Dear Sir/Madam,

We, Cobra Electronics Corporation hereby declare that we have a product named as CB Radio, (model:29 LX, FCC ID: BBO29LX) were tested by BACL. For our marketing purpose, we would like to list a series model (29LXOEM B) on reports and the certificate.

The difference between the base model 29 LX and the 29 LX OEM B is a mechanical tooling change to the Front panel on the 29 LX OEM B where the “chin” under the channel selector has been flattened to improve installation in certain vehicles and the giftbox image includes this tooling change.

Aside from the difference noted, all internal electronic and remaining mechanical components are identical.

We confirm that all information above is true, and we’ll be responsible for all the consequences.
