There are nations and regions where the use of particular 5 GHz bands are prohibited outdoors, so do not use these products outside. 2.4 GHz radio waves are used by a variety of devices, as shown in lists 1 and 2 below. 1. Devices which use a 2.4 GHz radio wave frequency • Cordless phones • Cordless facsimiles • Microwave ovens • Wireless LAN devices (IEEE802.11b/g/n) • Wireless AV equipment • Wireless controllers for game systems • Microwave oven-based health aids • Video transmitter • Specific type of external monitor and LCD display 2. Less common devices which use a 2.4 GHz radio wave frequency • Anti-theft systems • Amateur radio stations (HAM) • Warehouse logistic management systems • Discrimination systems for train or emergency vehicles If these devices and the AV receiver are used at the same time, the audio may be undesirably stopped or disturbed due to a radio wave interference. Suggestions for improvement • Switch off the devices which emit the radio wave. • Place the interfering devices away from the AV receiver. • The AV receiver uses radio wave, and a third person can receive the wave on purpose or accidentally. Do not use the communication for important or fatal matters. • We assume no responsibility whatsoever for any error or damage of network environment or access device resulting from the use of this apparatus. 64 Confirm with the provider or access device maker for more information. ˙ Scope of Operation Use of the AV receiver is limited to home use. (Transmission distances may be reduced depending on communication environment.) In the following locations, poor condition or inability to receive radio waves may cause the audio to be interrupted or stopped: • In reinforced concrete buildings or steel framed or iron framed buildings. • Near large metallic furniture. • In a crowd of people or near a building or obstacle. • In a location exposed to the magnetic field, static electricity or radio wave interference from radio communication equipment using the same frequency band (2.4 GHz) as the AV receiver, such as a 2.4 GHz wireless LAN device (IEEE802.11b/g/n) or microwave oven. • If you live in a heavily populated residential area (apartment, townhouse, etc.) and if your neighbor`s microwave oven is placed near your AV receiver, you may experience radio wave interference. If this occurs, move your AV receiver to a different place. When the microwave oven is not in use, there will be no radio wave interference. ˙ Radio Wave Reflections The radio waves received by the AV receiver include the radio wave coming directly from the devices and waves coming from various directions due to reflections by walls, furniture and building (reflected waves). The reflected waves (due to obstacles and reflecting objects) further produce a variety of reflected waves as well as variation in reception condition depending on locations. If the audio cannot be received properly due to this phenomenon, try moving the location of the wireless LAN device a little. Also note that audio may be interrupted due to the reflected waves when a person crosses or approaches the space between the AV receiver and the wireless LAN device. • We assume no responsibility whatsoever for any damages resulting from the use of this apparatus except in the cases deemed acceptable under the applicable laws and regulations. • Operation in all environment is not guaranteed for wireless LAN. The communication may not be possible or have desirable communication speed. ˙ Precautions • Do not use this apparatus near an electronic device handling high-accuracy controls or weak signals. Doing so may cause an accident due to a malfunction of the device. • Do not use this apparatus in use prohibited location such as an aircraft equipment or a hospital. Doing so may cause an accident due to a malfunction of an electronic device or an electro-medical apparatus. Follow the instructions of the medical facilities. Electronic device which requires cautions Hearing aid, pace maker, other medical electronic devices, fire alarm, automatic door, and other automatic control device. When using a pace maker or other medical electronic devices, confirm with the medical electronic device maker or dealer for the effect of the radio wave.
