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.
