9 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.
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 (Handset) (P.31)
9.1. Check Point (Handset)
Please follow the items below when BBIC or EEPROM is replaced.
Note:
After the measuring, sock up the solder of TP.
*: PC Setting (P.34) is required beforehand.
The connections of simulator equipments are as shown in Adjustment Standard (Handset) (P.35).
