When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the soldering points with the Pb free solder until it melts enough. 7 SA-PM41P

11、 / SA-PM41PC This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. When the unit is turned on: 5 Precaution of Laser Diode CAUTION: 1. Do not look directly into the pick up lens. 2. Do not use optical instruments to look at the pick up lens. 3. Do not

12、 adjust the preset variable resistor on the pickup lens. 4. Do not disassemble the optical pick up unit. 5. If the optical pick up is replaced, use the manufacturers specified replacement pick up only. 6. Use of control or adjustments or performance of procedures other than those specified herein ma

13、y result in hazardous radiation exposure. CAUTION! THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. 8 SA-PM41P / SA-PM41PC 6 Handling Precautions For Traverse Deck The laser diode

14、in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). Handling of traverse deck (optical pickup) 1. Do not subject the trav

15、erse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock. 2. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FFC board). 3. Take care not to apply excessive stress to the flexible board (FFC board).

16、 When removing or connecting the short pin, finish the job in as short time as possible. (Fig 6.1) 4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted. Grounding for electrostatic breakdown prevention 1. Work table grounding. (Fig 6.2) Use the anti-static wris

17、t strap to discharge the static electricity from your body. 2. Work table grounding. (Fig 6.2) Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, and ground the sheet. Caution: The static electricity of your clothes will not be grounded th

18、rough the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup). Caution when replacing the Traverse Deck The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the s

19、hort point before making connections. (Fig 6.1) (Figs 6.2) 9 SA-PM41P / SA-PM41PC 7 Accessories Note : Refer to Packing Materials It displays it. When the operation which enters the doctor mode in the doctor mode is done, version No. of EEPROM; It is (DEC display) and a check sum (HEX display). 1. D

Press 4 button on the remote control. Data shall be set in order to make a cold start (backup data are initialize

22、d) when reset starts next time. To clarify that the code was accepted at this time, the pattern below is displayed in the LCD for 2 seconds. (Note) In the case that you unplug from AC outlet after this mode was set, then plug to AC again, a cold start shall begin. And “- - - - - - - - -” is displaye

Errors are stored in the unit memory. To clear memory, press and hold down STOPn/-DEMO” button for 5 seconds or more during self-diagnos

24、tic mode. The message, “CLEAR” appears on the display when memory is erased, and the unit displays the message, “T”. Memory is not affected by turning off the power or unplugging the socket. Be sure to clear memory after repair is completed. 3. Press STOPn/-DEMO” button. A symbol of self-diagnostic

25、is indicated on the display if an error is found. If several errors are found, a respective indication is displayed when STOPn/-DEMO button is pressing repeatedly. (e.g. H01 CD F15 F01) If no error is found, only T indication is displayed and remains unchange even if STOPn/-DEMO button is pressed. 1

26、2.3. Displaying Self-Diagnostic Results (H01, H02, H03, F01, F02) 1. Enter the self-diagnostic mode, following the instructions described in 12.1.1 Setting of the Self-Diagnostic Mode. 2. Insert a normal-positioned music tape with erase prevention niches on both Sides A and B. Press TAPE button to a

27、ctivate the TPS operation so that the tape automatically stops at an interval between music selections. 3. Press STOPn /-DEMO and TAPE buttons together on the remote controller. (Recording does not start.) 4. Then, insert a Cr02-positioned blank cassette tape with an erase prevention niche of Side A

28、 or B set to the left side. 5. Press /FF/ button. The tape will be forwarded and automatically stop after two seconds. 6. Remove the cassette tape, and set the other side. 7. Press /REW/ button. The tape will be rewound and automatically stops after two seconds. 8. Press STOPn/-DEMO button on the un

29、it. If an error is found, a self-diagnostic key appears on the display. If several errors are found, the display shows these keys when STOPn/-DEMO button is pressed repeatedly. (Ex.: H01 - H02 - F01 - H01) If no error is found, only the message, “T” appears on the display. (*1) TPS operation (music

30、search) detects the blank sections between music selections. Therefore, do not use tapes with the following conditions: A blank section that lasts only 4 seconds or less. No blank sections (recording through microphones, etc.). Music selections that have extremely low pitches or prolonged silent sec
