Notes on the Telephone Line
❑The internal fax modem can be connected to the subscriber telephone line. Do not connect it to the PBX (Private Branch Exchange). Connecting to the PBX may cause a failure or fire.
❑Some PBXs may use the same electric requirements as the subscriber telephone line of the local telephone company. Ask the manufacturer of your PBX or your PBX maintenance agent for compatibility.
❑The internal modem of your computer is set to hang up if the called party does not answer within 60 seconds. You may change this length to less than 30 seconds, which, however, may prevent a connection from being established due to some delays caused by the telephone switch. It is advised to set the length to 30 seconds or more.
❑If your Internet service provider supports V.90 or 56K, communications of up to 56 Kbps are available. This, however, may vary depending on the telephone line condition.
❑If you use a splitter to branch the telephone line, the internal fax modem may not operate successfully.
❑Select the appropriate mode adopted in your country. You can select it from the Modem Properties dialog box.
