Point
TP15 1. Configure the DECT tester (CMD60) as follows;
<Setting>
• • • • Test mode: PP
• • • • Mode: Normal
• • • • RFPI: 0102030405
2. Execute the command "testmode".
3. Execute the command "regcmd60".
4. Initiate connection from DECT tester.
5. Execute the command "openaudio".
6. Confirm that the value of EEPROM address "F3F" is "02". (If the value is not
"02 (by User)", set "02" and power off and power on, and return to clause 2.)
7. Input audio signal (50mVrms/1kHz tone) from DECT tester.
<DECT tester setting>
• • • • Scramble: On
• • • • AF Gen. to ADPCM: On
• • • • AF Meter Input: AF Voltm
• • • • AF Gen. Frequency: 1000Hz
• • • • AF Gen. Level: 50mVrms
8. Confirm hearing tone: 70mVrms ± 30mVrms (Just check Audio path)
9. Confirm that the audio distortion with DECT tester is < 5%.
TP15 1. Configure the DECT tester (CMD60) as follows;
<Setting>
• • • • Test mode: FP
• • • • Mode: Normal
• • • • RFPI: 0102030405
2. Execute the command "testmode".
3. Execute the command "regcmd60".
4. Initiate connection from DECT tester.
5. Execute the command "openaudio".
6. Confirm that the value of EEPROM address "F3F" is "02". (If the value is not
"02 (by User)", set "02" and power off and power on, and return to clause 2.)
7. Input audio signal (30mVrms/1kHz tone) to DECT tester.
<DECT tester setting>
• • • • Scramble: On
• • • • AF Gen. to ADPCM: Off
• • • • AF Meter Input: ADPCM
• • • • AF Gen. Frequency: 1000Hz
• • • • AF Gen. Level: 30mVrms
8. Confirm hearing tone: 530mVrms ± 100mVrms (Just check Audio path)
9. Confirm that the audio distortion with DECT tester is < 5%.
- 1. Link to BASE which is connected to Line Simulator.
2. Set line voltage to 48V and line current to 40mA.
3. Input -45dBm/1KHz to MIC and measure Line output level.
4. Confirm that the level is -7.5 ± 2dBm and that the distortion level is < 5% at
TEL Line (600Ω Load).
5. Input -20dBm/1KHz to Line I/F and measure Receiving level at SP+ and SP-.
6. Confirm that the level is -23 ± 2dBm and that the distortion level is < 5% at
Receiver. (vol = Low, 150Ω Load)
