Battery operation using alkaline batteries
1. Remove the battery cover on the back of the unit by sliding the cover
in the direction of the arrow.
2. Slide the switch inside the battery compartment to the Alkaline position.
3. Insert four LR6 (AA 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 battery 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 ecologic 1 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
1. Remove the battery cover on the back of the unit by sliding the cover
in the direction of the arrow.
2. Slide the switch inside the battery compartment to the NiMH position.
3. Insert four Rechargeable LR6 (AA 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) rechargeable
batteries.
4. Plug the mains adaptor into your radio and then plug the adaptor into
the mains.
5. The battery light will flash green indicating batteries are charging.
Batteries will be fully charged in around 7 hours. The battery 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 battery 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 sunshnie,
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
Your radio is supplied with a Mains Adaptor.
1. Place your radio on a at surface.
2. Insert the adaptor plug into the DC socket located on the left hand
side of your radio.
3. Plug the adaptor into a standard 13 amp mains socket outlet.
Whenever the adaptor is used with the radio, it will take power from
the mains rather than from the batteries.
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.
Lock switch
