SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check 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 TEST 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 microampers.). 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. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. 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 lowvoltage 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 2 V AC range are suitable. (See Fig. A)

SECTION 4 TEST MODE

1. PRECAUTIONS FOR USE OF TEST MODE
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 [EJECT] 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 [EJECT] button after pressing the [MENU/NO] button and the rotation of disc is stopped. 1-1. Recording laser emission mode and operating buttons Continuous recording mode (CREC MODE) Laser power check mode (LDPWR CHECK) Laser power adjustment mode (LDPWR ADJUS) Traverse (MO) check (EF MO CHECK) Traverse (MO) adjustment (EF MO ADJUS) When pressing the [REC] button. r

2. SETTING THE TEST MODE

The following are two methods of entering the test mode. Procedure 1: While pressing the [AMS] knob and [] button, connect the power plug to an outlet, and release the [AMS] p knob and [] button. p When the test mode is set, [Check] will be displayed. Turn the [AMS] knob switches between the following four groups; N [Check] N [Adjust] N [Service] N [Develop] N. n n n n n Procedure 2: While pressing the [AMS] knob, connect the power plug to the outlet and release the [AMS] knob. When the test mode is set, TEMP CHECK will be displayed. By setting the test mode using this method, only the Check group of method 1 can be executed.
3. EXITING THE TEST MODE Press the [REPEAT] button. The disc is ejected when loaded, and Standby display blinks, and the STANDBY state is set. 4. BASIC OPERATIONS OF THE TEST MODE All operations are performed using the [AMS] knob, [YES] button, and [MENU/NO] button.
The functions of these buttons are as follows.
