Using a flat head screw driver or edge of a coin (a quarter may be used), remove the screw securing the back battery panel. 3. Insert the supplied three AA rechargeable batteries or non-rechargeable alkaline batteries. Position batteries according to polarity markings. 4. Replace battery compartment cover, screw and belt clip. • Do not attempt to charge alkaline batteries. • Do not mix old and new batteries. • Do not mix alkaline, standard (carbon-zinc), or rechargeable (Ni-Cd, Ni-MH, etc.) batteries. To charge batteries in radio: 1. Check to see that the batteries have been inserted properly. 2. Insert the cable into the charge jack located at the top of the radio. 3.

September 19, 2014 Equipment Authorization Division Office of Engineering and Technology Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Ref: FCC ID: BBO2146A Dear Sirs: Cobra Electronics Corporation requests acceptance of the labeling proposal described below for the transceiver bearing FCC identifier BBO2135A. The subject transceiver is a compact handheld model, authorized under 47CFR Part 95 for FRS and GMRS services. Because the majority of the transceiver housing is composed of display, speaker, operating controls, and a battery access cover, there is extremely limited space available to attach the required label carrying the FCC identifier. Attaching the label to the battery access cover is not acceptable because the battery access cover is a removable item. For this reason, Cobra proposes placing the label carrying the FCC identifier inside the battery compartment as shown in figure 1. Figure 1. The consumer packaging for these models includes the batteries as separate items, NOT installed in the radio. As such, the FCC identifier will be readily visible to the user before the batteries are installed and whenever the batteries are removed or replaced. In this location, the label will also be protected from physical abuse and remain readable for the anticipated life of the device. The consumer packaging for these models is a transparent plastic "clamshell" but, because the battery access cover is installed on the radio, the battery compartment cannot be seen at time of purchase. In order to meet the requirements of 47CFR Part 2.925 (d), Cobra will add the FCC identifier "BBO2146A" to the insert card within the clamshell packaging. Sincerely, Chris De Waal Sr. Project Engineer
