RD-41 Digital radio features
The Roberts RD-41 radio provides the following features in an
attractive compact unit.
Radio
The RD-41 can receive DAB and FM (with RDS) wavebands.
Electronic programme guide (EPG)
The electronic programme guide provides start/stop times and program
information similar to that provided for digital TV broadcasts. The EPG
typically provides programme information for up to seven days.
SD card
An SD card can be used in your radio for recording, playing back
previously recorded radio programs or playing back MP2, MP3 and
WMA files transferred from a PC.
Record timers
The RD-41 has twelve timers which can be used to record from DAB
radio to SD card. Timers may be set using the Electronic Program
Guide (EPG), or to specified times. The timers allow repeated
recordings to be made of broadcast series (daily, weekly, weekdays
or weekends).
Alarms
The RD-41 has twelve alarms which can be set to wake you to either
a radio station, playlist (SD card files) or a buzzer.
High resolution display
A large display panel provides an easy-to-read clock display when the
radio is in standby mode. When the radio is in use, the large display
makes it easier to choose which radio station to listen to and allows
text messages which are broadcast to be read without scrolling.
Auxiliary input
The RD-41 can be used as an amplifier and loudspeaker system for
external MP3 players, compact disc players and similar devices.
Headphone output
A standard 3.5mm headphone socket is provided for private
listening.
Line output socket
A standard 3.5mm Line output socket is provided for connecting the
audio signal from the radio to an external amplifier or recorder.
USB socket
Your radio has a USB connection to connect your PC. The USB port
can be used to copy files to and from your SD card.

Battery operation
1. Remove the Battery cover on the rear of the unit by pushing
battery door in and downwards.
2. Insert six LR20 (D size) batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct
polarity as shown inside the battery compartment. Replace the
battery cover.
3. Reduced power, a low battery indicator , distortion or a ‘stuttering’
sound are all signs that the batteries may need replacing.
4. If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
IMPORTANT: The batteries should not be exposed to excessive heat
such as sunshine, fire or the like.After use, disposable batteries should
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.

If you need any further advice, please call our Technical Helpline on :-

Using the AC adaptor
1. Place your radio on a flat surface and insert the adaptor plug into
the DC socket located on the left side of your radio. The adpator
for use with your RD-41 should provide 9 volts DC output at 1.2
amps, centre pin positive.
2. Plug the adaptor into a standard 13 amp mains socket outlet.
Whenever the adaptor is used the batteries are automatically
disconnected.
We would recommend for economy that your radio is used via the
AC adaptor whenever possible with battery operation for occasional
use only.
IMPORTANT: The mains adaptor is used as the means of connecting
the radio to the mains supply. The mains socket used for the radio
must remain accessible during normal use. In order to disconnect
the radio from the mains completely, the mains adaptor should be
removed from the mains socket outlet completely.

Using an SD memory card with your radio
An SD card can be used in your radio for recording, playing back
previously recorded radio programs, or playing back MP2/MP3/WMA
files transferred from a PC.
Depending on the radio station a 512MB SD card will give typically
8 - 16 hours of recording time. If you are using a new SD card ensure
that it is formatted correctly (see page 28)
Many different brands and capacities of SD card are available. Your
RD-41 can use cards up to 2 GB. However, there are many different
card variants available and not all cards can be guaranteed to work
in the RD-41. In this application there is no performance benefit in
using high-speed cards. Note that the RD-41 is not compatible with
very high capacity cards using the SDHC standard.
Inserting and removing a card
To insert an SD card into your radio carefully push the card into the
SD card slot until it clicks. The card must be inserted gold contacts
first and with the label side to the rear of the radio. The SD card slot
is on the top left side of your radio.
To remove the card push the card in slightly and the eject mechanism
will lift it slightly allowing easy removal.
Note: The SD card should not be removed during a recording as
damage or corruption of files on the card may occur.
