Set the fax error correction mode
Typically, the device monitors the signals on the phone line while it is sending or
receiving a fax. If it detects an error signal during the transmission and the error-
correction setting is on, the device can request that a portion of the fax be resent.
Turn off error correction only if you are having trouble sending or receiving a fax, and
you want to accept the errors in the transmission. Turning off the setting might be
useful when you are trying to send a fax to another country/region or receive a fax
from another country/region, or if you are using a satellite phone connection.
