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.40)
9.3.1.
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.53) is required beforehand.
The connections of adjustment equipments are as shown in
Adjustment Standard (Handset)
(P.55).

(
A
)* 1.8 V Supply Adjustment
1.8V
1. Confirm that the voltage between test point VDD1 and GND is 1.8 V ± 0.02 V.
2. Execute the command “VDD”, then check the current value.
3. Adjust the 1.8V voltage of 1.8V executing command “VDD XX“(XX is the
value).

(
C
)* EEP-ROM Confirmation
CP2.5V
1. EEP-ROM Confirmation (Execute the command “ChkTGA800XXrevYY.bat”).
XX: country code
YY: revision number
2. Confirm the returned checksum value.
Note:
“XX”, “YY”, and “checksum” vary depending on the country version. You can find
them in the batch file, PQZZ- mentioned in
The Setting Method of JIG (Hand-
set)
(P.53).

(D) 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.)
