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. WARNING Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury. CAUTION Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage. WARNING • 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 • 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. 10 • 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. 2. GENERAL DESCRIPTION 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. 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 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. 11 5. NOMENCLATURE [ Main unit ] [ Microphone unit ] (WM-3310 only) Power/Battery lamp (Orange LED) Power ON/OFF switch (push lock) Tie-clip attachment 32 23.5 This part rotates 360 . 102 142 Crip Plug lock 62 Audio level control Clip (Rotates 360 .) ø3.5 Channel select switch Windscreen Microphone [ Headset ] (WM-3310H only) Gooseneck Plug lock Windscreen ø3.5 Unit: mm 12 Microphone 6. BATTERY INSERTION 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. Insert the battery 6LR61 (Alkaline 9 V) according to the instructions attached to the inside of the battery compartment. Pay attention to the correct polarity when inserting the battery. Step 3. Replace the battery cover. 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. Power/Battery lamp (Orange LED) 7. OPERATION Step 1. Step 2. Step 3. Step 4. Plug the microphone's plug into the input connector as illustrated. Make sure that the receiver and the wireless microphone are of the same channel (frequency). If they are not identical in channel, you have to adjust the channel switch. 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. Plug lock Secure the connection with the plug lock. 13 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. • 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 (WA-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 (WA-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. 10. CHANNEL NUMBER SETTING Step 1. Slide the battery cover down to open it. Step 2. Using the supplied screwdriver, set the Channel setting 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. 14 Audio level control 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. 12. LICENSE REQUIREMENT Operation 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. 13.
