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.
3. FEATURES
• One frequency can be selected from 16 operating frequencies of 692 – 865 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.
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.
• 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.
5. NOMENCLATURE
Power/Battery lamps
• A green LED lights as long as the battery
capacity is sufficient.
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.

6. BATTERY INSERTION
Step 1. Turn off the power switch.
Step 2. Hold the microphone body and rotate the microphone
grip counterclockwise to remove it.
Step 3. Insert an AA battery according to (+) and (–)
indications on the battery compartment.
Step 4. Replace the microphone grip by sliding and rotating it
clockwise.
Battery replacement
• A brand-new AA alkaline battery will continuously operate the unit for
about 10 hours.
• When the battery capacity becomes low, the green LED of the
Power/Battery lamps starts to dim, while the red LED to light.
When only the red LED lights, replace the battery with a new one. In this
condition, the unit transmits the remaining battery capacity information to
the tuner, causing the tuner's BATT indicator to light.
7. CHANNEL NUMBER SETTING
Step 1. Switch off the power. Rotate the microphone grip
counterclockwise to remove it.
Step 2. Using the supplied screwdriver, set the Channel setting
switch pointer to the desired channel number.
Step 3. Replace the microphone grip.
Note: Make sure that the wireless microphone is identical to
the wireless tuner in the channel number. Should the
microphone's setting differ from that of the tuner, the
tuner does not receive the microphone signal.
8. OPERATION
Step 1. Confirm that the wireless microphone and the wireless tuner are identical in the channel number. If
not identical, turn the power ON/OFF switch to the OFF position, then set the channel number to the
same channel number as the tuner.
Step 2. Turn the Power ON/OFF switch to the ON position. Then, confirm the green LED of the Power/Battery
lamps will light.
Step 3. Turn the Power ON/OFF switch to the OFF position after use.
9. OPERATIONAL HINTS
• The microphone's service distance is 3 – 120 m. When the microphone user moves in a facility, signal
dropouts (momentary losses of signal reception) may be encountered. These dropouts are caused by the
building's architectural designs or materials which block the travel of or reflect the radio signal. If this occurs,
the user needs to change locations for better signal reception.
• The proper operation of your wireless system may be interfered with by other system operating on the same
frequency. In such cases, change the operating frequency of your system. (As to dealing with the
interference, refer to the operating instructions of the wireless tuner.)
• Should you have any questions regarding the use or availability of TOA wireless products, please contact
your local TOA dealer.
