SAFETY FIRST
Before beginning installation, follow these simple rules:
1.
Be sure to carefully read and understand the instructions before starting installation of
your HMR-3.
2.
For best safety practices, disconnect the battery negative (-) terminal to prevent unintentional
damage to your HMR-3, electrical fire, and/or possible injury.
3.
For easiest installation, route all wires & cables prior to mounting your HMR-3.
4.
Route all RCA cables close together and away from high current wires.
5.
Use high quality connectors for reliable installation and to minimize signal or power loss.
6.
Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or
hydraulic lines, vacuum lines or electrical wiring when working on any vehicle.
7.
Never run wires underneath the vehicle. Running the wires inside the vehicle provides
the best protection.
8.
Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect
any wires routed through metal, especially firewalls.
9.
ALWAYS protect the battery and electrical system from damage with proper fusing. Install
the appropriate fuse & holder nearest the battery as possible.
10.
When grounding to the chassis of the vehicle, scrape all paint from the metal to ensure
a good, clean ground connection. Grounding connections should be as short as possible
and always be connected to metal that is welded to the main body, or chassis, of the
vehicle. Seatbelt bolts should never be used for connecting to ground.
