Section 1 — Safety Information
!
The DAI-2 Dial-up Audio Interface should be installed only by qualified technical personnel. 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 DAI-2 or other equipment. Please ensure that proper
safety precautions have been made before installing this device.
The DAI-2 Dial-up Audio Interface is registered with the Federal Communications Commission and certified to meet
specific safety requirements. It is extremely important that the DAI-2 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. Service of the DAI-2 Dial-up Audio Interface should
be performed only by qualified technical personnel who are familiar with the implications of FCC Part 68 registration.
The DAI-2 Dial-up Audio Interface is designed for indoor use in a dry location. Installation and operation in other
locations could be hazardous.
Extreme caution should be used if the DAI-2 Dial-up Audio Interface case is opened without first being
disconnected from the telephone line and the DAI-2/RP Relay Panel. High voltages may be present on
telephone lines, and although the DAI-2 is powered by 12 volts AC from a "wall plug" transformer, failure
of this transformer could cause dangerous and potentially lethal voltages to become present. Only the
supplied transformer should be used.
Depending on the installation, substantial voltages may be connected the DAI-2 relay panel. If this is the case, use
extreme care when working in the vicinity of the DAI-2 and disconnect all sources of high voltage before contacting it.
The DAI-2 contains self-resetting "fuses" that protect it from excessive current. If these are replaced, the
replacement devices should be of the same type and rating.
The DAI-2, as any electronic device, can fail in unexpected ways and without warning. Do not use the DAI-2 in
applications where a life-threatening condition could result if it were to fail.
