5. OPERATING THE REDMIKE
Once the REDMIKE is charged, follow these steps to set it up for use.
1. Turn the REDCAT power switch to 
the ON position. 
2. Remove the REDMIKE from the 
charging cradle and turn it on. The 
red IR LED (CH. A or CH. B) on 
the REDCAT will light to indicate a 
signal is being received.
3. Slip the REDMIKE with lanyard 
around the neck and position the 
top of the microphone just below 
the collarbone. 
4. Slowly increase the CH. A/B volume 
to the level shown in the diagram 
below. This is a typical level for a 
classroom.
5. While speaking in a normal voice, 
fine-tune the volume up or down. 
Proper volume level should be as 
follows:
•  Your voice should be clearly 
heard by another person on the 
other side of the room.
•  You should barely be able to 
hear your own voice.
•  There should not be any audio 
“feedback” or squealing 
outside of 2-3 feet (if there is, 
turn the volume down slightly).
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.
6. Once initial volume level is set, 
walk around the room and listen 
for audio dropout and overall 
audio quality. 
7. If further fine-tuning is required, 
audio equalization may be 
necessary. Please refer to the 
following page.
8. If a second REDMIKE was 
purchased, repeat steps 2-4.
