audio INFINITI M 2011 Repair Manual

accordance with the maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.
SERVICING CLIMATE CONTROL
The climate control system in your INFINITI is
charged with a refrigerant designed with the envi-
ronment in mind.This refrigerant will not harm the
earth’s ozone layer. However, special charging
equipment and lubricant are required when servic-
ing your INFINITI air conditioner. Using improper
refrigerants or lubricants will cause severe damage
to your climate control system. (See “CAPACITIES
AND RECOMMENDED FUEL/LUBRICANTS” in the “9.
Technical and consumer information” section for
climate control system refrigerant and lubricant
recommendations.)
Your INFINITI retailer will be able to service your
environmentally friendly climate control system.
WARNING
The system contains refrigerant under high pres-
sure. To avoid personal injury, any air condi-
tioner service should be done only by an experi-
enced technician with the proper equipment.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select button
to turn on the radio. If you listen to the radio
with the engine not running, the ignition switch
should be pushed to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the vehicle may
influence radio reception quality.
Radio reception :
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception.
However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle,
even when the finest equipment is used. These
characteristics are completely normal in a given reception area, and do not indicate any mal-
function in your INFINITI radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, ter-
rain, signal distance and interference from
other vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.

FM radio reception :
Range: FM range is normally limited to 25 to 30
miles (40 to 48 km), with monaural (single
station) FM having slightly more range than
stereo FM. External influences may sometimes
interfere with FM station reception even if the
FM station is within 25 miles (40 km). The
strength of the FM signal is directly related to
the distance between the transmitter and re-
ceiver. FM signals follow a line-of-sight path,
exhibiting many of the same characteristics as
light. For example they will reflect off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to
fade and/or drift.Static and flutter: During signal interference
from buildings, large hills or due to antenna
position, usually in conjunction with increased
distance from the station transmitter, static or
flutter can be heard. This can be reduced by
lowering the treble setting to reduce the treble
response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and re-
flected signals reach the receiver at the same
time. The signals may cancel each other, result-
ing in momentary flutter or loss of sound.
AM radio reception :
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics. AM signals are also sub-
ject to interference as they travel from transmit-
ter to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.Satellite radio reception :
When the satellite radio is used for the first time
or the battery has been replaced, the satellite
radio may not work properly. This is not a
malfunction. Wait more than 10 minutes with
the satellite radio ON and the vehicle outside of
any metal or large building for the satellite
radio to receive all of the necessary data.
The satellite radio mode requires an active XM
Satellite Radio subscription. The satellite radio
is not available in Alaska, Hawaii and Guam.
The satellite radio performance may be affected
if cargo carried on the roof blocks the satellite
radio signal.
If possible, do not put cargo near the satellite
antenna.
A build up of ice on the satellite radio antenna
can affect satellite radio performance. Remove
the ice to restore satellite radio reception.

Compressed Audio Files (MP3/WMA/
AAC)
Explanation of terms :
● MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well known compressed digital audio
file format. This format allows for near “CD
quality” sound, but at a fraction of the size
of normal audio files. MP3 conversion of an
audio track can reduce the file size by
approximately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually no
perceptible loss in quality. The compression
reduces certain parts of sound that seem
inaudible to most people. ●
WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft as an alternative to MP3. The WMA
codec offers greater file compression than
the MP3 codec, enabling storage of more
digital audio tracks in the same amount of
space when compared to MP3s at the same
level of quality.
● AAC/M4A — Advanced Audio Coding (AAC) is
a lossy audio compression format. Audio
files that have been encoded with AAC are
generally smaller in size and deliver a higher
quality of sound than MP3.
● Bit rate — Bit rate denotes the number of
bits per second used by a digital music file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file.
● Sampling frequency — Sampling frequency
is the rate at which the samples of a signal
are converted from analog to digital (A/D
conversion) per second.
● Multisession — Multisession is one of the
methods for writing data to media. Writing
data once to the media is called a single
session, and writing more than once is
called a multisession.
● ID3/WMA Tag — The ID3/WMA tag is the part
of the encoded MP3 or WMA file that con-

Playback order :
●The folder names of folders not containing
compressed audio files are not shown in the
display.
● If there is a file in the top level of a disc/USB,
“Root Folder” is displayed. ●
The playback order is the order in which the
files were written by the writing software, so
the files might not play in the desired order.

Troubleshooting guide :
SymptomCause and Countermeasure
Cannot play Check if the disc or USB device was inserted correctly.
Check if the disc is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) be-
fore using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal temperature.
If there is a mixture of music CD files (CD-DA data) and compressed audio files on a CD, only the music CD files (CD-DA
data) will be played.
Files with extensions other than “.MP3 (.mp3)”, “.WMA (.wma)”, “.AAC (.aac)”, “.M4A (.m4a)”, or “.AA3 (.aa3)” cannot
be played. In addition, the character codes and number of characters for folder names and file names should be in
compliance with the specifications.
Check if the disc or the file is generated in an irregular format. This may occur depending on the variation or the set-
ting of compressed audio writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the disc or USB device is protected by copyright.
Poor sound quality Check if the disc is scratched or dirty.
It takes a relatively long time
before the music starts playing. If there are many folder or file levels on the disc or USB device, some time may be required before the music starts
playing.
Music cuts off or skips The writing software and hardware combination might not match, or the writing speed, writing depth, writing width,
etc., might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next
song when playing. If an unsupported compressed audio file has been given a supported extension like .MP3, or when play is prohibited
by copyright protection, the player will skip to the next song.
