Secure the wiring with zip ties or electrical tape. . To protect the wiring, wrap 

adhesive tape around them where they lie against metal parts. To avoid 

short-circuiting, cover all disconnected lead with insulating tape. There is a 

possibility of short-circuiting if the leads are not insulated.

Route and secure all wiring so it cannot touch any moving parts, such as the 

gear lever and handbrake. Do not route wiring in places that get hot, such as 

near the heater outlet. If the insulation of the wiring melts or gets torn, there is 

a danger of the wiring short circuiting to the vehicle’s body.

Don’t pass the yellow lead through a hole into the engine compartment  to 

connect to the battery. This will damage the lead’s insulation and cause a very 

dangerous short. 

Do not shorten any leads, if you do, the protection circuit may fail to work 

when it should. 

Never feed power to other equipment by cutting the insulation of the power 

supply lead of the unit and tapping into the lead. The current capacity of the 

lead will be exceeded, causing overheating. 

Since a unique audio I/C circuit is employed, never wire so the speaker leads 

are directly grounded or the left and right - speaker leads are common. 

When this product’s source is switched ON, a control signal is turned on 

through the Blue/White lead. Connect to an external power amp’s system 

remote control or the car’s Auto-antenna relay control terminal (max. 500mA 

12V DC). 

Do not block any vents or heater panels, Blocking them will cause heat to build 

up and may result in fire. 

When replacing the fuse(s) the replacement must be of the same amperage 

as shown on the fuse holder. Never replace a fuse with another of a different 

value. If the fuse blows again please contact your instsallation company. 

Double check that all wiring and connections are correct before re-connecting 

the battery and turning on the unit.

After completing the installation and before operating the unit, reconnect the 

battery, then press the (RES) button with a pointed object, such as a ball-point 

pen to set to unit to it’s initial status. After pushing the button, wait a few sec-

onds for the red light to flash.
