Battery operation
Battery operation using rechargeable batteries
IMPORTANT
When using rechargeable batteries, the battery switch must be
placed in Charge On / NiMH position. Batteries will only be charged
when the radio is switched off and connected to the AC adaptor.
IMPORTANT
Use only supplied AC power adaptor to power the radio or charge the
rechargeable batteries to avoid possible interference while listening
to the radio.
When the batteries are exhausted, an E will flash on the display. 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 AC adaptor.
If the radio is not to be used for any extended period of time it is
recommended that the batteries be removed from the radio.
IMPORTANT
The batteries should not be exposed to excessive heat such as direct
sunlight, fire etc. After use, disposable batteries should be taken to
a suitable recycling center. Batteries should not be disposed of by
incineration.
