13 TROUBLESHOOTING BY SYMPTOM (BASE UNIT AND
CHARGER UNIT)
Ifyour unit has below symptoms, follow the instructions in remedy column. Remedies depend on whether you have DECT tester
(*1) or not.

(*2): Refer to Check Point (Base Unit) (P.47)
13.1. Check Point (Base Unit)
Please follow the items below when BBIC or EEPROM is replaced.
Note:
After the measuring, sock up the solder of TP.
*: PC Setting (P.58) is required beforehand.
The connections ofadjustment equipments are as shown in Adjustment Standard (Base Unit) (P.52).
