• Reduce the input gain of the amplification system
• Position the microphone correctly and switch On
Roger NeckLoop
• Increase the Roger NeckLoop’s volume up to maximum
by pressing the volume button
• Increase the input gain of the amplification system
until acoustical feedback occurs
• Reduce the gain of the amplification system until
the feedback disappears
• Walk around the room and check that every position
is free of feedback
• Reset the Roger NeckLoop’s volume to the middle or
to the newly desired volume by pressing the volume button
Please note: the microphone gain of the classroom
