2. GENERAL DESCRIPTION
The WM-4200 Wireless Microphone employs a dynamic microphone element with high input handing capacity
and is suitable for vocal applications and other professional uses.
3. FEATURES
• One frequency can be selected from 64 operating frequencies (4 banks x 16 channels) of 690 – 865 MHz.
• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient
temperature or voltage fluctuation.
• Dynamic range of over 110 dB can be obtained when the unit is used in combination with the WT-4800.
• Audio level control adjusts the microphone sensitivity.
• Power switch features a lock mechanism to protect accidental power-off.
• Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery level
remarkably decreases.
4. HANDLING PRECAUTIONS
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as
doing so may result in unit failure.
• Never open nor remove the unit case to modify the unit. Refer all servicing to your nearest TOA dealer.
• Take care not to drop the unit onto the floor nor bump it against a hard object as the unit could fail.
• Do not place the unit in locations of high temperature (ex. in a car parked in summer) or high humidity as the
unit could fail.
• Do not use the unit in locations where it is exposed to seawater.
• To clean, use a dry cloth. When the unit gets very dirty, wipe lightly with a cloth damped in a dilute neutral
cleanser, then wipe with a dry cloth. Never use benzine, thinner, or chemically-treated cleaning towel.
• Avoid using a mobile telephone near the wireless microphone in use. Noise could be picked up.
