112. GENERAL DESCRIPTIONThe wireless microphone WM-3310 is of lavalier type, while the WM-3310H is of headsettype, and all are designed for use on VHF band.The WM-3310/-3310H accommodate the supplied microphone unit or headset with a cardioid pick-uppattern and are suitable for speech reinforcement applications. The built-in circuitry is so designed to minimizethe influence from ambient noise.3. FEATURES• One frequency can be selected from 6 operating frequencies of 6 frequencies of 169 – 216 MHz.•An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambienttemperature or voltage fluctuation. • Audio level control adjusts the microphone sensitivity.•Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery levelremarkably decreases.• Compact size and high reliability4. HANDLING PRECAUTIONS •Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, asdoing 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 theunit 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 neutralcleanser, 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.

136. BATTERY INSERTIONStep 1. Holding the microphone body, slidethe battery cover down to open it. Thebattery cover is designed not to beremoved from the body. Step 2. Insert the battery 6LR61 (Alkaline 9 V) according to the instructions attachedto the inside of the battery compartment. Pay attention to the correct polaritywhen inserting the battery.Step 3. Replace the battery cover.1Battery replacement•A brand-new battery will provide the power enough to operate the unitcontinuously for 10 hours.•As long as the battery has sufficient power for the microphone to functionproperly, the orange LED will light. When the orange LED starts to fade andthen flash, replace it with a new one.Power/Battery lamp(Orange LED)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 microphone 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.21Plug lockSecure the connectionwith the plug lock.
1410. CHANNEL NUMBER SETTING Step 1. Slide the battery cover down to open it.Step 2. Using the supplied screwdriver, set the Channel settingswitch 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 themicrophone signal. 2222222211. 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 downto open it. The battery cover is designed not to be removedfrom 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 rotatedclockwise, and decrease as rotated counterclockwise. 3Audio level control3Audio level control3Audio level control3Audio level control3Audio level control3Audio level control3Audio level control3Audio level control9. DISTANCE BETWEEN THE MICROPHONE AND THE MOUTH[Lavalier type version (WA-3310)]Keep your mouth 15-20 cm away from the microphone for the best possible sound reproduction. Take carenot to bring your mouth too close to the microphone (within 5 cm) as this impairs speech clarity if you speakloudly. [Headset type version (WA-3310H)]By adjusting the gooseneck, locate the microphone with the supplied windscreen in front of your mouth, andposition it 3-5 cm away from your mouth for the best sound reproduction. When the microphone is too close toyour mouth or you speak too loud, speech clarity will be impaired, making it hard for the audience to hearannouncements. 8. OPERATIONAL HINTS•The microphone's service distance is 3 – 100 m. When the microphone user moves in a facility, signaldropouts (momentary losses of signal reception) may be encountered. These dropouts are caused by thebuilding'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 samefrequency. In such cases, change the operating frequency of your system. (As to dealing with theinterference, refer to the operating instructions of the wireless tuner.)•Should you have any questions regarding the use or availability of TOA wireless products, please contactyour local TOA dealer.

LICENSE REQUIREMENTOperation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received,including interference that may cause undesired operation.Step 4. Adjust the corresponding tuner's volume control so that its knob points to the 2 o'clock position. If thetuner's AF PEAK indicator remains lit, readjust the microphone's audio level control to the positionthat causes the indicator to flash when the tuner output level reaches its peak. The AF PEAK indicatorlights when the output level reaches the point of about 3 dB below the clipping level.NoteThe 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 volumecontrol setting. Step 5. Replace the battery cover.
