While previous systems only “blanket out” or limit noise in higher sound frequencies, the revolutionary new SoundTracker system actually reduces noise while leaving the signal intact in the reception mode. In the transmission mode, it actually strengthens the signal, providing you with a significant reduction in noise on reception and transmission.

Difficulty: Moderately Easy

Instructions

Step 1

Push and release the ST button. A red LED is illuminated when SoundTrackeris turned on.

Tips & Warnings

Sound clarity is measured by the ratio of the signal level to the noise level. The higher the signal-to-noise ratio, the better the sound.
Make sure the power cord, antenna and microphone are connected to their proper connectors before starting.
