Place microphone and speakers in primary position.

Press and hold the
SETUP button
(Fig.
3d) on the receiver until the LCD
SETUP
indicator
(Fig. 3e) flashes 4 times and
SETUP stays lit — then release it.
NOTE: DO NOT TALk INTO yOUR SySTEM while in
Setup Mode.
Slowly raise the gain on the mixer
or amp until FBX
eliminates the first few feedback tones. With each new
feedback frequency, you will hear a short, quiet burst of
feedback that will disappear immediately as a filter is
set.
Pause raising the gain, and move the microphone to another area where it will be used.
Resume slowly raising the mixer gain, until FBX eliminates a few more feedback tones.
NOTE: When choosing microphone setup locations, try to anticipate likely areas where
the microphone will be positioned or moved to, or areas that may be especially prone to
feedback problems (e.g., under an overhead speaker).

Repeat until the
SETUP
indicator automatically turns off and
the
READy
indicator comes on.
NOTE:
You may quit
SETUP
mode at any time prior to its auto-
matic exit by simply pressing the
READy
button. This will enable
ready-to-operate status, but with fewer fixed FBX filters in place.
In the default factory setting, dynamic FBX filters will still be held
in reserve to catch and eliminate new feedback, regardless of
how or when SETUP mode is exited. (See
Section 14.3.2
for
details on the differences between fixed and dynamic FBX filters
and
Section 13.4.2.1
for instructions on changing the balance

of fixed versus dynamic FBX filters using the Remote Control Software or
Appendix D
for using the Dip Switches on
the back of the receiver).
3.2.2. FBX Bypass
The
ByPASS button
(Fig. 3d) bypasses only the FBX filters, and not
the additional signal processing (de-essing, compression and Mic
SuperModeling
TM
) available on the True Mobility
TM
Wireless Receiver.
This is a useful button that allows comparison of the sound quality
when FBX filters are in place, to the sound with no filters (the qual-
ity should be very similar).
Before pressing ByPASS, take care
to reduce your overall system gain so that you do not release
suppressed feedback!
