Operating Tips for Audio System

Do not spill any liquid on the audio

system.

●To prevent the battery from being discharged, do not leave the audio system

on for a long period of time when the engine is not running.

●If a cellular phone or CB radio is used in or near the vehicle, it could cause

noise to occur from the audio system, however, this does not indicate that

the system has been damaged.

WARNING

■Always adjust the audio while the vehicle is stopped

Do not adjust the audio control switches while driving the vehicle. Adjusting

the audio while driving the vehicle is dangerous as it could distract your

attention from the vehicle operation which could lead to a serious accident.

Even if the audio control switches are equipped on the steering wheel, learn

to use the switches without looking down at them so that you can keep your

maximum attention on the road while driving the vehicle.

NOTICE

For the purposes of safe driving, adjust the audio volume to a level that

allows you to hear sounds outside of the vehicle including car horns and

particularly emergency vehicle sirens.

Radio Reception

4-2. Audio System

■ AM characteristics

AM signals bend around such things as buildings or mountains and

bounce off the ionosphere.

Therefore, they can reach longer distances than FM signals.

Because of this, 2 stations may sometimes be picked up on the

same frequency at the same time.

Station 1

Station 2

■ FM characteristics

An FM broadcast range is usually about 25 - 30 miles (40 - 50 km)

from the source. Because of extra coding needed to break the

sound into 2 channels, stereo FM has even less range than monau-

ral (non-stereo) FM.

4-2. Audio System

Signals from an FM transmitter are similar to beams of light

because they do not bend around corners, but they do reflect.

Unlike AM signals, FM signals cannot travel beyond the horizon.

Therefore, FM stations cannot be received at the great distances

possible with AM reception.

Obstruction

Atmospheric conditions can also affect FM reception. High humidity

will cause poor reception. However, cloudy days may provide better

reception than clear days.

4-2. Audio System

● Multipath noise

Since FM signals can be reflected by obstructions, it is possible

to receive both the direct signal and the reflected signal at the

same time. This causes a slight delay in reception and may be

heard as a broken sound or a distortion. This problem may also

be encountered when in close proximity to the transmitter.

Reflected wave

● Flutter/Skip noise

Signals from an FM transmit-

ter move in straight lines and

become weak in valleys

between tall buildings, moun-

tains, and other obstacles.

When

a

vehicle passes

through such an area, the

reception conditions may

change suddenly, resulting in

annoying noise.

● Weak signal noise

In suburban areas, broadcast

signals

become

weak

because of distance from the

transmitter. Reception in

such fringe areas is charac-

terized by sound breakup.

YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)

277

4-2. Audio System

● Strong signal noise

This occurs very close to a

transmitter tower. The broad-

cast signals are extremely

strong, so the result is noise

and sound breakup at the

radio receiver.

● Station drift noise

When a vehicle reaches the area of 2 strong stations broadcast-

ing at similar frequencies, the original station may be temporarily

lost and the second station picked up. At this time there will be

some noise from this disturbance.

Operating Tips for MP3

MP3 stands for MPEG Audio Layer 3, which is standardized voice

compression established by the ISO*¹working group (MPEG).

Use of MP3 allows for audio data to be compressed to approximately

a tenth of the source data size.

This unit plays files with the extension (.mp3) as MP3 files.

*¹: International Organization for Standardization

• When naming an MP3 file, be sure to add an MP3 file extension

(.mp3) after the file name.

• The number of characters which can be displayed is restricted.

NOTICE

Do not use an audio file extension on files other than audio files. In addition,

do not change the audio file extension. Otherwise, the unit will not recog-

nize the file correctly resulting in noise or a malfunction.

Operating Tips for WMA

WMA is short for Windows Media Audio and is the audio compression

format used by Microsoft.

Audio data can be created and stored at a higher compression ratio

than MP3.

This unit plays files with the extension (.wma) as WMA files.

*: Microsoft and Windows Media are registered trademarks of Microsoft Cor-

poration U.S. in the United States and other countries.

• WMA files written under specifications other than the indicated

specification may not play normally or files or folder names may not

display correctly.

• The file extension may not be provided depending on the computer

operating system, version, software, or settings. In this case, add

the file extension “.wma” to the end of the file name, and then write

it to the memory.

NOTICE

Do not use an audio file extension on files other than audio files. In addition,

do not change the audio file extension. Otherwise, the unit will not recog-

nize the file correctly resulting in noise or a malfunction.

Operating Tips for AAC

AAC stands for Advanced Audio Coding, which is standardized voice

compression established by the ISO*¹working group (MPEG). Audio

data can be created and stored at a higher compression ratio than

MP3.

This unit plays files with the extensions (.aac/.m4a/.wav) as the AAC

files.

• AAC files written under specifications other than the indicated spec-

ification may not play normally or files or folder names may not dis-

play correctly.

• The file extension may not be provided depending on the computer

operating system, version, software, or settings. In this case, add

the file extension “.aac”, “.m4a”, or “.wav” to the end of the file

name, and then write it to the memory.
