Operating Instructions

Problem Cause & Solution
I cannot hear a dial
tone.
• The telephone line cord is connected to the [EXT] jack on the unit. Connect to
the [LINE] jack (page 28).
• If you use a splitter/coupler to connect the unit, remove the splitter/coupler and
connect the unit to the wall jack directly. If the unit operates properly, check the
splitter/coupler.
• Disconnect the unit from the telephone line and connect a known working
telephone. If the working telephone operates properly, contact our service
personnel to have the unit repaired. If the working telephone does not operate
properly, contact your telephone company.
• The power cord or telephone line cord is not connected. Check the
connections (page 28).
• If you connected the unit through a computer modem, connect the unit directly
to a telephone line jack.
