Connecting speakers  
When connecting speakers connect the red (positive) terminals on DMX-50 to  
the red terminals on the speaker and black (negative) to black. The speaker  
cable has a darker tint on one strand to aid connection.  
Ensure that the bared ends of the wires are securely gripped by the spring  
clips. Note that the sound from new speakers should improve over the course  
of a few days as they are run-in.  
Switch on and off  
Before switching on for the first time - ensure the aerial is uncoiled and  
mounted as high as possible.  
DO NOT EXPOSE TO RAIN OR MOISTURE

ReVu™ - Pausing and rewinding radio  
ReVu mode lets you pause and rewind live DAB digital radio.  
DMX-50 constantly stores audio and text from the station you are tuned to in  
its memory. The amount stored depends on how long you have been listening  
to that station and the data rate of the broadcast. You can access this stored  
audio and pause or rewind live radio over short periods (approximately 10 to  
20 minutes depending on data rate).  
Once the memory is full, ReVu keeps adding to the memory but starts to  
overwrite the oldest stored audio and text.  
You can enter ReVu mode in two ways:  
0 9 : 4 0

To pause and replay live radio  
Press the ReVu button. The screen shows ‘Paused’ and the timer shows how  
far behind the live broadcast you are.  
Press the ReVu button again to start replaying the stored audio and text  
from where you left off. The timer stops counting, showing that you are now  
listening that many minutes and seconds behind real time. You can listen in  
this way for as long as you like, or press the fast forward, skip forward, stop  
button or press TUNE/SELECT to catch up to real time.

Using an SD memory card  
You can use an SD card in your DMX-50 for recording* and playing back DAB digital  
radio or playing MP2/ MP3 files recorded elsewhere.  
SD cards are readily available from PURE and other electronics retailers. As a rough  
guide – a 64 MB card will give you around an hour of recording time from a 128 kbps  
broadcast data rate.  
There is an ever increasing range of brands, capacities and quality of SD cards  
available. We have tested DMX-50 with the most popular cards but cannot guarantee  
all cards will work. Check www.pure.com/support for any known issues.  
Note DMX-50 records files to SD cards in MP2 format. You may need to use a  
computer to convert these files to a different format if you wish to use them in  
another device that uses SD cards. Check www.pure.com/support for information on  
software you can use to convert files.  
Inserting and removing a card  
To insert an SD memory card in your DMX-50 push the card label side up into  
the slot on the front panel with the gold pins towards the rear of the unit until  
it clicks.  
To remove a card push the card in slightly and it will pop out so you can  
remove it.  
It is not recommended that you remove a card when the SD access light is lit.  
Inserting an SD card  
Recording DAB radio  
You can record DAB radio* to SD card. The amount you can record depends  
on the size of your card and the quality of the audio being broadcast.

3. Press the RECORD button again to stop recording. You see a message  
giving the time, date and filename that the recording has been saved  
under. The filename is made up of the month, date and time. e.g.  
10141020.mp2 means that the recording was made on October the  
14th, starting at 10:20 am. The recording also stores the station and  
multiplex name. DAB recordings are saved in a special TRACKS folder on  
your SD card so they can be found easily.  
Recording in progress  
Tip If you have just missed the start of something you wanted to record try  
using ReVu to go back to where you want the recording to start then  
pressing RECORD. See pages 5 and 6 for more details on using ReVu.

Hints and tips  
(>>/ <<) 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, DMX-50 tries to tune to the  
station again and returns to the last station you were listening to if unsuccessful.  
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 fully extended. If the problem persists try  
moving your unit or repositioning your aerial using manual tuning.  
Screen says ‘No stations available’ in DAB mode  
Check that your aerial is fully extended. Use Autotune to search for stations. Use manual  
tuning to adjust your aerial position.  
Clock shows the wrong time  
This may happen if the last/current DAB multiplex or FM RDS station you tuned to  
broadcasts an incorrect time signal, try tuning to another station/different multiplex (DAB).  
Resetting your unit  
Resetting your DMX-50 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. The screen shows ‘Do you want to  
reset?.  
2. Push the ‘Yes’ shortcut button or use the  
+ Select button on the remote to  
confirm the reset or press no buttons to cancel the reset.  
My speakers don’t sound good  
Make sure that the red (positive) terminal on the speakers is connected to the red terminal  
on DMX-50 and black (negative) to black .  
Ensure the connections are secure and bared ends of the cables are contacting the metal of  
the terminals.  
Note that from new, the sound from your speakers should improve over the course of a few  
days as they are run-in.  
My screen is too bright in standby  
To set the brightness of your screen for when the unit is in standby press the MENU button,  
select Screen and choose Standby settings to alter the brightness or switch off the screen.  
Alarm bell icon has a cross through it  
This happens if you set an alarm but no DAB or FM RDS time has been acquired yet. Check  
that your aerial is extended, return to DAB/ FM or standby and wait for a short period and the  
normal icon should appear indicating that the time has been acquired.  
Screen says ‘Time not available’ or ‘Waiting for time...’  
This happens if time has not been acquired yet from a DAB signal or FM (RDS) signal. Check  
that your aerial is extended, switch to DAB, FM (RDS station) or standby mode, wait for a  
short period and the time should appear.
