System Description [10/2019 - ]

1. A disc player uses a laser pickup to read digital signals recorded on a disc. By converting the digital signals to analog, it can play music, video and audio.
   WARNING:

   Do not look directly at the laser pickup because the disc player uses an invisible laser beam. Be sure to operate the player only as instructed.

   NOTE:

   • Do not disassemble any part of the disc player.
   • Do not apply oil to the disc player.
   • Do not insert anything but a disc into the disc player.
2. This player can play only audio CDs, CD-Rs (CD-Recordable) and CD-RWs (CD-ReWritable) that have any of the following marks:

4. Precautions for use of discs
   NOTE:

   • CD-Rs and CD-RWs may not be played depending on the recording conditions or characteristics of the discs, or due to damage, dirt or deterioration caused by leaving the discs in the cabin for a long time.
   • Unfinalized CD-Rs and CD-RWs cannot be played.
   • CD-Rs and CD-RWs are more easily affected by a hot and humid environment than discs used for normal audio CDs. For this reason, some CD-Rs and CD-RWs may not play.
   • If there are fingerprints or scratches on a disc, the disc may not play or the disc may skip.
   • Some CD-Rs and CD-RWs may deteriorate if they are left in the cabin for a long time.
   • Keep CD-Rs and CD-RWs in an opaque case.
   • SECAM color television standard discs cannot be played.
   • Keep the discs away from dirt. Be careful not to damage the discs or leave fingerprints on them.
   • Hold discs by the outer edge and center hole with the label side up.
   • Leaving the disc exposed halfway out of the slot for a long time after pressing the disc eject button may cause deformation of the disc, making the disc unusable.
   • If discs have adhesive tape, stickers, disc labels or any traces of such labels attached, the discs may not be ejected or player malfunctions may result.
   • Keep the discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.)
   • Do not use odd-shaped discs because these may cause player malfunctions.
   • Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected or played normally.
   • Use only 4.7 in. (12 cm) discs.
   • Do not use 3 in. (8 cm) CDs either with or without adaptors.

   HINT: 

   • When it is cold or raining, if the windows fog up, mist and condensation may form in the player. In such cases, the disc may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.
   • The disc may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.

      *a	FM (Stereo)
      *b	FM (Monaural)
      *c	AM

3. Radio reception problems

   HINT: 

   In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.

   1. Phasing

      AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter.

      Fig 6: Phasing

      Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      *a	Phasing
      *b	Ionosphere

   2. Multipath

      Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter.

      Fig 7: Multipath

      *a

      Multipath

   3. Fade out

      Fade out is caused by objects (buildings, mountains and other large obstructions) that deflect part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are less likely to be deflected.

      *a

      Fade Out

4. Noise problem

   Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems.

   Radio Frequency	Noise Occurrence Condition	Presumable Cause
   AM	Noise occurs in a specific area	Foreign noise
   	Noise occurs when listening to an intermittent broadcast	An identical program transmitted from multiple towers can cause noise where the signals overlap
   	Noise occurs only at night	Signal phasing
   FM	Noise occurs while driving in a specific area	Multipath resulting from a change in FM frequency

Information such as song names, broadcast station names, etc. can be received.
   NOTE:

   To receive audio-visual pay-type broadcasts, the customer must enter into a pay-type contract with Sirius XM Satellite Radio Inc. After entering into a contract, registration of the Radio ID is necessary. Also, if parts are replaced, the Radio ID must be re-registered.

   HINT: 

   When disconnecting the cable from the negative (-) battery terminal, the broadcast station logo data will be initialized. It takes a while for the broadcast station logo data to be updated to the latest one.

1. The Automatic Sound Levelizer (ASL) function automatically adjusts the audio system volume level in order to compensate for increased vehicle noise (vehicle noise tends to increase as vehicle speed increases). The ASL adjusts the volume level based upon vehicle speed signals that it receives from the combination meter assembly.
