Do not install electrical equipment in wet or damp conditions. Ensure that the power source for the system is adequately rated to assure safe operation and provides current overload protection. Do not allow anything to rest on the power cable, and do not place this product where people will stand or walk on the power cable. To avoid electric shock of user which caused by over-voltage from PSTN. DO NOT connect the POTS port on this unit directly to external PSTN line. This unit can only be used with the certified adaptor model inside the package, which complies with the requirement of limited power source. 2.2 Laser Safety Caution!

Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous laser radiation exposure. Invisible laser radiation may be emitted from the ends of un-terminated fiber cables or connectors. Never look directly into an un-terminated cable or connector. Note: This ONT uses a class 1 laser device. 4 220-00602 R10 | October, 2013 Safety Danger!

Personnel handling fiber optic cables must be trained for laser safety. Caution!

Do not bend the fiber optic cable to a diameter smaller than 7.5 cm (3 inches). Doing so may damage the fiber or prevent the signal from passing through properly. 220-00602 R10 | October, 2013 5 User Guide 3 3.1 Installation Get to Know the ONT The figures below show the overview of the ONT.
