INSTALLATION WARNING
• Ensure the marine v12V lead is removed from the battery
before any equipment is connected
• Investigate the marine vessels fuel tanks and electrical wiring
locations before you begin installation
• Ensure all wiring is protected to avoid damage
When wiring the MS-RA205, ensure that the wires are away from sharp objects and
that rubber grommets and insulated bungs are used when routing the wiring. Ensure
that when connecting the wires to the speakers and audio system, the terminals and
connections are protected from shorting to each other.
Note:
Ensure the antenna cable is routed away from any power cables, and is the minimal
length, as long cable runs will affect AM reception performance.
For optimum radio reception please ensure you use a dedicated AM/FM ground
independent marine antenna.

ELECTRICAL ISOLATION OF THE MS-RA205
The MS-RA205 stereo has a metal chassis which is connected to the Ground /
Negative / Black wire (like most other stereos).Extra care should be taken when
installing this type of stereo in an aluminium boat or boats with a conductive hull if
you require the electrical system to be isolated from the boat hull.
