1. INTRODUCTION
The EOS HD Wireless Drive-thru Headset System is designed to deliver a clear drive-thru conversation
for Quick Service Restaurants (QSR) around the world.
The EOS Base Station and wireless headsets offer a clear conversation with customers in the drive-thru,
as well as fellow store employees using the headset’s B-Channel and a push of a button.
The Push-to-Talk feature is a basic headset operation that allows customer communication by holding a
headset button to talk and listen. The headset button is released to disconnect (see below).
Hands Free headset modes allow Order Takers to communicate with customers as they would in a phone
call by pressing a button once to talk to a customer at the menu. The headset automatically disconnects
when the customer drives away.
Note: Full Duplex must be installed to work in Hands Free mode (see below).
The Messaging System allows store owners the option to record pre-programmed greetings to customers
and detailed instructions and reminders to employees.
1.1 Full Duplex and Half Duplex Modes
1.1.1 Full Duplex:
In most Drive-Thru operations, a Menu board or Speaker Post consists of a Microphone to hear the
customer talk and a Speaker so the customer can listen.
When your Base Station is congured in Full Duplex mode, the Microphone and Speaker can transmit
audio at the same time like a telephone call. This is benecial for increasing the ability to understand a
customer and immediately respond without delay.
1.1.2 Half Duplex:
In this unique conguration, the Menu board or Speaker Post consists of only a single speaker.
This single speaker is used to both speak to and listen to the customer. But because there is only one
speaker, the Order Taker can’t speak and listen simultaneously as performed in Full Duplex mode.
Half Duplex works like a Walkie Talkie. To speak to the customer, press the headset A button. To listen
to a customer, release the A button.
Full Duplex is the fastest and most efcient form of Base Station communication, but some
circumstances may make it necessary to temporarily switch a base station to Half Duplex mode.
Should the microphone fail or be damaged, switching to Half Duplex allows the Order Taker to continue
taking orders until the microphone is repaired or replaced.
