J5
Set to designate the type of communication operation. Jumper pins 2 and 3 for standard

MENU PWR SEL – STD or DPLX
STD – applies power to outbound speaker amplifiers only when the TALK switch is pressed.
Note: for Standard (half–duplex) operation J6 MUST be placed in the STD position.
DPLX – applies power to outbound speaker amplifiers constantly. This will reduce the click
that is sometimes heard in duplex mode when the TALK button is pressed.

pressed. This decreases the chance of feedback when a headset is operating near the Monitor
Speaker in duplex mode.
