Enable or disable error correction mode (ECM). ECM checks for fax data errors and corrects them. To reduce

errors on received faxes, see

ECM must be enabled on both the machine and the other fax device because error checks are

performed on both the sending and receiving devices.

Even when ECM is enabled, errors may occur due to telephone line conditions.

It may take a longer time than usual to process data when ECM is enabled because the error checks

and corrections are performed while the data is transmitted.

For example, when you make calls by dialing "0 - (pause) - (telephone number)," 0 is dialed first and then a few

seconds later, the telephone number. When sending faxes overseas, you need to specify destinations by dialing

"(international access code) - (country code) - (area code) - (fax number)" but consecutive numbers that are

input without pauses may not be recognized correctly. In this case, try adding a pause after the international

access code or the fax number. If the code or the number is still not recognized correctly, change the duration

of the pause. For instructions on how to enter a pause, see

to 15 (sec.)

Specify settings for Auto Redial, a function that automatically redials the fax number after several minutes if the

first attempt fails because the line is busy. You can specify how many times the machine redials and the interval

between redials.
