14 TROUBLESHOOTING BY SYMPTOM (BASE UNIT AND
CHARGER UNIT)
If your unit has below symptoms, follow the instructions in remedy column. 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 Acoustic
level in detail.
(*2): Refer to Check Point (Base Unit) (P.48)
14.1. Check Point (Base Unit)
Please follow the items below when BBIC or EEPROM or FLASH ROM is replaced.
Note:
After the measuring, sock up the solder of TP.
*: PC Setting (P.59) is required beforehand.
The connections of adjustment equipments are as shown in Adjustment Standard (Base Unit) (P.53).

Point
Procedure
Check or
Replace Parts
(A)
3.3V Supply
Confirmation
TP14
1.
Confirm that the voltage between test point VDD3 and GND is 3.3V ± 0.2V.
D1, IC1, C1,
C119, C2, R8,
R9, C114, C34,
C8, R85
(B)
2.5V Supply
Confirmation
TP22
1.
Confirm that the voltage between test point VDD2 and GND is 2.5V ± 0.2V.
Q2, C5, C7,
C168
(C)*
1.8V Supply
Confirmation
TP15
1.
Confirm that the voltage between test point VDD1 and GND is 1.8V ± 0.1V.
Q3, C6, C11,
C48, C4, C37,
C39, C44, C45
(D)*
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.
IC8, X1, C42,
C43, R40, C6,
C11, C48, C4,
C37, C39, C44,
C45, R124,
R125, C153
(E)* EEP-ROM Confirmation
-
1.
EEP-ROM Confirmation (Execute the command "ChkTCD220XXrevYY").
XX: country code
YY: revision number
2.
Confirm the returned checksum value.
Note:
“XX”, “YY”, and “checksum” vary depending on the country version. You can
find them in the batch file, PQZZ- mentioned in JIG and PC (P.52).
IC3, C53, R56,
R57
(F)* BBIC Clock Adjustment
CLK
1.
Input Command “rdeeprom 00 01 01”, then you can confirm the current value.
2.
Adjust the frequency of CLK executing the command "setfreq xx (where xx is
the value)" so that the reading of the frequency counter is 10.368000MHz ±
10Hz.
