button to end communication with customer.
The headset can be operated in Hands-Free, Auto -Hands-Free or HandsFree-Off modes.
If your store does not have Hands-Free capability, you should
operate the System 500 according to section A.3. below in singlelane stores, or B.3. (page 9) in dual-lane stores.
If you are uncertain if your store has hands-free capability, refer
to section 4 on page 6.
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. In the Auto-Hands-Free mode, transmission and
reception are activated automatically when a customer drives into the
drive-thru lane. In the Hands-Free mode, transmission and reception
are activated by touching and releasing one of the A buttons on the
headset. In the Hands-Free-Off mode, you must touch and hold one of
the A buttons on the headset while speaking to the customer.
When a customer arrives in the drive-thru lane, you will hear a
single beep in the headset for single lanes and for Lane 1 in duallane operations, or a double beep for Lane 2. In dual-lane
operation, if you are communicating with a customer when another
customer arrives in the opposite lane, a higher pitch double beep
will sound in the headset to alert you of the second customer’s
presence. When the first customer leaves the speaker post, the same
higher pitch double beep will repeat in your headset every 4 seconds
until you touch the A1 or A2 button to communicate with the second
customer.
To communicate internally with another HS500 user, press and hold
the B button while talking. Release to listen.
