Troubleshooting by Symptom (Base Unit and Charger Unit)

If your unit has below symptoms, follow the instructions in remedy column. Remedies depend on wether 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.51)
9.2.1. Check Point (Base Unit)
Please follow the items below when BBIC, EEPROM or FLASH is replaced.
Note:
After the measuring, suck up the solder of TP.
*: How to install Batch file into P.C. (P.66) is required beforehand.
The connections of simulator equipments are as shown in Adjustment Standard (Base Unit) (P.67).
Items
(A) 3.5 V Supply Confirma-
tion
(B) 3.75 V Supply Confirma-
tion
(C) 2.5 V Supply Confirma-
tion
(D) 3.0 V Supply Confirma-
tion
(E) 1.8 V Supply Confirma-
tion
(F)* BBIC Confirmation
(G)* EEPROM Confirmation
(H)* BBIC Clock Adjustment
Check
Point
VDD3 1. Confirm that the voltage between test point VDD3 and GND is 3.5 V ± 0.2 V.
VDD5 1. Confirm that the voltage between test point VDD5 and GND is 3.75 V ± 0.2 V.
VDD2 1. Confirm that the voltage between test point VDD2 and GND is 2.5 V ± 0.2 V.
VDD4 1. Confirm that the voltage between test point VDD4 and GND is 3 V ± 0.2 V.
VDD1 1. Confirm that the voltage between test point VDD1 and GND is 1.8 V ± 0.1 V.
- 1. BBIC Confirmation (Execute the command "getchk").
2. Confirm the returned checksum value.
Connection of checksum value and program number is shown below.
- 1. EEPROM 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)
Note:
"checksum" vary depending on the country version. You can find them in the
batch file, PNZZ- mentioned in The Setting Method of JIG (Base Unit) (P.65).
CLK 1. Check X'tal Frequency. (10.368 MHz ± 100 Hz).
GND_C Input Command "sendchar sfr", then you can confirm the current value.
2. If the frequency is not 10.368 MHz ± 100 Hz, Adjust the frequency of CLK exe-
cuting the command "sendchar sfr XX YY (where XX YY is the value)" so that
the reading of the frequency counter is 10.368000 MHz ± 20 Hz.
