6. ROUTINE OPERATION
The EOS|HD can be operated in Hands-Free (HF), Auto-Hands-Free (AHF), B-channel
Hands-Free (BHF) or Push-To-Talk (PTT) modes.
A full-duplex system supports HF, AHF, BHF and PTT operation. In HF, AHF and
BHF operation, communication can be transmitted and received at the same time, as
in a normal telephone conversation. In the AHF mode, transmission and reception
are activated automatically when a customer drives into the drive-thru lane. In the
HF mode, transmission and reception are activated by touching and releasing the A1
or A2 button on the headset. In the PTT mode, the A1 or A2 button must be
pressed and held while the operator is talking to the customer. A half-duplex
system only supports the PTT mode, and the customer’s voice will not be heard
while the operator is pressing the A1 or A2 button.
In single lane operations, when a customer arrives in the drive-thru lane, you will
hear a single beep in the headset.
In dual-lane operations, when a customer arrives in a drive-thru lane, you will hear
one beep in the headset for Lane 1 and two beeps for Lane 2.
In dual-lane operation, if you are communicating with a customer in one lane when
another customer arrives in the other lane, you will hear a beep in the headset.
When the customer leaves the speaker post in the lane you are connected to, the
same beep will repeat in the headset every four seconds until you touch the A1 or
A2 button to communicate with the customer in the other lane.
Note: In dual-lane operations, if you have a Mode Switch and it is set to
“DEDICATED,” you will only hear beeps in the headset when a customer arrives in
the lane you are operating.
