•An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient temperature or voltage fluctuation.

•Audio level control adjusts the microphone sensitivity.

•Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery level remarkably decreases.

•Compact size and high reliability

•Sweat-proof handset with an adjustable fixing band is exclusively designed for use by aerobics instructors. (WM-4310A only)
