Water Resistance Rating
• To ensure that the speaker is water resistant,
remove all cable connections and tightly close
the rubber cover.
• Exposing the speaker to liquids without closing
the rubber cover may result in permanent
damage to the speaker.
• Do not expose the speaker to water while
charging, as doing so may result in permanent
damage to the speaker or power source.
• Listening at a high volume for prolonged periods
of time poses a risk of hearing loss. Avoid
listening at a high volume for a prolonged period
of time.
• Maintain adequate distance from the speaker
and never hold the speaker to your ear.
• Set the volume on the playback device to a low
level before starting playback on the speaker. If
you set the playback device to full volume, very
high noise pressure may cause organ damage
and adverse psychological effects. Children and
pets are particularly at risk in this respect.
Warning:
Risk of Hearing Loss
