FCC Part 15 Warning THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. NOTE: THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT. IC RSS-GEN, Sec 7.1.2 Warning Statement Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope rayonnée quivalente (p.i.r.e.) ne dépassepas l’intensité nécessaire à l’établissement d’une communication satisfaisante. 109 GRAMOVOX DETAILED SPECIFICATIONS LOUDSPEAKER DRIVER: 1.5” (38mm) Horn Loaded Full Range MAGNET: Neodymium (Magnetically Shielded) Impedance: 8 ohm CONE TYPE: Paper (w/ Mylar dust cap) BLUETOOTH VERSION: 4.0 (backwards compatible with Bluetooth 3.0, 2.1, 2.0) FREQUENCY: 2.4GHz PROFILE: A2DP RANGE: 30ft (~10m) ANTENNA: Internal POWER BATTERY: Built in 3.7V Li-Ion battery (3300mAh) PLAYBACK TIME: 12 to 18 hours CHARGING TIME: 3 to 4 hours CHARGER TYPE: Micro USB B Off- line USB charger (1A) PHYSICAL PROPERTIES HORN DIAMETER: 10.64 in.
