OPERATIONAL HINTS
• The transmitter's service distance is 3 – 100 m. When the transmitter 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.
• Confirm the good line of sight between the transmitter and the receiver. Do not place the large obstructions
(ex. Concrete walls or large metal obstructions) between the transmitter and the receiver. In addition keep
the receiver away from the metallic beams and obstructions as these can adversely affect the antenna pick-
up pattern and induce the interference.
• 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.
• Hold the microphone within 20cm from the sound source. Move the microphone closer for a warmer sound
increased. And do not cover the grille with hand.
• Keep your mouth 15 – 20 cm away from the lavalier microphone for the best possible sound reproduction. In
case of the Omni-directional response, it will pick up sounds from all directions. It is better that the
microphone is placed closer to the sound source. Take care not to bring your mouth too close to the
microphone (within 5 cm) as this impairs speech clarity if you speak loudly.
• In case of the headset microphone, 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.
