Safety Precautions

Warning: Do not attempt to open the back cover or power adapter. Opening or removing covers may expose you to dangerous voltage or other hazards. There are no user-serviceable parts inside. Refer servicing to qualified personnel.
The exclamation mark inside a triangle symbol (!) alerts users to important operating and maintenance instructions found in the accompanying literature.
The lightning flash with an arrowhead symbol inside a triangle symbol (⚡) alerts users to the presence of un-insulated "hazardous voltage" within the product enclosure that may be of sufficient magnitude to induce a risk of electric shock.
Pull out the power cord from the plug end; do not pull the wire.
Keep the speaker away from heat sources.
Do not open the speaker unit or change circuitry, as this may cause damage or electric shock.
If not using the unit for an extended period, unplug it and store it in a cool, dry place.
Ensure the speaker is well-ventilated and kept in a dry location. Keep it approximately 4 inches away from walls or objects.
