Installation
Determining the Best Location for the A300 Audio Greeter
The A300 should be mounted on a vertical wall about 60 inches high. If the user must bend over a
countertop to reach the A300, then lower it to 50 inches so the user can speak directly into the on-board
microphone.
A quiet location is recommended if frequent voice recording is anticipated. A nearby manager's office or
other enclosed room would be ideal. Cable runs over 35 feet should be avoided to reduce signal
degradation.
Mounting Hardware (not supplied)
4 each, #8 screws
4 each, wall anchors
Mounting the A300 Audio Greeter
Before mounting the A300 to the wall, we recommend that you attach all the cables to the A300 while it
rests on a countertop or a chair near its mounting surface. This allows easy access to all jumpers and
controls with the cover open.
1.
Remove the A300 cover and unplug the switch panel ribbon cable from the main circuit board.
2. Place the A300 at the desired location 50" to 60" high. Mark the locations of the four holes in the
base onto the mounting surface.
3. Using appropriate mounting hardware (not supplied), attach the A300 base to the mounting surface.
4. Plug the ribbon cable into the main circuit board and attach the cover.
5. Clean the left-hand side of the cover with denatured alcohol and attach the external microphone
holder using the double-stick tape provided.
6. Attach the wire cover to the right side of the A300 using the screws provided.

Important
If it is necessary to operate the A300 with the cover removed while it is
mounted on a vertical wall, do not allow the cover to hang from the switch
panel ribbon cable. The cover may rest on the top edge of the base plate,
but make sure it doesn't fall off.
