1 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 although, with some precautions, standard Pb solder can also be used. 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). In case of using high temperature soldering iron, please be careful not to heat too long. · PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (600°C). · If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and be sure that any remaining is melted prior to applying the Pb solder. · 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).
1.1.
Suggested PbF Solder
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.

10.4. Check the RF Unit
10.4.1. Defective Unit Check
The defective unit should be checked using the HS of Regular unit (working) and BS of Regular unit (working). Both* of Regular unit (working) are required as the defect may be either in the handset or the base of the defective unit. For a defective BASE UNIT, place HS of Regular unit (working) on the cradle of the unit and check to see that the handset links with the base. To confirm that they do link, lift handset off the cradle and press TALK button. A beep is heard and in use/charge LED's of the base unit should turn on. For a defective HANDSET UNIT, place HS on the cradle of the BS of Regular unit (working) and check to see that the HS links with the base. Again, press TALK button. A beep is heard and in use/charge LED's of the BS of Regular unit (working) should turn on.
See RF Check Flowchart (P.21). See Check Table for RF Unit (P.22). Note: *KX-TG2258 with marks HS JIG/BS JIG can be used only for troubleshooting. However, regular production set also can be used as a JIG.
10.4.2. Converting a Regular Production Unit to a JIG
Both base unit and handset unit have two modes: TEST POWER LOW mode and NORMAL POWER mode even a Regular production unit. Each unit can be used as a JIG by changing the original NORMAL POWER mode to TEST POWER LOW mode. · NORMAL POWER mode. In this mode both base unit and handset unit can be used as a regular set. · TEST POWER LOW mode, when production unit has been changed into a jig and will be used to check RF link. In this mode it is for checking if the sensitivity of RF unit for both base unit and handset unit are good or not. Procedure as follows to enter this mode. (1) Press "Soft Left" and " " of the handset simultaneously, and keep it (10CH is taken for example). (2) Place the handset unit on the cradle of the base unit. (A long beep sounds, and the display is not changed.) As shown in below a) HANDSET, b) BASE UNIT a) HANDSET

The voice signal from the base unit is output to DSP (33) (HSSOUT). This signal is led to the headset jack (CN203) and DSP (44) (HSMIP). The signal input to DSP (44) is inverted and output to DSP (34) (LOUTO).The signal through the headset jack is inverted, then output from DSP (34) to drive the speaker. When the headset is inserted to the jack, the voice signal is cut at the jack, so the sound does not come out from the speaker, but from the headset only.
17.7. Reset Circuit
Fuction: This circuit is used to initialize the DSP when the battery is inserted into the unit. Circuit Operation: The power of the Handset is supplied from the battery. When the battery is inserted, Regulator (IC1) shifts 2.6 V to DSP (Vcc PLL) so that the voltage of DSP will be stable. As a result, the reset signal occurs inside the DSP.

22.1. Preparation
· PbF (: Pb free) Solder · Soldering Iron Tip Temperature of 700°F ± 20°F (370°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil. · Flux Recommended Flux: Specific Gravity 0.82. Type RMA (lower residue, non-cleaning type) Note: See ABOUT LEAD FREE SOLDER (PbF: Pb free) (P.4).
22.3. Removing Solder from Between Pins
1. Add a small amount of solder to the bridged pins. 2. With a hot iron, use a sweeping motion along the flat part of the pin to draw the solder from between the adjacent pads.
22.2. Procedure
1. Tack the flat pack IC to the PCB by temporarily soldering two diagonally opposite pins in the correct positions on the PCB.
Be certain each pin is located over the correct pad on the PCB. 2. Apply flux to all of the pins on the IC.
3. Being careful to not unsolder the tack points, slide the soldering iron along the tips of the pins while feeding enough solder to the tip so that it flows under the pins as they are heated.
