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 ash 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.
