General  
Do not allow this radio to be exposed to water, steam or sand. Do not leave  
your radio where excessive heat could cause damage such as in a parked  
car where the heat from the sun can build up even though the outside  
temperature may not seem too high. It is recommended that the DAB band  
be used wherever possible as better results in terms of quality and freedom  
from interference will usually be obtained than on the FM band.  
The name plate is located on the back of your radio.
