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 oor 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oorroomstosuppressinuence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afxmetallabeltotheantennaelement,asdoing
