We also recommend that you keep this manual handy for future reference.
1. SAFETY PRECAUTIONS
2. GENERAL DESCRIPTION
• 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.
The wireless microphone WM-3310 is of lavalier
type, while the WM-3310H is of headset type, and all
are designed for use on VHF band.
The WM-3310/-3310H 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.
WARNING
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
• 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.
CAUTION
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
• 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.
3. FEATURES
• One frequency can be selected from 6 operating
frequencies of 169 – 216 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
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.

Battery replacement
• A brand-new battery will provide the power enough to operate the unit
continuously for 10 hours.
• As long as the battery has sufficient power for the microphone to function
properly, the orange LED will light. When the orange LED starts to fade and
then flash, replace it with a new one.

7. OPERATION
Step 1. Plug the microphone's plug into the input connector
as illustrated.
Step 2. Make sure that the receiver and the wireless
microphone are of the same channel (frequency).
Step 3. If they are not identical in channel, you have to
adjust the channel switch.
Step 4. Press the power ON/OFF switch to turn on the
microphone.
The orange LED indicates the circuit is active.
Step 5. Make sure to press the ON/OFF switch again to
turn off the microphone after using.

8. OPERATIONAL HINTS
• The microphone's service distance is 3 – 100 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.
• Dangle the antenna freely. If wound around the unit or tied into bundles, sufficient service distance cannot
be obtained.
• 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.
9. DISTANCE BETWEEN THE MICROPHONE AND THE MOUTH
[Lavalier type version (WM-3310)]
Keep your mouth 15 – 20 cm away from the microphone for the best possible sound reproduction. Take care not
to bring your mouth too close to the microphone (within 5 cm) as this impairs speech clarity if you speak loudly.
[Headset type version (WM-3310H)]
By adjusting the gooseneck, locate the microphone with the supplied windscreen in front of your mouth, and
position it 3-5 cm away from your mouth for the best sound reproduction. When the microphone is too close to
your mouth or you speak too loud, speech clarity will be impaired, making it hard for the audience to hear
announcements.

Step 2. Using the supplied screwdriver, set the channel
selector switch pointer to the desired channel number.
Step 3. Replace the battery cover.
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.
11. AUDIO LEVEL ADJUSTMENT (SENSITIVITY CONTROL)
To change the factory-preset level, follow the procedures below.
Step 1. Holding the microphone body, slide the battery cover
down to open it. The battery cover is designed not to be
removed from the body.

Step 2. Switch on the power of the tuner and microphone.

Step 3. Adjust the audio level control using the supplied
screwdriver. The microphone sensitivity increases as the
control is rotated clockwise, and decrease as rotated
counterclockwise.
Step 4. Adjust the corresponding tuner's volume control so that its knob points to the 2 o'clock position. If the
tuner's AF PEAK indicator remains lit, readjust the microphone's audio level control to the position
that causes the indicator to flash when the tuner output level reaches its peak. The AF PEAK indicator
lights when the output level reaches the point of about 3 dB below the clipping level.
Note
The AF PEAK indicator operates in response to the volume control position.
However, the AF LEVEL indicator (on the WT-3810) indicates the level regardless of the volume
control setting.
Step 5. Replace the battery cover.
