 Connect the telephone line cords:
If you have two dual line wall jacks installed in your home or office, plug one end of the straight telephone line cord tagged as “LINE 1+2†into the jack marked LINE 1 + 2 and one end of the other straight line cord into the other jack on the back of the base.
Plug the other end of each line cord into the dual-line wall jacks.
If you have four single-line wall jacks installed in your home or office, you must use adaptors/couplers (not included) to combine the four single telephone lines into two dual lines. The adaptor/coupler may look similar to the one pictured here and can be purchased from your local telephone products retailer.
NOTE: To use four lines, you must have four telephone lines with unique telephone numbers.
If you only have one telephone line, this phone will still operate, but only as a single line telephone.
Unit Initialization:
After you connect the power supply and Line 1 to the unit, the system automatically searches for and sets up a phone ID.
