the toggle switch (see photo below) must be in the UP position(All) on BOTH
HEADSETS.
Two Scanner Input Operations

Intercom System Power
Inside the right ear cup of each headset is a 9-Volt battery that powers the
system. We always recommend that you always have a spare battery for
each headset on hand. We also recommend using alkaline batteries.
Cables - 3-Pin Umbilical Cable
You should route the cables where they are the most convenient for your
seating arrangement(these cables can plug into either side of the headset).
