Audio Check
-
1. Link with Handset.
2. Input -45dBm/1kHz to MIC of Handset.
Measure the Level at Line I/F and distortion level.
3. Confirm that the level is -8.5 dBm ± 2 dBm and that the distortion level is < 5%
at TEL Line (600
Ω
Load).
4. Input -20 dBm/1 kHz to Line I/F.
Measure the level at Receiver of Handset and distortion level
(*Receive volume set to second position from minimum).
5. Confirm that the level is -21 dBm ± 2 dBm and that the distortion level is < 5%
at Receiver (Volume Middle, 150
Ω
Load).
