2. GENERAL DESCRIPTION
The TOA's WM-5320 is a lapel wireless microphone, and the WM-5320A and WM-5320H are headset
wireless microphones, which are all designed for speech use.
The WM-5320 employs an omni-directional electret condenser microphone element, while the WM-5320A and
WM-5320H employ unidirectional electret condenser microphone elements.
The WM-5320A differs from the WM-5320H in that the WM-5320A features sweat-proof design and is
supplied with a waist pouch.
3. FEATURES
• One frequency can be selected from 64 frequencies (16 channels x 4 banks) of 636 – 698 MHz.
• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient
temperature or voltage fluctuation.
• Audio level control adjusts the microphone sensitivity.
• Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the battery
level remarkably decreases.
• Compact and high reliability
• Sweat-proof handset with an adjustable fixing band is exclusively designed for use by aerobics instructors.
(WM-5320A only)

• 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.
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 an ill-ventilated car 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.

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.
