USING YOUR DAB500
TURNING THE TUNER ON AND OFF
Make sure all the relevant connections, as described earlier have been made. As a precaution, make sure the amplifier volume is turned down low.
Press the "Power" button on the front panel.
TUNING
When first switched on, the DAB500 will automatically scan for all available stations (unless your aerial is not connected properly or DAB reception is weak or unavailable in your area). The display says 'now tuning…' when this takes place. There are two types of auto tune:
Rapid - this scans frequencies in the UK channel allocation. This should take approximately 45 seconds.
Full - scans the full range of digital frequencies in Band III. This may take several minutes.
To undertake a rapid scan, press the "Auto Tune" button for roughly two seconds. For a full scan press the "Auto Tune" button for longer than two seconds. If you have pressed “Auto Tune” by mistake press a third time to cancel the operation.
If no stations are found after the auto tuning process, "no stations found" will be shown on the display. If this occurs check the connections and positioning of the aerial or with your local radio stations for coverage information (see later in this manual for more details).
SELECTING A SERVICE
One of the key advantages of digital tuners is the simplicity of tuning.
Rotate the large tune/enter dial on the front panel to scroll through the available stations. To select a broadcast simply press the tune/enter dial.
PRIMARY AND SECONDARY SERVICES
Some selected stations have a primary and secondary broadcast, for example BBC Radio 4 broadcasts cricket commentary on analogue Long Wave, whilst simultaneously maintaining its normal programming on FM. If a secondary service is available, the display will show a dotted arrow pointing to the right sitting next to station name.
To select the secondary service, turn the tune/enter dial to the right. When the secondary service is displayed press the tune/enter dial.
CHANGING THE DISPLAY MODE
The DAB500 has various display modes which lets you view the additional text data that accompanies digital broadcasts. To access the various data channels press the "Info" button as indicated below:
Default mode - Presents scrolling text service offered by the particular station.
Press once - Gives the Program Type, which describes the genre of station.
Press again - Displays the name of the multiplex on which current service is found. See the section 'An overview of Digital Audio Broadcasting (DAB)' later in this manual for further information.
Press again - Shows the time and date.
Press again - Displays technical information, such as the channel label and centre frequency.
Press again - Displays the audio signal data rate (in kilobytes per second) and mode (stereo or mono).
Press again - Shows the signal error rate, where zero is perfect. The number increases as the signal deteriorates.
Press again - Returns to scrolling text service.
