It does not need to be adjusted at the time of this
machine performing part exchange etc.,
since automatic adjustment is performed for every disk.
本機はﾃﾞｨｽｸ毎に自動調整が行われる為に、部品交換などを
行った際の調整は必要ありません。
ｵﾌﾟﾄﾋﾟｯｸｱｯﾌﾟのﾚｰｻﾞﾀﾞｲｵｰﾄﾞは、衣服や人体に帯電した静電
荷等で電位差を生じ、静電破壊を生じる危険があります。
修理時においては充分に注意し行って下さい。
The laser light of this machine is condensed so that
a focus may be connected in the shape of a reflective
side with the object lens in an Optical pickup.
Therefore,when you check luminescence of a laser diode,
please look aside more than 30㎝ from an object lens.
本機のﾚｰｻﾞ光は、ｵﾌﾟﾄﾋﾟｯｸｱｯﾌﾟ内の対物ﾚﾝｽﾞによってﾃﾞｨｽｸ
の反射面状に焦点を結ぶように集光されます。従って、ﾚｰｻﾞ
ﾀﾞｲｵｰﾄﾞの発光を確認する時は、対物ﾚﾝｽﾞより30㎝以上目を
離して下さい。
Handling needs to keep in mind that a flexible printed
circuit board tends to go out.
* When there is the necessity for solder, perform solder
iron point temperature before and after 270 degrees C.
* Please do not apply the solder iron point to
* same pattern to be careful repeatedly for power not to
join a pattern.
ﾌﾚｷｼﾌﾞﾙﾌﾟﾘﾝﾄ基板は切れ易いので取扱いは注意が必要です。
･ﾊﾝﾀﾞの必要がある時はｺﾃ先温度は270℃前後で行います。
･ﾊﾟﾀｰﾝに力が加わらないように注意が必要です｡
･同一ﾊﾟﾀｰﾝに何度もｺﾃ先を当てないで下さい。
The laser diode of an Optical pickup has a risk of pro-
ducing potential difference in electrical charged on
clothes or the human body, and producing Static
electricitydestruction.
At the time of repair, be carefully and carry out.

SUBJECT :(1) To prevent the output becomes nothing in unusual
(2) To be improve the reliability of lock in at external in
項目 :電源オン時、出力無しとなる可能性を防止する
:外部入力時、ロック外れになるのを防止する 。
Details ;(1).At the time of a power supply on,the IC8 of DSP Ass'y carries out incorrect
operation,and output relay does not turn on.
Countermeasure is follows,remove the R5 (22Ω) and add the jumper to both end
of R5 that located on DSP Ass'y (724-0055-00).
(2) An input is put into a coaxial input or an optical input, An output may be
interrupted when it is made to operate.
Countermeasure as follows, change the resistor value of R105 & R108 from 150Ω
to 330Ωthat located on DSP Ass'y(724-0055-00).
詳細; POWER ON時 DSP Ass'y内IC8 CS8427が誤動作し 出力ﾘﾚｲがONしない。
対策は DSP Ass'y(724-0055-00) R5(22Ω)削除しｼﾞｬﾝﾊﾟｰする。
; COAXおよびOPTに入力をいれ、出力すると音がとぎれる場合があります。
