Sony PCG-SR33K - Manual (Page 88)

Notes on using the phone line
 The internal fax modem can be connected to the subscriber phone line. However, do not connect it to the
Private Branch Exchange (PBX). Connecting it to the PBX may cause a failure or fire.
 Some PBXs may use the same electric requirements as the subscriber phone line of the local phone company.
Ask the manufacturer or your PBX maintenance agent about PBX compatibility.
 The notebook's internal modem is set to hang up if the called party does not answer within 60 seconds. You
may set the time to 30 seconds or less, but the shorter length may prevent you from establishing a
connection due to delays caused by phones switching. It is recommended that you set the length to 30
seconds or longer.
 If your Internet Service Provider (ISP) supports a V.90/K56flex compatible modem, communications of up to
53 Kbps are available. This may vary, depending on the condition of the phone line.
 If you use a splitter to branch the phone line, the internal fax modem may not operate successfully.
 Make sure you select the mode adopted in your country from the Modem Properties dialog box.
