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.
