Note. ID3 is a tagging format for MP3-formatted files. ID3 allows metadata (e.g., title, artist, track number) to be added to the MP3-formatted file. There are two versions in the ID tag. ID3v1: This is the most widespread standard tag format and most software is compatible with this version. There is a limitation on the maximum number of characters for the text data. ID3v2: There are a variety of versions in V2, but there is no interchangeability among the versions.

FOREWORD [RADIO]

Note. If the case location, time, and broadcasting station etc. can be specified through interview with the customer, there is the possibility that the signal reception environment is the cause of the problem. Perform confirmation of the symptom and evaluate under the conditions that the customer reported (location, time, broadcasting station etc.). If this is not possible, perform it under equivalent conditions. Before inspection or repair, record the broadcasting stations that customer has preset and reset them accordingly after the inspection or repair. Adjust the clock too.

RECEPTION FREQUENCY OF RADIO SLIPS POSSIBLE CAUSES

Stereo and Monaural Receptions

1. As signals become weak, noise may appear more in stereo reception. Compared to stereo reception, noise in monaural reception is relatively less apparent.

Separation Control

1. Utilizing the characteristic of monaural reception that noise is relatively less apparent than stereo reception, the audio system automatically changes the reception from stereo to monaural and lessens annoying noise when signals become weak or a multipath phenomenon occurs.

High Tone Control

1. When signals become weak or a multipath phenomenon occurs, the audio system restrains the volume level in the high frequency band and lessens the annoying noise.

Scheme 58

1. The separation and high tone controls influence sound quality, Therefore they are specifically tuned to the individual model. (Comparison of characteristic must be done on the same models)

Scheme 59

1. Signals tend to reach longer distances at night. This is particularly true for AM signals where foreign broadcasts or noise may cause inadvertent operation. Though the audio system restrains the sensitivity of the SEEK and SCAN functions at night, the audio system may select other than desired broadcasting stations other than those desired when signals are considerably strong. This function is linked to the parking light. When the parking light or the headlights are turned on, SEEK and SCAN may not function for weak signals.

Scheme 60

1. The CD player/changer has been designed to play CDs bearing the identification logo, COMPACT DISC DIGITAL AUDIO (Scheme 60) No other discs can be played on the CD player/changer other than MP3 applicable ones.
2. The CD player/changer may not play the following types of CDs: Defective CDs (e.g., cracked, badly bent, rough edges, scratch, dirty CD condensation) 8 cm (3 in) CD accessories (e.g., 8 cm (3 in) disc adapter, sticker, label) Nonstandard CDs (e.g., Diameter/thickness is out of specification) Specification: 119.7-120.3 mm (4.668-4.692 in) of diameter, 12+0.3 or -0.1 mm (0.047+0.012 or 0.004 in) of thickness
3. Do not use non-conventional discs. The CD player/changer could be damaged.

Scheme 61

1. Although the same physical size as the compact disc, SACDs use a different kind of digital audio signal called Direct Stream Digital.
2. The CD player/changer may not play the CD-R/RW properly due to the disc condition (excluding MP3).

Outline of CD-R and CD-RW

1. Definition CD-R: The CD-R is a non-rewritable version. Once a section of a CD-R is written, it cannot be erased or rewritten. CD-RW: The CD-RW is a re-writable version of CD-ROM and the data can be written an unlimited number of times. Since the reflected laser beam amount of a CD-R/RW is less than the reflected laser beam amount of the conventional CD media, the CD player/changer may not play the CD-R/RW or the sound may jump. Since the recording quality of the CD-R/RWs vary widely, some CD-R/RWs may not play.

Recording Method

1. There are two methods for recording.
2. Classification by recorder Record the audio data in the audio-CD by audio recorder The price of the audio recorder and original audio-CD include the copyright fee. Record the audio data to a conventional data-CD using a personal computer The data-CD is cheaper than the audio-CD. But, there are lower quality CDs.
3. Classification by audio data extraction/compression Extracted audio data The CD-R/RW player can play the extracted audio data. Compressed audio data It is possible to record a large quantity of music to a disc. The sound quality varies depending on the audio data compression format. The compressed audio data can be played on the applicable player only. Types of compression format: MP3: MPEG Audio Layer 3 - Mazda genuine MP3 applicable CD player is available. WMA: Windows Media Audio ATRAG: Adaptive Transform Acoustic Coding

MP3

1. The following conditions should be met in order to record the MP3-formatted data to the MP3 applicable CD player
