Why is my Neptune freezing?

If the Neptune is freezing or running slow, there may be non-compatible songs on the device. With the Neptune plugged into the computer, open up the “FINIS” drive and make sure the ‘Type’ column is visible to view the song types. Delete any non-compatible songs off of the “FINIS” Drive.

If your Neptune continues to freeze, you may need to reset the unit. Press and hold the ‘Back’ Button for 12 seconds. The Neptune will automatically power off.

I am listening to an audio book on my Neptune in ‘Play All’ mode, but the chapters are not playing in order?

If you need the audio books or songs to play in order (while in ‘Play All’ mode), ensure that you copy a folder of songs and not each song individually onto the FINIS drive.

My Neptune doesn’t have 8 hours of playback time. Am I doing something wrong?

By default the Neptune will have 8+ hours of playback, but the amount of playback time will vary based on volume you set on the Neptune. The higher the volume, the less playback you will have. Having the screen active will also reduce the playback time. To optimize battery life, navigate to the settings. Change the Screen Saver to 10 seconds and the Power Save to 1 minute.

I am using a Mac OS and it says that my Neptune is full even after I’ve deleted all the songs. What am I doing wrong?

You will need to empty out your trash after deleting songs to free up the deleted space on your Neptune. This needs to be done while your Neptune is plugged into your computer before disconnecting.

Proper Care

• Pat dry and store in safe, cool, dry environment.
• Do not place Neptune in direct sunlight to dry. This may cause damage to the casing, battery and charging pins.
• Take care to NOT depress buttons with sharp edges such as a fingernail. Sharp edges may puncture the button surface and cause water damage.
• Neptune device is waterproof to 10ft or 3m and can be safely used in swimming pools, lakes, oceans or any fresh/salt water bodies of water.
Fitting Guide
• Open the clips on the side unit and slide up onto your goggle straps. Make sure the unit is flush against your head.
• It is recommended that the bone conduction speakers be placed in front of the ear and not over your ear, resting against your temple bone for ideal clarity.
• Neptune is best heard underwater where no air is present. Wearing ear plugs will not only block noise you hear above the water, but it will also enhance the music quality while swimming.
