Installation Applications
This product is designed for operation in
12 volt, negative-ground electrical systems.

certified or approved for use in aircraft.
Safety Considerations
• Whenever possible, mount this product
in a dry, well-ventilated location that does
not interfere with other factory installed
electronic devices. If a dry environment is
not available, a location that is not exposed
to heavy splashing may be used.
• While this product is designed to be water-
resistant, it should never be submerged
under water for prolonged periods or
subjected to high-pressure water spray.
• Do not mount in an engine compartment
or in any areas of extreme heat.
• Ensure this product is securely installed so
that it does not come loose in the event of a
collision/sudden jolt or as a result of repeated
vibrations during normal operation.
• Check before drilling to make sure that you
will not be drilling into an exterior panel/
hull, fuel tank, gas/brake line, wiring harness,
or other vital system.
• Do not run system wiring outside or
underneath the vehicle/vessel. This is an
extremely dangerous practice, which can
result in severe damage/injury.
• Protect all system wires from sharp
edges (metal, fiberglass, etc.) by carefully
routing them, tying them down and using
grommets and loom where appropriate.
• Secure all wiring as needed, using cable
ties or wire clamps to protect them from
moving parts and sharp edges.
• Do not replace the power wire fuse with one
of a different value. Never bypass the fuse.
Mounting & Installation
The design of the MBT-CRXv2 requires just
a single hole for installation. Its easy-to-
use threaded-collar mounting system can
accommodate installations in flat surfaces up
to 1.75 inches (4.5 cm) thick. A front-mounted
adaptor plate is included for installations in
panels exceeding 1.75 inches (4.5 cm) thick,
or where rear access is limited or not possible.
