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 50f ~70f (30c ~ 40c) higher than pb solder. please use a soldering iron with temperature control and adjust it to 700f 20f (370c 10c). 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 1100f (600c). 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 the 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 turers 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. 3 kx-ts500fxb / kx-ts500fxc / kx-ts500fxh / kx-ts500fxr / KX-TS500FXW free datasheet http://www..net/

2 for service technicians ics and lsis are vulnerable to static electricity. when repairing, the following precautions will help prevent recurring malfunctions. 1. cover the plastic parts boxes with aluminum foil. 2. ground the soldering irons. 3. use a conductive mat on the worktable. 4. do not touch ic or lsi pins with bare fingers. 3 caution danger of explosion if battery is incorrectly replaced. replace only with the same or equivalent type recommendenced by the manufacturer. dispose of used batteries according to the manufactures instructions. 5 kx-ts500fxb / kx-ts500fxc / kx-ts500fxh / kx-ts500fxr / KX-TS500FXW free datasheet http://www..net/

12 circuit operations 12.1. telephone line interface and pulse dial circuit when the hook switch sw1 is on (off-hook), the circuit is closed, and current is supplied to the base of q2 via the diode bridge d17 and q2 is on ? q1 is on (off-hook condition). q1 and q2 are the dial pulse generating circuits, and are driven by the dialer (ic1), when the dialer pin 10 of ic1 is low ? q2 is off and q1 is off (break). if port pin 10 is high ? q2 is on ? q1 is on (make). 12.2. tone dial circuit function: the tone dialing circuit consists of a dtmf (dual tone multi frequency) signal generator (outputted from pin 25 of the ic1) for tone dialing, and also a circuit for outputting the signal to line. the dtmf circuit identifies inputs from the 12 keys (1,2,3,4,5,6,7,8,9,0, and #) by means of a total of seven frequencies, that is four low frequencies (low group) and three high frequencies (high group). circuit description: when a dial key is pressed, a dtmf signal is output from pin 25 of ic1 as an analog synthetic wave. the signal flow to the line is as follows. pin25ofic1 ? q3 ? r9 ? q1 ? tel line. the dtmf signal is sent to the line via the following path. q3 is an amplifier which is used to output the signal to line. shown below is the signal flow used to output the dtmf signal from the handset as a monitor tone when a dial key is pressed. pin 3 of ic1 ? r24 ? c15 ? handset speaker. the signal combination and frequency corresponding to each dial key is shown on next page. 16 kx-ts500fxb / kx-ts500fxc / kx-ts500fxh / kx-ts500fxr / KX-TS500FXW free datasheet http://www..net/

12.3. ringer circuit circuit operation: the bell signal passes through c1 (r1) ? pin 21 of ic1 detect the bell signal. the ring signal is output from pin 8 of ic1, and its volume is adjusted in 3 steps (h-l-off) by sw3 then impressed on the ceramic sound generator, and so is generated. r15,r16.............bellsensitivityadjustment below content (inside ruled line) is information only for service correspondence. usually, the default setting is digit 6. 18 kx-ts500fxb / kx-ts500fxc / kx-ts500fxh / kx-ts500fxr / KX-TS500FXW free datasheet http://www..net/
12.4. power circuit and redial back-up circuit function: this set is powered from the line. when it is an off-hook status, tel line ? d17 ? q1 ? r9 ? pin 27 of ic1 (to become the power supply for ic1 speech network). the voltage from the line is turned into a constant voltage by d2 and then supplied to the ic1, reset circuit. through tel line ? r1 ? r3 ? d17 ? r14 to become the power supply for ic1, and the redial back-up will be done. 19 kx-ts500fxb / kx-ts500fxc / kx-ts500fxh / kx-ts500fxr / KX-TS500FXW free datasheet http://www..net/
