The MRF40 is IPx7-certified for water resistance, plus it even floats, so it's the ideal remote for boating. Detachable lanyard included. Warranty: 1 year.

Compatibility: The Dual MRF40 marine remote control is compatible with Dual RF remote-ready marine head units (sold separately). The included RF receiver plugs into the 3.5mm minijack remote input of your compatible head unit. The receiver box also contains power/ground leads which need to be hardwired to your head unit's harness. Up to five MRF40 remotes can be paired to a single head unit.

Marine Rated: The Dual MRF40 is marine certified and meets IXP7 standards (waterproof up to 3.2'). It also features UV resistant plastic and floats on water.

RF Remote: The Dual MRF40 marine remote uses RF (radio frequency) to communicate with your compatible Dual RF remote-ready head unit (up to 30' away). No direct line of sight needed.

Remote Controls: The MRF40 remote  includes controls for Volume up/down, Mute, Track forward/backward, and Source/Mode selection.

3V Battery: The MRF40 operates off of a single CR2032 3V "coin-type" battery that comes pre-installed. The battery is replaceable.

Detachable Lanyard: The Dual MRF40 comes with a detachable lanyard to keep around your neck or wrist.

Mounting Options: The included RF receiver should be mounted away from hot or moving parts, and a location that is protected from splashing water. Mounting the receiver in a higher location will ensure maximum RF signal range. Two mounting screws are included.
