INTERFERENCE INFORMATION: PART 15 OF FCC RULES Some telephone equipment generates and uses radio frequency energy which if not properly installed, may cause interference to radio and television reception. This unit has been tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, when it’s in use, the user is encouraged to try to correct the interference by one or more of the following measures: A. Where it can be done safely, reorient the radio or TV receiving antenna. B. To the extent possible, relocate the television, radio, or other receiver with respect to the telephone equipment. C. If your telephone product runs on AC power, plug your product into an AC outlet that’s not on the same circuit as the one used by the radio or television. 4 FCCREGULATIONS CONTINUED Warning:Modifying or tampering with the telephone's internal components can cause a malfunction and might invalidate the telephone's warranty and void your FCC authorization to operate it. If the trouble is harming the telephone lines, the telephone company might ask you to disconnect the telephone until you have resolved the problem. As it complies with Part 68 of the FCC rules and the technical requirements for connection to telephone networks published by ACTA, your unit has been registered with the FCC. The FCC requires us to provide you with the following information: 1.
