has f4, f5 (same PTY). (AF'S) PS: same PTY: same [For example] Pickup and memorized to preset CH. --f1 f2 ---

Select signals (f1, f5, f7, f10) are memorized in the preset memory by ASPM. · If tentative - ASPM operation is repeated intententionally, 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-C470H CD-C470H/CD-C480H 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-C470H/CD-C480H) 1. PTY item: added TA.TTL 18 kind. 2. Each "TP", "TA" 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 stanb-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 add EON feature. 7. Added EON--TI, EON--PTY function. 3. Summary of CD-C470H/CD-C480H 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 automati cally stay and listen to TA of ON station switch back to TN station autmatically 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 toON station comparing field strength at the same time. But when the frequency of ON station exists in the preset-memory, then reciver switches straight to that ON station(CH), without comparing field strength so can make a quick switching from TN--ON sta tion. 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-C470H/CD-C480H's EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.

EON summary notice for reference 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 ONTN station continue to keep EON stand-by. 3. EON-TI Don't switch TNON during TN broadcast TA. (same item) 4. EON-TI/PTY EON can be cancelled during receiving ON station by pressing EON button if necessary and switch back ONTN. 5. EON-TI/PTY EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or powerOFF or Tun Up/ Down or change band or recall pre-set CH. 6. EON-TI/PTY After setting EON stand-by, stand-by items can be confirmed by pressing EON button one time. 7. EON-TI/PTY EON button function: ·EON setting ·Confirm stand-by items ·Cancel (ONTN) ·EON clear cancel (2 times) 8. EON-TI/PTY After setting EON-TI and EON-PTY stand-by, if when EON data is not transmitted, EON ind goes out and EON stand-by is automatically cancelled display "NO EON". 9. EON-TI EON-TI stand-by can't be set. When TP=0,TA=0(TN) even if EON ind. lights up and the EON button is pressed then "NO TI" is indication the display. 10. EON-PTY Don't switch TNON during TN broadcast same specified PTY. (same item of PTY) 11. EON-TI/PTY Switch TNON TN station one cycle. Never switch TNON1ON2 Other net to other net station. 12. EON-TI/PTY After switch TNON station. When ON station is NO RDS, NO signal, TA=OFF or different PTY items. The receiver switch back ONTN displaying "NO READY". 13. During receive ON station. when ON station become to be NO RDS, NO signal, TA=ON to OFF or different PTY item, The receiver switch back ONTN. 14. EON-TI/PTY Switch TNON in case of 2 more stations exist, comparing field strength and switch to the strongest station, if these signals are same strength, switch to the first previous station. If same frequency as AF'Sexists in the preset memory, then switch TNON (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. 15. Even if switch TNON preset memory straight, that ON station is very weak signal, then search another AF'S (ON) station comparing field strength and switch to the strongest station as a result. Of all atations of AF'S are very weak or no good condition, then, switch back ONTN automatically display "NO READY". 16. EON-TI/PTY No linkage volume, power ON/OFF, and switch function. 1. EON-TI/PTY
