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.24)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 (P.34) is required beforehand.The connections of simulator equipment are as shown in Adjustment Standard (Base Unit) (P.36).Items AdjustmentPointProcedure Check orReplace Parts(A) 2.65V SupplyConfirmation- 1. Confirm that the voltage between VDD and GND is 2.65V ± 0.2V. C58, C60, F1C35, C34, IC2C29, R35, R36C28, C103,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 xx 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 600Ω.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, R15You have DECT Tester.(Model Number : CMD60)Check item (A)-(E).
