5. HANDLING PRECAUTIONS
• Place the antenna where a talker having the wireless
microphone can directly see it.
• For the YW-7570, point the element’s shorter (narrow)
side toward the microphone talker.
• Install the antenna at the height of over 1.5 m (4.92 ft).
• Mount the unit on the floor microphone stand with 5/8"
(NS5/8) or 3/8" (W3/8) thread.
• Install the unit over 3 m (9.84 ft) away from the windows
when used in upper floor rooms to suppress influence of
external noise.
• Keep the unit over 3 m (9.84 ft) from the wireless
microphone. Otherwise, idle channels may operate or
interference may occur.
• When using a diversity tuner, keep over 5 m (16.4 ft)
apart between antennas.
• Install the unit over 30 cm (11.81") from metal objects or
electric wire to prevent decline in receiving sensitivity or
external noise problem.
• Ensure the connector connection. Improper connection
may cause decline in receiving sensitivity or external
noise problem.
• Use the low loss high frequency coaxial cable for the
antenna cable.
• Keep antenna wiring as short as possible (roughly 10 m
or 32.81 ft). To extend it more, use an antenna booster.
For the antenna booster, contact your TOA dealer.
• Bending or breaking the antenna element sharply
reduces receiving sensitivity. Handle it with care.
• Separately prepare the coaxial cable and BNC plug.
• Never place heavy objects on the YW-7520/YW-7570
during storage. It may be damaged.
• Never affix metal label to the antenna element, as doing
so may sharply reduces receiving sensitivity.
