2. DISASSEMBLY NOTE FOR REPAIR • Make sure that the flat cable and flexible board are not cracked of bent at the terminal. Do not insert the cable insufficiently nor crookedly. • When remove a connector, don't pull at wire of connector. It is possible that a wire is snapped. • When installing a connector, don't press down at wire of connector. It is possible that a wire is snapped. • Do not apply excessive load to the gilded flexible board. Cut and remove the part of gilt which comes off at the point. (Be careful or some pieces of gilt may be left inside) DISCHARGING OF THE ST-175 BOARD'S CHARGING CAPACITOR (C5206) The charging capacitor (C5206) of the ST-175 board is charged up to the maximum 300 V potential. There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be discharged as described below. Preparing the Short Jig To preparing the short jig, a small clip is attached to each end of a resistor of 1 kΩ /1 W (1-215-869-11). Wrap insulating tape fully around the leads of the resistor to prevent electrical shock. 1 kΩ/1 W Note: High-voltage cautions Discharging the Capacitor Short-circuit between the two points with the short jig about 10 seconds. To avoid the spark with the metal plate, wrap the short jig with the insulation tape. Wrap insulating tape.
