The radio features anti-theft circuitry. If the set is removed from the vehicle or if the battery power is disconnected, a special code must be entered to enable operation of the set.
Refer to the radio code card supplied with your vehicle or ask your retailer for the correct code.
When the car is parked with the ignition key removed, the anti-theft LED will flash.
After installation or when power has been disconnected, `CODE' appears in the display when the set is switched on.
Enter the 4-digit code using the preset buttons. If the correct code is entered, the set is ready to use.
If you enter an incorrect code, you must enter the correct code again from the beginning.
If an incorrect code has been entered, `CODE Repeat' is displayed. Enter the correct code. After three unsuccessful coding attempts, the set will lock and remain locked for two hours. `System Off' appears in the display.
During this waiting period:
· the battery must be connected
· the ignition key must be turned to position I
· the unit must be turned on
Make sure the headlights are turned off to help prevent battery drain (please refer to
page 24
for information on turning the headlights off).
Enter the correct code after the two hours have elapsed.
Press the button to switch the radio on/off.
Turn this knob clockwise to increase the volume. The volume control is electronic and has no stop point.
Press the "FM" or "AM" button to select the waveband you require. The name of the station and the waveband will appear in the display.
NOTE: There are three FM bands and one AM band. This allows you to store 3 x 6 FM stations and 6 AM stations. By pressing the FM button repeatedly you can switch between FM 1, FM 2 and FM 3.
Turn this knob clockwise to select higher frequencies and counterclockwise for
lower frequencies. Stored frequencies appear in
the display.
Please note that this function will not interfere with pre-stored stations on buttons 1-6.
This function automatically seeks and stores up to 10 strong AM or FM stations in a separate memory. This is especially useful when travelling in areas where radio stations are unfamiliar.
1. Press and hold the `AUTO' button for at least one second. A number of strong stations (max. 10) on the chosen waveband are now automatically stored in the memory. An `A' now appears to the right in the display. If there are no sufficiently strong signals, `No Station' is displayed.
2. Press the `AUTO' button (for less than one second) if you want to change to one of the other auto-stored stations. A new auto-stored station will be selected each time the button is pressed.
1. Tune to the desired frequency.
2. Press a preset button (the audio will cut out) and keep it pressed until the audio comes on again (approximately two seconds).
3. The frequency is now stored on this preset button.
To select a preprogramed radio program, press the appropriate preset button. The stored
program will appear in the display.
Adjust the bass by pressing the button to extend the control and then 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 set the level.
Adjust the treble by pressing the button to extend the control 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 set the level.
Adjust front/rear speaker balance by pressing the button to extend the control and then turning it to the left (more sound from the front speakers) or to the right (more sound from the rear speakers). A "detent" indicates "equalized" balance. Press the button back in when you have set the level.
Pull out the `volume' button and turn clockwise/counterclockwise to adjust the
balance between the right/left speakers. The balance
is shown in the display.
The SC-901 radio is equipped with an advanced system allowing information from broadcasters to be transmitted inaudibly together with the audio signal. This information is then decoded by the SC-901 and made available for several new and unique features. The RDS or Radio Data System operates in the FM band only, and the information transmitted is supplied by participating broadcasters. Volvo has no control over the accuracy of the data or information. Please refer to pages 172-177 regarding specific descriptions and operation of these functions.
Volvo was among the first to pioneer this technology throughout Europe and it is slowly making its way to North America. Coverage by local broadcasters may be limited at this time, but as the technology and benefits grow, you will find the SC-901 radio ready to take advantage of this system.
This feature may not apply in your area.
If you tune into a station using RDS, the frequency is displayed followed by the name of the station in letters. The AF function ensures that the radio automatically tunes into the most powerful transmitter for the selected program.
Keep the FM button pressed down for at least two seconds. `AF Switch OFF' appears in the display for two seconds. If you want to switch on the AF function, press the FM button for less than one second. `AF Switch ON' then appears in the display.
`AF Switch ON'- Automatic station tracking is activated
`AF Switch OFF'- Automatic station tracking is deactivated
Press the left side of the station seek button to seek for lower frequencies and the right side for higher frequencies. The radio seeks the next audible station and stops there. Press the button again to continue searching.
If the TP button is depressed, the station seek function will only seek stations which broadcast this particular type of program.
Press the button to switch off this function.
Press this button to listen to each station for
8 seconds. If the unit is in tape or CD mode, each track will play for ten seconds.
This feature may not apply in your area and only functions with FM broadcasts. Please refer to the RDS information on page 172.
By pressing the TP button, RDS stations broadcasting traffic information can be heard. `TP' is displayed when this function is switched on. If the unit is in tape or CD mode when the radio receives traffic information, the respective function will be interrupted and the announcement is received at the volume selected for traffic information.
As soon as the announcement is over, the previous volume will be restored and the tape or CD will start to play again.
· Traffic information can only be received when TP is displayed.
· If TP is flashing, it means that either no
traffic information is being broadcast by
the current transmitter or the signal is
too weak.
After approximately 70 seconds, an audible signal will be heard, indicating that
you should change to a stronger TP transmitter. To turn off this signal:
- Turn the radio off
- Press and hold down the TP button and turn the radio on. By pressing the TP button again, you can turn the TP alarm on or off.
The radio will function normally again after 5 seconds.
· Press the TP again if you want to
stop listening to a traffic announcement.
This feature may not apply in your area and only functions with FM broadcasts. Please refer to the RDS information on page 172.
Press the NEWS button to seek a station broadcasting news programs.
