3. FEATURES
• One frequency can be selected from 64 frequencies (16 channels x 4 banks) of 636 – 698 MHz.
• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient
temperature or voltage fluctuation.
• Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the battery
level remarkably decreases.
• Operates on a single AA battery.
• Employs a built-in antenna.
• The state of battery consumption can be displayed on the tuner's indicator when the unit is used in
conjunction with the optional WT-5800, WT-5805 or WT-5810 Wireless Tuner.
2. GENERAL DESCRIPTION
The TOA's WM-5220 Wireless Microphone employs an electret condenser microphone element of high
sensitivity and intelligible sound quality, and is suitable for speech use.

When the battery capacity becomes low, the
green LED starts to dim, while the red LED to
light.
The microphone does not transmit the signal if
the channel selector switch is set to the empty
channel. In this case, the red LED and green
LED flash alternately.

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 an ill-ventilated car 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.
• When using two or more wireless microphones, keep them at least 50 cm away from each other to avoid
malfunctions or noise.
• Keep the wireless microphone at least 3 m away from the receiving antenna. Using the microphone in close
proximity to the antenna could result in malfunctions or noise.
