Changing the microphone and windshield
To change the microphone, take off the windshield first (see chapter 3.3). Now, you need to unfasten
the microphone from the mounting head. Unscrew the microphone in a counter-clockwise direction.
To attach a new microphone, screw the microphone on clockwise until it fits tightly.
It is critical to make
sure the sensor is tightly fitted
. Use the NM104I1Z wrench but be gently and be aware not to break or strip
the thread.
Note: Note, when the microphone is changed, the new microphone serial number is
automatically stored into the SV 104A internal memory.
In case the windshield is destroyed/lost by any accident, or it gets too dirty to afford the microphone the
best protection then
SVANTEK
offers
SA 122A_3
three pcs per pack (windscreens for
