BELL DETECTION CIRCUIT1.Circuit Operation The signal waveform for each point is indicated below.The signal (low level section)input to pin 24of ASIC IC606on the digital board is read by ASIC and judged as a bell.TEL LINE →PC205(1,2-4)→IC606(24)7.3.6.4.4. CALLING LINE IDENTIFICATION CIRCUIT1.Function This unit is compatible with the Caller ID service offered by your local telephone company.To use this feature,you must subscribe to a Caller ID service.The data for the caller ID from the telephone exchange is sent during the interval between the first and second rings of the bell signal.The data from the telephone exchange is a modem signal which is modulated in an FSK (Frequency Shift Keying)format.Data “0”is a 1200Hz sine wave,and data 1a 2200Hz sine wave.There are two type of the message format which can be received:i.e.the single data message format and multiple data message format.The multiple data format allows to transmit the name and data code information in addition to the time and telephone number data.When there is multiple data in the unit,the name or telephone number are displayed. 2.Circuit Operation The caller ID signal input from TEL LINE is processed with MODEM (IC602).Refer to CHECK SHEET (P.85)for the route of caller ID signal.KX-FL503TKKX-FL503TKKX-FL503TK7.3.6.4.5. LINE AMPLIFIER AND SIDE TONE CIRCUIT1. Circuit OperationThe reception signal output from the line transformer T200is input to pin(6)of IC203via R212,C215and then the signal is amplified at pin(7)of IC203and sent to the reception system at8.1dB.The transmission signal goes through C218,R222and enters IC203-pin(2),where the signal is amplified to about17.5dB.Then,it is output from pin(1)of IC203and transmitted to T200via C239,R231and R230.Without a side tone circuit,the transmission signal will return to the reception amplifier via R212,C215.When the side tone circuit is active,the signal output from IC203pin(1)passes through C239,R225,R221,C228,R208and C216and goes into the amplifier IC203pin(5).This circuit is used to cancel the transmission return signal.The TX signal is output to the circuit analog the route from the IC2031pin→C239→R231→R230→T200→TEL LINE.However,if balance is lost in the bridge,a voltage occurs between the IC2036pin and5pin and a side tone results,because the balance cannot be maintained completely at all frequencies in the audio range some side tone always occur.7.3.6.4.6.

In this case, [MEMORY FULL] and its main cause (for example, “OUT OF PAPER”) are displayed on the LCD. Accordingly, by solving the main problem, [MEMORY FULL] can be canceled and the receiving problem can solved. The causes of the display errors are shown below.

(In most cases, this unit detects the CNG signal and can respond to CED or DIS.) (According to the ITU-T standard, the communication procedure is cancelled when there is no response from the other party within 35 sec, so that the other party releases the line.)(Cause and Countermeasure)As shown in the chart above, the total handshaking time must be reduced, but because of the long distance connection and linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be tried.(A)... As the 35 sec. count is started directly after dialing or directly after the START button has been pressed for models with aSTART button, the other party should be called manually, if possible. Another possibility is entering two pauses at the end of the auto dial number on the transmission side. Then the count start time can be delayed for 2 pauses (about 10 sec.).Cause 2:Erroneous detection because of an echo or an echo canceler.(Echo/Echo Canceler)The signal from FAX1 reaches FAX2 via stations 1 and 2, but the reflection signal at station 2 also returns via station 1 (echo).As the distance between station 1 and station 2 is far, the echo returns to FAX 1 at a max of 600 msec after transmission.There is a possibility that this signal is detected erroneously as the signal from FAX2. For a normal call, there is also a possibility that the echo of their own voice will make the call difficult to understand. For this reason, each station (station 1 and station 2) attaches echo cancelers (S1 and S2) for international lines or long distance lines. For the echo canceler, the level of the transmission signal from FAX 1 is compared with the level of the reception signal from FAX2. When the transmission signal is larger, S1 is closed while S2 is opened when it is smaller. In other words, for transmission from FAX1, S1 is closed and S2 is open, so that the echo does not return to FAX1.KX-FL503TK(Causes and Countermeasures)No. Countermeasure Side Echo Communication Problem Example Countermeasure Service Code1 Sending side Some time is needed to compare the level Add a dummy signal to the beginning Service code (521)of the receiving and sending signals for the of the training signal.

Therefore, travel to the customer´s location is not required. However, it is not possible to changeall the parameters remotely (PROGRAM MODE TABLE(P.74)). The function used to accomplish this is remote programming.First, in order to check the current status of the service code parameter, print out the setup list (code: 991) and the service list (code: 999) from the customer´s fax machine.Based on this, the parameters for the desired codes can be changed.The procedure for changing and listing parameters is described on ENTERING THE REMOTE PROGRAMMING MODE AND CHANGING SERVICE CODES(P.73). Also, before exiting the remote programming mode, it is advisable to obtain a new list to confirm that the changes were made correctly.Hint:Since the connected telephone is in use during the remote programming mode, it may be helpful to ask the customer to switch to the speakerphone. This frees the customer from the need to remain right next to the fax while you are making parameter settings. When finished, inform the customer. Also note that in very noisy locations where the DTMF tones are not audible, the remote programming function will not work.2.3.7.2.1.ENTERING THE REMOTE PROGRAMMING MODE AND CHANGING SERVICECODESCROSS REFERENCE:PROGRAM MODE TABLE (P.74)KX-FL503TK2.3.7.2.2.PROGRAM MODE TABLECode Function Set Value Default RemoteSetting 001 Set date and time mm/dd/yy hh:mm Jan/01/2001 NG002 Your logo --------- None NG003 Your fax number --------- None NG004 Transmission report mode 1:ERROR / 2:ON /3:OFF ERROR OK006 FAX ring count 1 to 9 rings (for ext. tam) 2 OK012 Remote TAM activation ON / OFF OFF / ID=11 NG013 Dialing mode 1:PULSE / 2:TONE TONE OK017 Melody Ringer BELL, MELODY A/B/C/D BELL NG022 Auto journal print 1:ON / 2:OFF ON OK023 Overseas mode 1:ON / 2:OFF OFF OK025 Delayed transmission ON / OFF OFF NG026 Auto CALLER ID list 1:ON / 2:OFF ON OK030 Silent FAX recognition ring 3 to 9 rings 3 OK031 Distinctive ring 1:OFF / 2:A / 3:B / 4:C / 5:D OFF OK037 Auto REDUCTION 1:ON / 2:OFF ON OK039 LCD contrast NORMAL / DARKER NORMAL NG040 Silent detection 1:ON / 2:OFF OFF OK041 Remote FAX activation code 1:ON / 2:OFF ON ID=*9 NG044 Memory receive alert 1:ON / 2:OFF ON OK046 Friendly receive 1:ON / 2:OFF ON OK048 Language 1:TURKISH / 2:ENGLISH TURKISH OK049 Auto disconnect 1:ON / 2:OFF ON NG058 Original setting 1:Normal / 2:Light / 3:Darker Normal NG068 ECM Selection 1: ON / 2: OFF ON OK070 FAX pager 1:ON / 2:OFF OFF NG076 FAX tone 1:ON / 2:OFF ON OK077 Auto answer mode 1:FAX only 2:TEL/FAX FAX only OK078 TEL/FAX ring 1 to 9 rings 2 OK079 Toner save 1:ON / 2:OFF OFF OK080 Set default YES / NO NO NG501 Pause time set 001~600 x 100msec 030 OK502 Flash time 01~99 x 10ms 70 OK503 Dial speed 1:10pps / 2:20 pps 10pps OK511 Vox sense 1:High / 2:Low High OK520 CED frequency select 1:2100Hz / 2:1100Hz 2100 OK521 International mode select 1:ON / 2:OFF ON OK522 Auto standby select 1:ON / 2:OFF ON OK523 Receive equalizer select 1 :0km / 2:1.8km / 3:3.6km / 4:7.2km 0 km OK524 Transmission equalizer select 1 :0km / 2:1.8km / 3:3.6km / 4:7.2km 0 km OK550 Memory clear --------- --------- NG551 ROM check --------- --------- NG552 DTMF signal tone test 1:ON / 2:OFF OFF OK553 Monitor on FAX communication 1:OFF / 2:Phase B / 3:ALL OFF OK554 Modem test --------- --------- NG555 Scanner test --------- --------- NG556 Motor test --------- --------- NG557 LED test --------- --------- NG558 LCD test --------- --------- NG561 Key test --------- --------- NG570 Break % select 1:61% / 2:67% 61% OK571 ITS auto redial time set 00~14 05 OK572 ITS auto redial line disconnection time set 005~999sec 065 OK573 Remote turn-on ring number 01~99 10 OK575 OFF-Hook alarm option 1:ON / 2:OFF ON OK590 FAX auto redial time set 00~14 05 OK591 FAX auto redial line disconnection time set 005~999sec 065 OK592 CNG transmit select 1:OFF / 2:ALL / 3:AUTO ALL OK593 Time between CED and 300bps 1:75ms / 2:500ms / 3:1sec 75ms OK594 Overseas DIS detection select 1:1st / 2:2nd 1st OK595 Receive error limit value set 1:5% / 2:10% / 3:15% / 4:20% 10% OK596 Transmit level set -15~00dBm 10 OK598 Receiving Sensitivity 20~48 43 OK599 ECM Frame size 1:256 / 2:64 256byte OK700 EXT.

(1:ERROR/2:ON/3:OFF)KX-FL503TK2.3.8.DIGITAL BOARD SECTIONWhen the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem.The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.)The first step is to check the power source. If there is no problem with the power supply unit, the problem may lie in the digital unit (main board).As there are many potential causes in this case (ASIC, DRAM, etc.), it may be difficult to specify what you should check first. Ifa mistake is made in the order of checks, a normal part may be determined faulty, wasting both time and money.Although the tendency is to regard the problem as a serious one (IC malfunction, etc.), usually most cases are caused by solder faults (poor contact due to a tunnel in the solder, signal short circuit due to solder waste).Note:1.Electrical continuity may have existed at the factory check, but a faulty contact occurred as a result of vibration, etc., duringtransport.2.Solder waste remaining on the board may get caught under the IC during transport, causing a short circuit.Before we begin mass production, several hundred trial units are produced at the plant, various tests are applied and any malfunctions are analyzed. (In past experiences, digital IC (especially SRAM, DRAM and ROM) malfunctions are extremely rare after installation in the product.)This may be repaired by replacing the IC, (DRAM etc.). However, the real cause may not have been an IC malfunction but a soldering fault instead.Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you have an oscilloscope, you can easily determine the problem site or IC malfunction by checking the main signal lines.Even if you don’t have such a measuring instrument, by checking each main signal line and r esoldering it, in many cases the problem will be resolved.An explanation of the main signals (for booting up the unit) is presented below.What are the main signals for booting up the unit?Please refer to DIGITAL BLOCK DIAGRAM (P.77).The ASIC (IC606) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored in the ROM (IC607), then follows the instructions for controlling each IC. All ICs have some inner registers that are assigned toa certain address.It is the address bus by which the ASIC designates the location inside each IC. And the data bus reads or writes the data in order to transmit the instructions from the ASIC to the ICs.These signal lines are all controlled by voltages of 3.3V (H) or 0V (L).KX-FL503TK 2.3.8.1.DIGITAL BLOCK DIAGRAMThe signal lines that must be normal for the system to boot up are listed here [List 1].For signal lines other than these, even if they malfunction, they do not directly affect booting up the system.KX-FL503TKIf these signals are in the normal condition, once the power is turned on, each IC repeatedly output 3.3 V(H) and 0 V(L). The following page shows NG and normal wave patterns.NG Wave PatternKX-FL503TK Normal Wave PatternsRemarks:For these reasons and the software sequence to boot up the unit, if you use an oscilloscope the judge whether a signal is OK or NG, you must check in the same order as in [List 1]. (IF the ASIC failed to access the ROM, the ASIC cannot access SRAM or DRAM normally.)The digital circuit actually operates according to the timing combinations of these signals. So, if the timing of these signals is even slightly off, the circuit will not operate normally. Even of the IC did malfunction, the output voltage level may become abnormal but the timing is accurate according to the specifications. (If oscillation is provided accurately.)Accordingly, the problem presented here is whether each IC outputs the correct signal. (See the I/O direction diagram on the next page.) In other words, is it constantly switching between 3.3 V (H) and 0 V (L) as described earlier.Note:All you have to do is check that the IC repeatedly outputs (H) 3.3 V and (L) 0 V.KX-FL503TKI/O and Pin No. DiagramKX-FL503TKAfter the power is turned on, the ASIC initializes and checks each IC.The ROM, SRAM, and modem are checked.If initialization fails for the ICs , the system will not boot up.In this case, please find the cause as follows.CROSS REFERENCE:NG EXAMPLE (P.83)CHECK THE STATUS OF THE DIGITAL BOARD (P.84)POWER SUPPLY BOARD SECTION (P.99)KX-FL503TKCROSS REFERENCE:LCD MESSAGE (P.4)CHECK THE STATUS OF THE DIGITAL BOARD (P.84)KX-FL503TK 2.3.8.2.NG EXAMPLEKX-FL503TK2.3.8.3.CHECK THE STATUS OF THE DIGITAL BOARDKX-FL503TK2.3.9.ANALOG BOARD SECTIONThis chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on each route is shown in the Check Sheet here.

　电阻焊方法主要有四种，即点焊、缝焊、凸焊、对焊。

　点焊时，工件只在有限的接触面上，即所谓“点”上被焊接起来，并形成扁球形的熔核。

点焊又可分为单点焊和多点焊。

多点焊时，使用两对以上的电极，在同一工序内形成多个熔核。
