NOTE: Selectors 1 through 3 and 6 through 8 are applicable to those models equipped with a built-in TAD.

NOTE: Selector 6 is not applicable to the U.S.A. versions.

•Selectors 1 through 3: Detection threshold level for voice signals inputted via the telephone line in the built-in TAD operation

If the equipment detects voice signals exceeding the threshold level set by these selectors, it will interpret them as effective voice.

•Selectors 4 and 5: FAX receiving speed to be kept within the transmission speed limit to the PC

To transmit FAX data being received from other facsimile equipment to the connected PC, you may need to keep the FAX receiving speed within the transmission speed limit to the PC. In an initial negotiation sequence for transmission, the equipment responds to the calling station with the allowable FAX receiving speed specified by these selectors.

•Selectors 7 and 8: Comfortable noise level

These selectors set the level of noise to be added during playing-back of voice signals recorded with no-signal compression.

If they are set to "0, 0," no noise will be added.
