Troubleshooting by Symptom (Handset)
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 (Handset)
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 (Handset) (P.37) is required beforehand.
The connections of simulator equipment are as shown in Adjustment Standard (Handset) (P.39).
