7 Troubleshooting
The following table describes some of the common faults and how to rectify them
1. Microphone does not move up or
down
 Check that the DSP control signal is present logic
+2.5 to 12 Volts is required. It is important that the
DSP command signal is already present before
powering the system up.

Check DC supply is present (microphone will move
down and up when power is applied).

Check logic input cable connections between DSP
and DSP input port

Perform a reset by switching the dc supply off / on.
2. Microphone is picking up noise as it
is being raised / lowered.

This is normal. The microphone must be muted by
the DSP during the raising / lowering transitions.
3. Remote control not operating

Check if a battery is installed or the battery
insulator has been removed.

Check that there is clear view of transmitter to IR
sensor. The red LED on the IR sensor should light
each time a button is pressed.

Check remote red LED is showing when buttons are
pressed. Check or replace the remote battery.

Check IR sensor is connected to the Socket 1 (IR) on
the Main unit.

Check that the correct address code (if adjusting
height) for the CCRM 4000 has been input.
Cautions
1. Never grab hold of or stop the cable whilst the cable is being deployed. This may cause
jamming of the mechanism of the cable.
2. Do Not Exceed the Maximum carrying weight of 0.5lbs on the microphone cable. This will
cause the internal safety device to engage and stop the unit operating.
3. Do not add / extend the cable length. There is insufficient space to accommodate any extra
cable length.
4. Do not operate the mechanism in any other angle / position than specified.
IMPORTANT DO NOT ATTEMPT ANY DISSASEMBLY OF OTHER PARTS WITHOUT PRIOR WRITTEN
PERMISSION FROM CLOCKAUDIO.
