The PH701, 702 are mounted on the MAIN board, therefore the idler gear (A) (side S and side T) cannot be detected with the MAIN board removed. As a result, the motor (M601) cannot be controlled, causing malfunction. Further, the DIRECTION switch (S702) is also mounted on the MAIN board, and with the board removed, the mechanism position cannot be detected and the operation is not changed over. Therefor, when the voltage check is executed with the MAIN board removed, follow the procedure provided below. 4. PLAY mode 1) Check that the preset state is set. 2) Input the square wave or sine wave to the TP31 (PH-S), TP32 (PH-T) and the TP (GND). 3) Press the jog lever (S703) will move the slider (NR) once towards the side REV and then to the side FWD. Move the DIRECTION switch (S702) according to this timing will set the PLAY mode (side FWD). Press the jog lever (S703) another time for a second and move the DIRECTION switch (S702) according to the movement of the slider (NR) will set the PLAY mode (side REV). – MAIN BOARD (Side A) – PUSH – Y/ x r > .

Preset state To set the PLAY, FF, REW modes, the preset state must be set. 1) Check that the slider (NR) and the DIRECTION switch (S702) are set to the center position. If not, set the preset state as follow. 2) Move the DIRECTION switch (S702) to the side, which the slider (NR) is facing. 3) The slider (NR) will move when the regulated power supply switch is set to OFF once and then set to ON. Move the DIRECTION switch (S702) according to this timing and set to the center position. 13942296513 13942296513 Note 1: If the above fails, perform from preset again. Note 2: When using headphones, the timing for move the DIRECTION switch (S702) can be determined from the beep sound. TEL TEL 1. Setting 1) Refer to “3. DISASSEMBLY”, and remove the MAIN board. 2) Connect the MAIN board to the motor (M601) and the plunger (PM701) using jumper wires. These can be connected easily with the use of the extension tool (Part No. 1-769-143-11) (ten in one set). 3) Short the lands by solder. 4) Connect the AF oscillator to the TP31 (PH-S), TP32 (PH-T) and the TP (GND). 5) Supply 1.3 V to the battery terminals using the regulated power supply. 3. FF, REW modes 1) Check that the preset state is set. 2) Input the square wave or sine wave to the TP31 (PH-S), TP32 (PH-T) and the TP (GND). 3) Move the jog lever (S703) toward [FF] or [REW]. http://www.xiaoyu163.com QQ 376315150 892498299 Slider (NR) Rotation system Rotation system during PLAY. gear (NR) (FWD : left side/ REV : right side) idler gear (A) (side S) idler gear (A) (side T) gear (REEL) (side S) gear (REEL) (side T) motor pulley slider (NR) cam gear clutch assy (F) idler gear (B) TEL TEL gear (Y) side F side R center insert flywheel (N) gear (FR) idler gear (A) (REW: right side) (side S) gear (REEL) (side S) gear (FR) (FF: left side) gear (REEL) (side T) motor pulley cam gear motor pulley cam gear clutch assy (F) gear (Y) gear (Y) clutch assy (F) reverse pulley insert flywheel (N) www insert flywheel (R) . reverse pulley insert flywheel (N) insert flywheel (R) xiaoy u163. com –4– http://www.xiaoyu163.com 376315150 892498299 376315150 892498299 Rotation system during REW.
