ADJUSTMENT O Safety Precautions 1. It is safe to adjust after using insulating transformer between the power supply line and chassis input to prevent the risk of electric shock and protect the instrument. 2. Never disconnect leads while the TV receiver is on. 3. Don't short any portion of circuits while power is on. 4. The adjustment must be done by the correct appliances. But this is changeable in view of productivity. 5. Unless otherwise noted, set the line voltage to 110~240Vac !10%, 50/60Hz. 6. The adjustment of TV should be performed afther warming up for 20 minutes.
