Do not use a three-to-two pronged adapter at the outlet. Doing so may result in electrical shock and/or damage to the repeater.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-3 ■ The wiring must be shielded or unshielded twisted-pair (STP/UTP), Category 5. ■ Two pairs of wiring are required. ■ Depending on building codes, different insulation materials may be required. Plenum-rated or TEFLON-coated wiring may be required in some areas. ■ The wire gauge should be between 18 and 26 AWG. (Most telephone installations use 24-gauge wiring.
