J1
1.
Configure the DECT tester (CMD60) as follows;
<Setting>
•
Test mode: FP
•
Mode: Low
•
PMID: 00000
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.
Input audio signal (30mVrms/1kHz tone) to DECT tester.
<DECT tester setting>
•
Scramble: On
•
AF Gen. to ADPCM: On
•
AF Meter Input: AF Voltm
•
AF Gen. Frequency: 1000Hz
•
AF Gen. Level: 30mVrms
9.
Confirm hearing tone: 380mVrms ± 100mVrms.
10. Adjust audio level if required. (Make sure current value using “getspkrgain”.
And then execute the command “setspkrgain xx”, where xx is the value.)
11. Confirm that the audio distortion at 600R of Tel-simulator is < 5%.

Charging Check
-
1.
Connect Charge Contact 12
Ω
/2W resistor between charge+ and charge-.
2.
Measure and confirm voltage across the resistor is 2.3V ± 0.2V.

Audio Check
-
1.
Link with Handset.
2.
Set line voltage to 48V and line current to 40mA.
3.
Input -45dBm/1kHz to MIC of Handset.
Measure the Level at Line I/F and distortion level.
4.
Confirm that the level is -7.5 ± 2dBm and that the distortion level is < 5% at
TEL Line (600
TEL Line (600
Ω
Load).
5.
Input -20dBm/1kHz to Line I/F.
Measure the level at Receiver of Handset and distortion level
(*Receive volume set to second position from minimum).
6.
Confirm that the level is -23 ± 2dBm and that the distortion level is < 5% at
Receiver (vol = Low, 150
Receiver (vol = Low, 150
Ω
Load).
