123.2.4. Troubleshooting by Symptom (Base Unit and Charger Unit)3.2.4.1. Check Point (Base Unit)[Changed from original section "9.2.1. Check Point (Base Unit)"]Please follow the items below when BBIC or EEPROM is replaced.Note:After the measuring, suck up the solder of TP.*: PC Setting is required beforehand.The connections of simulator equipment are as shown in Adjustment Standard (Base Unit) (P.18).Items AdjustmentPointProcedure Check orReplace Parts(A) 2.65V SupplyConfirmation- 1. Confirm that the voltage between VDD and GND is 2.65V ± 0.2V. C58, C40, F1,C34, IC2, R35,R36, C28,C11, C48, R17(B) VDDIO Confirmation - 1. Confirm that the voltage between C24 and GND is 2.5 ± 0.3. IC3, X1, C22C23, C17(C)* BBIC Confirmation - 1. BBIC Confirmation (Execute the command “getchk”).2. Confirm the returned checksum value.Connection of checksum value and program number is shown below.IC3, X1, C22C23, C17(D)* BBIC Clock Adjustment(Important)P1.0CLK1. Execute the command “EnableClockOutput”.2. Input Command “GetFreq”, then you can confirm the current value.3. Check X’tal Frequency. (10.368 MHz ± 100 Hz).4. If the frequency is not 10.368MHz ± 100Hz, adjust the frequency of CLKexecuting the command “setfreq 04 xx (where xx is the value)” so that thereading of the frequency counter is 10.368000 MHz ± 5 Hz.IC3, X1, C22C23, C17(E)* Hookswitch Check withDC Characteristics- 1. Connect J1 (Telephone Socket) to Tel-simulator which is connected with 600.2. Set line voltage to 48V at on-hook condition and line current to 40mA at off-hook condition of normal telephone.3. Execute the command “hookoff”.4. Confirm that the line current is 40mA ± 5mA.5. Execute the command “hookon”.6. Confirm that the line current is 0mA + 2mA.IC3, C30, C31,D2, Q3, R26,R22, Q2, C45,C21, R18,R15, P101,SA1(F)* DTMF Generator Check - 1. Connect J1 (Telephone Socket) to DTMF tester.2. Execute the command “hookoff” and “dtmf_up”.3. Confirm that the high frequency (1477.06Hz) group is -6.0 ± 2dBm.4. Execute the command “dtmf_low”.5. Confirm that the low frequency (852.05Hz) group is -8.0 ± 2dBm.IC3, R2, C4,C5, R7, R9,R10, C9, Q1,R6, R12, D1,Q3, R26, R22,Q2, C45, C21,R18, R15, D2,C30, C31,P101,SA1(G)* Transmitted PowerConfirmation- Remove the Antenna before starting steps from 1 to 5.1. Configure the DECT tester (CMD60) as follows;• Test mode: FP• Traffic Channel: 5• Traffic Slot: 4• Mode: Loopback• PMID: 000002. Execute the command “testmode”.3. Initiate connection from DECT tester. (“set up connect”)4. Execute the command “ANT2”.5. Confirm that the NTP value at ANT is 19dBm~25dBm.IC3, C813,P101, SA1,C811, C812C807, C819,C826, D801,C808, C810,D6, C809,C39, C38,RA43, C823,C821, RA801,C803, C825,C44, C806,C802, C804,C820, C830,C815, L1checksum valueex.) program numberDCM1EB0152
