(as ofJune 2009)U.S. and Canadian fields: Infrared Receiver (WX-LR100), Infrared Receiver/Amplifier (WX-LA20, WX-LA50), Infrared Wireless Powered Speaker (WX-LP100)European and Asian fields: Infrared Receiver (WX-LR100/A, WX-LR100/B), Infrared Receiver/Amplifier (WX-LA20, WX-LA50), Infrared Wireless Powered Speaker (WX-LP100)• The use of a PLL synthesized system allows selecting one out of four available frequencies(1 of 4 channels).• The transmitting channel is changed by operating a channel selector.• The product can derive its power supply from a rechargeable battery (AA size), a dry cell(AA/LR6 size) or a charger (option). (☞ page 21)• Connection of the charger (WX-LZ150) to this product allows our nickel metal hydride bat-tery to be charged.• Connecting an external microphone or any other external sound source to the product’smicrophone input terminal will allow you to transmit audio to the receiver.Caution about interception of transmissionThis product is a wireless system using infrared, and the transmission and reception of audiosignals are possible within the range that the infrared can reach.If any third party is within the range of the infrared, the audio signals can reach anywhereunless there are obstacles (such as walls). Therefore, if there is no action taken to preventinterception, malicious third parties may listen to content by intercepting the infraredintentionally.In order to handle this problem, you may set up infrared shielding materials such as shade cur-tains to close the transmitting and receiving range to reduce the interception.We would like you to fully understand the risks of using this product without taking precautionsfor interception, and we recommend you take your own preventative measures.If interception occurs due to negligence or the specifications of the infrared wireless, we shallnot take any responsibility for the damages that are caused thereby.
