Dedicated Transmission Parameters
4.8 DEDICATED TRANSMISSION PARAMETERS
There are two sets of transmission parameters: Fax and E-mail
Each Quick Dial Key and Speed Dial Code has eight bytes of programmable parameters allocated
to it. If transmissions to a particular machine often experience problems, store that terminal's fax
number as a Quick Dial or Speed Dial, and adjust the parameters allocated to that number.
The programming procedure will be explained first. Then, the eight bytes will be described.

second.
Range:
0 to 120 s (00h to 78h)
FFh - The local NCU parameter factory setting is used.
