Important safeguards
Read carefully through this manual to familiarize yourself with this high-quality sound system.
The beginning of operation is the moment of the unit installation. Before use the device in winter it is
recommended to heat up the passenger compartment during 20 seconds or to the operation temperature.
Use the unit with the temperature that goes beyond the operation temperature greatly decreases the
operation resource of the screen and other components of device and can result an outage.
Disconnect the vehicle's negative battery terminal while mounting and connecting the unit.
When replacing the fuse, be sure to use one with an identical amperage rating. Using a fuse with a higher
amperage rating may cause serious damage to the unit.
Make sure that pins or other foreign objects do not get inside the unit; they may cause malfunctions, or
create safety hazards such as electrical shock.
Do not use the unit in places where it can be exposed to water, moisture and dust.
Do not open covers and do not repair yourself. Consult the dealer or an experienced technician for help.
Make sure you disconnect the power supply and aerial if you will not be using the system for a long period
or during a thunderstorm.
Make sure you disconnect the power supply if the system appears to be working incorrectly, is making an
unusual sound, has a strange smell, has smoke emitting from it or liquids have got inside it. Have a
qualified technician check the system.
The unit is designed for negative terminal of the battery, which is connected to the vehicle metal. Please
confirm it before installation.
Do not allow the speaker wires to be shorted together when the unit is switched on. Otherwise it may
overload or burn out the power amplifier.

Connection diagram
Notes:
In spite of having any kinds of speaker system, must use 4 ohms impedance of speaker to reduce the
distortion during high volume level.
It is prohibited making the conductors of auto antenna and ground touch with each other.

Using the ISO Connector
1. If your car is equipped with the ISO connector, then connect the ISO connectors as
illustrated.
2. For connections without the ISO connectors, check the wiring in the vehicle carefully
before connecting, incorrect connection may cause serious damage to this unit.
Cut the connector, connect the colored leads of the power cord to the car battery as
shown in the table below for speaker and power cable connections.
