Installing the AR400
Mounting Tips
Consider the following before selecting a location for the AR400 reader:
• Mount the AR400 indoors, in operating range, and out of direct sunlight, high moisture, or extreme
temperatures.
• Mount the AR400 in an area free from electromagnetic interference. Sources of interference include
generators, pumps, converters, non-interruptible power supplies, AC switching relays, light dimmers, and
computer CRT terminals.
• Mount the AR400 within 15 feet of the antennas.
• Ensure the AR400’s power cord can reach the power source outlet.
• Mount the AR400 onto a permanent fixture, such as a wall or a shelf, where it won't be disturbed,
bumped, or damaged. Allow a minimum of five inches of clearance on all sides of the AR400.
