Note: Do not close the chamber while it is on the post. In a closed position it may accidentally fall
off.
You may find it most convenient to position the FP40 at one edge of a table. If the client is seated
at the side of the table, the speaker can be rotated so that the correct angle for testing is very easily
achieved. See Figure 5.1.2.1.
Replace the test box/speaker when test is complete
• Remove the test box/speaker from the post and close it.
• The upright post is locked in place with a spring catch. Pull the catch outward to release the
post and return it to the horizontal position.
• Make sure all cables in the compartment are put away so they will not interfere with replacing
the test box.
• Set the test box back in the compartment, interlocking the back stop plates. As you do this,
guide the speaker wire so it stays to the side of the test box, not underneath it. Press down on
the front of the test box to snap the front catch in place.
