Safety Instructions

For your safety

1.	Read, Follow, And Save All Instructions – Read and follow the complete safety and operating
	instructions in this owner’s guide before using the unit. Save this guide for future reference.
2.	Pay Attention To Warnings – Observe all warnings on the unit and in the guide.
3.	Do Not Let Objects Or Liquid Enter The Unit – Take care to prevent objects or liquids
	from entering this unit. Do not use near a bathtub, washbowl, kitchen sink, laundry tub, in
	a wet basement, near a swimming pool, or anywhere else that water is present. Clean only
	as directed on page 18.
4.	Maintain Proper Ventilation – Place the unit so nothing interferes with its proper ventilation.
	Do not place on a bed, sofa, or similar surface that may block the ventilation openings. Do not put
	it in a bookcase or cabinet that may keep air from flowing through its ventilation openings.
5.	Avoid Excessive Heat – Do not place the unit near heat sources such as radiators, stoves,
	or other appliances (including amplifiers) that produce heat.
6.	Use Proper Power Sources – Plug the unit into a proper power supply, as described in the
	operating instructions or as marked on the unit. This unit has a polarized alternating current
	line plug (one blade is wider than the other). As a safety feature, the plug fits into the power
	outlet only one way. If you have trouble inserting it, reverse the plug. If it still does not fit,
	your outlet may be obsolete and needs to be replaced. Contact an electrician. Do not
	change the plug to defeat this safety feature.
7.	Protect The Power Cord – Route all power cords so that they are not likely to be walked on
	or pinched. Pay particular attention to cords at plugs, at the point where the cord connects
	to the unit, and at outlets on the unit.
8.	Take Precautions When Unit Is Not In Use – If the unit will not be used for an extended
	period, unplug from the outlet and remove the batteries.
9.	Be Careful With Carts And Stands – Do not place this unit on an unstable cart, stand,
	tripod, bracket, or table. The unit may fall, causing serious injury to a person or damage to
	the unit. For advice on use of a particular cart, stand, tripod, bracket, or table, contact
	Bose® Corporation. Be careful when moving the unit and cart combination. Quick stops,
	excessive force, and uneven surfaces may cause it to overturn.
10.	Avoid Power Lines – Do not install external antennas near overhead power lines or other
	electric light or power circuits, nor where an antenna can fall into such circuits or power lines.
11.	Ground All Outdoor Antennas – If an external antenna or cable system is connected to this
	unit, be sure the antenna or cable system is grounded. This will provide some protection
	against voltage surges and built-up static charges.
	Section 810 of the National Electrical Code ANSI/NFPA No. 70 provides information with
	respect to proper grounding of the mast and supporting structure, grounding of the lead-in
	wire to an antenna discharge unit, size of the grounding conductors, location of antenna-
	discharge unit, connection to grounding electrodes, and requirements for the ground
	electrode. Refer to the antenna grounding illustration.

12. Obtain Authorized Service When It Is Indicated – Do not attempt to service this unit
yourself. All servicing should be provided by authorized service personnel when:
A.	The power supply cord or the plug has been damaged, or
B.	Objects have fallen or liquid has spilled into the unit, or
C.	The unit has been exposed to rain, or
D.	The unit does not appear to operate normally or exhibits a marked change in performance, or
E.	The unit has been dropped or the cabinet damaged.

Note to CATV system installer:

This reminder calls the CATV system installer’s attention to Article 820-40 of the NEC (of USA) that provides guidelines for proper grounding. It specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as is practical.
