DLAWM-5270Wireless Microphone

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 MICROPHONE INSTRUCTION MANUAL • 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. · 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 for compliance 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 messages regarded as very important precautions are included. • We also recommend you keep this instruction manual handy for future reference. 2. GENERAL DESCRIPTION The 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 MHz for USA/Canada). • An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient temperature 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 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. 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 FCC ID: DLAWM-5270 IC: 1599A-WM5270 6. REPLACING THE BATTERY Step 1.Hold down the power switch for one second or more to turn off the power. 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. 2 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. • 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.
