Are you using a phone line splitter?
A phone line splitter is a device used to split out two or more phone line jacks to connect phones or
devices to the same phone line wall jack. Confusion can result from the existence of two different
kinds of splitters.
Parallel splitters (also called “T” splitters) split a single line into two jacks, allowing two devices to
be plugged into the same line.
Line1/Line2 splitters provide two phone line outlets from a single jack with two unique phone
numbers (two phone lines are connected to a single wall jack). A Line1/Line2 splitter must be used
if you have a fax line and a voice line coming into the same wall jack.
See “Connecting the product to a phone line” in the fax guide that came with your product for
instructions.
Note
Parallel or “T” splitters should not be used with the product, as they can degrade the quality of the
phone signal. If you need to attach a second device to the phone line along with the product, plug
the second device into the product’s “phone” socket (the socket on the bottom) inside the product’s
left side panel. See “Connecting the product to a phone line” in the fax guide that came with your
product for instructions.
