32. 7 Avoid handling modules in areas that have a floor or work surface covering capable of generating a static charge RTX100B ISDB T RF Signal Generator Service Manual Maintenance Inspection and Cleaning General Care Inspection and Cleaning Procedures A 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
33. 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 RTX100B ISDB T RF Signal Generator Service Manual 5 3 Maintenance Table 5 1 External inspection check list Item Cabinet front panel and cover Front panel buttons Connectors Accessories Cracks scratches deformations Repair or replace defective damaged hardware or gaskets module Missing damaged or loose Repair or replace missing or buttons defective buttons Broken shells cracked insulation Repair or replace defective and deformed contacts Dirt in modules Clear or wash out dirt connectors Missing items or parts of items bent pins broken or frayed cables and damaged connec tors Repair or replace damaged or missing items frayed cables and
