Note: When the Auxiliary Input socket is not in use you must ensure that nothing is plugged into the socket in order to enable use of the DAB, FM and Bluetooth operating modes of your radio.

Battery operation

1. Remove the Battery cover on the rear of the unit by pushing the 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, 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 eco4 Bt is used via the

mains whenever possible with battery operation for occasional use only.

IMPORTANT: The batteries should not be exposed to excessive heat such as sunshine, ﬁ re 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.

Mains operation

1. Place your radio on a ﬂ at surface.

2. Plug the mains lead into the Mains Input socket located on the rear of your radio ensuring that the plug is pushed fully into the socket.

3. Plug the other end of the mains lead into the wall socket and switch on the wall socket. The mains LED will light. Whenever the mains is used the batteries are automatically disconnected.

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.

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. The display will show 'WELCOME' for a few seconds. 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 ﬁ rst 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 ﬁ rst station (in numeric-alpha

order 0...9...A....Z) will be selected. The ﬁ rst station in the list of stations

found will be played.

6. If no stations are found then 'OFF AIR' 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 ﬁ nd stations as described on page 9 (see Finding new stations on page 9).
