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 “half-duplex” or “full-duplex” modes.

In the half-duplex mode, you must press and hold a button while talking to a customer,

and release the button to hear the customer’s response. The HS400

push-to-talk (PTT) mode is an example of half-duplex operation.

In the full-duplex mode, you can transmit and receive communication at the same time, as

in a normal telephone conversation. The HS400 hands-free (HF) and auto hands-free (AHF)

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.
