V34 is a communication mode used for the Super G3 fax communication.
This can shorten the communication time and reduce communication costs because a single page of letter/A4 size paper can be sent in as little as approximately three seconds.
By default, this machine transmits faxes with V34. You can send faxes with V34 canceled if it is not possible to establish a communication in the Super G3 mode depending on telephone line conditions (for example, when the remote or this machine is connected to a PBX line).
Transmission begins.
