1. Configure the DECT tester (CMD60) as follows;
<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 J1 (Telephone Socket) to Tel-simulator which is connected with 600
Ω.
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: 390mVrms ± 85mVrms
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 %.
