e. Operational Check. The operational tests in this section are also needed to
ensure patient safety and ease of operation. When performing these tests, pay
particular attention to smoothness and ease of operation. Make sure there is no
difficulty of operation, squeaking or other unusual noises, or malfunction(s). Exercise all
table motions as follow. (See figure 1-2 for switch locations.)
Figure 1-2. Table side controls.
(1) Press and hold the longitudinal foot switch (B) until the table top reaches
its limit of travel. It should move approximately 30 inches from its centered position,
before it stops.
(2) Press and hold the longitudinal head switch (A) until the table top
reaches its limit of travel. It should move approximately 30 inches from its centered
position, before it stops.
(3) Press and hold the table center switch (C) until the table top stops. It
should move to its center position, from either of the above mentioned longitudinal
positions, before stopping.
(4) Press and hold the Trendelenburg tilt switch (D) until the table reaches
its maximum tilt. It should tilt 12 degrees toward the head end (-12 degrees
Trendelenburg) and stop.
(5) Press and hold the vertical tilt switch (E) until the table top reaches its
maximum tilt. The table should tilt 88 degrees toward the foot end before it stops.
(6) Engage all locks and attempt to reposition the spot-film device in all
directions; it should take a minimum of 20 pounds of force to move a corresponding
part. The locks should not make a "banging" sound when engaged.
