Important
⿟ Too strong of a wireless output level may result in wireless interference.
Should that happen, lower the wireless output level (antenna field selection)
as much as is possible without causing the audio dropouts within the usage
area of the microphone.
⿟ When the antenna field selection is set to "Individual setting", the wireless
output level of each antenna can be set individually by the configuration/
maintenance PC. Refer to the support software manual for further details.
