XLR AUDIO OUTPUT JACK TO REPLACE THE BATTERIES
This is a standard XLR configuration with pin 2 “positive”
with reference to hand-held and plug-on transmitters.
With lavalier microphones and belt-pack transmitters,
however, phase will vary with different types of micro­
phones (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
condition is fixed. Strain relief to avoid accidental
disconnection can be provided with the included small
hook and loop strip. 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.
Lift and open the bottom battery door cover with your
thumb, rotate the door until it is perpendicular with the
case and allow the batteries to fall out of the compart­
ment into your hand. It is difficult to install a battery
backwards. Observe the large and small holes in the
battery contact pad before inserting new batteries.
Insert the contact end of the battery first, making sure
the contacts are aligned with the holes in the contact
pad, and then swing the door closed. You will feel it snap
into place when it is fully closed.
To open the battery
compartment door, push the
door up and away from the
case with your thumb, then
swing open.

CAUTION
Lithium batteries will expand and swell if allowed to go
into a deep discharge. Be sure to remove lithium batter­
ies as soon as possible after warnings. If lithium batter­
ies are allowed to fully discharge while still inside the
battery compartment, they will be very difficult to re­
move.
Stuck lithium batteries can be avoided by removing the
label wrapping around the battery before use. This will
allow the battery to swell but will still leave enough room
in the compartment for the battery to fall out normally.
