Caution: ( boot the machine into normal operation after 3 seconds )

1, using the microphone : Be sure to turn off the stereo mode, otherwise the volume is small does not work. Microphone plug must be inserted in place , otherwise it will not have sound. Try to use the machine configuration microphone , try to use a little better quality when using other microphone. Do not use a microphone wire length of less than 50 cm ( wire antenna doubles ), otherwise very close.

 

2, the transmitted audio signal : the transmitter when other audio signals such as MP3 / computer / TV audio and other signals must turn on the stereo mode to match the volume attenuation , distortion otherwise great . Use a length greater than 50 cm stereo audio cable to connect the transmitter and the device and adjust the volume of the receiving device the best sound quality . To increase the transmission distance , should be allowed to adopt a longer audio cable stretched away from metal objects.

 

3, on the launch distance : Test conditions for unobstructed open to receiving Desheng PL-600 radio, radio antenna all the way out , microphone leads naturally stretch , able to receive the most distant sound. Due to the actual use of the environment and radio performance may differ from the actual effect is quite different . Doubles as a transmitting antenna wire due to the use of the microphone , so try to stretch out to enhance the emission effects.

 

4 , Volume Adjustment : Volume control is the key to the operation. Excessive sound will sound distorted or appear very hoarse howling , the volume is too small receiving end sound weak or unclear . First person to determine the distance of the mouth and the microphone as close to the same person and the mouth , and then adjust the volume. If the microphone and mouth from people changing the microphone volume to re- adjust the receiving end sound clarity. Recommendations about the microphone volume 5 launch and close the stereo mode. Signal should be emitted MP3 stereo mode reasonable adjustments , such as using the device and transmitter receives the sound volume to make the most clear.

 

5, on the transmit power : For PureFM-980P transmitter , since the transmission power is large, especially in the case of three transmit power , the host will be able to feel the heat a few minutes after use , this is normal , do not worry. Host shell maximum temperature and the temperature difference between the ambient temperature does not exceed 10 degrees. Due to the large transmit power, should avoid opening the absence of a microphone plugged host to avoid black. High-power radio transmitter distance should be greater than five meters away from the radio to avoid damage . Distance should be enough for the case of small files using power transmission to extend battery life.
