Protect your modem from dangerous over-current with the Modem Defender. The high current of digital telephone lines (found in most hotels) can seriously damage your modem. Why take chances? This checks the status of the phone line before you connect, and instantly lets you know the condition of the line. It also reverses polarity for optimum connection, has embedded surge protection, and doubles as an RJ-11 coupler. Perfect condition. Includes item, case, jacks, line and pouch. FREE SHIPPING TO CONTINENTAL USA
