Remedies depend on whether you have DECT tester(*1) or not.Note:(*1) A general repair is possible even if you don’t have the DECT tester because it is for confirming the levels, such as Acousticlevel in detail.(*2) Refer to Check Point (Base Unit) (P.35)9.2.1. Check Point (Base Unit)Please follow the items below when BBIC or EEPROM or FLASH is replaced.Note:After the measuring, suck up the solder of TP.*: The Setting Method of JIG (Base Unit) (P.47) is required beforehand.The connections of simulator equipment are as shown in Adjustment Standard (Base Unit) (P.49).You have DECT Tester.(Model Number : CMD60)Check item (A)-(I),(T). Check item (A)-(I), (J)-(P),(T).Check item (A)-(G),(Q),(T). Check item (A)-(G), (J)-(P), (Q),(T).- Check item (J)-(P).Check item (Q). Check item (Q).Check item (Q). Check item (Q).Check item (A)-(I). Check item (A)-(P).You cannot dial.You cannot hear the caller's voice.You cannot use handset a little away from base uniteven if the handset is within range of the base unit.The acoustic transmit level is high or low.The acoustic reception level is high or low.Base unit and handset do not link each other.The unit cannot charge. Check item (R). Check item (R).Remedy (*2)Symptom You don't have DECT Tester.Items CheckPointProcedure Check orReplace Parts(A) 3.0 V SupplyConfirmationVDD3 1. Confirm that the voltage between test point VDD3 and GND is 2.85 V ± 0.2 V. IC2, C32, C36,C86, C88, R91,R93, L3, C602,C38, R605,R607, R608,R609, R610,R612, Q602(B) 1.8 V SupplyConfirmationVDD1 1. Confirm that the voltage between test point VDD1 and GND is 1.8 V ± 0.02 V.2. Execute the command “VDD”, then check the current value.3. Adjust the 1.8V voltage of VDD1 executing command “VDD XX“(XX is thevalue).Q8, C75, C614,C61, IC7, R611(C) Charge Pump 3.0VSupply ConfirmationVDD5 1. Confirm that the voltage between test point VDD5 and GND is 3.0 V -0.1/+0.3V.IC7,C625(D) Charge Pump 3.0VSupply ConfirmationVDD4 1. Confirm that the voltage between test point VDD4 and GND is 3.0 V ± 0.2 V. IC7,C616, R620(E)* 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.IC7, X1, R77,RA80(F)* EEPROM Confirmation - 1. EEP-ROM Confirmation (Execute the command "sendchar EPV").2. Confirm the returned Value (Value for reference is written at "EEPROM C/SUM" in Software_Version_Table.xls).IC7, RA402,C51, R657,IC401(G)* BBIC Clock Adjustment CLK 1. Confirm that the voltage between testpoint VDD4 and GND is less than 1.0 V.2. Input Command “ sendchar sfr”, then you can confirm the current value.3. Check X’tal Frequency. (10.368 MHz ± 20 Hz).4. If the frequency is not 10.368MHz ± 20 Hz, adjust the frequency of CLKexecuting the command “sendchar sfr xx xx (where xx is the value)” so thatthe reading of the frequency counter is 10.368000 MHz ± 5 Hz.X1, IC7, R430,C305checksum valueB10Cprogram numberDCE1ENex.)
