UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!
• Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder
B
It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

SAFETY CHECK-OUT
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.
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 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)

Procedure:
1. Press `/1 button to turn the power on.
2. Press the FUNCTION button to select “AM”.
3. Press `/1 button to turn the power off.
4. Press two buttons `/1 and INPUT SELECTOR at the same
time, and the display changes to “AM 9k Step” or “AM 10k Step”, and thus the channel step is changed over.
5-3. Version Check
Procedure:
1. Press the VOLUME + button with all segment lit, and “RACK” is displayed.
2. Whenever VOLUME + button is pressed, the category is displayed in the way below.
t RACK t NA t MC t SYS t UI t ST t TA t TM
3. When the INPUT SELECTOR button is pressed when each category is displayed, the version of the category is displayed.
4. To exit this mode, press the `/1 button.
4. Volume Test
Procedure:

2. Press the INPUT SELECTOR button, and “DVD” is displayed.
3. Press the VOLUME – button, and “VOLUME MIN” is displayed for second times.
4. Press the VOLUME + button, and “VOLUME MAX” is displayed for second times.
5. When the `/1 button is pressed twice, the test mode is released. At that time, cold reset is done as for the set.
5. Panel Test
• This mode is used to check the display, key and software version.
5-1. Display Check
Procedure:
1. Enter the test mode.
2. Press the VOLUME + button, and “PANEL” is blinking.
