If you are having problems sending or receiving a fax due to possible interference on the phone line, we recommend that you adjust the Equalization for compatibility to reduce the modem speed for fax operations.

| 2 | Press  or  to choose Fax. Press OK. |
| 3 | Press  or  to choose Miscellaneous. Press OK. |
| 4 | Press  or  to choose Compatibility. Press OK. |
| 5 | Press  or  to choose Normal. | • | Basic reduces the modem speed to 9600 bps. Unless interference is a recurring problem on your phone line, you may prefer to use it only when needed. | | • | Normal sets the modem speed at 14400 bps. (factory setting) |
Press OK. |
| 6 | Press Stop/Exit. |
