Be careful not to apply force on the conductor when soldering or unsoldering. SAFETY CHECK-OUT After correctin

9、g the original service problem, perform the follow- ing 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

10、 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.

11、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 0.7

12、5 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 2 V AC range are suitable. (See Fig. A) 1.5 k0.15 F AC voltmeter (0.75 V) To Exposed Metal Par

29、DVD data stored in the RAM to initial conditions. Execute this mode when returning the set to the customers. Procedure: 1. Press the ?/1 button to turn the power on. 2. Press the x and VOLUME buttons simultaneously and hold down (around 5 seconds). 3. The message “COLD RESET” appears on fl uorescent

30、 indica- tor tube, then becomes standby states. DEMO MODE This mode let you lock the disc tray. When this mode is activated, the disc will not eject when the Z button is pressed. The message “LOCKED” will be displayed on the fluorescent indicator tube. Procedure: 1. Press the ?/1 button to turn the

31、power on. 2. Press the FUNCTION button to select the “BD/DVD”. 3. Press the x and Z buttons simultaneously and hold down until “DEMO ON” or “DEMO OFF” displayed on the fluores- cent indicator tube (around 5 seconds). S-AIR ID SETTING CHANGE Procedure: 1. Press the ?/1 button to turn the power on. 2.

32、 Press the FUNCTION and VOLUME + buttons simultane- ously and hold down (around 5 seconds). 3. S-AIR ID setting is changed (A B C A.). PANEL TEST Procedure: 1. Press the ?/1 button to turn the power on. 2. Press button in order of the RETURN 0 0 1 SUBTITLE on the remote commander (Make the interval

33、when each button is pressed within two seconds). 3. All segments in fl uorescent indicator tube are lighted up. And half segments in fl uorescent indicator tube are lighted up, oth- ers half segments in fl uorescent indicator tube are lighted up, then LEDs and all segments in fl uorescent indicator

34、tube are lighted up. This operation is repeated. 4. When all segments in fl uorescent indicator tube are lighted up in the state of step 3, press the VOLUME + button on the remote commander and model information is displayed on the fl uorescent indicator tube. Each time the VOLUME + button on the re

35、mote commander is pressed, the display changes from destination information, STR version, SYS version, UI version, BDLIB version, ST version, TA version, DSP version, TM version, CEC version, SAIR version, PF version in this order, and returns to the mod- el information display. Each time the VOLUME

36、 button on the remote commander is pressed, the version and date are switched. 5. In the state of step 3, press the FUNCTION button on the remote commander and “K 0” is displayed on the fluorescent indicator tube. “K 0” value increases whenever a button on the set is pressed. However, once a button

37、has been pressed, it is no longed taken into account. All buttons on the set are pressed, “OK” and “K 7” are alter- nately displayed on the fluorescent indicator tube. 6. To release from this mode, press the ?/1 button. AMP TEST Procedure: 1. Press the ?/1 button to turn the power on. 2. Press butto

38、n in order of the RETURN 0 1 1 SUBTITLE on the remote commander (Make the interval when each button is pressed within two seconds). 3. The message “MEASURE” appears on the fluorescent indica- tor tube and enter the AMP test mode. 4. Press the BLUE button on the remote commander, the state of D.C.A.C

39、. microphone is displayed on the fl uorescent indica- tor tube. * $ * : Either of “IN”/“NON” is displayed by the state of detection of the microphone. : Either of “OK”/“NG” is displayed by the state of digital audio data input. $ : Microphone input audio data A/D value (0 255). 5. Press the MUTING b

40、utton on the remote commander, “VOL N” (The change in the volume is usual)/“VOL MSM” (The change in the volume is a switch of MIN/1/20/MAX) can be switched. 6. Press the SUBTITLE button on the remote commander, the message “VACS ON” or “VACS OFF” appears on the fl uores- cent indicator tube and thus

41、 the VACS on/off are changed. 7. To release from this mode, press the ?/1 button. BD SERVICE MODE Note: The operation in this mode must use a remote commander. Setting method of the BD service mode: 1. Press the ?/1 button to turn the power on. 2. Press button in order of the RETURN 0 2 1 SUBTITLE o
