System Checkout and Balancing
The system checkout of the A300 Audio Greeter can be completed by following the steps below:
1. Plug the +12VDC power supply into an electrical outlet and connect power plug into J5.
2. Turn the power switch on. Make sure the A300 completes its boot-up cycle. (Each LED will flash once, then the unit
will beep 3 times).
3. Press the MODE button until the RECORD light comes on. Record a message in all four message locations.
4. Press the MODE button until the MONITOR light comes on. Play each message by pressing the MESSAGE
SELECT number button and pressing PLAY NOW button. Also press the MONITOR VOLUME arrow buttons to
change the volume of the messages.
5. Select all the messages by pressing all the MESSAGE SELECT number buttons. Test the ALTERNATE
MESSAGES function by pressing the ALTERNATE MESSAGES ON button and the PLAY NOW button several
times. Verify that each time the PLAY NOW button is pressed that the next message is played until the first message
is played again. While a message is playing press the CANCEL button to verify that the message stops.
6. Verify that the vehicle detector is operating properly by having a vehicle drive into the vehicle detection area. The
VEHICLE LED should illuminate when the vehicle is detected, and go off when the vehicle leaves.
7. Press the MODE button until the PLAY light comes on to test messages at the menu sign. Select all the messages by
pressing all the MESSAGE SELECT number buttons.
8. Stand near the outside menu sign speaker and have a vehicle drive into the vehicle detection area to verify that all the
messages play at the speaker. Also have someone inside the building press the PLAY NOW and CANCEL buttons to
verify their operation.
9. Have the person inside press the MESSAGE DELAY ON button. Drive the vehicle through the vehicle detection area
and verify that the message is delayed by the correct preset delay time.
10. Adjust potentiometer MENU SPKR VOL, located on the left side of the A300, to control the menu sign message
volume. Also press the DAY/NIGHT button while playing a message to verify the night-time menu sign message
volume.
11. For 3M C760/C960 Systems only. Adjust potentiometer AUDIO OUT to set the message volume in the
headset/intercom.
Note:
Potentiometer AUDIO OUT is only used to set the message volume for the convenience of the headset/intercom
operator. Therefore, to reduce operator fatigue, adjust AUDIO OUT to set the message volume so it is barely audible
in the headset/intercom.
12. Attach the Wire Cover plate using the hardware supplied.
13. Attach the Operating Instructions Placard to a nearby wall, if possible, using an appropriate mounting method.
