Inspection and Cleaning
This subsection describes how to determine whether the Live Controller needs
cleaning, and how to do the cleaning. Inspection and cleaning are preventive
maintenance procedures. When done regularly, preventive maintenance may
prevent Live Controller malfunctions and enhance reliability.
Preventive maintenance consists of visually inspecting and cleaning the Live
Controller, and using general care when operating it.
How often you do periodic maintenance depends on the severity of the environ-
ment in which the Live Controller operates.
Inspect and clean the Live Controller as operating conditions require. The
accumulation of dirt on components inside can cause them to overheat and break
down. (Dirt acts as an insulating blanket, preventing efficient heat dissipation.)
Dirt can also provide an electrical conduction path that can cause instrument
failure, especially under high-humidity conditions.
WARNING. To avoid personal injury or death due to electric shock, unplug the
power cord from the line voltage source before cleaning the Live Controller.
CAUTION. To prevent damaging the plastics used in the Live Controller, do not
use chemical cleaning agents. Use only deionized water when cleaning the keys,
lever or knob. Use a 75% isopropyl alcohol solution as a cleaner, and rinse with
deionized water. Before using any other type of cleaner, consult your Grass
Valley Group Service Center or representative.
To prevent damaging Live Controller components, do not use high-pressure
compressed air when cleaning dust from the interior of the Live Controller.
(High pressure air can cause electrostatic discharge.) Instead, use low pressure
compressed air (about 9 psi).
