FCC 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 1: 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. NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Operational Description

Circuit Description When the bluetooth speaker connects to another device, the device send the music to the bluetooth speaker via the bluetooth. The working state of the bluetooth speaker indicate by the LED. There are Multi-function Button, Volume up button and Volume Down button for you to increase the volume or decrease the volume of the speaker. The product has a USB Port, the USB port only use for battery charging. The operating voltage is battery 3.7V. The bluetooth speaker based on IS1621N-152 chipset, It is compliant to Bluetooth v2.1 + EDR specification. U1(IS1621N-152) is a single chip and baseband IC for Bluetooth systems. It works with a crystal Y1(16MHz) The frequency of the bluetooth speaker is 2402-2480MHz Antenna Specification: Type of Antenna: PCB Antenna Frequency Range: 2402-2480MHz Maximum Gain: 0 dBi Impedance: 50 ohm Size: 9mm x 4mm Antenna View Top Bottom Antenna Location Top Bottom

RF Exposure Info

SEENDA TECHNOLOGY CO., LTD Model: IBT-01 REPORT NO.: STR12088167I PAGE 9 OF 52 FCC PART 15.247 4. RF Exposure 4.1 Standard Applicable According to the KDB-447498, the RF exposure evaluation shall to demonstrate compliance. 4.2 Test Result Tx frequency range: 2402~2480MHz Device category: Portable device Maximum Output Power: 1.619mW (2.093dBm/2402MHz/GFSK) Limit: 60/f(GHz) mW = 24.98 mW Source-based time-averaged conducted output power is 1.619 mW =< 60/f So the transmitter complies with the RF exposure requirements and the SAR is not required.
