-3 207.6 FCC Warning Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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: 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.

Circuit Description In the transmitter, Signal according to dynamic cartridge oscillate to change audio signal input to processor. 31101 is for the signal compress and the oscillator, which can output twelve encoding signals corresponding to the working states. And the last frequencies are 180 and 207.6MHz. The transmitter is using “6F22”9V battery. At the receiver, the signal take back and oscillate fundamental frequency and frequency mixing, after will have 10.7MHz frequency decoding audio signal. One is audio signal amplifier, and according to the switch to 31101 audio amplifier to output. Another audio signal is no any input signal, and the decoder input the noise, after amplifier the noise can use signal, and test, to control the switch. MISHA 2015-09-25

Tune up procedure of microphone MA-338 1.Connect the power of 9V, to check whether the electric current can be normal or not. 2.Use debugger tone and coil inductor week, the main wave power and harmonic voltage raised to the highest. The max target power is 2mW. 3.Adjust the frequency to the desired frequency. 4.Connected to the low-frequency signal generator to the MIC inputs, in order to see the waveform whether can be normal or not. Adjusted to the desired maximum modulation. 5.Detection switch function whether can be normal (mute in energy). 6.If there are some Low pressure indication, try to adjust to the low voltage power supply to check the indicators whether can be normal or not. 7.
