SERVICING NOTES

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.

DO NOT REPLACE THE LITHIUM BATTERY

(US and Canadian models only)

The LITHIUM BATTERY for US and Canadian models cannot

be replaced. If it is necessary to replace the LITHIUM BATTERY,

BOARD REPLACING

CN301, IC401 and IC402 on the MAIN board cannot exchange

with single. When these parts are damaged, exchange the complete

mounted board.

NOTE OF WiFi MODULE REPLACING
