LR3/Disco 3
CD (compact disc) Player
The CD (compact disc) player is a 6 disc in dash mounted device. The CD (compact disc) multi changer is capable of
playing commercial CD (compact disc) s, CD (compact disc) Rs, CD (compact disc) RWs and MP3 discs.
Random Play
The Random feature only works on the CD (compact disc) , which has been selected. The Random feature plays all the
tracks on the selected CD (compact disc) in a random order. All the tracks on that disc will be played before a new
random sequence is played. If a new CD (compact disc) is selected while in random mode, the random mode will be
cancelled and play will commence from track 1.
Repeat
The Repeat feature allows the current track to be repeated in an endless loop, when selected by the user.
MP3
The CD (compact disc) player has the capability to play MP3 files. The MP3 discs follow a format of folders and files
within the folder. It is also possible to place all the files in the root directory on the CD (compact disc) .
The random and repeat features follow the normal CD (compact disc) random and repeat feature functions.
Scan
Scan allows the user to play the first 10 seconds of each track on the CD (compact disc) s in the unit.
Automatic Volume Control-AVC
The AVC feature is designed to adjust output volume to compensate for the rising level noise of the vehicle as the vehicle
travels faster.
There are 10 settings for AVC, where 0 = off, 1 is the lowest setting (minimum volume change with speed and 9 the
maximum).
The vehicle speed signal is used to enable the IHU to calculate the volume adjustment required. The vehicle speed signal
is received over the CAN (controller area network) from the ABS (anti-lock brake system) control module. The signal is an
average of the four wheel speed sensor signals.
Control of the AVC is carried out by the audio amplifier.
Should an invalid speed signal be received the AVC will not alter the output volume.
CLOCK
The IHU contains the master clock functionality. The IHU contains and displays the clock in one unit. Other vehicle
modules that require clock functionality use the time supplied from the IHU.
The clock is available to any control module that is connected to an interconnecting bus i.e. either of the CAN (controller
area network) busses or the MOST ring.
The clock display configurable to show in AM/PM or 24 hour format. Midnight is shown as 12:00AM or 0:00 respectively.
The default condition, if not specified, after power on or delivery, should default to 1:00PM or 13:00. Depending upon the
market set the clock will default to either 12 or 24 hour format.
The time is adjusted from the IHU. This will ensure that all vehicle clocks will be synchronized at all times. Under
conditions when any bus could be asleep or shut down, the HMI does not allow clock adjustments.
