III. ROUTINE HS400 OPERATION
HS400 control buttons are touch-sensitive. Use your fingertip, not your fingernail, when
touching the buttons.
The HS400 can be operated in push-to-talk (PTT), hands-free (HF) or auto hands-free
(AHF) modes.
In the push-to-talk mode, you must press and hold a button 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 hands-free and auto hands-free modes, you can transmit and receive communication
at the same time, as in a normal telephone conversation. The hands-free and auto hands-
free modes are both examples of “full-duplex” operation. In the HF mode, transmission and
reception are activated by touching and releasing a button. In the AHF mode, transmission
and reception are activated automatically when a customer drives into the drive-thru lane.
