4. HINTS FOR BETTER USE
• Positioning Orientation
Position the unit with its front (speaker side) oriented toward the listeners to avoid feedback. If feedback
occurs, move the microphone away from the unit or decrease the output volume.
• Location
Sound from the speaker can be heard more clearly by positioning the unit above floor level, such as on a desk.
The distance between the meeting amplifier and the wireless microphone can also be made longer.
• Dead Point
As the wireless microphone user moves, a point where signal reception is abruptly and temporarily lost may
be encountered due to radio signal reflection or interference. To avoid such a dead point, keep the unit away
from walls or desks, or move the unit location approximately 1 – 2 m in any direction.
• Radio Signal Source Interference
Keep the unit away from fluorescent lamps or computers, which can generate high frequency noise, as radio
interference could result, shortening the wireless microphone's transmission distance.
• Wireless Microphone Distance
Keep the unit at least 3 m away from the wireless microphone. If the distance is shorter than 3 m, feedback
noise can be generated, resulting in radio interference.
• Cleaning
When cleaning, be sure to switch off the power, then wipe with a dry cloth. If the unit should become extremely
dirty over time, use a cloth dampened in a neutral detergent. Never use volatile liquids such as benzene or
thinner, because they can deform or discolor the unit's case.
