Close the control unit door.
Note:
The Federal Communications
Commission requires that sig-
nals be limited in loudness, if
your music on hold sounds
distorted, your music input
may be too loud. Turn the vol-
ume down on your music
source. If this does not cor-
rect the problem, call the
HELP number listed in the Us-
er’s Guide or Service Manual.
