Regulatory information 25Installation and Maintenance GuideEnhanced 911 configurationRadio-frequency interferenceTelecommunication registrationBCM50 equipment meets all applicable requirements of both Industry Canada CS-03 and USFederal Communications Commission (FCC) Part 68 and has been registered under files IndustryCanada 332D-5980A and FCC US: AB6KF15B20705 (key system), US: AB6MF15B20706(hybrid system), and US: AB6PF15B23740 (PBX system). Connection of the BCM50 telephonesystem to the nationwide telecommunications network is made through a standard networkinterface jack that you can order from your local telecommunications company. This type ofcustomer-provided equipment cannot be used on party lines or coin lines.Caution: Only qualified persons should service the system.The installation and service of this hardware is to be performed only by service personnelhaving appropriate training and experience necessary to be aware of hazards to which theyare exposed in performing a task and of measures to minimize the danger to themselves orother persons.Electrical shock hazards from the telecommunication network and AC mains are possiblewith this equipment. To minimize risk to service personnel and users, the BCM50 systemmust be connected to an outlet with a third-wire ground.Service personnel must be alert to the possibility of high leakage currents becomingavailable on metal system surfaces during power line fault events near network lines.These leakage currents normally safely flow to Protective Earth ground through the powercord. Therefore, it is mandatory that connection to an earthed outlet is performed first andremoved last when cabling to the unit. Specifically, operations requiring the unit to bepowered down must have the network connections (central office lines) removed first.Warning:Local, state and federal requirements for Emergency 911 services support by CustomerPremises Equipment vary. Consult your telecommunication service provider regardingcompliance with applicable laws and regulations.Warning: Equipment generates RF energy.This equipment generates, uses, and can radiate radio-frequency energy. If not installedand used in accordance with the installation manual, it may cause interference to radiocommunications. It has been tested and found to comply with the limits for a Class Acomputing device pursuant to Part 15 of the FCC Rules and with ICES.003, CLASS ACanadian EMI Requirements. Operation of this equipment in a residential area is likely tocause interference, in which case the user, at his or her own expense, will be required totake whatever measures may be required to correct the interference.
