INSTRUCTION MANUAL

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully before use.

• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages

regarded as very important precautions are included.

• We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are used in this manual to prevent bodily injury and property

damage which could result from mishandling. Before operating your product, read this manual first and

understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

• 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 orientation) when inserting a battery in the unit.

· Avoid locations exposed to the direct sunlight, high temperature and high humidity when storing batteries.

CAUTION TO USER: Changes or modifications not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment.

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

CAUTION

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.

Power/Battery lamps

Power ON/OFF switch

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.

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.

5. NOMENCLATURE

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.

Green LEDRed LED

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

selector 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.

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.

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.
