Caution
To avoid contaminating the flex cable contacts with oil from
your fingers, do not touch the contacts (or wear gloves).
Contaminated contacts may not cause immediate instrument
failure in controlled environments. Failures typically show up
when contaminated units are operated in humid areas.
