Inspection and Cleaning describes how to inspect for dirt and damage. It also
describes how to clean the exterior and interior of the RTX100B. Inspection and
cleaning are done as preventive maintenance. Preventive maintenance, when
done regularly, may prevent the RTX100B from malfunctioning and enhance its
reliability.
Preventive maintenance consists of visually inspecting and cleaning the
RTX100B and using general care when operating it.
How often preventative maintenance should be performed depends on the
severity of the environment in which the RTX100B is used. A proper time to
perform preventive maintenance is just before the RTX100B adjustment.
The cabinet helps keep dust out of the RTX100B, and is needed to meet EMI and
cooling requirements. The cabinet should be in place when operating the
RTX100B. The front cover protects the front panel and display from dust and
damage. Install the front cover when storing or transporting the RTX100B.
Inspect and clean the RTX100B as often as operating conditions require. The
collection of dirt on components inside can cause them to overheat and break
down. (Dirt acts like an insulating blanket, preventing efficient heat dissipation.)
Dirt also provides an electrical conduction path that could cause an RTX100B
failure, especially under high-humidity conditions.
CAUTION. Avoid the use of chemical cleaning agents that might damage the
plastics used in this RTX100B. Use only deionized water when cleaning the
menu buttons or front-panel buttons. Use an ethyl alcohol solution as a cleaner
and rinse with deionized water.
Inspection — Exterior. Inspect the outside of the RTX100B for damage, wear, and
missing parts, using Table 5-1 as a guide. An RTX100B that appears to have
been dropped or otherwise abused should be checked thoroughly to verify correct
operation and performance. Immediately repair defects that could cause personal
injury or lead to further damage to the RTX100B.
