Original texts as following:

Sample Operation Description Sample Operation Description For Class B Note: 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 pro-

vide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not in-

stalled 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. The 24MHZ Hz crystal oscillator drives the base of Y2. The modulation provided by IC TXC-7M-32.000MEEQ-T. The output of has the match-

ing network consisting of balun 2450BM14G0011 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 2.4GHz Meander line SWRU120C antenna. Antenna gain: 1.1 to 3.3 dBi. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by Input VCC;

Output: 3.3 Vd.c.. Operation Descriptions The transmitter is a Portable Wireless Music System operating at 2400-2483.5MHz band. The transmitter is powered by 3.3 Vd.c and the transmitting frequency is crystal controlled. The operation is achieved by different combinations of form pulse modu-

lating signal on the 2400MHz carrier frequency. When the NTAG is positioned in the RF field, the high speed RF communication inter-

face allows the transmission of the data and enable the Bluetooth pairing

modulation/data inputs (if such inputs are provided)

to ensure that the module will comply with Part 15

requirements under conditions of excessive data

rates or over-modulation.

The modular transmitter must have its

own power supply regulation.

The modular transmitter must comply with the

antenna and transmission system requirements of

Sections 15.203, 15.204(b) and 15.204(c). The

antenna must either be permanently attached or

employ a “unique” antenna coupler (at all

connections between the module and the antenna,

including the cable). The “professional installation”

provision of Section 15.203 is not applicable to

modules but can apply to limited modular approvals

under paragraph (b) of this section.

The modular transmitter must be tested in a stand-

alone configuration, i.e., the module must not be

inside another device during testing.

The modular transmitter must be labeled with its

own FCC ID number, and, if the FCC ID is not visible

when the module is installed inside another device,

then the outside of the device into which the module

is installed must also display a label referring to the

enclosed module.
