Portable 900 MHz Wireless Speaker System

Thank you for purchasing the RCA Portable 900 MHz Wireless Speaker System. Your system gives you high-quality stereo sound in the 900 MHz band to almost anywhere in or around your home. Your Speaker System's three selectable channels, PLL (Phase-Locked Loop) circuitry and built-in antenna give you precise tuning, so you can enjoy your favorite music while you exercise or work around your yard or house — up to 300 feet away from your stereo.

Your system has compander circuitry for optimum dynamic range and noise reduction, a 10-watt RMS amplifier in each speaker, a 2-way speaker design with 5" woofer and 1" dome tweeter. It has true stereo operation with frequency ranges from 50Hz to 20KHz (6dB bandwidth), which will offer you the best sound. There is no pilot tone spill over in this system, and this improves your sound quality. Also there is Automatic Level Control for

audio input to RF transmitter for optimum FM deviation adjustment (plug and play, no user adjustment is required)

Installing the Transmitter

Choosing a Location

In order to achieve the best performance, position the transmitter as far as possible from other electronic devices such as TVs, receivers, or VCRs. Radio interference from these devices could affect your system's performance.

Position the transmitter away from large metal objects, as these could block your transmitter's signals. Try several locations for the transmitter. Select the location that provides the best performance. Set up the transmitter to send a wireless signal to the speakers.

Connecting to AC Power

Connect the transmitter to AC power with the supplied 12V, 250mA AC adapter. Plug the supplied AC adapter's barrel plug into the transmitter's adapter into a standard AC outlet.

Cautions:

• You must use a Class 2 power source that supplies 12 volts DC and delivers at least 250mA. Its center tip must be set to positive and its plug must fit the transmitter's adapter meets these specifications. Using an adapter that does not meet these specifications will damage the transmitter or the adapter.

• Always connect the AC adapter to the transmitter before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the transmitter.

at the other end of the patch cord directly to the audio source's corresponding left (white) and right (red) audio jacks.

For normal stereo use, set STEREO/MONO, on the back of the transmitter, to

STEREO.

If you are using a monaural system, set

STEREO/MONO to MONO.

If you are using your audio source's stereo headphone jack, connect the patch cord's

white and red plugs to the white and red phono jacks on the phono side of

the
