TROUBLESHOOTING
& SERVICE
There are no user-serviceable parts inside the CP10xt. Any internal problem should be referred to a
qualified service technician.
Cleaning and Maintenance
As with any type of control console, keep drinks away from the CP10xt. If you need to clean the
front panel use a soft cloth. If necessary you can spray a small amount of glass cleaner on the cloth.
Do not spray directly on the CP10xt. Do not spray electronic cleaners into the faders. Refer fader and
switch maintenance to a service technician.
Power Supply
If the CP10xt will not turn on, check the external power supply. There is no fuse inside the CP10xt.
If the power supply should ever fail or become lost, only replace it with a U.L. or CE approved one
with the same voltage and power rating. The supply must provide 9 volts DC at 500 ma. The plug
has a 2.5mm hole with + voltage at the center.
Battery
The CP10xt uses a battery to maintain its memory. On power up the battery voltage is always
checked and the following message will be displayed if the battery voltage gets low.
WARNING, BATTERY
VOLTAGE BELOW 2V
If this happens, take the CP10xt to a qualified service center to have the battery replaced. The battery
can be replaced without losing the memory as long as it is carefully removed and replaced with the
power on. Nevertheless it is always a good idea to back up your memory to disk in case of any
possible memory loss.
DMX512
If your fixtures are not responding to the CP10xt check the dipswitches on the fixtures and refer to
their instructions to make sure they are set properly. Also check your cabling and connectors for
opens or shorts. Never connect the shield of your DMX cable to the shell of the connector. If you
are running long lines you need to terminate the last fixture in your DMX512 chain with a special
termination plug. If you don't have one you can make one by taking a 5 pin male XLR plug and
soldering a 120 ohm resistor between pins 2 and 3. Plug this into the unused signal thru connector on
the last fixture in your DMX512 chain.
