Troubleshooting Problem The iPhone does not recognize the unit when using AirPlay. The unit cannot connect to the Internet via a wireless router (access point). Wireless network is not found. Cause A multi-SSID supported router is used. The wireless router is turned off. The unit is placed too far from the wireless router. There is an obstacle between the unit and the wireless router. Wireless communication is interrupted by the electromagnetic waves emitted from a microwave oven or other wireless devices. Access to the network is restricted by the firewall settings of your wireless router. Solution The network separation function of the router may prevent the iPhone from accessing the unit. When connecting an iPhone, use SSID that can access the unit. Turn on the wireless router. Place the unit and the wireless router closer to each other. Remove the obstacles. When using the unit via wireless connection, place it away from devices emitting electromagnetic waves. Check the firewall setting of the wireless router. Bluetooth Problem Cannot make the unit pair with a Bluetooth device. Cannot make a Bluetooth connection. Cause The unit is turned off. The [Bluetooth] of the option settings is set to [Off]. Another Bluetooth device is connected. This unit and the device are too far apart. There is a device (microwave oven, wireless LAN, etc.) that outputs signals in the 2.4 GHz frequency band nearby. A Bluetooth adapter, etc., that you want to pair with this unit has a passkey other than "0000." The Bluetooth device does not support A2DP. The [Bluetooth] of the option settings is set to [Off]. Another Bluetooth device is connected. The Bluetooth function of the device is turned off. The pairing information has been deleted. This unit is not registered on the device's Bluetooth connection list. Solution Turn the unit on and perform the pairing (& P.25). Set it to [On]. Terminate current Bluetooth connection, and perform pairing with the new device. Pair the unit and device within a distance of 10 m (33 ft). Move this unit away from the device that is emitting radio-frequency signals. Use a device whose passkey is "0000." Perform pairing with a device which supports A2DP. Set it to [On]. Terminate current Bluetooth connection, then establish a Bluetooth with that device again. Turn on the Bluetooth function of the device. Delete the Bluetooth device's pairing information and perform pairing again. Perform pairing again (& P.25). 48 En
