Manual

Thank you for purchasing TOA's UHF Wireless Microphone. Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.WM-5270UHF WIRELESS MICROPHONEINSTRUCTION MANUAL• To prevent the electromagnetic wave from badly influencing medical equipment, make sure to switch off theunit'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 batteryleakage 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 fromleakage or explosion of the battery. · Do not short, disassemble, heat nor put the battery into a fire.· 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.• Attention should be drawn to the environmental aspects of battery disposal.CAUTION TO USER: Changes or modifications not expressly approved by the party responsible forcompliance could void the user's authority to operate the equipment.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 messagesregarded as very important precautions are included.• We also recommend you keep this instruction manual handy for future reference. 2. GENERAL DESCRIPTIONThe TOA's WM-5270 Wireless Microphone employs a dynamic microphone with high input handing capacity,and is suitable for vocal use.3. FEATURES•One frequency can be selected from 64 frequencies (16 channels x 4 banks) of 692 – 865 MHz (692 – 806 MHzfor USA/Canada).• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambienttemperature or voltage fluctuation. • The maximum input sound pressure can be set in the range of 130 dB SPL to 142 dB SPL by a PAD switch,permitting adaptation to wide range of input sound pressure.• Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the batterylevel 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 inconjunction with the optional WT-5800, WT-5805 or WT-5810 Wireless Tuner.Indicates a potentially hazardous situation which, if mishandled, couldresult in death or serious personal injury. WARNINGIndicates a potentially hazardous situation which, if mishandled, couldresult in moderate or minor personal injury, and/or property damage.CAUTIONFCC ID: DLAWM-5270IC: 1599A-WM5270
6. REPLACING THE BATTERYStep 1. Hold down the power switch for one second or more to turn off thepower.Step 2. Hold the microphone body and rotate the microphone gripcounterclockwise to remove it. Step 3. Insert an AA battery according to (+) and (–) indications on thebattery 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 forabout 10 hours.• When the battery capacity becomes low, the green LED of thePower/Battery lamps starts to dim, while the red LED to light. When onlythe 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.24. 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.• When using two or more wireless microphones, keep them at least 50 cm away from each other to avoidmalfunctions or noise. • Keep the wireless microphone at least 3 m away from the receiving antenna. Using the microphone in closeproximity to the antenna could result in malfunctions or noise. 5.

Using the screwdriver housed in the microphonebody, set the Channel selector switch pointer tothe desired channel number. Step 3. Replace the microphone grip. NoteMake sure that the wireless microphone is identical to thewireless tuner in the channel number. Should the microphone's setting differ from that of thetuner, the tuner does not receive the microphone signal. HBANK CHANNELLI/O0-6-12PAD4321456789ABCDEF0321Channel selector switch8. PAD SWITCH The input sensitivity can be decreased by 0 dB, –6 dB or –12 dB with the PAD switch.Select the appropriate level so that the output sound is not distorted when the volumecontrol knob of the tuner is set at the 2 o'clock position.If a loud voice distorts the output sound, decrease the sensitivity by shifting the PAD switchto the –6 dB or –12 dB position.Note: The PAD switch is factory-preset to 0 dB.The table at right shows the relationshipbetween the PAD switch positions and themaximum input levels.9. OPERATIONStep 1. Confirm that the wireless microphone and the wireless tuner are identical in the channel number. If not identical, turn off the power ON/OFF switch, then set the channel number to the same channelnumber as the tuner.Step 2. Hold down the power switch for one second or more to turn on the power.Then, confirm the green LED of the Power/Battery lamps will light.Step 3. Hold down the power switch for one second or more to turn off the power after use.10. OPERATIONAL HINTS• The microphone's service distance is 3 – 120 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. • If the output sound is distorted at the large volume level, use the microphone by shifting the PAD (inputsensitivity reduction) switch to the –6 dB or –12 dB position to decrease the sensitivity.• Attach the supplied rolling stopper as needed, preventing the microphone from rolling and dropping onto the floor.Rolling stopper(supplied)WM-5270PAD switch Maximum input level0 dB 130 dB SPL–6 dB 136 dB SPL–12 dB 142 dB SPLHBANK CHANNELLI/O0-6-12PAD4321456789ABCDEF0321Pad switch

NEW EMPHASIS CIRCUIT ON/OFF SWITCHThe WM-5270 incorporates an improved new Emphasis circuit that further suppresses noise.The Emphasis circuit can be switched to the new circuit (pre-compressor Emphasis) by setting the NewEmphasis circuit ON/OFF switch to ON (H position), and to the conventional circuit (post-compressorEmphasis) by setting the switch to OFF (L position).When using the WM-5270 with the switch set to ON, also reset the WT-5800 series tuner to a new circuit bymeans of the optional RW-4800 ROM Writer. So, further noise suppressed and clearer sound can be assured.The WM-5270 is compatible with the WT-4800 series turners when shipped from the factory (New Emphasiscircuit ON/OFF switch: OFF). Once the switch is set to ON, however, no more compatibility is ensured. The table below shows the compatibility between the Wireless Microphones and Tuners.WM-5270New Emphasis circuit ON/OFF switch: ON (H)WT-5800 seriesWT-4800 seriesPre-compressor (New Emphasis circuit)Post-compressor (Conventional Emphasis circuit)New Emphasis circuit ON/OFF switch: OFF (L): CompatibleWireless TunersWireless Microphones[Compatibility table]HLHL
