Leaking battery acid may lead to chemical burns.

Batteries (particularly lithium batteries) can ex-
plode if used improperly.
• Never attempt to recharge batteries.
• Only use batteries of the same or equivalent type.
• You may not heat or short circuit batteries and stor-
age batteries or dispose of them in fire.
• Do not expose batteries and storage batteries to
direct sunlight.
Extended listening at high volumes may lead to
hearing loss.
To avoid damage to health, avoid extended listening at
high volumes.
• When the volume is set high, always keep a certain
distance from the device and never place your ear
directly on the speaker.
• If a speaker is set to full volume, this may produce
very high sound pressure. This may have psycholog-
ical consequences and also cause physical injury.
Children and pets are particularly at risk. Set your
signal source device volume control to a low setting
before turning on the power.
