LEDS
The RFID board has 5 LEDs that indicate whether or not the RFID system is working. The table
below defines each LED and its function.
LED Label Color Light Status Description

receives data to and from the entry unit

constantly lit.

Tips and Suggestions
The ReachFree ID reader uses the 900 MHz frequency which can cause interference with
other electronic devices that use the 900 MHz frequency range. Unitec strongly suggests you
observe the following warnings:

Stay away from UHF communications devices.

Avoid arc lighting fixtures by 3 or 4 feet.

Keep neighboring long-range readers on parallel lanes at least 12 feet apart, with
their surveillance zones parallel to each other.
 Do not have identical readers facing each other (but “back-to-back” is OK).
