Be sure the speakers and transmitter are set to the same channel.
If the transmitter is connected to an audio source’s headphone
jack, reduce the audio source’s volume.
Change the position of the transmitter.
The speakers are placed beyond the transmitter’s effective
range (approximately 300 feet). Move the speakers closer to the
transmitter.
Other 900 MHz transmissions are being picked up by the speaker’s
receiver (possibly from a 900 MHz cordless telephone). Change the
transmitter’s and the speaker’s frequency channel.
The speaker’s batteries are low. Replace the batteries.
