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 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.

SERVICING NOTES
[AMP Board Input Signal Check Procedure]
Note 1: 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).
Note 2: 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.
Check procedure:
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.

[Note on Assembling the SA-TSLF1H]
When assembling the PD block, be sure to follow the steps below.
Otherwise, the capacitor may break and a product failure may result.
3. Install the LOUDSPEAKER (2.5 cm) (SP902) with the
+BVTP3 ×8 screw.
2. Take in the capacitor to the main unit.
Check that the capacitor does not touch screw A inside the
main unit.
1. Check that screwA is +BVTP3 ×14, and install the PD block
to the main unit.
