C) How to change the Auto Disconnect activation (time)
Some Telephone Company lines (fiber or cable) ON Hook and OFF Hook voltages are lower than conventional lines, which may
cause a malfunction of Auto Disconnect detection. To solve this problem, try changing the Auto Disconnect activation through
the procedures below.
Auto Disconnect detect
Enable*1
Enable*1 [default]
Disable*2
Note:
*1 Both Auto Disconnect and CPC don't detect for the first 2 seconds.
*2 If the "Disable" is selected, even if the parallel-connected telephone is OFF HOOK, the line isn't disconnected.
D) How to change the VOX level
It makes easier to detect a small voice (caller) by raising the sensitivity of VOX level. Therefore, the recording of TAM is not
turned off during a detection.
VOX Level sensitivity
Normal [default]
10 dB Up
