Battery operation using alkaline batteries

(also see page 23)

1. Remove the battery cover on the back of the unit by pushing the battery door in slightly and then downwards in the direction of the arrows in the diagram.

2. Slide the switch inside the battery compartment to the Alkaline position.

3. Insert four LR20 (D size) alkaline batteries into the spaces in the compartment. Take care to ensure all batteries are inserted with the correct polarity as shown on the back of the radio. Then replace the battery cover.

• Important: when using alkaline batteries the battery switch must be placed in the alkaline position. Failure to do so could result in serious damage to the batteries or radio.

• When the batteries are exhausted, the charge indicator light will show red for a short while. The radio will then switch itself off. It may not be

possible to switch the radio back on until the batteries are replaced, or until the radio is connected to the mains adaptor.

• 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 duologic is used via the

AC adaptor whenever possible with battery operation for occasional or stand-by use only. If extended listening using batteries is anticipated, then the use of rechargeable batteries is recommended.

Battery operation using rechargeable batteries

(also see page 23)

1. Remove the battery cover on the back of the unit by pushing the battery door in slightly and then downwards in the direction of the arrows in the diagram.

2. Slide the switch inside the battery compartment to the NiMH/NiCad position.

3. Insert four Rechargeable LR20 (D size) batteries into the spaces in the compartment. Take care to ensure all batteries are inserted with the correct polarity as shown on the back of the radio. The radio is designed to be used with Nickel Metal Hydride (NiMH) or Nickel Cadmium (NiCad) rechargeable batteries.

4. Plug the mains adaptor into your radio and then plug the adaptor into the mains.

5. The Charge light will ﬂ ash green indicating batteries are charging. Batteries will be fully charged in around 7 hours. The charge light shows a steady green light when the battery charging is complete.

• Important: when using rechargeable batteries the battery switch must be placed in the NiMH/NiCad position. Batteries will only be charged when the radio is switched off and connected to the AC adaptor.

• When the batteries are exhausted, the charge indicator light will show red for a short while. The radio will then switch itself off. It may not be

possible to switch the radio back on until the batteries are recharged, or until the radio is connected to the mains adaptor.

• 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, 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.

Using the AC adaptor

1. Insert the adaptor plug into the DC in socket on the right hand side of your radio.

2. Plug the adaptor into a standard 13A mains socket outlet. Whenever the adaptor is plugged in to the radio and switched on at the mains the batteries are automatically disconnected. If the adaptor is plugged in to the radio but not switched on then the radio will run from the batteries if ﬁ tted.

The AC adaptor should be disconnected from the mains supply and

the radio when not in use.

• 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.

Operating your radio - DAB

1. Carefully extend the telescopic aerial.

2. Press the On/Off button to switch on your radio. The display will show "Welcome to DAB".

3. If this is the ﬁ rst time the radio is used a quick scan of the UK Band III DAB channels will be carried out. If the radio has been used before the last used station will be selected.

4. During the scanning process, the lower line of the display shows a bar-graph indicating progress of the scan.

5. When the scanning is completed the ﬁ rst station (in numeric-alpha

order 0...9...A....Z) will be selected.

6. If the station list is still empty after the scan your radio will display "No stations available".

7. If no signals are found it may be necessary to relocate your radio to a position giving better reception. Then, either switch your radio off and on again, or press the Auto Tune button to repeat the scan.

Selecting a station - DAB

1. The top line of the display shows the name of the station currently selected.

2. Rotate the Tuning control to scroll through the list of available stations on the lower line of the display. Stop rotating the Tuning control when you ﬁ nd the station that you wish to hear.

3. Press and release the Tuning control to select the station. The display may show "Now tuning..." while your radio ﬁ nds the new station.

4. Adjust the Volume control to the required setting.

Note: If after selecting a station the display shows "Not Available" it may be necessary to relocate your radio to a position giving better reception.

The use of radio station presets for selecting your preferred radio stations is described on page 17.
