Notice for the customers in Canada
For the wireless transceiver (EZW-RT10) This device complies with RSS-Gen of IC Rules. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

Features

The AIR-SA15R is an S-AIR compatible product. It is also called the S-AIR sub unit. Connecting this unit with an S-AIR main unit using S-AIR technology, you can use each unit in a remote location. For example, you can install this unit in the bedroom, and then install an S-AIR main unit in the living room. You can then listen to the music from the S-AIR main unit located in the living room by controlling this unit.

Getting Started

Connect the unit and S-AIR main unit to listen to sound from the S-AIR main unit.

Wireless Speaker System

Operating Instructions
This equipment complies with IC radiation exposure limits set forth for uncontrolled equipment and meets the RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment should be installed and operated with at least 20cm and more between the radiator and persons body (excluding extremities: hands, wrists, feet and ankles).

Precautions

Notes on use of the S-AIR product
As the S-AIR product transmits sound by radio waves, sound may skip when radio waves are obstructed. This is a characteristic of radio waves and is not a malfunction. As the S-AIR product transmits sound by radio waves, equipment that generates electromagnetic energy, such as a microwave oven, may interfere with sound transmission. As the S-AIR product uses the radio waves that share the same frequency as other wireless systems, such as wireless LAN or Bluetooth devices, interference or poor transmission may result. In this case, take the following steps: Do not install the S-AIR product near other wireless systems. Do not use the S-AIR product and the other wireless systems at the same time. The transmission distance differs depending on the usage environment. Find a location where transmission between the unit and the S-AIR main unit is most effective, and install the unit and the SAIR main unit there.

Recent times have seen the rapid spread of DVD media, Digital Broadcasting, and other high-quality media. To ensure that the subtle nuances of these highquality media are transmitted with no deterioration, Sony has developed a technology called S-AIR for the radio transmission of digital audio signals with no compression, and has incorporated this technology into the EZW-RT10. This technology transfers digital audio signals with no compression using the 2.4 GHz band range of ISM band (Industrial, Scientific, and Medical band), such as wireless LANs and Bluetooth applications.
It is easy to set the same S-AIR ID for the unit and SAIR main unit to establish the connection. However, if a neighbor has an S-AIR main unit with the same S-AIR ID as your S-AIR main unit, you may be able to hear the audio transmitted from your neighbors S-AIR main unit on your system. To prevent this, you can identify the unit with a specific S-AIR main unit by performing the pairing operation.

Before pairing

The connection is established by the S-AIR ID (example).
Your system Neighboring system Notes on using the remote
