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. 

• Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the battery

level remarkably decreases.

• 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.
