checked to ensure there are no unintended rough surfaces, sharp edges, or

protrusions that may cause a safety hazard.

Caution: Probes are sensitive devices——irreparable damage may occur if they are

dropped, knocked against other objects, cut, or punctured. Do not attempt to repair

or replace any part of a probe.

Caution: To avoid cable damage, do not roll the system over probe cables.

Caution: Do not use probe sheaths containing oil-based coatings or petroleum-or


102

mineral oil-based ultrasonic coupling agents. Use only water-based ultrasonic

coupling agent.

Caution: Take extreme care when handling or storing probes. They must not be

dropped, jarred, or knocked against other objects. Do not allow probes to come into

contact with any sharp-edged or pointed object.

5.2.3 Caring Coupling Agent

Caution: Before use, examine the coupling agent for any material flaws.. Thinning,

bulging, or brittleness of the material indicates damage. Any product showing flaws

should not be used.

Do not store coupling agent below 5°C nor above 57°C. Coupling agent have a limited

shelf life. Before use, examine these products for any material flaws. Some packaging

may list an expiration date. Any product showing flaws, or whose expiration date has

passed, should not be used.
