FCC RF Exposure Warning: This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. End-users must be provided with specific operating instructions for satisfying RF exposure compliance requirements. Telephone Company Procedures The goal of the telephone company is to provide you with the best service it can. In order to do this, it may occasionally have to make changes in its equipment, operations, or procedures. If these changes might affect your service or the operation of your equipment, the telephone company will give you notice in writing to allow you to make any changes necessary to maintain uninterrupted service. If you have any questions about your telephone line, such as how many pieces of equipment you can connect to it, the telephone company will provide this information upon request. In certain circumstances, it may be necessary for the telephone company to request information from you about the equipment which you have connected to your telephone line. Upon request of the telephone company, you must provide the FCC registration number and the Ringer Equivalence Number(REN) of the equipment which is connected to your line. Both of these numbers are listed on the equipment label on the bottom of your BT-CT . In most(but not all) areas, the sum of the RENs of all devices connected to one line should not exceed 5. To be certain of the number of devices you may connect to your line as determined by the REN, you should contact your local telephone company. Note: This equipment is hearing aid-compatible(HAC).

Output Power and Channel Separation in Different Operating Modes The different operating modes (data-mode, acquisition –mode) of the Bluetooth cordless phone (called Bluetooth device below) do not influence the output power and channel spacing. There is only one transmitter which is driven by identical input parameters concerning these parameters. Only a different hopping sequence will be used. For this reason the check of these RF parameters in one operating mode is sufficient. Frequency Range of a Bluetooth Device Hereby we declare that the maximum frequency range of this device is : 2402 – 2480 MHz. This is according to the Bluetooth Core Specification V 1.1 for devices which will be operated in the USA. Other frequency ranges (e.g. for Spain, France, Japan) which are allowed according to the Core Specification are not supported by this device. Co-ordination of the Hopping Sequence in Data Mode to Avoid Simultaneous Occupancy by Multiple Transmitters Bluetooth units which want to communicate with other units must be organized in a structure called piconet. This piconet consists of maximum of 8 Bluetooth units. One unit is the master the other seven are the slaves. The master co-ordinates frequency occupation in this piconet for all units. As the master hop sequence is derived from it’s BD address which is unique for every Bluetooth device, additional masters intending to establish new piconets will always use different hop sequences. Example of a hopping sequence in data mode Example of a 79 hopping sequence in data mode: 40, 21, 44, 23, 42, 53, 46, 55, 48, 33, 52, 35, 50, 65, 54, 67, 56, 37, 60, 39, 58, 69, 62, 71, 64, 25, 68, 27, 66, 57, 70, 59, 72, 29, 76, 31, 74, 61, 78, 63, 01, 41, 05, 43, 03, 73, 07, 75, 09, 45, 13, 47, 11, 77, 15, 00, 64, 49, 66, 53, 68, 02, 70, 06, 01, 51, 03, 55, 05, 04. Equally Average Use of Frequencies in Data Mode and Behaviour for Short Transmissions The generation of the hopping sequence in connection mode depends essentially on two input values : 1. LAP/UAP of the master of the connection 2. Internal master clock The LAP (lower address part) are the 24 LSB’s of the 48 bit BD_ADDRESS. The BD_ADDRESS is an unambiguous number of every Bluetooth unit. The UAP (upper address part) are the 24 MSB’s of the 48 bit BD_ADDRESS,. The internal clock of a Bluetooth unit is derived from a free running clock which is never adjusted and is never turned off. For synchronization with other units, only offset values are added to this clock. It has no relation to the time of day. Its resolution is at least half RX/TX slot length of 312.5 μs. The clock has a cycle of a bout one day (23h30). For the deriving of the hopping sequence the entire LAP (24bits), 4 LSB’s (4 bits) (Input 1) and the 27 MSB’s of the clock (Input 2) are used. With this input values different mathematical procedures (permutations, additions, XOR-operations) are performed to generate the sequence. This will be done at the beginning of every new transmission. Regarding shorts transmissions the Bluetooth system has the following behaviours: The first connection between the two devices is established, a hopping sequence was generated. For transmitting the wanted data the complete hopping sequence was not used. The connection ended. The second connection will be established. A new hopping sequence is generated. Due to the fact that the Bluetooth clock has a different value, because the period between the two transmission is longer (and it cannot be shorter) than the minimum resolution of the clock (312.5 μs). The hopping sequence will always differ from the first one. Receiver Input Bandwidth and Behaviour for Repeated Single or Multiple Packets The input bandwidth of the receiver is 1 MHz. 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 (e.g. single or multislot packet) 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 packet has no influence on the hopping sequence. The hoping sequence generated by the master of the connection will be followed in any case. That means, a repeated packet will not be sent on the same frequency, it is sent on the next frequency of the hopping sequence. Channel Separation in Hybrid Mode As mentioned before, the nominal channel spacing of the Bluetooth system is 1 MHz independent of the operating mode. In other words, the channel spacing in hybrid mode (inquiry and page mode) is still 1 MHz without any change. Derivation and Examples for a Hopping Sequence in Hybrid Mode For the generation of the inquiry and page hop sequences the same procedures as described for the data mode are used, but this time with different input vectors: For the inquiry hop sequence, a predefined fixed address is always used. This results in the same 32 frequencies used by all devices doing an inquiry but every time with a different start frequency and phase in this sequence. For the page hop sequence, the device address of the paged unit is used as input vector. This results in the use of a subset of 32 frequencies which is specific for that initial state of the connection establishment between the two units. A page to different devices would result in a different subset of 32 frequencies. So it is also ensured that in hybrid mode the frequency use equally averaged. Example of a hopping sequence in inquiry mode : 48, 50, 09, 13, 52, 54, 41, 45, 56, 58, 11, 15, 60, 62, 43, 47, 00, 02, 64, 68, 04, 06, 17, 21, 08, 10, 66, 70, 12, 14, 19, 23 Example of a hopping sequence in paging mode : 08, 57, 68, 70, 51, 02, 42, 40, 04, 61, 44, 46, 63, 14, 50, 48, 16, 65, 52, 54, 67, 18, 58, 56, 20, 53, 60, 62, …
