Alpine MRV-F900 Owner's Manual page 13

4 Battery Lead (Sold Separately)
Be sure to add a fuse as close as possible to the MRV-F900's battery terminal. This fuse will
protect your vehicle's electrical system and the MRV-F900 in case of a short circuit. If you need
to extend this lead, the wire gauge should be AWG4 or larger.
NOTES:
• Please make sure not to short the exposed connector to any grounded metal surface when
replacing the fuse or making initial connection.
• When adding a fuse to the battery lead, be sure to use the 80A fuse (supplied) with its fuse
holder (supplied).
• Do not place the fuse holder (supplied) in the vehicle's engine compartment because of the
high temperatures reached in this area.
• In order to protect the vehicle's battery and the wiring, be sure to use an equivalent
replacement for the supplied (80A) fuse.
• The fuse holder (supplied) corresponds to an 80A fuse or lower. It is not suitable for a fuse
rated higher than 80A.
5 Ground Lead (Sold Separately)
Connect this lead securely to a clean, bare metal spot on the vehicle 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.
6 Remote Turn-On Lead (Blue/White, Sold Separately)
Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of
your head unit.
