Section 1 — Safety Information and FCC Compliance
1.1 Safety Information
Only qualified technical personnel should attempt to install the RFC-1 system. An attempt to
install this device by a person who is not technically qualified could result in a hazardous
condition to the installer or other personnel, and/or damage to the RFC-1 or other equipment.
Ensure that safety precautions are made before installing this device.
The RFC-1 Remote Facilities Controller is registered with the Federal Communications Commission and certified to
meet specific safety requirements. It is extremely important that the RFC-1 not be modified in any way. Modification
of this equipment will void the FCC certification, void the warranty, and perhaps pose a hazard to the user of this
equipment or to maintenance personnel of your local telephone company.
The RFC-1 Remote Facilities Controller should be serviced only by qualified technical personnel who are familiar with
the implications of FCC Part 68 registration. The RFC-1 Remote Facilities Controller and the RP-8 Relay Panels are
designed for indoor use in a dry location. Installation and operation in other locations could be hazardous.
All cables should be disconnected when servicing the RFC-1 system. Extreme caution should be
used when opening the RFC-1 chassis. High voltages may be present on telephone lines.
Although the RFC-1 has a 12-volt AC power transformer, failure of the transformer could cause
dangerous and potentially lethal voltages to become present.
Depending on the installation, the control circuits of the RP-8 Relay Panel may be connected to sources of up to 120
volts AC and/or several amperes of current. Under certain conditions, these voltage sources can be lethal. Always
use caution when working around these circuits. Disconnect all high voltage and high current sources before
servicing the RFC-1 system.
Exercise caution when working near the connectors on the RP-8. The removable connectors used on the RP-8 leave
slightly exposed tips even when the connector is in place. The tips are not dangerous but they are pointed.
Furthermore, the exposed metal provides a very small point where a short could occur. Be careful when using metal
tools near any exposed wiring. Power should be removed form all devices when performing service.
The RFC-1 contains self-resetting "fuses" that protect it from excessive current. If they become damaged,
replacement devices should be of the same type and rating.
The RFC-1, like any electronic device, can fail in unexpected ways and without warning. Do not use the RFC-1 in
applications where a life-threatening condition could result if it were to fail.
