Hints and tipsTroubleshooting

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 stationsInactive 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 servicesAt 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 stationsAlthough 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 timeThis may happen if the multiplex you last tuned to broadcasts an incorrect time signal, try tuning to a station in another multiplex.

buttons for around seven seconds to cancel the reset.
