6 Important safety information
Please read and strictly observe the following
instructions!
This user guide occasionally contains special highlighted notes. These vary as follows:
Note: Caution!!
Notes contain special information on
economical use
Notes marked with the word CAUTION or
the symbol draw your attention to
potential damage to equipment or the
environment.
The device contains an integrated class 1 laser
(CD drive). This is installed at an inaccessible
location in the device and does not constitute a
health hazard.
Do not take the car radio apart, make any modifications or attempt to repair it
yourself.
Never open the case of the car radio; it does not contain any serviceable parts! If the
case is open, there is a risk of fatality due to electric shock.
The car radio and the accompanying components should never be exposed to
dripping or splashing water. Make sure that no containers filled with liquid, such as
bottles or cups, are placed in the vicinity of the device.
Make sure that the display is not subjected to any knocks. These could damage the
display.
Make sure you are familiar with the different functions of your device before you start
driving. Excessively high volumes can pose a risk for you and other road users.
Therefore always set the volume to a level at which ambient noises (horns, sirens
etc) can still be heard.
Multimedia CDs also include data files in addition to audio files. If you play such a CD
in spite of the warnings, loud noises can occur at a volume level which can constitute
a traffic hazard. In addition, power amplifiers and speakers can also be damaged as
a result.
Do not use the car radio at an excessively high volume. This can damage your
hearing.
Only make any adjustments to the settings when your vehicle is parked. Your
concentration might otherwise be negatively affected by the changes.

6.1 Notes on operation/connection
Only connect the device to a 12V battery; the negative pole must be connected to
ground.
Do not switch on the radio for long periods of time if the vehicle engine is not running.
It has a comparatively high power consumption and can drain the battery to such a
low level that the engine cannot be started. Such a low charge also has a negative
effect on the life of the battery.
If you do not have sufficient knowledge to install the radio yourself, consult an expert.
Please note that any resulting costs will not be borne by JNC.
Before you install the device in the 1-DIN slot provided in the dashboard, take a look
at the wiring and make sure that all functions are in order.
Only use the accessories supplied with the device to ensure correct installation. The
use of parts which are not approved can cause malfunctions.
Please consult your car dealer if it is necessary to drill holes or make any other
modifications to your vehicle to install the device.
When installing the radio ensure that it does not impede the driver and cannot injure
passengers in the event of an accident.
This radio is designed for installation in vehicles with a 12V battery and with
connection of the negative pole to ground. Before installing the radio in RVs, trucks
or buses, always check the battery voltage.
Before starting installation work, disconnect the battery. This will prevent short
circuits.
When connecting the power amplifier and the other devices, comply with the
corresponding instructions in this user guide.
Secure the electric cables with clamps or adhesive tape. Protect cables laid on bare
metal surfaces by wrapping them in adhesive tape.
Lay and secure all cables so that they do not make contact with moving parts such
as the gear shift, hand brake or the rails of the seats.
Do not lay the cables at places which can become hot (e.g. heater outlets), as there
is the risk that the insulation could melt and cause a short circuit on the bodywork of
the vehicle.
Do not route the yellow wire of the battery connection into the engine compartment
through a drilled hole, as the insulation could be damaged and cause a dangerous
short circuit.
Do not shorten cables, as this could negatively affect the function of the protection
circuit.
Never tap the power supply by cutting into the insulation of the 12V connection cable
and connecting another consumer, as this would exceed the capacity of the cable
and cause overheating.
When replacing a fuse always ensure that it is replaced by a fuse of the same type
with the same specified amperage.

This radio may only be connected to high-performance speakers with a minimum
rating of 30 W and impedance ranging from 4 to 8 ohm. If speakers with a different
rating or impedance values are connected, the speakers can catch fire, start to
smoke or suffer damage.
When the power of this device is switched on, a control signal is output on the blue
wire. Connect this to the remote control connection of the external power amplifier or
the control relay of the car antenna (maximum of 300 mA 12 V). If the vehicle is
equipped with a screen antenna, this wire is connected to the supply terminal of the
antenna amplifier.
If the system is run with an external power amplifier, the blue wire should never be
connected to the supply terminal of the power amplifier. Also never connect the wire
to the supply terminal of the automatic antenna. Such a connection can cause
considerable power losses and malfunctions.
To prevent short circuits, all disconnected wires should always be wrapped with
insulation tape. In particular the supply cables of speakers which are not in use
should always be insulated with tape, as there is the risk of short circuits if the cables
are not insulated.
6.2 General information
Dirt or condensate on the lenses inside the device can prevent playback.
Never expose the device to direct sunlight, high dust concentrations, high
temperatures (above 60 °C) or a high air humidity (higher than 90 %). If the case
temperature is too high, cool the interior of the vehicle with the ventilation or air
conditioning system.
Do not switch the device on and off in quick succession. After switching the device
off, wait for at least 10 seconds before switching it on again.
Do not insert scratched, bent or broken CDs into the CD player. Never force a CD
into the device if it is not drawn in automatically.
6.3 Additional information
Playback of CDs which have been burned on a PC with the right format is generally
possible. It is, however, possible that the application software, the ambient settings or
other factors prevent playback (contact the software vendor for details.)
CD extra discs can be played back just like audio CDs.
Tracks recorded on CD-R/CD-RW discs (ID3TAG) and other text information
recorded on CD-R/CD-RW discs (ID3TAG) can be played back on this device.
If you play an CD-RW disc on this device, the time it takes for playback to start is
longer than for a conventional CD or a CD-R disc. Before using CD-R/CD-RW discs
always read the applicable operating instructions.
It is possible that not all functions are fully available when using some USB storage
devices.
