User manual ALPINE MRV-F407

[. . . ] When problems occur such as a lack of sound or video, foreign objects inside the unit, smoke coming out, or noxious odors, stop use immediately and contact the dealer where you bought the equipment. Operating the equipment may distract the driver from looking ahead of the vehicle and cause accident. Always stop the vehicle in a safe location before operating this equipment. Route the cables and wiring so as not to be crimped by moving parts or make contact with sharp or pointed spots which might damage the wiring. [. . . ] ⷠKeep the battery power leads as far away from other leads as possible. ⷠConnect the ground lead securely to a bare metal spot (remove the coating if necessary) of the car chassis. ⷠIf you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various Alpine noise suppressors, contact them for further information. ⷠYour Alpine dealer knows best about noise prevention measures so consult your dealer for further information. Do not use the speaker (­) terminals as a common lead between the left and right channels. 2 RCA Input Jacks Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left and Right to Right. 5 Battery Lead (Sold Separately) Be sure to add a 5 80 amp fuse as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, the wire gauge should be AWG8 or larger. (In this case, the fuse and line choke inside the amplifier do not work. ) When making connection, remove the black cover of the battery direct terminal and use the screw attached to the battery terminal. If used, LED may show abnormal display or the vehicle may be damaged due to the amplifier internal fuse not working. ⷠBe sure to add the fuse with the same capacity as that of the amplifier to the lead for connecting to the battery or battery direct terminal. If alternator noises are found in use, add an external line choke or stop to use the battery direct terminal and reconnect to the battery terminal. ⷠWhen using this terminal, always consult with a specialist to get an advice. 7 Remote Turn-On Lead (Blue/White) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. 8 Ground Lead (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle's chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (­) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops. Cautions on wire lead connections When using third-party wire cables (power supply cord), use the supplied hex screws and the hex wrench to simplify the connection. [. . . ] At that point, reduce the volume one step so the distortion is no longer audible. Keep head unit output at this level and begin increasing the amplifier gain until the maximum output level you desire is reached. To prevent damage to the speakers or amplifier, the maximum output level should not cause bottoming of the speakers or excessive distortion of the amplifier. Status indicators Amplifier status can be confirmed with the indicator. [. . . ]
