Adjust
The closer the sensitivity setting is to –16 dB, the
less likely it will be that the unit will detect low level
noise on the line. This increases the possibility for
the unit to switch using the silent detection when in
the Ans/Fax Ready mode. The closer the setting is
to –43 dB, the more likely it is to detect noise.
This will
decrease the possibility of switching due to silent
detection.

Adjust
If retraining occurs due to the low reception signal
level and delay in the telephone line, it may overlap
the second post-message. In this case, increase
the delay before the post-message is transmitted.
