A Few Words about Batteries…
Your Roberts ecologic 1 radio has been designed to use a choice of
power sources. You may plug it into the mains using the supplied high-
effi ciency adaptor, or for listening away from the mains you may use
either alkaline or rechargeable batteries. We do not recommend the use
of carbon-zinc or zinc-chloride batteries.
It is very important that you read the advice and warnings given
below.
1) Whichever type of batteries you choose to use, it is very important
that the battery selection switch under the cover is set to the correct
type.
a. If no batteries are fi tted, then set the switch to the Alkaline position (to
the left as viewed from the back of the radio). This position minimises
the power consumption when the radio is powered from the mains.
b. If Alkaline batteries are fi tted, then set the switch to the Alkaline
position (to the left as viewed from the back of the radio).
c. If Rechargeable batteries are fi tted, then set the switch to the NiMH
position (to the right as viewed from the back of the radio). Your radio
is designed to use Nickel-Metal-Hydride rechargeable batteries. No
other type of rechargeable battery should be used in the radio.
2) NEVER mix old and new Alkaline batteries. The old batteries may
suffer damage and leak which will damage your radio and whatever
the radio is standing on.
3) NEVER mix old and new Rechargeable batteries. This may
result in unreliable charging and shortened battery life. Never mix
Rechargeable batteries of different types or capacities even if they
are new.
4) NEVER mix Alkaline and Rechargeable batteries. The recharging of
Alkaline batteries can be very dangerous.
Rechargeable batteries
Your ecologic 1 radio uses a range of methods to ensure correct and safe
charging of Rechargeable Nickel-Metal-Hydride batteries. These work
to protect your batteries from excessive charge and discharge. These
protections can only work properly if the advice above is followed. In
particular, the radio will not be able to correctly charge batteries if they are
a mixture of different brands, or different ages, or different capacities.
We recommend that all the rechargeable batteries used in your radio
are bought together as a set. They should always be charged together
and discharged together and not “borrowed” from time to time for other
applications. This will ensure that they give their optimum performance
in your radio.
We recommend that the rechargeable batteries that you use should
be from a quality brand, and should be of at least 2000mAh capacity.
Batteries of this capacity should be able to power your radio for between
10 and 20 hours depending upon the volume of the radio, whether DAB
or FM mode is used (DAB mode uses slightly less power than FM), and
also depending on the condition of the batteries.
Before you fi rst install a new set of rechargeable batteries into your
radio you should fi rst make sure that the battery type switch beneath
the battery cover is in the NiMH position. Install the batteries arranging
them as shown on the back of the radio. Plug the mains adaptor into a
mains socket and then into the radio. While the batteries are charging the
battery indicator should show a fl ashing green light. When the batteries
are fully charged the indicator will stop fl ashing and will show a steady
green light. The time taken to charge the batteries will depend on how
much charging they require. New batteries may be partly charged when
fi rst fi tted, but it is normal for a set of batteries to take several hours to
charge fully (this can be between 5 and 8 hours depending on the battery
capacity and their initial state of charge).
