wireless microphone may interfere with other devices and cause damage.
• Thls product is a precision instrument. Do not drop, subject it to impact or
excessive vibration.
• Keep this product away from extreme cold or high temperatures, and away
from humidity.
• Use wireless equipment only in areas where permitted.
• If playback equipment (such as speakers and amplifiers) is placed next to the
microphone during recording, feedback may occur. Move the device further
away from the microphone or reduce the volume.
• If the microphone power is turned off, or the receiver and microphone
transmitter are not connected when starting to record, there may be noise or
no sound. Make sure indicators on the receiver and microphone are lit in blue,
and that the two devices have connected properly, then begin to record.

multiple 2.4G devices.Try to use in a quiet environment so
that low/high frequency noise is not captured by the mic.
