The AJ-40 plays a hiss that keeps changing in pitch and volume. Microphones close by record that hiss instead of clear speech.
Turn it on, set the level with the push buttons (start around halfway) and place it near where people are talking. One unit covers up to 200 square feet.
The built-in battery runs 3 to 6 hours depending on volume and recharges in under 2 hours. Recharge with any computer, phone, wall or car charger.
Use it to keep your own conversations private in your office, meeting room, car or home. It is a sound masker, not a radio device, so it does not affect phones or wireless signals.
