Headset
The headset can be operated in a push-to-talk (PTT), hands-free
(HF) or auto hands-free (AHF) mode.
In the PTT mode, you must press and hold one of the A buttons on
the headset while talking to a customer, and release the button
to hear the customer’s response. The push-to-talk mode is an
example of “ half-duplex ” operation.
In the HF and AHF modes, you can transmit and receive
communication at the same time, as in a normal telephone
conversation. In the HF mode, transmission and reception are
activated by touching and releasing one of the A buttons on the
headset. In the AHF mode, transmission and reception are
activated automatically when a customer drives into the drive-thru
lane. The hands-free and auto hands-free modes are both examples
of “ full-duplex ” operation.
