Figure 5 Switching Power Supply FM transmitter Installation Instructions Take out of the machine and the antenna (bars or rubber antenna), put the antenna into the machine at the back of the NO 10 antenna interface ANT, make the interface tighten. Take out the power, the power plug into NO 9 power source of the machine If you want to play music and audio files, please use audio line and computer or MP3 audio source such as connection, and then insert the launch of the front NO 2 audio input; Or you want to use a microphone broadcasting, please prepare a common 3.5 interface in the extremely a microphone (computer headset can also be) into No 6 microphone interface (note: can only use in a microphone (such as Mike be used in computer), does not support moving coil type microphone (such as KTV Mike))
FM transmitter operating instructions After above operation steps,the fan back of the machine will open for a few seconds, and then host screen will appear OFF ". Then press No 3 power switch button start machine, the transmitter screen will light up, and then display the current launch frequency, such as 83.00 MZH, the frequency is the frequency of the broadcast transmitter foreign launch, if you want to alter the frequency,press No 4 or No 5 frequency-frequency + buttons to adjustment on the host panel, frequency step value: 0.1 MHz.. If you use audio input methods launch radio, first adjust the audio input the volume of the audio source, such as MP3 audio source for music to broadcast, first the volume of the MP3 player to adjust to the 80% to 90%, and then in the host to launch No 2 audio input sound volume button adjust volume, general volume control at 80% to 90% will get better sound quality, according to your actual condition debugging. Or you use a microphone input methods launch FM radio, prepared a microphone into panel No 6 microphone interface, turn the knob No 7 and the microphone volume adjustment knob, adjust the output of the microphone volume, to your satisfaction. You can use an ordinary FM radio support FM radio to receive and debugging, if you set the transmit frequency is 83MHZ, you can use the radio's 83 MHZ to receive and debugging. Transmitter power control instructions The machine power can be switched between the 0.1W/0.5W. First the power draw, press and hold the power button on the left side of the front panel don't let go, again plugged in, 3 seconds after loosen button switches, screen shows H letters, again through the front panel +-key conversion H or L H stands for 0.5W, L stands for 0.1W; selected to open and then press the left key to confirm, and then enter the frequency range of settings, but also through the +, - button to select the required frequency range, the first set
frequency 108MHZ, then open the key to confirm and enter the low-end 76MHZ, set to open key and then press to confirm, the screen display OFF, that setup is complete, the normal work. Notes :76-82Mhz frequency range of power is not flat, the sound quality is not good at frequencies above 83-108Mhz; Don t alter the transmitter highest and lowest 76 MHz 108 MHz, even if you set up to 200 MHz is also not work. FM transmitter for transmitting distance instructions FM transmitter range related to a lot of conditions and factors: First, the FM transmitter antenna be used: FM transmitter antenna simple divided into "the class" "GP class" "indoor use with a small class", and to get to the launch of the far distance, shall adopt the "car" and "GP" antenna, which depends on your purpose and decide, GP antenna looks like a umbrella of stents, his launch distance is the most ideal; The second is "car" antenna; And the "rubber" and "bars" such as small antenna is indoor use, empty areas farthest distance launch only 300 meters. Second, the FM transmitter power The launch of the transmitter of power and cover is proportional to the area. Round area formula: S = π times round the square of r; formula: S = 2 * 3.14 r2; R says this round radius, can see, radius r into of the original 2 times, the area into the original 4 times. So, the push to come over, transmitter power increase 4 times, four times the area covered also increases, so, the launch radius r will turn into the original 2 times, so, draw the conclusion, launch power increase for the original four times, distance to launch a doubled. Of course, this is calculated value ideal, in fact, want to double the size of the launch distance, the transmit power to increase more than four times, sometimes may be up to 10 times. Third, the FM transmitter use of the environment To 5-watt machine, for example, 5-watt FM transmitter using GP antenna and the antenna mounted on the building's highest point, if there are no obstacles around the case to launch four kilometers away, but if you use in buildings, may also only 1 km from the transmitter, another example of your buildings
more intensive, as well as mobile communication base stations and other electromagnetic interference, it may launch only a few hundred meters of distance. Fourth, the choice of tools to receive You use this machine and use the best "GP antenna" and the use of the environment, you may use a mobile phone with FM radio function to receive, they can only be greatly reduced, and with the common market in the hundred or so radio can receive to 3.5 km of the signal, using a mobile phone is only 2 km. If you listen to with a fever-level tools, such as: handy in 1103, German students PL-600, Kairon's KK-S500 may also be received from the radio at 6 km. The above analysis is for reference only Service The company since buying machine transmitter in the date of 12 months to provide guarantee service, the guarantee period to buy the product warranty card date shall prevail. In normal use, to the non-artificial broken or damaged, buyers can contact the dealer for maintenance.
