Switch on/off
Press the knob to switch on or turn off the radio.
Volume control
Turn the knob clockwise to increase volume. Volume control is electronic and does not have an end stop. If you have
a key pad in the steering wheel, increase or decrease the volume with the + or- buttons.
Volume control - ALARM
If a CD is playing when the radio receives an alarm bulletin (available in certain areas only), the CD player enters
pause mode. The bulletin is broadcast at the volume selected for this type of message.
After the bulletin has been completed, the audio system reverts to the originally selected sound source (radio or CD),
which is played at the volume that was selected for that source.
If the bulletin volume is adjusted while the bulletin is being broadcast, this new volume is saved and used for
subsequent bulletins.
Bass
Adjust the bass by pressing the button to extend the control and turning it to the left (less bass) or to the right (more
bass). A "detent" indicates "equalized" bass. Press the button back in when you have made the adjustment.
Treble
Adjust the treble by pressing the button to extend the control, pulling it out as far as possible, and then turning it to the
left (less treble) or to the right (more treble). A "detent" indicates "equalized" treble. Press the button back in when you
have made the adjustment.

This function is used to fine-tune the balance of sound in the speakers. To set the level:

Radio Broadcast Data System - RBDS
This feature, which may not be available in your area, functions only with FM broadcasts. The radio in your car is
equipped with an advanced system allowing information from broadcasters to be transmitted visually, as text, together
with the audio signal. This information is then decoded by the radio and made available for several new and unique
features.
The RBDS or Radio Broadcast Data System operates in the FM band only, and the information transmitted is supplied
exclusively by participating broadcasters. Volvo has no control over the accuracy of the data or information.
Coverage by local broadcasters may be limited at this time, but as the technology and benefits grow, you will find the
radio in your car is equipped to take advantage of this system.
PI (Program Information) Seek:
When an FM station has been stored as a preset, the radio also stores RBDS program information if it is available.
When the preset is selected at a later time, the radio tries to access updated program information. In weak signal areas,
there may be a delay before the station becomes audible. During this delay, "PI seek" will be displayed and there will
be no sound.
PI seek can be interrupted by pressing EXIT.
Radio text
Certain RBDS stations broadcast program information, which can be shown in the display. The text will be shown
twice in the display.
To start this function:
Press the FM button for several seconds.
To deactivate this function:
Press FM briefly.
Station information will be shown twice in the display.
Alarm
Alarms bulletins are transmitted automatically by certain RBDS stations. The function cannot be deactivated.
"Alarm!" is shown in the radio display when an alarm message is sent. The function is used to warn motorists of
