Setting ECM OFF
Transmission can be made with ECM disabled. Error correction mode (ECM)
is a mode of transmission with error correction established by ITU-T (Inter-
national Telecommunications Union). Fax machines equipped with the ECM
feature can communicate with each other and can confirm that the data sent
is free of errors. Thus, communication can be made free from disturbances
due to line noises, etc. The FK-502 employs ECM for transmission unless
you disable it.

Specifications
If there are many line disturbances, the communication time may be a lit-
tle bit longer with ECM enabled than with ECM disabled.
