>>Specifications >>Settings >>Listening Modes >>Playback Function LINKS Reference Information Radio Wave Caution This unit uses radio waves in the 2.4 GHz and 5 GHz frequency bands. There are nations and regions where the use of particular 5 GHz bands are prohibited outdoors, so do not use this unit outside in those places. 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. 64 • We assume no responsibility whatsoever for any error or damage of network environment or access device resulting from the use of this apparatus. Confirm with the provider or access device maker for more information. >>Basic Manual Troubleshooting | Appendix 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.
