fully before you install the unit.
Damages caused due to an inapprop-
riate installation will not be covered by
warranty.
If you do not want to risk your warranty
entitlement, please let the technician
install the unit in your vehicle.
»To avoid a short circuit please
disconnect the vehicle battery before
the installation. To do it properly please
read the manual of your vehicle.
»Make sure that your vehicle is
equipped with a car radio slot of
required size (1DIN)
»As may be the case you will need a
suitable faceplate, adapter or other
accessories. These could be provided
from your local specialist supplier.
!
»The connection cables may not be
cutted or short-circuited. Otherwise the
warranty becomes invalid.
»Before the installation please make
sure that your vehicle has the 12 Volt
on-board power supply.
»The minus (-) should be connected
with the ground (GND) (negative).
»Please tag the polarity of the avai-
lable speakers before you disconnect
the vehicle battery.
»A proper grounding of the unit's
housing requires a clean ground
connection. Thus the grounding area
should be rust-, stain- and dust-free.
»Please ground the cable separately
from other heavy current devices such
as an amplier etc.
»Please ensure that the colored cables
are connected according to the wiring
diagram. The wrong wiring may lead to
malfunctions or even damages of the
electric elements of the vehicle.
»Please note that the connection
cables of this unit and of the other
devices may have the same purpose
but the different color. For this reason
while connecting this unit with the
other devices please ensure that both

combine this unit with devices that are
designed and construed for connection
with 2 speakers.
»The speakers should feature the
impedance of 4-8 Ohm and a sufcient
wattage.
»Please ensure that the speakers you
are connecting with the unit are intact.
Damaged speakers can impair the unit.
»To avoid a short circuit please isolate
all cable junctions and endings of the

wise the unit will not turn off automati-
cally, causing the discharging of the
vehicle battery.
»To avoid a rogue and hazardous
short circuit do not lay the yellow cable
through the engine bay in order to
connect it with the vehicle battery.
»Do not ever connect speaker cables
among one another. In case you do not
want to connect all the 4 speakers with
the unit please isolate the endings of
unused cables with the electrical tape
to prevent a short circuit.

Common solutions
Description of the
problem
Cause and solution
The remote control
is without function.
Solution 1:
Please ensure that the battery lm is removed. By delivery the
battery is protected by a lm which should be removed before
usage.
Solution 2:
The battery could be empty. Please replace it if required.
Solution 3:
Please make sure that the infrared receiver (labelled with IR)
on the control panel is not blocked.
Note:
You can test the functionality of the remote control
as follows: please hold the IR transmitter towards a
camera (e.g. a cell phone camera) and press any button
on the remote control. If the remote control is operative
you can see the infrared signal on the display of the
used camera device.
Radio stations are
lost:
As soon as the unit
will be turned off all
the stored stations
and user's settings will
be lost.
This problem is caused due to a wrong connection of the ISO
cable.
Please interchange the cables for ignition plus and for steady
plus.
Caution:
If these wires have fuses, the latter should be interchanged as
well.
Common solutions
The following advices are generally valid and refer to diverse XOMAX models with
the similar characteristics. Please note that some articles may refer not to your
model exactly and may contain the describtion of features and functions that your
model does not support.

Common solutions
Poor radio recep-
tion:
The radio tuner nds
no broadcaster or the
reception is poor.
For problem-solving regarding the radio reception it is
important to know the type of the antenna of your vehicle.
Here are the possible solutions for each type of the antenna:
Type 1 – passive antenna:
We recommend you to substitude the existing antenna by the
larger and therefore more efcient one.
Shark n or rod antennas (under 5 cm) are denitely insuf-
cient.
Type 2 – active antenna:
The vehicle provides no current for the active antenna. In this
case a phantom power is required, which provides the active
antenna with the external power supply.
Type 3 – active antenna with diversity system:
The unit provides no current for the active antenna and has
no diversity support. For this type of antenna is required the
phantom power with an integrated diversity system.
Note:
A phantom power is not to be confused with an antenna
amplier, which is far less efcient.
The unit does not
turn on.
This problem is in most cases caused due to a wrong connec-
tion of the ISO cable.
Please review the pin assignments of the ISO plug and ISO
socket. Pay attention to the proper connection of the ignition-
and steady plus and correct the discrepancy if required.
Note:
Though the design of ISO port is standardized, it's pin
assigment is not and may vary. Thus in case of mismatch
of connections due to different pin assignments a simple
plug'n'play connection may lead to grievous errors.
