Items Adjustment Point Procedure Check orReplace Parts(R) Audio Check (CurlCord Handset)- 1. Input -45dBm/1kHz to MIC of Curl Cord Handset.Measure the Level at Line I/F and distortion level.2. Confirm that the level is -15dBm ± 5dB and confirm that the distortion levelis < 5%. (600Ω Road)3. Input -20dBm/1kHz to Line I/F.Measure the level at Receiver of Carl Cord Handset and distortion level(*Receive volume set to middle).4. Confirm that the level is -24dBm ± 5dB and confirm that the distortion levelis < 5%.
