General care
For optimum performance, follow these recommendations:
Protect your instrument from adverse weather conditions. It is not waterproof.
Do not store or leave your instrument where the liquid crystal display (LCD) will be exposed
to direct sunlight or high humidity for more than four hours.
The front and rear cases keep dust out of your instrument and must be in place during normal
operation.
To avoid damage to your instrument, do not expose them to any sprays, liquids, or solvents.
Inspection and cleaning
This section describes how to inspect for dirt and damage, and how to clean the exterior and interior
of your instrument. Inspecting and cleaning are done as preventative maintenance. When done
regularly, preventative maintenance, may prevent malfunctions and enhance reliability.
The collection of dirt on internal components can cause your instrument to overheat and fail. Dirt also
provides an electrical conduction path that could cause instrument failure, especially under high-
humidity conditions. Inspect your instrument as often as operating conditions require.
CAUTION. Avoid the use of chemical cleaning agents which might damage the plastics used your
AFG. Use only deionized water when cleaning the front panel buttons. Use an ethyl alcohol solution
as a cleaner and rinse with deionized water.
Exterior inspection
Inspect the outside of your AFG for damage, wear, and missing parts, using the following checklist as
a guide. If your AFG appears to have been dropped or damaged, it should be checked thoroughly to
verify correct operation and performance. Immediately repair defects that could cause personal injury
or cause further damage to your AFG.
