Battery operation using alkaline batteries
(also see page 23)
1. Ensure your radio is disconnected from the mains supply and the aerial is fully retracted.
2. Open the battery cover on the base of the unit by using a fl at bladed screwdriver to loosen the screw securing the battery cover.
3. Slide the switch inside the battery compartment to the Alkaline position.
4. 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 inside the battery compartment.
5. Close the battery cover and gently tighten the screw using a fl at bladed screwdriver. Do not overtighten.
• 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/low battery indicator 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 Expression is used via
the AC adaptor whenever possible with battery operation for occasional 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. Ensure your radio is disconnected from the mains supply and the aerial is fully retracted.
2. Open the battery cover on the base of the unit by using a fl at bladed screwdriver to loosen the screw securing the battery cover.
3. Slide the switch inside the battery compartment to the NiMH position.
4. 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 inside the battery compartment. The radio is designed to be used with Nickel Metal Hydride (NiMH) rechargeable batteries.
5. Close the battery cover and gently tighten the screw using a fl at bladed screwdriver. Do not overtighten.
6. Plug the mains adaptor into your radio and then plug the adaptor into the mains.
7. The Charge light will fl ash green indicating that the batteries are charging. Batteries will be fully charged in around 3 - 7 hours depending on their capacity. 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 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/low battery 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 rear 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.
