Battery operation using alkaline batteries
(also see page 25)
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.
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.

Battery operation using rechargeable batteries
(also see page 25)
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.
8. Under some conditions the charging indicator light may switch off after
fl ashing only briefl y. This may happen if the batteries are already freshly
charged, or if the radio detects that you may be attempting to recharge
alkaline batteries. In these cases the charging will be stopped.
Note: You should never attempt deliberately to recharge alkaline
batteries in the radio. Attempted recharging of alkaline batteries can
be dangerous.
• 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.
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 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.

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
