and position the top of the microphone just below
the collarbone. NOTE: Positioning of the REDMIKE is
critical for proper volume adjustment.
4. While speaking in a normal voice
slowly increase the volume of the
corresponding channel on the 850iR
until your voice is barely audible.
REMEMBER:
This equipment
supplements the user’s voice so they are able to speak in a conversational tone.
Having the volume set too high will result in feedback and listener fatigue.

Fine-tuning the audio is accomplished by
making minor adjustments to the 8-Band
Graphic Equalizer on the back panel of
the 850iR.
6. If a second REDMIKE was
purchased, repeat steps 2-4.
NOTE: Each REDMIKE has its
channel pre-set to either A or
B. No further adjustment is
necessary.
See page 13 for hints on setting the EQ.
