Important Notes
The accessory software updates (MS-NRX series/ MS-DAB100A) are embedded in the MS-AV755/MS-UD755 series update. Once the update has been installed in the stereo, the connected accessory MUST be updated from the 'update' menu screen in the 'settings' menu to be compatible with your Fusion Entertainment System. Please follow the installation instructions (above) or the update download on the product page.
**Please note this software does not work on the MS-AV750 or MS-UD750. If you require the software for either of these products, please manually search for it within the legacy section of our website.

What is the current consumption of my FUSION stereo?
Current consumption of Fusion marine stereos:
Fusion stereos have a standard voltage rating of 10.8V to 16V DC unless otherwise stated.
All figures are for individual head units only, not a system. Numbers can be added together to calculate the system current consumption.
Amplifiers will contribute significantly higher current consumptions.
All marine stereos with 4 amplified speaker outputs have been tested with 4 speakers attached and no USB devices connected.
All measurements are average, so measurements on other production stereos may vary. Values are subject to change without notification.

How do I wire my speakers in 2 Ohm configuration for my compatible Fusion Stereo? (Parallel Configuration)
To wire two 4 Ohm speakers in parallel, to present a 2 Ohm load per channel to a Fusion Class-D 2 Ohm stable stereo, simply follow the below diagram showing the Positive terminals from each speaker connected to each other and the same with the Negative terminals. When this is done, connect the Positive and Negative wires from the closest speaker to the Stereo.

Compatible Fusion Stereos:
- Apollo RA770
- Apollo RA670
- 755 / 750 / 700 Series
- 650 / 600 Series
The Fusion-Link app crashes when I select the volume control icon on the home screen. How can I fix this?
To resolve this issue, delete the Fusion-Link app from your device and then reinstall it.
Why can't I browse my phone's music library from the Fusion-Link app when I am streaming via Bluetooth on my Android device?
Sorry, only Apple devices have the capability to navigate media libraries over Bluetooth.
Why does the Fusion-Link app report "error" when I select "update" from the settings menu?
Over-the-air software updates are only available for the Apollo Series. All other Fusion stereos require a USB stick loaded with an update folder connected to the stereo to perform an update. "Error" will display if there is no USB device connected, the USB device is not formatted correctly, or if the file is not in a folder named "update".
My Fusion-Link wireless application displays "No Stereos Available"
The first thing to check is that you are connected to the correct wireless network for the stereo. Once you have confirmed this, close the app on the device and restart it (consult the manufacturer's website for instructions on restarting). If this fails, check that you have a valid IP address on the stereo and follow the instructions in the tech support item: "My Fusion-link wireless remote Application will not connect to my 700 series stereo."
My Fusion-Link wireless remote application will not connect to my 700 Series stereo.
The first thing to check is that the 700 Series is displaying a valid IP address on the 'about' screen. Select the 'settings' menu, then 'about' to confirm. If the display is "IPNone", the router is either not a compatible DHCP product or is not configured correctly. If the IP address starts with the prefix 169, it is not valid, as this is a default address when the router is not sending a DHCP generated IP address or is configured incorrectly. Please review the router's instruction manual or contact the manufacturer's website for technical help.
