9. DISTANCE BETWEEN THE MICROPHONE AND THE MOUTH
[Lavalier type version (WA-4310)]
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-4310A, WA-4310H)]
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.
8. OPERATIONAL HINTS
• The microphone's service distance is 3 – 120 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.)
