Fixing instructions
Please read the following installation procedure and familiarise yourself
with each of the steps before starting work. This will help ensure that the
installation proceeds smoothly and without error. You should also read the
cautions on page 40 of this booklet.
1. Determine the desired location for the radio. This must be away from
sources of heat, steam and naked flames (away from kettles, toasters,
cooker hobs, and the like).
2. Check that DAB and FM reception is possible at the desired
location.
3. Adjust the aerial for optimal DAB and FM reception. For optimum
reception the aerial may need to run vertically rather than horizontally.
Try to avoid running the aerial near wiring, water pipes, or other metal
structures. You may need to experiment to determine the best position
for the aerial. Use adhesive tape as a temporary fixing for the aerial,
since holding it may affect reception.
4. Check that the aerial and mains lead can be safely routed and secured
before fitting the radio.
5. Loosen the thumb screws on the sides of radio to free the mounting
bracket. Lift the mounting bracket and tighten the thumb screws.
6. Offer the radio to the desired location to determine the precise location
of the mounting bracket against the underside of cupboard.
7. Using a soft pencil, mark the underside of the cupboard with the
location of the mounting bracket.

Mains operation
1. Position your RDK2 touch panel radio as previously described.
2. Plug the mains plug into a wall socket and switch on the wall
socket.
• IMPORTANT: The mains plug 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
plug should be removed from the mains socket outlet
completely.
8. Completely undo the thumb screws from the sides of the radio and
remove the mounting bracket.
9. Hold the mounting bracket against the pencil marks under the cupboard
and use the pencil to mark drill centres for the fixing screws (4).
10. Your radio is supplied with screws of two lengths. Be sure to use screws
of appropriate length for the cupboard material. If those provided are
not suitable for your needs, please use screws with a similar diameter
and head design.
IMPORTANT: Before drilling holes and applying screws, please make
sure that the screws selected are not too long. Excessively long
screws may damage the interior of your cupboard.
11. Drill short pilot holes for the screws in the underside of the cupboard.
(Pilot hole diameter typically 2.5mm, suggested drill depth not more
than 12 - 14 mm)
12. Using the screws to fit the mounting bracket to the cupboard taking
care not to over tighten them.
13. Offer the radio to the fixed mounting bracket and re-insert the two
thumb screws.
14. Adjust the height of the radio beneath the cupboard as needed and
tighten the thumb screws. Tighten by hand only.
15. Secure the mains lead and aerial as needed. The aerial has a loop
formed at the free end. This can be fixed as needed. Insert the mains
plug in the nearest convenient mains socket and secure the mains
lead so that it does not obstruct working in the kitchen.

7
Operation modes
Your radio has 4 operating modes, DAB, FM, Playlist mode and Auxiliary
input.
1. Press the Band button to change the operation mode between DAB,
FM, Playlist modes.
• DAB mode is used for listening to Digital Radio broadcasts and for
recording programmes to a memory card.
• FM mode is used for listening to FM radio broadcasts.
• Playlist mode is used to play back digitally recorded programmes and
for listening to MP2 and MP3 files.
• The RDK2 has a Auxiliary input socket which can be used as an
amplifier and loudspeaker system for external MP3 players, portable
compact disc players and similar devices.
Auxiliary input mode is automatically selected when a 3.5mm stereo
plug is inserted into the socket behind the cover on the front of the
radio.

Using the touch panel
Your radio has a stylish touch panel instead of conventional buttons. This
is designed so that it is easy to clean using a slightly damp cloth. Do not
use solvents.
Be sure to dry of any moisture from the touch panel after cleaning, since this
may otherwise affect the reliability of the touch panel sensor system.
To operate the buttons simply touch the button area with the tip of a finger
for about half a second. Some operations such as storing radio presets,
require a longer operation of the button. In this case simply keep your
finger held on the button area for 2-3 seconds until the display on the
radio shows that the command has been accepted.
You may find that at first, the radio does not always detect that you have
touched a button. If so, try touching with a little more pressure, a little
higher or lower, or for slightly longer. You will soon find the optimum touch
needed to control your radio.
Using an alternative aerial
Your radio is supplied with a simple wire aerial. This will be satisfactory in
the majority of installations. However, if reception is poor in your kitchen,
you may wish to consider connecting the radio to an alternative aerial.
The supplied aerial is secured by a small plastic cover. Use a cross-head
screw driver to remove this cover. The aerial may then be removed by
pulling with a twisting action.
Once the aerial has been removed, a standard F-type socket is available
to which an alternative aerial may be connected.

Operating your radio - DAB
1. Place the wire antenna so that it is as straight as possible extending
either above or below the radio.
2. Plug the mains lead into a wall socket and switch on the wall
socket.
4. The radio will then display "Clock not Set...". The radio will scan for
DAB signals and if a DAB signal is found it will then show the current
time and date in the display.
5. If no signal is received the radio will continue to display "Clock not
Set". Try repositioning the antenna. Touch the On/Standby button and
the radio will re-scan. If a signal is found the radio will then tune to a
station and set the clock as soon as the time information is received.
If necessary reposition again and touch the Auto tune button to re-
scan until stations are found.
