( F ) Charge Control Check &
Charge Current Monitor
Check
- 1. Apply 6V between J3(+) and J4(-) with DC power supply and set current limit to
250mA.
2. Confirm that the current limit LED of DC power supply is ON/OFF.
3. Decrease current limit of DC power supply to 100mA.
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
handset power supply and try again.)

( G )* Charge Detection (OFF)
Check
- 1. Stop supplying 6V to ) and CHARGE(-).
2. Execute the command “Backloff” then “charge”.
3. Confirm that the returned value is 0x00 (hex).

( H )* Battery Monitor Check - 1. Apply 2.25V between BATT and GND.
2. Execute the command “readbatt”.
It assumes that the return value is XX.
a) 1E XX 2C: No need to adjust
b) XX: 18 ~ 1D: Need to adjust
XX: 2D ~ 32: Need to adjust
Write AD value of 2.25V to EEPROM.
ex) read data: XX = 1D, write data: YY = 1D
read data: XX = 2D, write data: YY = 2D
EEPROM = 0X0004(LowVoltage) write “YY”, then
EEPROM = 0X0005(No Voltage) write “YY - 1D”
EEPROM = 0X000A(LowVoltage BL) write “YY - 06”
No Voltage writing data limit is ‘00’.
c) XX: 00 ~ 17: Reject
XX: 33 ~ FF: Reject

( I ) Battery Low
Confirmation
- 1. Apply 2.40V between B) and BATTERY(-).
2. Confirm that there is no flashing of Battery Icon.
3. Apply 2.25V ± 0.08V between B) and BATTERY(-).
4. Confirm that there is flashing of Battery Icon.

( J )* BBIC Clock Adjustment CLK 1. Apply 2.6V between B) and BATTERY(-) with DC power.
2. Execute the command “conttx”.
3. Input Command “rdeeprom 00 01 01”, then you can confirm the current value.
4. Adjust the frequency of CLK executing the command “setfreq xx (where xx is
the value)” so that the reading of the frequency counter is 10.368000MHz ±
10Hz.
Note:
CLK is displayed only for a fewseconds when executing the command “conttx”
after battery is inserted.

( K )* Transmitted Power
Confirmation
- Remove the Antenna before starting step from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
·
Test mode: PP
· RFPI: 0102030405
·
Traffic Carrier: 5
·
Traffic Slot: 4
· Mode: Loopback
· RF LEVEL = -70dBm
2. Execute the command "regcmd60 01 02 03 04 05".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at A201 is 20dBm ~ 25dBm.
