Compliance Statement (Part 15.105(b)) 

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 

 

Warning: 

IMPORTANT FCC NOTICE to USERS 

Changes or modifications not expressly approved by this company could void the user’s authority to operate the 
equipment. 

B.2 

Europe (ETSI) 

If the device is incorporated into a product, the manufacturer must ensure compliance of the final product to the 

European harmonized EMC and low-voltage/safety standards. A Declaration of Conformity must be issued for each of 

these standards and kept on file as described in Annex II of the R&TTE Directive. 

The manufacturer must maintain a copy of the device documentation and ensure the final product does not exceed the 

specified power ratings, antenna specifications, and/or installation requirements as specified in the user manual. If any 

of these specifications are exceeded in the final product, a submission must be made to a notified body for compliance 

testing to all required standards. The “CE“ marking must be affixed to a visible location on the OEM product. The CE 

mark shall consist of the initials "CE" taking the following form: 

 

If the CE marking is reduced or enlarged, the proportions given in the above graduated drawing must be 

respected 

 

The CE marking must have a height of at least 5mm except where this is not possible on account of the nature 

of the apparatus 

 

The CE marking must be affixed visibly, legibly, and indelibly 

More detailed information about CE marking requirements you can find at "DIRECTIVE 1999/5/EC OF THE 

EUROPEAN PARLIAMENT AND OF THE COUNCIL" on 9 March 1999 at section 12. 

B.3 

Approved antenna 

The device has been tested and approved for use with the antenna listed below. The device may be integrated with 

other custom design antennas which OEM installer must authorize with respective regulatory agencies. The used 

antenna is connected to the radio module via an SMA connection.
