		• Do not spill any liquids on the equipment and do not drop any objects through the ventilation slots
			in the equipment.
		• The equipment may be used in dry rooms only.
		• Before connecting the equipment to power, check that the AC mains voltage stated on the included
			power supply is identical to the AC mains voltage available where you will use the equipment.
		• Operate the equipment with the included power supply with an output voltage of 12 VDC only. Using
			adapters with an AC output and/or a different output voltage may cause serious damage to the
			equipment.
		• The equipment should be opened, serviced, and repaired by authorized personnel only. The equip-
			ment contains no user-serviceable parts.
		• Operate the equipment off voltages between 90 VAC and 240 VAC only. Using a different power volt-
			age may cause serious damage to the unit!

			Disconnect the power cable from the power outlet immediately and have the equipment checked
			by AKG service personnel.
		• Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc.
			and do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or
			shock.
		• To avoid hum or interference, route all audio lines, particularly those connected to the microphone
			inputs, away from power lines of any type. If you use cable ducts or conduits, be sure to use sep-
			arate ones for the audio lines.
		• Clean the equipment with a moistened (not wet) cloth only. Be sure to disconnect the equipment from
			the power outlet before cleaning the equipment! Never use acidic or scouring cleaners or cleaning
			agents containing alcohol or solvents since these may damage the enamel and plastic parts.
		• Use the equipment for the applications described in this manual only. AKG cannot accept any lia-
			bility for damages resulting from improper handling or misuse.

The SR 470 has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reason- able protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is en- couraged to try to correct the interference by one or more of the follow ngi measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and the receiver.

•Connect the equipment into an outlet on a circuit different from that to which the receiver is connect ed.

•Consult the dealer or an experienced radio/TV technician for help.

Shielded cables and I/O cords must be used for this equipment to comply with the relevant FCC regulations.

Changes or modifications not expressly approved in writing by AKG Acoustics may void the user’s authority to operate this equipment.

The SR 470 complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this de- vice must accept any inter ference receiv ed, including interference that may cause undesired operation.

USA only: FCC CONSUMER ALERT

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to

certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from inter- ference received from any other device.

Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
