ADJUSTING EAR MONITOR VOLUME
Listen for your program source, and adjust receiver volume to a comfortable listening level. The E03
receiver is capable of providing listening levels loud enough to be heard in use with a rock band. Many
bands use on stage loudness levels that with repeated exposure could pose a threat to their hearing.
Therefore, it is very important that the E03 be used at a reasonable and comfortable listening level.
NOTE: A slight hum may be heard if the receiver is used within six feet of the transmitter.
This is normal and does not affect performance.
TESTING RECEIVER RANGE
Wearing your receiver and earphones, walk around the stage area (and sound board and other areas
if crew members are to be equipped with E03 receivers) and listen for audio quality. In certain areas of the
room the audio may disappear or “drop out.” This is a normal occurrence whenever radio signals are trans-
mitted inside a building. If you step away from the “drop out” zone, the audio will return. If a drop out zone
is within the area of the stage or sound board(s), it is possible to eliminate the drop out zone by moving your
E03 transmitter as little as 12-18 inches in any direction. After you move the transmitter, “range walk” the
stage and other areas again to check for consistent reception.
