Notes for operation � MV-P618 is a high-sensitivity microphone designed to give optimum performance. This is designed to give best performance at a certain distance from the source. Do not locate your microphone too close to the source. Otherwise the tone balance is disordered due to the proximity effect. � A loud sound near the microphone may cause to distort the sound signal due to the built-in mic amp of the camera. In addition, the sound level may fluctuate due to AGC of VCR. (Adjust the volume control of the camera to avoid sound signal distortion.) � When this unit is used on the GY-DV300, it may pick up the operating noise of the camera. To reduce this noise, set the menu item of the GY-DV300 WIND CUT in the SYSTEM [1/2] to ON. In this case, however, note that low frequencies may not be picked up properly. � While recording, always monitor the sound level with headphone etc. � Do not wet the microphone. (Especially when using in rainy conditions.)
