ep-70/90 Feb. 2000 KEYBOARD SK-8P76-B (ep-70) ／鍵盤SK-8P76-B (ep-70) 2) Then, locate the bosses of the RUBBER SWITCHes in the round holes of the SPACERs, and as done for the SPACERs, put one RUBBER SWITCH 8PL, four RUBBER SWITCH 12P, one RUB- BER SWITCH 13P, one RUBBER SWITCH 7PH in order, start- ing on the lower tone side. At this time, carefully match the positions of the RUBBER SWITCHes, SPACER notches and air grooves. ( See Fig.3 and Fig.4 ) DISASSEMBLY ２）次に、SPACER の丸穴部にRUBBER SWITCH のボスを位置決め して、SPACER と同様に低音側より順にRUBBER SWITCH 13P, RUBBER SWITCH 7PH と置いていきます。 この際、RUBBER SWITCH とＳSPACER の外形切 （fig.3 fig.4 参照のこと） 分解手順 1.INSTALLATION OF PCB'S 1. 基板の取り付け方 Reauired Parts ／必要部品 Cutout Part fig.
3 Air-Escape Groove RUBBER SWITCH 1) First,turn the chassis over, noting that the right-and-left-hand sides are not revered. １）まず、シャーシを左右が逆にならないように裏返します。 次に、fig.1 に示すように左側（鍵の低音側）より、先ずSPACER 8PL を1 個、そしてSPACER 12P を４個、シャーシの位置決め穴 に合わせて順に置いていきます。（fig.2 参照のこと） 右側（高音側）にはSPACER 13P、SPACER 7PHを同様に置きます。 Then, as shown in Fig.1, put one SPACER 8PL and four SPAC- ERs 12P in this odrer, starting on the left-hand side ( lower tone side of the keyboard ) according to the chassis posi- tioning holes. ( See Fig.2. ) Positioning Boss (6 points) PCB SPACER Similarly, put the SPACER 13P and SPACER 7PH on the right- hand side ( higher tone side ) . fig.

As shown in Fig.6, there are three PCBs, LOW, MID and HI.
