Radiation exposure statement
CAUTION: The radiated output power of this device is below the FCC radio frequency exposure
limits. Nevertheless, this device should be used in such a manner that the potential for human
contact during normal operation is minimized. This device has been evaluated for and shown
compliant with the FCC RF Exposure limits under mobile exposure conditions (antennas are
greater than 35 cm from a person’s body). Details of the authorized configurations can be
found at https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm by entering the FCC ID
number on the device.

SONICWALL declares that the APL28-0B5 (FCC ID: 2AKCZ-0B5) when sold in the USA is limited to CH1~CH11 by
specified firmware controlled in the USA.
CAUTION: This device is restricted to indoor use due to its operation in the 5.15GHz to 5.25GHz
frequency range. The FCC requires this product to be used indoors for the frequency range
5.15GHz to 5.25GHz to reduce the potential for harmful interference to co-channel Mobile
Satellite systems.
High power radars are allocated as primary users of the 5.25GHz to 5.35GHz and 5.65GHz to 5.85GHz bands.
These radar stations can cause interference with this device or can cause damage to this device, or both. The
APL28-0B5 device has been designed to operate with an antenna having a maximum gain of 2.5 dBi for R-TNC
and R-SMA is 3.0 dBi. Antenna having a higher gain is strictly prohibited. The required antenna impedance is 50
ohms.
Dynamic Frequency Selection (DFS) is required on all Wireless LAN Master devices (usually Access Points) and
Wireless LAN Clients (usually Wireless NICs) that operate within 5470MHz – 5725MHz. SonicPoints that have
these frequencies and channels enabled in this range comply with North American and International DFS
requirements. Some frequencies are blocked, and cannot be selected by the user per each specific regional
approval.
Specific to the USA, at the urging of the Federal Communication Commission (FCC) user/installers should avoid
operation frequencies near Terminal Doppler Weather Radar (TDWR) systems frequencies 5600-5650 MHz when
installing a SonicPoint within 35km of line-of-site of TDWR sites. If TDWR is within 35km the SonicPoint,
frequencies should be set to at least 30MHz above or below any TDWR system frequency at that site. TDWR
locations and specific frequencies used can be found at http://spectrumbridge.com/udrs/home.aspx. Detailed
current and background information can be found at http://www.wispa.org/?page_id=2341.
