Page 193 2WA/2NJ/2RK-2 2-5 Initializing procedures after installing the FAX system 1. Connect the power plug of the main unit to the outlet and turn the power on. 2. Input "10871087" using the numeric keys to enter the maintenance mode. 3. Input "600" using the numeric keys and press the [Start] key. 4.
Page 194 2NJ/2RK IMPORTANT Note the following points when installing the FAX system in the line via ISDN or PBX. Check if the line to connect supports the V.34 (Super G3) FAX communication. Especially, when communicating between extensions in PBX (private line via TDM), only 14400bps or 9600bps of FAX communication speed is guaranteed and communication errors or TX/RX image failure may occur at V.34 com- munication in such a line.
