2 SAFETY TRAINING INFORMATION 
 
The M/A-COM P5400 portable radio generates RF electromagnetic 
energy during transmit mode.  This radio is designed for and 
classified as “Occupational Use Only,” meaning it must be used only 
during the course of employment by individuals aware of the 
hazards and the ways to minimize such hazards.  This radio is NOT 
intended for use by the “General Population” in an uncontrolled 
environment. 
The P5400 portable radio has been tested and complies with the FCC RF exposure 
limits for “Occupational Use Only.”  In addition, this M/A-COM radio complies with 
the following Standards and Guidelines with regard to RF energy and electromagnetic 
energy levels and evaluation of such levels for exposure to humans: 
•  FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with 
FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. 
•  American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety 
Levels with Respect to Human Exposure to Radio Frequency Electromagnetic 
Fields, 3 kHz to 300 GHz. 
•  American National Standards Institute (C95.3 – 1992), IEEE Recommended 
Practice for the Measurement of Potentially Hazardous Electromagnetic Fields – 
RF and Microwave. 
2.1  RF EXPOSURE GUIDELINES 
CAUTION
 
To ensure that exposure to RF electromagnetic energy is within the 
FCC allowable limits for occupational use, always adhere to the 
following guidelines: 
•  DO NOT operate the radio without a proper antenna attached, as this may damage 
the radio and may also cause the FCC RF exposure limits to be exceeded.  A 
proper antenna is the antenna supplied with this radio by M/A-COM or an antenna 
specifically authorized by M/A-COM for use with this radio. 
•  DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”).  
Transmitting more than 50% of the time can cause FCC RF exposure compliance 
requirements to be exceeded.  The radio is transmitting when the “TX” indicator 
appears in the display.  The radio will transmit by pressing the “PTT” (Push-To-
Talk) button. 
•  Always transmit using low power when possible.  In addition to conserving 
battery charge, low power can reduce RF exposure. 
•  ALWAYS use M/A-COM authorized accessories (antennas, batteries, belt clips, 
speaker/mics, etc).  Use of unauthorized accessories may cause the FCC 
Occupational/Controlled Exposure RF compliance requirements to be exceeded. 
•  As noted in 
Table 1-1 ALWAYS keep the device and its antenna AT LEAST 1.1 
cm (0.43 inches) from the body and at least 2.5 cm (1.00 inch) from the face when 
transmitting to ensure FCC RF exposure compliance requirements are not 
exceeded.  However, to provide the best sound quality to the recipients of your
