August 10, 2010 Timco Engineering 849 NW State Road 45 P.O. Box 370 Newberry, FL 32669 Ref: FCC ID: BBO3K229LTDW To Whom It May Concern:

Cobra Electronics Corporation requests a declaration of continued compliance for changes made to the display and control unit of a CB radio currently approved under BBO3K229LTDW. Since these changes are not to the CB receiver or transmitter, we submit this as a Class II permissive change under the provisions of 47 CFR 2.1043. For the purpose of increasing sales of the product, the following changes are made:

1) The LED and mechanical switches on the front panel of the unit are replaced by an LCD display with microprocessor control PCB. 2) The transceiver PCB is slightly modified to interface with the new front panel assembly. Samples have been provided to Timco, and measurements of these samples confirm that transceiver parameters and emissions remain within limits. Sincerely, Ron Kabler Director, Engineering Cobra Electronics Corporation
