9. 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.)
• Should you have any questions regarding the use or availability of TOA wireless products, please contact
your local TOA dealer.
10. DISTANCE BETWEEN THE MICROPHONE AND THE MOUTH
[Lapel Wireless Microphone WM-5320]
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 Wireless Microphones WM-5320A and WM-5320H]
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.
11. AUDIO LEVEL ADJUSTMENT (SENSITIVITY CONTROL)
To change the factory-preset level, follow the procedures below.
Step 1. Holding the microphone body, open the rubber cap as
illustrated.
Step 2. Switch on the power of the tuner and microphone.
Step 3. Adjust the audio level control using the supplied
screwdriver. The microphone sensitivity increases as the
control is rotated clockwise, and decreases as rotated
counterclockwise.
Step 4. Adjust the corresponding tuner's volume control so that
its knob points to the 2 o'clock position. If the tuner's AF
peak lamp remains lit, readjust the microphone's audio level control to the position that causes the
indicator to flash when the tuner output level reaches its peak. The AF peak lamp lights when the
output level reaches the point of about 3 dB below the clipping level.
Note
The AF peak lamp operates in response to the volume control position.
However, the AF level lamp on the LCD (on the WT-5800/5805) indicates the level regardless of the
volume control setting.
Step 5. Replace the battery cover.
