)* Audio Check
-
1. Link with Handset which is connected to Line Simulator.
2. Set line voltage to 48V and line current to 50mA.
3. Input -45dBm(600
Ω
)/1kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -6.0 ± 3dBm and that the distortion level is < 5% at TEL
Line (600
Ω
Load).
5. Input -20dBm(600
Ω
)/1kHz to Line I/F. Measure the level at Receiver of
Handset and distortion level (*Receive volume set to third position from
minimum).
6. Confirm that the level is -21.0 ± 3dBm and that the distortion level is < 5% at
Receiver (150
Ω
Load).
