• To prevent the electromagnetic wave from badly influencing medical equipment, make sure to switch off the unit's power when placing it in close proximity to the medical equipment.
• When the unit is not in use for 10 days or more, be sure to take the battery out of the unit because battery leakage may cause personal injury or contamination of environment.
• Make sure to observe the following handling precautions so that a fire or personal injury does not result from leakage or explosion of the battery.
· Do not short, disassemble, heat nor put the
battery into a fire.
· Never charge batteries of the type which are not
rechargeable.
· Do not solder a battery directly.
· Be sure to use the specified type of battery.
· Note correct polarity (positive and negative

2. GENERAL DESCRIPTION
The wireless microphone WM-4310 is of lavalier type, while the WM-4310A and WM-4310H are of headset type, and all are designed for use on UHF band. The WM-4310/-4310A/-4310H accommodate the supplied microphone unit or headset with a cardioid pick-up pattern and are suitable for speech reinforcement applications. The built-in circuitry is so designed to minimize the influence from ambient noise. The WM-4310A differs from the WM-4310H in that the WM-4310A features sweat-proof design and is supplied with a waist pouch.
3. FEATURES
• One frequency can be selected from 16 operating frequencies of 16 frequencies of 690 – 865 MHz.
• 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)
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.
