General
Do not allow this unit to be exposed to dripping or splashing. 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 FM band be used when ever possible as better results in
terms of quality and freedom from interference will usually be obtained
than on the MW band.
