IMPORTANTINFORMATION ABOUTLEAD FREE, (PbF), SOLDERING
If leadfree solderwas usedinthe manufacture of this product the printedcircuit boards will be
markedPbF.
Standardleaded, (Pb), soldercanbe usedas usual on boards without the PbF mark.
Whenthis mark does appearplease readand followthe special instructions describedinthis
manual on the use of PbF and howit might be permissible touse Pbsolderduring service and
repairwork.
1. ABOUT LEAD FREE SOLDER (PbF: Pb free)
Note:
Inthe information below, Pb, the symbol forleadinthe periodic table of elements, will referto
1

standardsolderorsolderthat contains lead.
We will use PbF solderwhendiscussing the leadfree solderusedinourmanufacturing process
whichis made fromTin, (Sn), Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufacturedusing leadfree solderwill have PbF stampedon
the PCB. Forservice and repairwork we suggest using the same type of solderalthough, with
some precautions, standardPbsoldercanalsobe used.
Caution
-PbF solder has amelting point that is50° ~ 70° F, (30° ~ 40°C)
higher than Pb solder. Please use asoldering iron with
temperature control and adjust itto 700° ± 20° F, (370° ± 10°C). In
case of using high temperature soldering iron, please be careful
not to heat too long.
-PbF solder will tend to splash ifitisheated much higher than its
melting point, approximately1100°F, (600°C).
-Ifyou must use Pb solder on aPCB manufactured using PbF
solder, remove as much of the original PbF solder as possibleand
be sure that anyremaining ismelted prior to applying the Pb
solder.
-When applying PbF solder to doublelayered boards, please check
the component side for excess which mayflow onto the opposite
side (See figure, below).
1.1. SUGGESTEDPbF SOLDER
There are several types of PbF solderavailable commercially. While this product is
manufacturedusing Tin, Silver, and Copper,(Sn+Ag+Cu), you canalsouse Tinand Copper, (Sn+
Cu), orTin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufacturer’s specific
instructions forthe melting points of theirproducts and anyprecautions forusing theirproduct
withothermaterials. The following leadfree (PbF) solderwire gauge are recommendedfor
service of this product: 0.3mm, 0.6mm and 1.0mm.

1.2. HOWTO RECOGNIZE THATPb FREE SOLDERISUSED
“PbF” is markedon the PCB toshowthat Pbfree solderis used.(See the figure below.)

2. FOR SERVICE TECHNICIANS
ICs and LSIs are vulnerable tostatic electricity.
Whenrepairing, the following precautions will helpprevent recurring malfunctions.
4

1. Cover the plasticparts boxes with aluminum foil.
2. Ground the soldering irons.
3. Use aconductive mat on the worktable.
4. Donot touch ICor LSI pins with bare fingers.
3. GENERAL DESCRIPTION
KX-TDA0174 (SLC16) is mountedintoa free slot of TDA100/200 system. Upto16 SLT canbe
randomlyconnectedbyusing SLC16 card. It does not have LPR onboard, and it is controlled
completelybyMPR.

Fastening Amphenol Type Connector
Anamphenol 57JE type connectoris usedon some of the optional sevice cards.
To connect anamphenol connector, use the spring latchorscrewtofix the upperpart and use

Velcro tape tofix the lowerpart of the connector.
AuxiliaryConnection forPowerFailure Transfer
AuxiliaryConnection forPowerFailure Transfer
Whenthe powersupplytothe HybridIP-PBX fails, powerfailure transfer(PFT) switches the
current connection tothe AuxiliaryConnection automatically. A specific SLT (determinedby
SystemProgramming) will be connectedtoselectedCO lines inthe event of systempower
failure. AuxiliaryConnection is requiredtoimplement this feature.
Connection
The following CO line and extension cards canbe usedforAuxiliaryConnections:
-Analog CO line cards: LCOT16 (4 PFT ports), and LCOT8 (2 PFT
port)
-Extension cards: MSLC16 (4 PFT ports), SLC16 (4PFT ports),
DHLC8(2 PFT port) and SLC8(2 PFT port)
