6. Connect the TV only to an AC power source with voltage and frequency as specified on the back cover nameplate. 7. Do not attempt to connect or disconnect any wires while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts. 8. To protect against shock hazard, use an isolation transformer.
4-3-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube, so that external degaussing after moving the TV should be unnecessary. 8ut the receiver must be properly degaussed upon installation . The degaussing coil operates far about 1 second after the power is switched ON. If the set is moved or turned in a different direction, the power should be OFF far at least 10 minutes. If the chassis or parts of the cabinet become magnetized, poor colar purity will result. If this happens, use an external degaussing coil. Slowly move the degaussing coil around the faceplate of the picture tube and the sides and front of the receiver. Slowly withdraw the coil to a distance of about 6 feet before turning power OFF. If colar shading persists, perform the following Colar Purity and Convergence adjustments.
4-3-3 High Voltage Check
CAUTION : There is no high voltage adjustment chassis. The 8+ power supply should be +8.5 volts (see table 1). 1. Connect a digital voltrneter to the second anode of the picture tube. 2. Turn on the TV. Set the 8rightness and Contrast controls to minimum (zero beam current). 3. Adjust the 8rightness and Contrast controls to both extremes. Ensure that the high voltage does not exceed Maximum High voltage (see table 1 ) under any conditions.
INCH 10 +8 (Volts) 8.5 Maximum High Voltage 23 KV

+8 and Maximum High voltage
4-3-4 PIF VCO Adjustment
1. Input 189.25MHz signal(O7ch) to antenna. Use a pattern generator. or tune in the active station in your area. 2. Adjust VCO in the service mode.
