A Few Words about Batteries…  
Rechargeable batteries  
Your Roberts Expression radio has been designed to use a choice of  
power sources. You may plug it into the mains using the supplied high-  
efficiency 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.  
Your Expression 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.  
It is very important that you read the advice and warnings given  
below.  
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.  
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 fitted, then set the switch to the Alkaline position.  
This position minimises the power consumption when the radio is  
powered from the mains.  
b. If Alkaline batteries are fitted, then set the switch to the Alkaline  
position.  
c. If Rechargeable batteries are fitted, then set the switch to the  
NiMH position. Your radio is designed to use Nickel-Metal-Hydride  
rechargeable batteries. No other type of rechargeable battery should  
be used in the radio.  
We recommend that the rechargeable batteries that you use should  
be from a quality brand, and should be of at least 2500mAh capacity.  
Batteries of this capacity should power your radio for between 10 and  
15 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. Higher capacity batteries are  
available and will give longer life, but will generally be more expensive.  
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.  
Before you first install a new set of rechargeable batteries into your  
radio you should first make sure that the battery type switch beneath the  
battery cover is in the NiMH position. Install the batteries arranging them  
as shown inside the battery compartment. Plug the mains adaptor into the  
radio and then into the mains socket. While the batteries are charging the  
charge indicator should show a flashing green light. When the batteries  
are fully charged the indicator will stop flashing 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  
first fitted, but it is normal for a set of batteries to take several hours to  
charge fully (this can be between 3 and 7 hours depending on the battery  
capacity and their initial state of charge).  
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.

23  
If you use the radio powered from the batteries, the charge/low battery  
indicator light will be off until the batteries are exhausted. The charge/  
low battery indicator light will then show red for a short while before the  
radio switches itself off. It does this in order that the batteries are not  
excessively discharged. This would otherwise damage the batteries and  
shorten their life.  
To avoid danger and risk of injury, please follow  
these guide lines  
Improper use of batteries may result in leakage of fluid, overheating  
or explosion. Battery fluid is corrosive and may also be toxic. Battery  
fluid can cause skin burns, can damage the eyes, and can be harmful if  
swallowed.  
If you use the radio powered from the mains with rechargeable batteries  
fitted, the charging process is suspended until you switch off the radio.  
When you switch off the radio using its On/Off button charging will  
then resume. If the batteries have already been charged then they will  
only charge for a few more minutes before the charge indicator stops  
flashing.  
1. Keep batteries out of the reach of children.  
2. Do not heat, open, puncture, mutilate or dispose of batteries by  
burning.  
3. Do not mix different battery types or old and new batteries. Always  
replace all the batteries at the same time.  
If you only listen to your radio for short periods, you do not need to  
connect your radio to the mains to charge the batteries every time that  
you use it. However, if the radio is not to be used for a few weeks, then  
we recommend that the batteries are fully charged (charge light shows  
steady green) before the radio is put to one side.  
4. Do not carry or store batteries such that metal objects may contact  
the end caps.  
5. Remove batteries from the radio if they are worn out or if you are  
storing it for a long time.  
6. Remove old or worn out batteries promptly, and recycle or dispose of  
them according to the regulations applicable to your location.  
7. If a battery does leak, remove all batteries from the product, taking  
care to avoid directly touching the leaked fluid. If the fluid contacts  
skin or clothes wash with water immediately. Before inserting new  
batteries, thoroughly clean the battery compartment with a damp  
paper towel, or follow the battery manufacturer’s advice for clean  
up.  
If you intend not to use your radio for some months, then we recommend  
that the batteries are removed and put away, keeping them in a cool  
place out of reach of children, away from moisture and such that no metal  
object can contact the battery terminals.  
With care, rechargeable batteries can last a long time and can operate for  
many hundreds of charge and discharge cycles. When your rechargeable  
batteries can no longer power your radio adequately, please dispose of  
them responsibly using a local battery recycling facility.
