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.
