1 Warning BL-C111A/BL-C131A 1.1. Battery Caution Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to following caution: Disposal or transportation of lithium batteries should be performed by permitted, in accordance with federal, state and local guidelines. A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong packaging. Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate disposition. This is a good practice for all types of commercial or industrial waste. When the lithium battery is exchanged, the clock settings are cleared. In this case, make clock settings again. Recommend Type Number: CR2032/H9B (BAT1) Manufactured by MATSUSHITA 1.2. About Lead Free Solder (PbF: Pb free) Note: 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. Caution • 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 figure, below). 3

Warning
1.1.
Battery Caution
Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to following caution:
Disposal or transportation of lithium batteries should be performed by permitted, in accordance with federal, state and local
guidelines.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong
packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate dis-
position. This is a good practice for all types of commercial or industrial waste.
When the lithium battery is exchanged, the clock settings are cleared. In this case, make clock settings again.

About Lead Free Solder (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con-
tains 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.
Caution
• 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 tem-
perature 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 figure, below).
