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.
(*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.

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.
*: The Setting Method of JIG (Base Unit) (P.33) is required beforehand.
The connections of simulator equipment are as shown in Adjustment Standard (Base Unit) (P.35).

1. Execute the command “EnableClockOutput”.
2. Input Command “rdeeprom 00 00 02”, 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 CLK
