12 .  Use only with the cart, stand, tripod, bracket, or table specified by the 

manufacturer, or sold with the apparatus . When a cart is used, use caution 
when moving the cart/apparatus combination to avoid injury from tip-over .

13 .  Unplug this apparatus during lightning storms or when unused for long periods of time . 
14 .  Refer all servicing to qualified service personnel . Servicing is required when the apparatus 

has been damaged in any way, such as power supply cord or plug is damaged, liquid 
has been spilled or objects have fallen into the apparatus, when the apparatus has been 
exposed to rain or moisture, does not operate normally, or has been dropped .

15 .  To completely disconnect this apparatus from the AC mains, disconnect the power supply 

cord plug from the AC receptacle .

16 .  WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain 

or moisture .

17 .  Do not expose this equipment to dripping or splashing and ensure that no objects filled 

with liquids, such as vases, are placed on the equipment .

18 .  The mains plug of the power supply cord shall remain readily accessible .

• 

Ensure that the room in which you use this product is wired in accordance with the local

ment to a warm one, allow the product to acclimatize to room temperature before using it .

• 

Do not overload wall outlets and extension cables as this may result in fire and electric 
shock .

WARNING

Danger of hearing damage due to sudden high sound pressure levels!

Audio signals that are present at switch-on of the product or that can be present during 
operation, can create sudden, very high sound pressure levels which can damage your 
hearing .

 

X

Always lower the output level of the audio source before connecting it to the loudspeaker 
or starting it (pressing “play”) .

This loudspeaker can be used for commercial purposes . Commercial use is subject to the rules
