Precautions

The 20/20 AD is a rugged device with extensive electronic protection. However, you should observe the same

reasonable precautions that apply to any piece of audio equipment:

• Always use the correct line voltage.

• Do not install the 20/20 AD in a closed, unventilated rack, or directly above heat-producing equipment such

as power amplifiers.

• Never attach audio power amplifier outputs (speaker outputs) directly to any of the 20/20 AD's connectors.

• To prevent fire or shock hazard, do not expose the 20/20 AD to rain or moisture.

This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict

accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has

been type tested and found to comply with the limits for a Class A computing device in accordance with the

specifications in Subpart J of Part 15 of FCC Rules, which are designated to provide reasonable protection against

such interference in a residential installation. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause interference to radio or television reception, which can be

determined by turning the equipment OFF and ON, the user is encouraged to try to correct the interference by one

or more of the following measures:

Reorient the receiving antenna

Relocate the computer with respect to the receiver

Move the computer away from the receiver

Plug the computer into a different outlet so that the computer and receiver are on different

branch circuits.

If necessary, the user should consult the dealer or an experienced radio/television technician for additional

suggestions. The user may find the following booklet prepared by the Federal Communications Commission

helpful: "How to identify and Resolve Radio/TV Interference Problems."
