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!
Unleaded solder is more viscous (sticky, less prone to ﬂ ow)
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.
NOTE OF REPLACING THE IC3601 ON THE
D VIDEO BOARD
Replacement of IC3601 on the D VIDEO board used in this set
requires a special tool.
NOTE OF REPLACING THE IC3511, IC3513, IC3514
AND IC3610 ON THE D VIDEO BOARD
IC3511, IC3513, IC3514 and IC3610 on the D VIDEO board can-
not exchange with single. When these parts on the D VIDEO board
are damaged, exchange the entire mounted board.
NOTE OF REPLACING THE IC5002 AND IC5202 ON
THE DSP BOARD
IC5002 and IC5202 on the DSP board cannot exchange with sin-
gle. When these parts on the DSP board are damaged, exchange the
entire mounted board.
NOTE OF REPLACING THE IC8001 AND IC8013 ON
THE NETWORK BOARD
IC8001 and IC8013 on the NETWORK board cannot exchange
with single. When these parts on the NETWORK board are dam-
aged, exchange the entire mounted board.
