Kia Forte: How vehicle audio works
AM and FM radio signals are broadcast from transmitter towers located around
your city. They are intercepted by the radio antenna on your vehicle. This signal
is then processed by the radio and sent to your vehicle speakers.
When a strong radio signal has reached your vehicle, the precise engineering
of your audio system ensures the best possible quality reproduction. However, in
some cases the signal coming to your vehicle may not be strong and clear.
This can be due to factors, such as the distance from the radio station, closeness
of other strong radio stations or the presence of buildings, bridges or other large
obstructions in the area.
AM broadcasts can be received at greater distances than FM broadcasts. This is
because AM radio waves are transmitted at low frequencies. These long distance,low
frequency radio waves can follow the curvature of the earth rather than travelling
straight. In addition, they curve around obstructions resulting in better signal
coverage.
FM broadcasts are transmitted at high frequencies and do not bend to follow the
earth's surface. Because of this, FM broadcasts generally begin to fade within short
distances from the station. short distances from the station. Also, FM signals are
easily affected by buildings, mountains, and obstructions. This can lead to undesirable
or unpleasant listening conditions which might lead you to believe a problem exists
with your radio. The following conditions are normal and do not indicate radio trouble:
- Fading - As your vehicle moves away from the radio station, the signal
will weaken and sound will begin to fade. When this occurs, we suggest that
you select another stronger station.
- Flutter/Static - Weak FM signals or large obstructions between the transmitter
and your radio can disturb the signal causing static or fluttering noises to
occur. Reducing the treble level may lessen this effect until the disturbance
clears.
- Station Swapping - As an FM signal weakens, another more powerful signal
near the same frequency may begin to play. This is because your radio is designed
to lock onto the clearest signal. If this occurs, select another station with
a stronger signal.
- Multi-Path Cancellation - Radio signals being received from several directions
can cause distortion or fluttering. This can be caused by a direct and reflected
signal from the same station, or by signals from two stations with close frequencies.
If this occurs, select another station until the condition has passed.
Using a cellular phone or a two-way radio
When a cellular phone is used inside the vehicle, noise may be produced from
the audio system. This does not mean that something is wrong with the audio equipment.
In such a case, try to operate mobile devices as far from the audio equipment as
possible.
CAUTION
When using a communication system such as a cellular phone or a radio set
inside the vehicle, a separate external antenna must be fitted. When a cellular
phone or a radio set is used with an internal antenna alone, it may interfere with
the vehicle's electrical system and adversely affect safe operation of the vehicle.
WARNING
Do not use a cellular phone while driving. Stop at a safe location to use
a cellular phone.
Caring for disc
- If the temperature inside the car is too high, open the car windows to
ventilate before using the system.
- It is illegal to copy and use MP3/WMA files without permission. Use CDs
that are created only by lawful means.
- Do not apply volatile agents, such as benzene and thinner, normal cleaners
and magnetic sprays made for analogue disc onto CDs.
- To prevent the disc surface from getting damaged, hold CDs by the edges
or the center hole only.
- Clean the disc surface with a piece of soft cloth before playback (wipe
it from the center to the outside edge).
- Do not damage the disc surface or attach pieces of sticky tape or paper.
- Make certain only CDs are inserted into the CD player (Do not insert more
than one CD at a time).
- Keep CDs in their cases after use to protect them from scratches or dirt.
Depending on the type of CDR/ CD-RW CDs, certain CDs may not operate normally
according to the manufacturing companies. In such circumstances, continued use may
cause malfunctions to your audio system.
✽ NOTICE - Playing an Incompatible Copy Protected Audio CD
Some copy protected CDs, which do not comply with international audio CD standards
(Red Book), may not play on your car audio. Please note that inabilities to properly
play a copy protected CD may indicate that the CD is defective, not the CD player.
NOTE:
Order of playing files (folders) :
Song playing order : to sequentially. Folder playing order :
❋ If no song file is contained in the folder, that folder is not displayed.
WARNING
- Do not stare at the screen while driving. Staring at the screen for
prolonged periods of time could lead to traffic accidents.
- Do not disassemble, assemble, or modify the audio system. Such acts
could result in accidents, fire, or electric shock.
- Using the phone while driving may lead to a lack of attention of traffic
conditions and increase the likelihood of accidents. Use the phone feature after
parking the vehicle.
- Heed caution not to spill water or introduce foreign objects into the
device. Such acts could lead to smoke, fire, or product malfunction.
- Please refrain from use if the screen is blank or no sound can be heard
as these signs may indicate product malfunction. Continued use in such conditions
could lead to accidents( fires, electric shock) or product malfunctions.
- Do not touch the antenna during thunder or lightening as such acts
may lead to lightning induced electric shock.
- Do not stop or park in parking- restricted areas to operate the product.
Such acts could lead to traffic accidents.
- Use the system with the vehicle ignition turned on. Prolonged use with
the ignition turned off could result in battery discharge.
CAUTION
- Operating the device while driving could lead to accidents due to a
lack of attention to external surroundings. First park the vehicle before operating
the device.
- Adjust the volume to levels that allow the driver to hear sounds from
outside of the vehicle. Driving in a state where external sounds cannot be heard
may lead to accidents.
- Pay attention to the volume setting when turning the device on. A sudden
output of extreme volume upon turning the device on could lead to hearing impairment.
(Adjust the volume to a suitable levels before turning off the device.)
- If you want to change the position of device installation, please inquire
with your place of purchase or service maintenance center.Technical expertise
is required to install or disassemble the device.
- Turn on the car ignition before using this device. Do not operate the
audio system for long periods of time with the ignition turned off as such operations
may lead to battery discharge.
- Do not subject the device to severe shock or impact. Direct pressure
onto the front side of the monitor may cause damage to the LCD or touch screen.
- When cleaning the device, make sure to turn off the device and use
a dry and smooth cloth. Never use tough materials, chemical cloths, or solvents
(alcohol, benzene, thinners, etc.) as such materials may damage the device panel
or cause color/quality deterioration
- Do not place beverages close to the audio system. Spilling beverages
may lead to system malfunction.
- In case of product malfunction, please contact your place of purchase
or After Service center.
- Placing the audio system within an electromagnetic environment may
result in noise interference.
- Prevent caustic solutions such as perfume and cosmetic oil from contacting
the dashboard because they may cause damage or discoloration.
