    pg. 134 Radio - general functions

    Auto storing radio stations (14)

    This function seeks and stores up to 10 strong AM or FM stations in a separate memory. The function is especially useful in areas where you are not familiar with the radio stations.

  • Press the AUTO button (2). A number of stations with strong signals (maximum 10) from the selected FM or AM band can be stored automatically in the memory.
  • AUTO is displayed and the stations found will be indicated as A1-A0, where 0=10.

    If, for example, there are only 5 strong stations in the area, only A1-A5 will be stored in the memory

    If no stations with sufficient signal strength are found, NO STATION will be displayed.

    Since Auto Store stores stations that have been found in a temporary memory, these stations will be erased from the memory when the audio unit is switched off. When the unit is switched on again, the radio will search for and store up to ten new stations.

    If Auto Store finds a station that you would like to store in the system's permanent memory, please refer to point 2 in the next section.

    To restart the auto store function, press the AUTO button for more than 2 seconds.

    2. Press the PRESET knob (14) briefly. Select a number by turning clockwise/counterclockwise. Choose between AM 1-10 or FM 1-20.

    Press this button again briefly to store the desired frequency/station.

    Using preset stations (14)

    To tune to a pre-selected radio station, turn PRESET (14) to the stored number: AM 1-10 or FM 1-20.

    The selected station will be displayed with its number under the text PRESET.

    The following settings can be adjusted in the

    AUDIO MENU:

  • BASS - Choose a setting between -6 and +6
  • MID - Choose a setting between -6 and +6
  • TREBLE - Choose a setting between -6 and +6

  • FADER - speakers front/rear
    Choose a setting between front 12 and rear 12
  • SET TO ALL "0" - sets all values for
    AUDIO alternatives to zero.

    The following settings can be adjusted under OTHER Settings (default settings are underlined):

  • NEWS - ON/OFF
  • PTY - ON/OFF
  • PTY Settings (only when PTY is ON)
    1. Choose among the alternatives displayed.
    2. BACK: exits the OTHER Settings menu and saves settings that have been made.
  • TP Station - push the menu knob to set the current station as favorite TP station.

    NOTE: If no stations are available, this menu alternative will be skipped.

  • NEWS Station - press the menu knob to set the current station as the selected NEWS station.

    SETTINGS - the following 10 settings can be made (default settings are underlined):

    1. AF ON/OFF (Automatic Frequency update) - the AF function ensures that the strongest available transmitter for a program is selected.

    2. REG LOCK/SWITCH (Regional radio program) - a local radio station can broadcast on several frequencies and it can broadcast the same or different programs at the same time on different frequencies. If the same program is transmitted, then the SWITCH setting is preferable for the best reception while driving. If each frequency (of the same local radio station) has its own program then the LOCK setting is preferable to enable the radio lock on the current frequency. In this situation, if SWITCH is selected, the radio will select the frequency with the best audio sound, which results in the radio switching between different local programs.

    4. ASC LOW/MID/HIGH
    5. SRC ON/OFF

  • SET TO DEFAULT - this alternative sets all RADIO settings to their default values.

    pg. 142 RDS

    Radio Data System
    The Volvo HU-555 is designed for the digital information system RDS (Radio Data System).
    RDS features automatic programming and instant traffic information and it broadens the possibilities for program choices. The transmitter broadcasts information about the program. This information is represented by a data code, which identifies the program, irrespective of which frequency the information is transmitted.

    This means that the driver does not have to change the frequency if he wants to continue listening to the same program. Every station/program has a specific identification which the radio searches for.

    The RDS radio can also receive traffic information. This is transmitted with a special signal which cuts through any normal radio transmission, or CD play back and is always heard at its own adjustable volume.

    PTY (Program Type) information, which is an extension of the RDS system, is also transmitted in certain areas.
    There are a number of other features in the RDS-system, such as time control signals, alarms etc.

    pg. 143 Compact disc care

    Compact disc care

  • Before using a new disc for the first time, remove any burrs in the center/outer edge by running the stem of a pen or similar object around the hole/edge of the disc.
  • Use high quality discs only.
  • Keep the discs clean. Wipe them with a soft, clean, lint-free cloth, working from the center outwards. If necessary, dampen the cloth with a neutral soap solution. Dry thoroughly before using.
  • Never use cleaning spray or anti-static liquid. Use only cleaners specifically made for CD's.
  • Use discs of the correct size only

    NOTE: Never use 3.5" discs.

  • Do not put tape or labels on the disc itself.
  • Volvo does not recommend the use of plastic outer rings on the disc.
  • Condensation may occur on discs/optical components of the changer in cold winter weather. The disc can be dried with a clean, lint-free cloth. Optical components in the CD changer may, however, take up to one hour to dry off.
  • Never attempt to play a disc which is damaged in any way.
  • When not in use, the discs should be stored in their covers. Avoid storing discs in excessive heat, direct sunlight or dusty locations.
