Battery operation
1. Remove the battery cover located underneath the unit by applying
pressure to the catch in the direction shown by the arrow and then
lifting off the cover.
2. InsertfourLR14(Csize)batteriesintothespacesinthecompartment.
Take care to ensure all batteries are inserted with the correct polarity
asshownnext to the batterycompartment.Replacethe battery cover.
3. Reduced power, distortion and 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.
We would recommend for economy that the radio is used via the AC
adaptor whenever possible with battery operation for occasional use
only.
If long term battery powered use is required, we recommend using
the Eco power saving mode, as described on page 30. The use of the
Eco power saving mode will maximise battery life if only occasional
use is intended and where the radio is not connected to the mains at
other times.
IMPORTANT: The batteries should not be exposed to excessive heat
suchassunshine,fireorthelike.Afteruse,disposablebatteriesshould
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.

Using the AC adaptor
1. Place your radio on a flat surface.
2. Plug the mains adaptor into the DC input socket located on the rear
of your radio (marked 'DC') ensuring that the plug is pushed fully into
the socket.
3. Plug the other end of the mains adaptor into a standard mains socket
outletandswitchonthewallsocket.Thedisplaywillshow'WELCOME'
for a few seconds and '00:00' will be shown on the display.
Whenever the adaptor is used the batteries are automatically
disconnected.
The AC adaptor should be disconnected from the mains supply and
from the radio when not in use.
IMPORTANT: The mains adaptor is used as the means of connecting the
radiotothemainssupply.Themainssocketusedfortheradiomustremain
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.
Use only the mains adaptor provided with the product, or a genuine
replacement provided by Roberts Radio. The use of alternative adaptors
may invalidate the guarantee.

Operating your radio - DAB
1. Carefully extend the telescopic aerial. The aerial should be fully
extended and positioned vertically for optimum reception.
2. Press and release the On/Off button to switch on your radio. After
each use the radio will remember the mode used and then switch on
in that mode the next time that it is used.
3. If this is the first time the radio is used a scan of the Band III DAB
channels will be carried out. This is known as 'Auto tune'. If the radio
has been used before the last used station will be selected.
4. During Auto tune each group of stations will be detected and the
station count will be updated.
5. When the Auto tune is completed the first station (in numeric-alpha
order0...9...A....Z)willbeselected.Thefirststationinthelistofstations
found will be played.
6. If no stations are found then 'OFFAIR' will be displayed and it may be
necessary to relocate your radio to a position giving better reception.
You should then carry out an auto tune to find stations as described
on page 9 (see Finding new stations on page 9).
• Your radio has an indicator on the display to indicate the strength
of the DAB radio signal being received.
Note:Whenfirst switched on, the radio willsetthevolumetoamoderately
high level, in case the broadcast is very quiet. After you have set the
volume, the radio will remember the setting that you have applied for the
