3. FCC Information to User
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
This device complies with Part 15 of FCC Rules.
Operation is subject to the following two conditions:
(1) the device may not cause interference, and
(2) the device must accept any interference, including interference that may cause
undesired operation of this device.
4. WARNING TO USER
－ Change or modifications not expressly approved the manufacturer can void the
user's authority to operate this equipment.
－ This equipment must not be co-located or operated in conjunction with any other
antenna or transmitter.
This equipment complies with FCC radiation exposure limits set forth for uncontrolled
equipment and meets the FCC radio frequency (RF) Exposure Guidelines in
Supplement C to OET65. This equipment must be installed and operated with at least
20cm and more between the radiator and person’s body (excluding extremities: hands,
wrists, feet and ankles).

5.Reader, Anrenna Troubleshoot Guide
5.1 Fixed Reader and Antenna Troubleshoot
1. Confirm the demage of the out case and the inundation.
1) check the external connector .
2) check the inundation .(Check the clearance of the reader)
2. Confirm the reader setup program.
1) The reader setup is the execution of the reader manager program
3. Confirm the error of the power.
1) Check the adaptor
(The output power is 5v dc)

2) Check the connection of the ac adapter to the reader.
3) Confirm the red LED of the reader
4) If the red LED is off, the power is not supplied.
Check the connection of the ac power cord.
Change the output of the ac/dc adapter.
4. Confirm the LAN connection.
1) Confim the yellow LED.
