12.5.13. Troubleshooting by Symptom (Cordless 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 (Cordless Handset)

) Charge Control Check &
Charge Current Monitor
Check
-
1. Apply 3.5 V between CHG(+) and CHG(-) with DC power supply and set cur-
rent limit to 250 mA.
Confirm the indication of “charging” on LCD.
2. Confirm that the current limit LED of DC power supply is ON/OFF.
Confirm it after waiting over 1 minute at least.
3. Decrease current limit of DC power supply to 100 mA.
4. Confirm that the current limit LED of DC power supply is stable. (Current limiter
is ON.)
(If charge control cannot be confirmed by this procedure, please use battery to hand-
set power supply and try again.)
