If you use the radio powered from the batteries, the charge indicator light 
will be off until the batteries are exhausted.  The charge 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.

If you use the radio powered from the mains with rechargeable batteries 
fi tted, 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 
fl ashing.

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.

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 thoughtfully. 

 

To avoid danger and risk of injury, please follow 
these guide lines

Improper use of batteries may result in leakage of fl uid, overheating 
or explosion. Battery fl uid is corrosive and may also be toxic.  Battery 
fl uid can cause skin burns, can damage the eyes, and can be harmful if 
swallowed.

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.

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 fl uid. If the fl uid 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.
