• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

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)

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 viscou-s (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.

Connect the SA-WSLF1H to the HCD-LF1H. Set up the system so that the infrared signal from IR transmitter (DIR-T1) can be received by the
rear speaker (SA-TSLF1H).

The IR status indicator of this unit (SA-TSLF1H) lights in red when the power of the SA-WSLF1H receiving waiting state (when data is not
transmitted.) When the power of the SA-WSLF1H is turned on and the infrared signal from IR transmitter (DIR-T1) is received by this unit (SA-
TSLF1H), the IR status indicator of this unit (SA-TSLF1H) lights in green.

1. Connect a spectrum analyzer and an oscilloscope to the connector CN7301 pin-1 of DIAT PD board.

2. Confirm that the spectrum is displayed as shown in Fig. 1 on spectrum analyzer. Also confirm that the waveform as shown in Fig. 2

is  displayed.
