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.
