Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance will void the user’s authority to operate the equipment. Any change to the equipment will void FCC grant. 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 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. The equipment compliance with FCC radiation exposure limit set forth for uncontrolled Environment

ADB-2388 Bluetooth Earpiece Operating Elements 1. Power supply : Used 3.7V lithium battery (Size 23x12x2.7mm) 2. Charger circuit: U1, C1 and BAT compose the charger circuit. When you link the earpiece with charge port, U1 start working, control the charger current and time, until the battery is full. 3. U1, L4 and C32 compose the power control circuit. When U1’s pin4 get high voltage, L4 can output 1.8V power, supply the U1 and other circuit to work. 4. S5,R5,R4,R6 and C2 compose the ON/OFF circuit, pushing S5 can startup the U1. 5. MIC1,C10,C12,C13,C14,C16,C17,C33,R11,R14,L3 and L5 compose the microphone circuit, can transform the sound signal into electricity signal 6. SPK1 and R9 comose the speaker circuit, can transform the electricity signal into sound signal. 7. D2,D3,R23 and R24 compose the indicator light circuit. 8. ANT1,L1,L2,C4,C5,C6, and U3 compose the antenna circuit. 9. U1,U2,C28,R20,R21,R22,Q3,R18,C25,R19,C257,C24,C23,Y1,C22,C 21,C8,C9,R26,C3 and R27 compose the Bluetooth circuit .

Hopping Information 1 Hopping Range Hereby we declare that the maximum frequency of this device is: 2402-2480MHz. This is according the Bluetooth Core Specification V1.2 (+ critical errata) for devices which will be operated in the USA. This was checked during the Bluetooth Qualification tests (Test Case: TRM/CA/04-E). Other frequency ranges (e.g. for Spain, France, Japan) which are allowed according the Core Specification are not supported by this device. 2 Hopping Sequence Example of a 79 hopping sequence in data mode: 33,04,21,44,23,42,53,46,55,48,40,59,72,29,76,31,08,73, 07,75,09,45,60,39,58,13,47,11,77,52,35,50,65,54,67,56, 69,62,71,64, 37,25,27,66,57,70,74,61,78,63,10,41,05,43, 15,44,64,68,02,70,06,01,51,03,55,05,03,66,53,49,36,47, 3 Receiver input bandwidth The input bandwidth of the receiver is 1MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packer has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence.
