If you move your head in any direction other than horizontal rotation (such as moving your head up and down), the position of the sound might drift. If this occurs, press the WAZA-AIR unit’s up/down buttons simultaneously to reset the sound position to its default state.
Do not move the WAZA-AIR unit immediately (approximately one second) after turning on its power. Observing this will improve the accuracy of the gyro sensor built into the WAZA-AIR unit, making it less likely that the position will drift.
