Optimus SCP-104 Cassette Player User Manual

Once you set the volume, do not increase it. Over time,
your ears adapt to the volume level, so a volume level
that does not cause discomfort might still damage your
hearing.
Traffic Safety
Do not wear headphones while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and can be il-
legal in some areas.
Even though some headphones let you hear some outside
sounds when listening at normal volume levels, they still can
present a traffic hazard.
