Sangean DPR-26BT Operating Instructions Manual page 32

If you use the radio powered from batteries, the battery light will be off
until the batteries are exhausted. The battery light will then show red for
a 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
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 battery charge indicator stops
flashing.
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, we
recommend that the batteries are fully charged before the radio is put to
one side (charge light show steady green).
If you intend not to use your radio for some months, then we recom-
mend 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 re-
chargeable 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 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.
. Keep batteries out of the reach of children.
. Do not heat, open, puncture, mutilate or dispose of batteries by burning.
. 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 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.
