The brief was just a few simple words on a single sheet of paper
- yet the task was enormous: "Create the best sound in the world
regardless".
Two years after delivering the brief to our sound technicians, our
club sound-system was ready. Housed in a specially constructed
room simply referred to as 'The Box', it was the result of intensive
research across the globe, utilising specialists in all areas of
sound and electronics. Bass experts from the USA, high-
frequency boffins from Scandinavia and cabinet builders
previously agonising over Rolls Royce dashboards, all finally
came together with a host of other technicians, boffins and anoraks
to build what has now become a legend to dance music fans
across the globe.
Since then our sound-system's become an obsession - religiously
stripped down each week, the highly tuned system, likened to an
F1 racing car, gets constantly upgraded to retain its state-of-the-
art status. More recently the addition of digital processing means
sound can be thrown around the Box from all angles and tuned
to replicate a garage (well that's where it all started!) or a stadium.
But, above all, we've developed 'M-Bass' - unique digitally
processed algorithms delivering the absolute best, most
awesome low frequencies ever.

3
After 10 years of refinement, tweaking and pampering, and with
the advent of advanced chip technology, we can bring you your
very own 'M-Bass' - the true sound of The Box right in to your very
own home, or the palm of your hand.
So times may have changed, as has technology, but whether it's
for our club or audio products, the brief's as true today as it ever
was - "Create the best sound in the world regardless".

What is digital radio?
DAB (Digital Audio Broadcasting) is the next
generation of radio.
DAB was developed in Europe by a
consortium of broadcasters and
manufacturers.
DAB uses digital compression techniques
to transform the source material, i.e. music
and speech, into digital computer code
before it is transmitted. The computer code
consists of electronic “ones and zeros”
called binary digits or bits. The binary code
is then multiplexed or grouped together to
create a superior signal, when compared
with the older analogue system, with the
following key benefits:
•Near CD quality sound.
Because DAB is binary coded, the
receiving equipment is only expecting
to receive a series of ones and zeros,
so any other interference is ignored,
resulting in very high quality audio.
•Interference free reception.
Analogue systems suffer from an effect
called “multipath distortion”. This is
caused because radio waves do not
behave in an orderly fashion, but
bounce and reflect off buildings and
mountains etc. DAB sees this as an
advantage and uses the direct and
reflected signals to actually reinforce
the end result.
•No need to re-tune.
A single DAB frequency can be used
to cover the whole of the UK, so solving
many of the problems experienced
with the earlier analogue system.

Getting Started
Carefully remove your Ministry of Sound
MOSDR011 Digital Radio from the box. You
may wish to store the packaging for future
use.
Read these instructions before operating
the radio.
In the box
Inside the box you should find the following
items:
•The Digital Radio
•A set of DAB headphones
•Two size AA batteries
•The User Guide
If any items are missing call the Helpline
on 0870 010 5676.
Battery installation
Remove the battery compartment cover
clipped to the rear of the radio by sliding the
cover away from the nameplate using your
finger on the indentations below the
nameplate. The cover will become free
when it is slid back a few millimetres.
Place the two supplied batteries in the
compartment paying attention to the
polarity of the batteries. Orientate the
batteries as shown in the diagram above
noting that the two batteries face in opposite
directions in the compartment. The
negative end of each battery should make
contact with the large spring terminal in the
compartment.
If the batteries are inserted incorrectly, the
radio will not switch on. The design of the
terminals is such that incorrect orientation
of the batteries will result in them not being
connected to the radio, thereby protecting
the radio from damage.

The screen
The radio employs an STN transflective blue
backlit LCD screen. It has a row of fixed icons
across the top of the screen that indicate
user settings and provide information to the
user about the status of the radio.
Below the icons there is a two-line
alphanumeric display with sixteen
characters on each line that displays
information about the received stations.
The backlight allows the screen contents
to be easily viewed in dark ambient
conditions. The screen is backlit as follows:
•When the radio is switched on.
Backlighting remains on for 5 seconds.
•When the power key is pressed to turn
off the radio.
•At any key press.
Backlighting remains on for 3 seconds.
•When a suitable external power supply
(4.5V d.c.) is plugged into the power
supply socket on the radio, the
backlight is turned on and remains on
while the radio is powered externally.
Fixed Icons
Volume level indicator
You can set the volume level to any of
fourteen preset levels. The icon displays the
set level by displaying an increasing number
of bars (from 0-7) as the volume level is
increased. The volume level icon seen top
left corner of the LCD display illustrated on
this page shows the radio set to full volume.
The speaker symbol in the icon remains on
at all times.
Battery level indicator
The state of the batteries is indicated by the
battery icon. The number of bars (0 to 3)
indicate the power left in the battery. An
unused (new) battery should indicate three
bars as shown in the LCD screen shown on
this page. If only one bar is displayed, this
means that the power available is low.
No bars indicate that the batteries are very
low. When the power is too low for the radio
to operate, the icon will flash and the unit
will shut down automatically.

9
Time
The time is displayed in a 24-hour digital
format. The clock is only displayed when
DAB is being received. It shows the time
broadcast by the DAB stations.
Favourites/Heart
The heart-shaped ‘favourites’ icon is only
displayed when you have set the received
stations to list in the order of the most played
stations (your favourites).
Graphic Equaliser
The eq icon indicates the type of
equalisation you have chosen to apply to
the station playing. There are six different
settings to choose from. Note that the
equalisation setting can only be altered
when a station has been selected.
Signal strength
The signal strength icon provides an
indication of the signal strength of the
station currently playing. It is dynamic and
it changes as the signal strength changes.
The icon displays as one of four states that
indicate no minimum signal received
through to strong signal strength received.
Switching the radio on
•Check that the batteries have been
installed correctly.
•Ensure that the lock switch on the top
panel is set to the unlock position.
•Plug in the headphones into the jack
on the side of the radio as shown.
WARNING
DO NOT TURN ON THE RADIO WITH
THE HEADPHONES CONNECTED AND
THE EARPIECES INSERTED IN YOUR
EAR. LOUD SOUNDS CAN DAMAGE
YOUR HEARING.
The headphones also act as the aerial, so it
is important that they are plugged in prior
to switching on the radio or you will not be
able to find any stations.
Please note that this radio has only
been designed to operate with the
supplied headphones.

10
Press the power switch on the top panel.
The screen will light up and the line of icon
indicators will be seen, along with a
welcome message. After a short delay, the
message is replaced with other text as
described in the section entitled Using the
Radio. See page 16 for further details.
Battery level indicator
The battery level indicator icon should
appear as illustrated on page 8.
Headphones
Place the earpieces in your ears, checking
as you do so that the volume is not too loud.
Associated components which aid
reception are contained within the
headphone cable. In some instances this
cable will need to be repositioned to improve
the reception quality.
Switching the radio off
Press the power push-button switch on the
top panel and hold for about two seconds.
The screen will be backlit (blue) during this
period. Release the switch as the on screen
information is cleared. The radio is now off.
Locking the radio
The radio may be locked while the radio is
on or off. It is a good idea to lock the radio
while it is off so as to prevent it from being
turned on accidentally and resulting in the
batteries being run down.
The radio may be locked at times when you
are listening to a station so as not to allow
the settings to be accidentally changed,
when carried in a pocket for example.
Move the lock switch on the top of the radio
to the lock position indicated by the arrow
shown on the switch legend. To unlock the
radio at any time, slide this switch to the
unlock position.

11

When switched on, all functions of the radio
are controlled by the five push buttons on
the front panel.
From left to right these buttons are referred
to by their function as follows.
•info button
•preset button
•The Central Navigator button
(multifunction)
•eq button
•menu button
The operation of these buttons to tune in
and play the received digital audio stations
are described in Using the Radio starting on
page 16 of this guide.
Power adaptor
If desired, this radio may be powered from
the mains by means of a suitable mains
power adaptor. This item is not supplied, see
Technical Specifications for details.
When the DC jack is inserted, the radio is
momentarily turned off.
Rechargeable batteries
The radio may also be powered by Metal
Hydride rechargeable batteries. However
these only provide about half the playtime
from a full charge compared with the
playtime that new standard Duracell
batteries.
Please note that this radio will not
charge rechargeable batteries.
A separate charger intended for this
purpose is required.

Using the Radio
Introduction
The MOSDR011 is a portable digital radio. It
can be worn or carried in a pocket or bag to
receive and listen to digital radio. It runs from
2 x AA batteries providing enough battery
life for approximately 8 hours continuous
playtime.
The screen allows users to view the DAB
stations available, along with scrolling text
known as DLS and other settings/service
information associated with each station.
The radio uses a set of headphones that act
as the aerial and are specially designed to
receive DAB signals.
Control buttons
There are seven buttons on the radio. Their
functions are as described in the following
overview.
Power on/off
The power button is used to turn the radio
on and off. To turn on the radio, press and
hold the power button until the welcome
message starts to appear on the screen.
A blue light (backlight) illuminates the
screen - this stays on for about five seconds
(or three seconds after the last button press,
if button presses have been made).
To turn off the radio, press and hold the power
button for about two seconds.
Lock
The lock is a dedicated slide switch. It has
two settings, lock and unlock.
When in the unlock position all buttons are
active when pressed. When in the lock
position, all buttons are disabled.
The lock switch can be set to lock while the
radio is in use. In this situation, each time a
button is pressed, a message appears briefly
on the bottom line of the screen reminding
you that the Key lock is ON.
The radio cannot be turned off using the
power button until the lock switch has been
set to the unlock position.

17
Central Navigator
While the radio is playing, the Central
Navigator button has three functions:
•As a volume control.
Push the button forward (UP) to
increase the volume and backward
(DOWN) to reduce the volume.
Its action can be heard immediately in
the headphones and is indicated on
the screen by the appearance of the
volume icon.
•As a scroll button.
Push the button to left and right to
scroll through the menus displayed
on the bottom line. Push left or right
to scroll left and right.
•To select a menu option.
Press the button vertically down when
you want to select the menu option in
view on the bottom line of text.
Info
Press info to step through the available
information transmitted along with the
audio signal for the station you are tuned to
and named on the upper line of text. The
display information is displayed on the
bottom line of text and includes the station
content, name, program information and
some technical broadcasting details.

18
Menu
The menu button is used to access the first
item in a list of options that are presented
on the bottom line of text when the menu
key is pressed. Other items are accessed
using the scroll button (described earlier).
There are four primary options: Station
order, Manual tune, Autoscan local and
Version number of the embedded software.
The menu button has a second function.
When held for several seconds, the radio
resets to the factory set values. All settings
you have modified or entered will be cleared.
This reset will also clear the station list which
your radio will have compiled automatically.
Preset
The preset function allows you to store up
to ten radio stations that can be quickly
selected for playing. Previous presets can
be overwritten when not required.
EQ
Each press of the eq button steps through
the six available equalisation presets and
applies the setting to the audio signal being
played.
The available presets are: Flat, MBass,
Monitor, Studio, Club and Arena. You can
identify the particular one applied from the
eq icon on the top line of the screen and the
table shown opposite.
Operation
The MOSDR011 Digital radio uses an LCD
screen and a unique key arrangement to
navigate its functions.
The screen has a set of custom icons (see
opposite) and a two-line, alphanumeric
display which can display up to sixteen
characters on each line.
Back light
The screen is illuminated blue when a button
is pressed as follows:
•For 5 seconds each time the radio is
turned on when internally powered by
its batteries.
•For a short period prior to shut down
when the power button is pressed to
turn off the radio.
•For up to 3 seconds after a button has
been pressed.
Continual pressing of keys to make the
back light come on will drain the batteries.

20
The radio may be powered by means of a
suitable external d.c. supply. In these
circumstances, when the adaptor
connector is inserted, the radio circuitry
detects this and turns on the backlight. The
backlight remains on for the time the
external supply is used. This power supply
could be a conventional mains power
adaptor with the properties detailed on the
Technical specifications page.
You cannot change these timed settings.
Additional information
Wrapping
In most cases when navigating a menu, the
list will wrap to the start of the menu - it will
appear to be an endless loop.
New
In most cases, if a menu calling button is
pressed while in another menu list, the new
menu is displayed.
Timeout
If during the navigation of any menu there is
no button-press for a period of seven
seconds, the radio returns to the play
screen. In general, when a timeout
completes, the display will return to the top-
level interface.
Power down
On power down, the current settings and
station lists are saved, so that when the radio
is next switched on, these settings are
retained. This will not happen if a factory
reset has been made prior to power off. The
settings will then be the default factory
settings.
Non-volatile memory
The parameters (e.g. volume, presets,
display mode) are saved in a non-volatile
memory device every time the parameter
is changed.
For station list and current stations, the
parameters are updated after the current
action has been completed (i.e. after a
station scan has completed, or after a tuned
station is changed). This means that if you
power down during Scanning or Station
tuning, the Station list may be lost. On the
following power up, the Station list will be
empty and the parameters will return to the
default values.
