Cautions and Notes
Please read and follow the instructions and precautions in this installation guide when installing
DVM-100 and DVM-400 products.
• For assistance, a qualified installation technician or mechanic should be consulted.
• Do not use excessive force when removing the mirror from the windshield. The mirror
mounting plate may become separated from the windshield and/or the windshield may
break if excessive force is used. If you are unfamiliar with rearview mirror removal seek
professional assistance.
• Do not route wiring and cabling over sharp metal edges where they may become damaged
or cut.
• To prevent electrical shorts or breakage in the wiring and cabling, do not allow wiring and
cabling to be pinched behind trim pieces, panels, or other physical objects.
• Do not run wires or cables in areas where they may become damaged by heat from the
engine or the exhaust system.
• Do not install any DVM components or wiring in the deployment path of the air bag(s).
• When installing the cables or making wire connections, it is recommended you leave a little
‘slack’ in the cable connections to allow for service loops and for movement of the mirror so
the connections do not get pulled or accidentally disconnected.
• Where possible, avoid running cables parallel to other wiring and/or antenna coax that may
be installed in the vehicle.
• Where possible, do not leave excessive cable above the headliner.
• We recommend at least 2 feet of distance between our cabling and that of other systems
which may carry a signal for transmit and/or receive.
