The MENU button steps through the four primary win-

ous options within each display selection and to set the
operating frequency of the receiver.

Rear Panel Features

XLR Audio Output Jack

This is a standard XLR configuration with pin 2 "posi-
tive" with reference to hand-held and plug-on transmit-
ters. With lavaliere microphones and belt-pack trans-
mitters, however, phase will vary with different types of
microphones (2-wire vs. 3-wire for example). The audio
output is balanced but not floating, so an unbalanced
signal is available using pin 1 as ground and pin 2 as
signal, leaving pin 3 open.

Power Input Jack

The power input jack can accept 10-18 VDC - the
center pin is positive and sleeve is ground. The input
is diode protected to prevent damage if the power is
applied with reversed polarity, but the unit will not work
until the reversed polarity condition is fixed. The small
Velcro strip can be used as a strain relief and retainer
on the power cable to avoid accidental disconnection.
Attach the adhesive strip side to the side of the receiver
or mount with the opening end of the strip up - place the
cable in the strip and secure.
