COMPLIANCE WITH RF EXPOSURE STANDARDS
Your RCA portable two-way radio is designed to comply with a number of national and
international standards and guidelines (listed below) regarding human exposure to RF
electromagnetic energy. This radio complies with the Institute of Electrical and Electronic
Engineers (IEEE), FCC and the International Commission on Non-Ionising Radiation Protection
(ICNIRP) exposure limits for Occupational/Controlled RF exposure environment at duty factors
of up to 50% talk, 50% listen and is authorized by the FCC for occupational use. In terms of
measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates
measurable RF energy only while it is transmitting (during talking), not when it is receiving
(listening) or in standby mode.
Your RCA two-way radio complies with the following RF energy exposure standards and
guidelines:
• United States FCC, Code of Federal Regulations; 47CFR Part 2 Sub-part J
• American National Standards Institute (ANSI)/IEEE C95. 1-1992
• IEEE C95.1-1999 Edition
• Industry Canada RSS-102
RF EXPOSURE COMPLIANCE AND CONTROL
GUIDELINES AND OPERATING INSTRUCTIONS
To control exposure to yourself and others and to ensure compliance with the Occupational/
Controlled environment exposure limits, always adhere to the following procedures.
GUIDELINES:
• User awareness instructions should accompany the device when transferred to other users.
• This radio meets the FCC RF exposure guidelines when used with the RCA accessories
supplied or designated for the product. Use of other accessories may not comply with the
FCCs RF exposure guidelines and may violate FCC regulations.
• Do not use this device if the operational requirements described herein are not met.
INSTRUCTIONS:
• Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), press the
Press-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the
time, or less, is important because this radio generates measurable RF energy exposure only
when transmitting (in terms of measuring for standards compliance).
• Do not operate the radio without an approved antenna attached, as this may cause the FCC RF ex-
posure limits to be exceeded. With this product, use only an antenna supplied or approved by RCA.
