| and when receiving | supplied in the box with your HP Fax.* This special 2-wire cord is |

*This possible cause/solution applies only in the countries/regions that receive a 2-wire phone cord in the box with the HP Fax, including: Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Greece, India, Indonesia, Ireland, Japan, Korea, Latin America, Malaysia, Mexico, Philippines, Poland, Portugal, Russia, Saudi Arabia, Singapore, Spain, Taiwan, Thailand, USA, Venezuela, and Vietnam.
If you used a 4-wire cord, disconnect it, find the supplied 2-wire cord, and then connect the 2-wire cord to the HP Fax (at the port labeled “1-LINE”). For more information on how to connect this cord, see fax setup on page 75.
Note: If the 2-wire cord is not long enough and you need to extend it, you might want to purchase an in-line coupler and use a 4-wire cord to increase the length. The type of coupler you would need allows you to connect a 2-wire cord at one end, and a 4-wire cord at the other. Attach the 2-wire cord from the “1-LINE” port of the HP Fax to one side of the coupler; then attach a 4-wire cord from the opposite side of the coupler to the telephone wall jack.
