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.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead free 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 It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

ELECTRICAL ADJUSTMENT

Note:

Feed 9V dc power supply voltage. Set S502 INPUT SELECT to ANLOG side on feeding the power. (In case of it goes to DIGITAL side, the RF signal is not out without the optical input.) Be sure to use an oscilloscope with the 200MHz bandwidth or more.

Adjustment method:

Connect an oscilloscope to each TP501, 502, 503, 504, 505, 506, 507, 508, 509 or 510 on IF board, adjust with RV601 on TX board so that the output voltage goes to 1.10 ± 0.05 Vp-p.

For schematic diagrams. Note:

• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise specified.

•%: indicates tolerance.

• f : internal component.

• C : panel designation.

• A : B+ Line.

• H : adjustment for repair.

• Power voltage is dc 9 V and fed with regulated dc power supply from battery terminal.

•Voltages and waveforms are dc with respect to ground under nosignal conditions.

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

•Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.
