10、f Laser Diode Caution : This product utilizes a laser diode with the unit turned ON, invisible laser radiation is emitted from the pick up lens. Wavelength : 780 nm Maximum output radiation power from pick up : 100 W/VDE Laser radiation from pick up unit is safety level, but be sure the followings:

11、1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pick up lens for a long

15、ing Precautions For Traverse Deck The laser diode 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 travers

16、e deck (optical pickup) 1. Do not subject the traverse 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 e

17、xcessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish the job in as short time as possible. (Fig 7.1) 4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted. Grounding for electrostatic breakdown prevention 1. Work t

18、able grounding. (Fig 7.2) Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding. (Fig 7.2) 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 e

19、lectricity of your clothes will not be grounded through 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

20、breakdown. Be sure to remove the solder from the short point before making connections. (Fig 7.1) (Figs 7.2) 8 SA-PM41E / SA-PM41EB / SA-PM41EG 8 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 E

CHK-NO when display when judged that there is EEPROM, and judged it not is. It returns to the doctor mode display of

22、usually by the operation which enters the doctor mode of usually by the operation which enters the doctor mode again with the check sum displayed. (The display does not return by the time limitation) 13.1.4. Cold start setting 1. Doctor mode ON. 2. Press 4 button on the remote control. Data shall be

23、 set in order to make a cold start (backup data are initialized) 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,

24、 a cold start shall begin. And “- - - - - - - - -” is displayed in the FL for 2 seconds. 13.2. Clearing Self-Diagnostic Memory (CD Section) (F15, F17, F22, F26, F27, F28, F29) 52 SA-PM41E / SA-PM41EB / SA-PM41EG 1. Enter into self-diagnostic mode. 2. Errors are stored in the unit memory. To clear me

25、mory, press and hold down STOPn/-DEMO” button for 5 seconds or more during self-diagnostic 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 memor

26、y after repair is completed. 3. Press STOPn/-DEMO” button. A symbol of self-diagnostic 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

27、T indication is displayed and remains unchange even if STOPn/-DEMO button is pressed. 13.3. Displaying Self-Diagnostic Results (Cassette Deck Section) (H01, H02, H03, F01, F02) 1. Enter the self-diagnostic mode, following the instructions described in 13.1.1 Setting of the Self-Diagnostic Mode. 2. I

28、nsert a normal-positioned music tape with erase prevention niches on both Sides A and B. Press TAPE button to activate 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

29、does not start.) 4. Then, insert a Cr02-positioned blank cassette tape with an erase prevention niche of Side A 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/ bu

30、tton. The tape will be rewound and automatically stops after two seconds. 8. Press STOPn/-DEMO button on the unit. 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 -

31、H02 - F01 - H01) If no error is found, only the message, “T” appears on the display. (*1) TPS operation (music 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

32、(recording through microphones, etc.). Music selections that have extremely low pitches or prolonged silent sections (such as classical music). and/or Music recorded with fade in/out effect. 13.4.
