On placement  Place the receiver in a location with adequate ventilation to prevent heat buildup and prolong the life of the receiver.  Do not place the receiver near heat sources, or in a place subject to direct sunlight, excessive dust, or mechanical shock.  Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions.  Do not place the receiver near device such as a TV, VCR, or tape deck. (If the receiver is being used in combination with a TV, VCR, or tape deck, and is placed too close to that device, noise may result, and picture quality may suffer. This is especially likely when using an indoor antenna (aerial).)  Use caution when placing the receiver on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result. On operation Before connecting other device, be sure to turn off and unplug the receiver. On cleaning Clean the cabinet, panel, and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as alcohol or benzine. On BLUETOOTH communication Supported BLUETOOTH version and profiles Profile refers to a standard set of functions for various BLUETOOTH product features. See "BLUETOOTH section" in "Specifications" (page 40) for the BLUETOOTH version and profiles supported by this receiver. Effective communication range BLUETOOTH devices should be used within approximately 10 meters (33 feet) (unobstructed distance) of each other. The effective communication range may become shorter under the following conditions.  When a person, metal object, wall or other obstruction is between the devices with a BLUETOOTH connection.  Locations where a wireless LAN is installed.  Around microwave ovens that are in use.  Locations where other electromagnetic waves are generated. Effects of other devices BLUETOOTH devices and wireless LAN (IEEE 802.11b/g/n) device use the same frequency band (2.4 GHz). When using your BLUETOOTH device near a device with wireless LAN capability, electromagnetic interference may occur. This could result in lower data transfer rates, noise, or inability to connect. If this happens, try the following remedies:  Use this receiver at least 10 meters (33 feet) away from the wireless LAN device.  Turn off the power of the wireless LAN device when using your BLUETOOTH device within 10 meters (33 feet).  Install this receiver and BLUETOOTH device as closer to each other as possible. Effects on other devices The radio waves broadcast by this receiver may interfere with the operation of some medical devices. Since this interference may result in malfunction, always turn off the power on this receiver and BLUETOOTH device in the following locations:  In hospitals, on trains, in airplanes, at gas stations, and any place where flammable gasses may be present.  Near automatic doors or fire alarms. Note  This receiver supports security functions that comply with the BLUETOOTH specification to ensure secure connection during communication using BLUETOOTH technology. However, this security may be insufficient depending on the setting contents and other factors, so always be careful when performing communication using BLUETOOTH technology. 38GB
