Warnings Before Installation

Important Warnings to Take Note of BEFORE Com­mencing Installation

Damage Caused By Incorrect Installation or Usage is
NOT Covered By Warranty. PLEASE Take The Time To
Read The Installation Notes Carefully.

• To avoid shorts in your vehicles electrical system, be
sure to disconnect the battery cable before beginning in­stallation.

• This unit is intended for vehicles with a 12-volt battery and
negative grounding. Before installing the unit in a recreational
vehicle, truck, or bus, check that the battery voltage is 12 volts.

• Remove the two transport screws from the top of the unit

before installation.

• The black lead is ground. A good chassis ground requires a
tight connection to ground. The area should be free from rust,
paint or any form of dirt. Please ground this lead separately
from the ground of high-current products such as power amps.
If you ground the products together and the ground becomes
detached, there is a risk of damage to the products or fire.

• Be sure to connect the colour coded leads according to the di­agram. Incorrect connections may cause the unit to malfunction
or damage the vehicle’s electrical system. Cords for this prod­uct and those for other products may be different colours even
if they have the same function. When connecting this product
to another product, refer to the supplied installation manuals of
both products and connect cords that have the same function.

• Be sure to connect the negative (-) speaker leads to the nega­tive (-) speaker terminal. Never connect the negative (-) speak­er leads to chassis ground.

• The unit is only designed for use with 4 speakers. Do not
combine outputs for use with 2 speakers. Do not ground nega­tive speaker leads to the chassis ground.

• Speakers connected to this unit must be high-power units with
a minimum rating of 45W and impedance of 4 to 8 ohms. Con­necting speakers with output and/or impedance values other
than those noted here will result in damage to the head unit and
the speakers. Check the condition of your speakers carefully­connecting this unit to old or degraded speakers may result in
a fault which will damage the audio IC and invalidate the war­ranty.

Warnings Before Installation

• If this unit is installed in a vehicle that does not have an ACC
(accessory) position on the ignition switch, the red lead of the
unit should be connected to a terminal coupled with ignition
switch ON/Off operations. If this is not done, the vehicle battery
may be drained when you are away from the vehicle for several
hours.

• Secure the wiring with cable clamps or adhesive 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.

• When this product’s source is switched ON, a control signal
is outputted through the orange lead. Connect to an external
power amp’s system remote control or the car’s Auto-antenna
relay control terminal (max. 300mA 12 V DC). If the car features
a glass antenna, connect to the antenna booster power supply
terminal.

• When an external power amp is being used with this system,
do not connect the orange lead to the amp’s power terminal.
Likewise, do not connect the orange lead to the power termi
of the auto-antenna. Such connection could cause excessive current
drain and a major malfunction. Refer to the relevant owner’s manual
for details on connecting the power amp and other units, then make the
connections correctly.

• Do not block any vents or heater panels. Blocking them will cause
heat to build up and may result in fire.

• Make sure that the unit has a good chassis ground. A good ground
connection will eliminate most electrical noise. A good chassis
ground requires a tight connection to the vehicles metal chassis.

nal

Warnings Before Installation

The area around the ground connection should be clean, bare metal

without rust, paint, plastic or dirt for a good electrical connection.

• If noise is still experienced when the motor of the vehicle acceler­ates, a choke should be placed in line with the power to the unit. The
installation company will know what is required.

• 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 installation company.

• Do not block vents or heater panels. Blocking them will cause heat
to build up inside and may result in fire.

• 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 the unit to its initial status. After push­ing the button, wait a few seconds for the red light to flash.
