The service manual was very usable and clear enough to see the individual values of all of the components (unlike some of the service manuals I have gotten in the past from web sites similar to this one). The price was right and the information was greatly appreciated. It helped me with an otherwise very difficult repair. It was much needed and appreciated. A faster turn around on my order would be nice, but I understand the constraints on your staff's time. Thank you for your service.

SECTION 2 SERVICE NOTE
[Service Mode]
The service mode enables to operate the mechanism of WM-EX2000 while the MAIN board is opened. Rotation of the idler gear (A) (S side) is detected using the photoreflector (PH702) in the WM-EX2000. PH702 is located on the MAIN board, therefore the rotation of the idler gear (A) (S side) cannot be detected by PH702 when the MAIN board is removed. As a result, the motor cannot be controlled and cannot run correctly. To repair the machine after the MAIN board is removed while the main power is turned on, follow the procedures as described below. 1. Setting 1) Remove the cabinets referring to section �3. DISASSEMBLY�. Open the MAIN board. 2) Connect the motor (M601) and the plunger solenoid (PM701) to the MAIN board using the jumper wires. When the extension jig (1-769-143-11) (10 wires as a set) is used, they can be connected easily. 3) Short the TAPE IN switch land (BP1) with solder. Input a square (or sine) wave of 10 Hz (at 1.3 Vp-p) to both PH IN T land (TP31) and PH IN S land (TP32) with jumper wire. 4) Connect DC 1.3 V from external regulated power supply to 3 and # terminals of the battery. 2. PRE-SET status The set must be in this state before the PLAY, FF and REW modes can be entered. 1) Make sure that the slider (F/R) is in the center position and that the F/R switch (S702) is in the center position. Make sure that the reel gear does not rotate by rotating the flywheel on the F side clockwise. If improper, place the set in the preset state according to the following instructions: 2) Repeat the step below some times to ensure the above conditions. * Pull away the trigger level from the plunger with tweezers or other means. Then rotate the flywheel on the F side clockwise. 3) Turn the stabilized power supply OFF once and then ON.
3. FF, REW modes 1) Check for �2. Preset state� and push the FF switch and the REW switch. 2) Move the F/R switch (S702) to the movement of the slider to enter the FF/REW mode. 4. PLAY mode 1) Check for �2. Preset state�. 2) Push the nN switch on the remote commander to move the lever (SW) toward the R side. With timing to this, move the F/ R switch (S702) to enter the PLAY (R side) mode. Note 1: If failed, retry from the preset state. Note 2: The nN, x, FF, and REW switches on the remote commander should be used whenever possible.
