1. If normal communications are possible between A and C, and the communication trouble occurs B
and C, it can be assumed that FAX B is malfunctioning.
2. If normal communications are possible between B and C, and the communication trouble occurs A
and C, it can be assumed that FAX A is malfunctioning.
Therefore, adjust the transmission attenuator value (FS-13-325, FS-13-430).
3. If normal communications are possible between A and C and between B and C, it can be assumed
that there is a problem in the line between A and B.
7.5.6 Noise is heard when monitor dialing transmission
When monitor dialing transmission by using an external telephone is attempted, a noise sometimes is
heard from the speaker. If this has occurred due to the condition of the line, the noise will be able to be
prevented by changing the address of the line and the setting of the data.
Notes:
Confirm that the version of the fax firmware is the latest one.
1. Enter into the FS-FAX-19 RAM EDIT MODE.
2. Select the line of which the noise has occurred.
3. Press [Address]. Enter “5600” and press [OK].
4. Press [Data]. Enter “0AF1” and press [OK].
5. Press [Set].
6. Press [Write].
7. Press [OK] on the confirmation pop-up screen.
8. Restart the MFP and confirm that the noise cannot be heard.
If the noise is still heard, change the value to “0A71” to be entered into [Data].
Notes:
• If a problem, such as the disabling of the communication, has occurred due to the entry of a
different value from that for this procedure into [Address] or [Data], correct the setting value
by reattempting this.
• If the noise cannot be stopped by means of this procedure, replace the fax board of the line
from which the noise has occurred.
