Release the Activator button after the Status light on bottom
of control box begins to blink alternately red and green. The

Status Light Codes
The Status light will indicate what the CM4 is doing or what
mode it is in through a series of patterns of light flashes and
colors.
•
Normal Speaker Arms at Rest
- The "Status" light
will be a steady green.
•
Normal Run Motion of Speaker Arms
- The
"Status" light will flash in groups of 2 green followed
by a pause. In Normal Run Motion the speaker arms
have a variable speed. The speaker arms will start
slowly, accelerate to a faster speed, and then slow
down before coming to a stop.
•
Speaker Arms Obstructed
- The "Status" light will
flash in groups of 3 red followed by a pause. If the
speaker arms meet an obstruction they will sense
the obstruction, stop momentarily, and move in the
opposite direction for a few seconds. Remove the
obstruction and activate the speaker arms. They
should return to Normal Run Motion.
•
Speaker Arms Obstructed Both Ways
- The
"Status" light will flash in groups of 4 red followed by
a pause. Similar to "Speaker Arms Obstructed" but
speaker arms are prevented from moving in either
direction. Remove the obstruction and then activate
the speaker arms. They should return to Normal
Run Motion.
•
Power Loss
- The "Status" light will be solid red.
This indicates there has been a power loss. When
next activated the speaker arms will move at a slow
speed to their full closed position. If the speaker
arms are already retracted they will not move. The
"Status" light will return to solid green and the
speaker arms are ready for normal activation.
