Optimus CTR-115 - Manual (Page 11)

• Do not increase the volume once you have established a
comfortable listening level. 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 the earphone while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and could be il-
legal in some areas.
Even though some earphones let you hear some outside
sounds when listening at normal volume levels, they still can
present a traffic hazard.
