In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that
contains lead.

We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn),
Silver (Ag), and Copper (Cu).

This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder.

• PbF solder has a melting point that is 50 °F ~ 70 °F (30 °C ~ 40 °C) higher than Pb solder. Please use a soldering iron with

temperature control and adjust it to 700 °F ± 20 °F (370 °C ± 10 °C).

• Exercise care while using higher temperature soldering irons.: 

Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.

• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100 °F (600 °C).
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the

opposite side (See the figure below).

There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac
turer's specific instructions for the melting points of their products and any precautions for using their product with other 
materials. 
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

When discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

LCD data are output from pin C19 of IC101 to LCD module.
LCD contrast is set by electronic control in LCD module.
+3.3V of the power supply voltage is pressurized about four/three times in the LCD module and used as LCD driving voltage
(approx. 10V).
The driving voltage is observed at pin12(VLCDIN) of CN1.
The lighting of the backlight is controlled by Q403.
The PWM (Pulse Width Modulation) signal is output from IC101 (pin U13) pin and the brightness is changed according to its duty
ratio.
