TROUBLESHOOTING
& SERVICE
There are no user-serviceable parts inside the CP16/24. 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 CP16/24. 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 CP16/24. Do not spray electronic cleaners into the faders. Refer fader and switch maintenance to a service
technician.
Power Supply
If the CP16/24 will not turn on, check the external power supply. There is no fuse inside the CP1/24. 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 CP1/24 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 CP16/24 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. Do
not leave your CP16/24 for months without recharging it. Otherwise it will fall below the minimum voltage
(2Volts).
DMX512
If your fixtures are not responding to the CP16/24 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.
