hi JLopez88,

I can't find anything on the Cadwell unit but the Natus unit is very similar. The service manual for the Natus says

"Turn OFF the system power before cleaning the
instrument. Do not permit solutions or sterilization
agents to seep into the electronic portions of the
system. Take special care around controls, connectors
and panel edges. Do not use any abrasive cleaners.
Remove any dust from the exterior of the system with
a soft brush or cloth. Use a brush to dislodge any dirt
on or around the connectors and panel edges. Remove
stubborn dirt with a soft cloth slightly dampened with a
mild detergent solution or cold sterilization agent.
When the monitor is on, the screen has a slight static
charge, which attracts dust. To remove any dust
accumulation, wipe the screen with a soft brush or lintfree
cloth. You may use an antistatic spray on the
screen to reduce static buildup."

Good Luck!
