Using the following Extension Cables, place the unit as shown for check and service.
No. PART NUMBER
1 VUVS0007 12Pin Extension Cable
2 LSUA0020 20Pin Extension Cable
3 LSUA0021 26Pin Extension Cable
4 LSUA0021 26Pin Extension Cable
NOTE:
1. When using the cassette tape:
(1) Be sure to remove a cassette lid cover of cassette tape.
(2) Be sure to install the Lock Screw to Cassette Up Unit. After servicing, be sure to remove the Lock Screw.
Refer to "How to Hold the Cassette Up Unit in the Down Position without Cassette Cover Installed," page 1-14.
(3) Select the H. Safety Defeat in SERVICE MODE. Refer to "Service Mode Specification," page 1-18.
Or, connect a silicon diode on component side of the Main C.B.A. as shown to defeat safety function.
(Since Takeup Reel sensor, located on Main C.B.A. does not work when opening Main C.B.A., the mechanism does not
work (Reel lock). Therefore, make sure to defeat Safety function.)
2. Use extreme care so as not to apply any excessive pressure to the Cylinder/Head Amp F.P.C. After servicing, be sure to place
it correctly. Refer to "Cylinder Ass'y" in "Disassembly/Assembly Procedures of Mechanism," page 2-20.
3. The LCD open/close SW. is for changing between LCD Display or EVF Display. When turning on LCD Display, place some paper
or tape, etc. on LCD open/close SW. so that this SW. stays ON.
4. Use a grounded ESD wrist strap while disassembling the Lens portion.
5. Use extreme care when unplugging or plugging in connectors.
Note: marked parts are supplied as service fixtures.
