CAUTION: These controls are for tuning your system. Please consult your authorized Dealer for

 WARNING

This symbol means important instructions. 

Failure to heed them can result in serious injury or death.

 CAUTION

This symbol means important instructions. 

Failure to heed them can result in injury or property damages. 

 WARNING

• 

DO NOT OPERATE ANY FUNCTION THAT TAKES YOUR ATTENTION AWAY FROM SAFELY DRIVING 

YOUR VEHICLE.

 

Any function that requires your prolonged attention should only be performed after coming to a 

complete stop. Always stop the vehicle in a safe location before performing these functions. Failure to do so may result in 
an accident.

• 

KEEP THE VOLUME AT A LEVEL WHERE YOU CAN STILL HEAR OUTSIDE NOISES WHILE DRIVING.

Excessive volume levels that obscure sounds such as emergency vehicle sirens or road warning signals (train crossings, 
etc.) can be dangerous and may result in an accident. LISTENING AT LOUD VOLUME LEVELS IN A CAR MAY ALSO 
CAUSE HEARING DAMAGE.

• 

DO NOT DISASSEMBLE OR ALTER.

 Doing so may result in an accident, fire or electric shock.

• 

USE THIS PRODUCT FOR MOBILE 12V APPLICATIONS.

 Use for other than its designed application may 

result in fire, electric shock or other injury.

• 

USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES.

 Failure to do so may result in fire or 

electric shock.

• 

DO NOT BLOCK VENTS OR RADIATOR PANELS.

 Doing so may cause heat to build up inside and may result 

in fire.

• 

MAKE THE CORRECT CONNECTIONS.

 Failure to make the proper connections may result in fire or product 

damage.

• 

USE ONLY IN VEHICLES WITH A 12 VOLT NEGATIVE GROUND.

 (Check with your dealer if you are not sure.) 

Failure to do so may result in fire, etc.

• 

BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMINAL.

 Failure to do so 

may result in electric shock or injury due to electrical shorts.

• 

DO NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS.

 Arrange wiring and 

cables in compliance with the manual to prevent obstructions when driving. Cables or wiring that obstruct or 

hang up on places such as the steering wheel, gear lever, brake pedals, etc. can be extremely hazardous.

• 

DO NOT SPLICE INTO ELECTRICAL CABLES.

 Never cut away cable insulation to supply power to other 

equipment. Doing so will exceed the current carrying capacity of the wire and result in fire or electric shock.

• 

DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES.

 When drilling holes in the chassis for 

installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring.  

Failure to take such precautions may result in fire.

• 

DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND 

CONNECTIONS.

 Bolts or nuts used for the brake or steering systems (or any other safety-related system), or 

tanks should NEVER be used for installations or ground connections. Using such parts could disable control of 

the vehicle and cause fire etc.

• 

KEEP SMALL OBJECTS SUCH AS BOLTS OR SCREWS OUT OF THE REACH OF CHILDREN.

 Swallowing 

them may result in serious injury. If swallowed, consult a physician immediately.
