48. B6007 2 Motor Unit LOADING CARRIAGE CXB5903 6 ADJUSTMENT 6 1 CD ADJUSTMENT 1 Precautions This unit uses a single power supply 5V for the reg ulator The signal reference potential therefore is connected to VREF approx 2 1V instead of GND If VREF and GND are connected to each other by mis take during adjustments not only will it be impossi ble to measure the potential correctly but the servo will malfunction and a severe shock will be applied to the pick up To avoid this take special note of the fol lowing Do not connect the negative probe of the measuring equipment to VREF and GND together It is especially important not to connect the channel 1 negative probe of the oscilloscope to VREF with the channel 2 negative probe connected to GND Since the frame of the measuring instrument is usual ly at the same potential as the negative probe change the frame of the measuring instrument to floating sta tus If by accident VREF comes in contact with GND immediately switch the regulator or power OFF Always make sure the regulator is OFF when connect ing and disconnecting the various filters and wiring required for measurements Before proceeding to further adjustments and mea surements after switching regulator ON let the player run for about one minute to allow the circuits to stabi lize Since the protective systems in the unit s software are rendered inoperative in test mode be very careful to avoid me
