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
FM band be used wherever possible as better results in terms of quality
and freedom from interference will usually be obtained than on the MW
or LW bands.
