Hints and tips
Troubleshooting
Display says ‘No stations available’
Check that your aerial cable is uncoiled and ideally hanging
vertically. Press the Autotune button to search for services. Try
moving to another location to find better reception.
(?) Inactive or unavailable stations
Inactive or unavailable stations are those which appear on the
station list but are not available because either you are outside
the broadcast area, have lost reception or the station is not
currently broadcasting. Unavailable stations have a ‘?’ before
their name on the station list.
I can’t access secondary services
At the time of publishing not many secondary services are
available. If secondary services are available for the currently
selected station the secondary ‘>>’ indicator will be shown on
the display next to the station name.
Display says ‘Station not available’
This may occur if a broadcaster takes a station off-air whilst you are
listening to it. If tuned to a secondary service CHRONOS re-tunes
to the associated primary service. If tuned to a primary service,
CHRONOS waits until service resumes or you pick a new station.
I hear a ‘burbling’ sound on some stations
Although DAB is excellent at providing quality audio from very
little signal, the quality can suffer if the signal strength is too low.
If that happens, a ‘burbling’ sound can sometimes be heard.
Clock shows the wrong time
This may happen if the multiplex you last tuned to broadcasts an
incorrect time signal, try tuning to a station in another multiplex.

15
Resetting your CHRONOS
The reset option removes all presets, stored stations and favourite
station settings and resets all options to defaults. You may want to
use this option to restore default values.
1. Press and hold the Menu button for more than two seconds.
The display will ask ‘Press Select to confirm reset...’
2. Press the Select button to confirm the reset or press no
buttons for around seven seconds to cancel the reset.
