Description
The 3M™ Audio Greeter, Model A300, is a digital audio recorder that plays stored messages.
Up to four fifteen-second messages can be automatically triggered by a standard vehicle detector or manually started by
the control panel. Combinations of messages can be selected to play each time a vehicle enters the drive-thru area, or
several selected messages can play alternately.
Messages can be delayed up to 15 seconds after a vehicle is detected. A DAY/NIGHT button can lower the menu sign
speaker volume for night operation. When using a 3M Wireless Intercom System with a C921BA or C922 Base Station,
any message playing over the menu speaker will be cancelled when the order-taker presses the TALK button for at least
one second. A short tap of the TALK button will cancel only the alert tones, allowing the message to continue and be
heard in the headset/beltpack.
Messages can be recorded through the included external plug-in microphone, the internal microphone, or the auxiliary
input jack. Messages longer than 15 seconds can be recorded by selecting 2 or more message numbers. They will be
played back without a pause between them. Messages will be retained even if the A300 is turned off or is unplugged from
the AC outlet.
