<Setting>
-Test mode: FP
-Mode: Normal
-PMID: 0000
2. Execute the command "testmode".
3. Initiate connection from DECT tester.
4. Execute the command "hookoff".
5. Execute the command "openau".
6. Connect J2 (Telephone Socket) to Tel-simulator which is connected with 600
.
7. Set line voltage to 48V and line current to 40mA.
8. Connect DECT tester to Tel-simulator.
9. Input audio signal (200mVrms/1kHz tone) to Tel-simulator.
<DECT tester setting>
-Scramble: On
-AF Gen to ADPCM: Off
-AF Meter Input: ADPCM
-AF Gen Frequency: 1000Hz
-AF Gen Level: 200mVrms
10. Confirm hearing tone: 300mVrms ± 100mVrms
11. Adjust audio level if required. (Make sure current value using "getmicgain". And then
execute the command "setmicgain xx", where xx is the value.)
12. Confirm that the B-field audio distortion with DECT tester is < 5 %.
