SAFETY PRECAUTIONS INTRODUCTION SAFETY NOTICE This manual provides service information for the adjustments of mechanical and electrical operations. Due to design modifications, the servicing procedures and data given in this manual are subject to possible change without prior notice. Before returning VCR to the customer a safety check of the entire VCR should be made.
2. Hot Check The test sequence, with reference to the measuring circuit in the figure is as follows: (1) With switch S1 open, connect the VCR to the measuring circuit. Immediately after connection, measure the leakage current using both positions of switch S2 and with the switching devices in the VCR in all of their operating positions.
CONNECTION Now that you’ve completed the antenna connections to your VCR, you’re ready to connect the VCR to the TV. Because every television is different (especially older model TVs), your VCR may need to be connected in a variety of ways. See the Owner’s Manual for Instruction Information ON: • Determining if you need a splitter, • Connecting TVs with audio and video inputs. Connecting separate antennas (UHF/VHF) Connecting the Television To connect separate UHF/VHF antennas to the VCR: 1.

SCHEMATIC DIAGRAMS NOTE 1. Each voltage should be within ± 20% of the DC voltages measured with a digital voltmeter. 2. The voltages parenthesised on SP recording mode. While those without parenthesised on SP play back mode. 3. Waveforms were taken with standard color bar signal. 4. TP6A, etc. show Test Points. 5.
