SAFETY CHECK-OUT
General
Power requirements Sony AC Power Adaptor AC-DA300 (supplied) connected at the DC IN 12 V jack : 120V AC, 60Hz (US model) Power consumption 20 W Operating temperature 5 ░C to 35 ░C (41░F to 95░F) Operating humidity 30% to 85% Dimensions Approx. 280 О 80 О 290 mm (111/8 О 31/4 О 111/2 inches) (w/h/d, including projecting parts and controls) Mass Approx. 2.5 kg (5 lb. 8 oz) Supplied accessories AC power adaptor AC-DA300 Remote commander RMT-DA300 (1) Size AA (R6) batteries (2) Design and specifications are subject to change without notice.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

LEAKAGE
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

2. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement и Never reuse a disconnected chip component. и Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing и Keep the temperature of soldering iron around 270░C during repairing. и Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). и Be careful not to apply force on the conductor when soldering or unsoldering. CAUTION Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.

5. PRECAUTIONS FOR USE OF TEST MODE
1. As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is stopped before setting and removing it. Even if the 6 button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating. Be sure to press the 6 button after pressing the N button and the rotation of disc is stopped. 2. The erasing-protection tab is not detected in the test mode. Therefore, operating in the recording laser emission modes suchas continuous resord mode, traverse adjustment mode, etc., the recorded contents will be erased regardless of the position of the tab. When using a disc that is not to be erased in the test mode, be careful not to enter the continuous recording mode and traverse adjustment mode.

Temperature Compensation Offset Adjustment
Save the temperature data at that time in the non-volatile memory as 25 ░C reference data. Note : 1. Usually, do not perform this adjustment. 2. Perform this adjustment in an ambient temperature of 22 ░C to 28 ░C. Perform it immediately after the power is turned on when the internal temperature of the unit is the same as the ambient temperature. 3. When D101 has been replaced, perform this adjustment after the temperature of this part has become the ambient temperature. Adjusting Method : 1. Press the , buttons and display "TEMP ADJUST". 2. Press the n button and select the "TEMP ADJUST" mode. " and the current temperature data will be 3. "TEMP = displayed. 4. To save the data, press the n button.
