(>>/<<) DAB Secondary services
Secondary services accompany some stations, providing extra information or alternative
content and may only be broadcast at certain times. At the time of writing not many
secondary services are available. If a station has secondary services available, the station
shows ‘>>’ next to its name in the station list and the secondary service appears next to the
station in the list. A secondary service has a ‘<<’ before its name in the station list.
(?) Inactive or unavailable DAB stations
Inactive or unavailable stations are those which appear on the station list but are not
currently 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. If you select a station which has this symbol, DTM-300 will retry the
station and, if still unavailable, returns to the last station you were listening to.
I hear a ‘burbling’ sound on some DAB 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. To help reduce this, check that your aerial is mounted as high as possible and
the arms are fully extended vertically. If the problem persists try moving your radio or
repositioning your aerial using manual tuning.
Screen says ‘No stations available’ in DAB mode
Check that your aerial is connected and fully extended. Use Autotune to search for stations.
Use manual tuning to adjust your aerial or radio position.
Resetting your unit
Resetting your DTM-300 removes all presets, stored stations and favourite station settings
and resets all options to defaults. To reset:
1. Press and hold the Menu button for three seconds. You see ‘Press SELECT to confirm
reset’ on screen.
2. Press the SELECT button to confirm the reset or press no buttons to cancel the reset.
Clock shows the wrong time
There are three clock displays available on your DTM-300. The first is the built-in clock which
you view by pressing the TIME button on the remote. You set this clock using the Clock
settings > Set time menu option.
The second clock is broadcast by most DAB radio stations and the third by some FM (RDS)
stations. You can view these clocks by pressing the INFO button until the clock display is
shown on screen. These two clocks are controlled by the broadcasters and you cannot
adjust the time on these clocks.
