FCC Warning statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
You are cautioned that changes or modifications not expressly approved by the party responsible for
compliance could void your authority to operate the equipment.
2/75
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may cause undesired
operation
2 Installation Instructions
When you install the platform, make sure that the USB port of the module is connected to the platform USB i n
order to ensure the normal functioning.
3 CONFIGURATION
RT5370 RT3070 driver can be configured via following interfaces, i.e.
1. configuration file
2. "iwconfig" command
3. "iwpriv" command
Note:
1) modify configuration file "RT2870STA.dat" in /etc/Wireless/RT2870STA/RT2870STA.dat.
2) iwconfig/iwpriv comes with kernel.
3) iwpriv use, please refer to below sections for details.
3.1 Configuration File RT 2870STA.dat
# Copy this file to /etc/Wireless/RT2870STA/RT2870STA.dat
# This file will be read on loading driver module.
#
# Use "vi RT2870STA.dat" to modify settings according to your need.
#
#
#The word of "Default" must not be removed
