To link two Pro Glow 1500 speakers:
If the sound is distorted: Try lowering the volume control of your sound source or musical instrument. Also, try to reduce the overall volume of Pro Glow 1500.
If there is too much bass: Try adjusting the tone or EQ control from Pro Glow 1500 or your sound source to lower the bass level. This will allow you to play the music louder before clipping (distortion) occurs.
If there is a high-pitched whistling noise when using a microphone: This is probably feedback. Point the microphone away from the speaker.
If you can’t hear the microphone over the music volume: Turn down the music volume from your source.
When I press Previous () or Next (), it doesn’t increment to the next FM station: Short presses of the button will jump to presets. Hold the button down to seek to the next station.
If the radio station channel is flashing: The unit is currently muted. Unmute to stop the flashing and resume playback.
If the Bluetooth logo is flashing rapidly: The unit is currently in pairing mode.
If the Bluetooth logo is flashing slowly: A device is paired, but the music is muted. Unmute to stop the flashing and resume playback.
The USB track number (Example: 001) is flashing slowly: The USB drive music playback is muted. Unmute to stop the flashing and resume playback.
The LCD shows “NONE”: If a USB drive or SD card is already properly inserted, make sure it contains playable files (MP3s, WAVs, and WMA files).
If you cannot connect your audio device to Pro Glow 1500 via Bluetooth:
