Listen SQ™

We are accustomed to listening to low noise, high fidelity audio (delivered via CD, DVD, etc.). FM radio systems, such as those made by Listen, have more inherent noise compared to most sound systems. To reduce noise of our systems, Listen now offers a noise reduction technology called Listen SQ™. Both the transmitter and receiver must have SQ™ on to achieve the desired results. SQ™ is now available on new Listen systems, including the system you received in this shipment. If you are planning to use this product with older Listen systems or equipment not manufactured by Listen, you should disable SQ™.

Your Listen equipment has been shipped to you with the SQ™ feature enabled. You may need to disable the SQ™ function for one or more of the following reasons:

1.You are using your new Listen system with older version Listen equipment that does not have the SQ™ function.

2.You are using your new Listen system with equipment supplied by other manufacturers.

3.You expect that end users may bring and use their own receivers that don’t have the SQ™ function.

SQ™ Summary

• Improves noise performance by at least 20dB

• SQ™ is NOT compatible with older version Listen products

• SQ™ is NOT compatible with other manufacturers’ products

• SQ™ is NOT squelch

• To work properly, SQ™ must be enabled for both the transmitter and receivers

• SQ™ can be disabled to permit operation with older Listen products or other manufacturers’ products
