Quick Start Guide 
7  Safety Instructions 
 
7.1. 
Power Disconnect Device 
The plug on the power supply cord is intended to be the power disconnect 
device. As a result, the power source (socket or outlet) shall be located near 
the equipment and shall be easily accessible.
7.2.  RF Safety 
 
WARNING: 
Part 90 Radiation Exposure Statement. The antennas used for this transmitter 
must be installed to provide a separation distance of at least 1 meter from all 
persons and must not be co-located or operating in conjunction with any other 
antenna or transmitter. 
 
 
 
Caution: 
The 3M Toll RFID Reader 6204 UHF Reader is equipped with four (4) RF 
ports. To prevent reader damage, active RF ports must be properly 
terminated with a 50 ohm load or a functional UHF antenna before power up. 
UHF Readers are factory configured to operate on RF port 1. As a result, port 
1 must be properly terminated before initially powering on the reader. Before 
activating any additional RF ports, they must also be properly terminated. 
Never power up the reader unless the appropriate loads or antennas are 
connected. Always power down the reader before removing an antenna or 
load from an RF port. 
7.3.  Electrostatic Discharge 
 
ATTENTION 
3M Toll RFID Reader 6204 antenna ports may be susceptible to 
damage from static discharge or other high voltage. Use proper 
Electrostatic Discharge (ESD) precautions to avoid static discharge 
when handling or making connections to the 6204 reader antenna or 
communication ports. Equipment failure can result if the antenna or 
communication ports are subjected to ESD. 
7.4.  Regulatory Compliance 
 
Caution: 
The 3M Toll RFID Reader 6204 is designed to meet the regulatory 
requirements in those jurisdictions in which it is offered. Changes or 
modifications not expressly approved by 3M for compliance could void the 
user's authority to operate the equipment.
