2. Care should be taken to avoid exposing the table to excessive moisture. Flooding, fogging or

steam cleaning is not recommended.

3. Blood or other fluids, etc., if allowed to remain on the table for a long period of time, will

require special cleaning to remove. A 5% acetic acid solution or white vinegar and water
solution is especially good for this purpose.

4. Cleaning with a good commercial cleaning compound, such as Stainless Steel Magic or

Acme White Finish, and then buffing the surface by hand can correct staining and
discoloration of plated or stainless steel surfaces only.

5. To disinfect exterior surfaces use a quaternary ammonium or similar type disinfectant

compound according to manufacturer's directions for use. Wipe dry with a soft lint-free
cloth.

NOTE: Failure to thoroughly dry surface after cleaning and disinfecting may result in rust.

Casters:
Casters should be cleaned and disinfected in the same manner as table exterior. Access to the
casters is achieved by removing the sheet metal enclosures at each end of the table base.

NOTE: Before removing any sheet metal covers the table must be turned off and unplugged.

Dangerous high voltage may be present in the circuitry under the covers. Only trained
technicians should perform this task.

10.0 GLOSSARY OF TERMS

Basic assumptions of patient orientation on the tabletop: our glossary of terms and technical
procedures assume the patient is normally oriented with their head at the “head end of table”
(toward Control Panel) and their feet at the “foot end of table” (toward Leg Spars). The Hand
Control functions are oriented for this position only.

“Head end of table” refers to the end of the table where the power cord, "ON/OFF" power
switch, and Control Panel are located; otherwise referred to as the “pedestal end”.

“Foot end of table” refers to the opposite end of the table also referred to the “leg spar end".

“Control Panel” is a panel of buttons and lights located on the head end of the table.

“Pedestal” refers to the main column structure that supports the tabletop.

“Left side of the table” refers to the table as you stand at the head end of table.
This also corresponds to the Hand Control button labeled “LEFT LATERAL ROLL”.

“Right side of the table refers to the table as you stand at the head end of table.
This also corresponds to the Hand Control button labeled “RIGHT LATERAL ROLL”.

“Raise the table” refers to raising the height of the table.
This also corresponds to the Hand Control button labeled “HEIGHT UP”.

“Lower the table” refers to lowering the height of the table.
This also corresponds to the Hand Control button labeled “HEIGHT DOWN”.

“Raise the foot end of the table” refers to raising the height of the foot end of the tabletop or leg
spars. The corresponding Hand Control button is labeled “TREN” (Trendelenburg).

“Raise the head end of the table” refers to raising the height of the head end of the tabletop.
The corresponding Hand Control button is labeled “REV TREN” (Reverse Trendelenburg).

“Level the table” refers to leveling the tabletop regardless of height. The corresponding Hand
Control button is labeled “RETURN TO LEVEL”. Holding the “RETURN TO LEVEL” button
longer than approximately three seconds will also lower the tabletop to its lowest position.

"Lock the floor locks" refers to lowering the floor locks. The floor locks, when locked down,
will prevent the table from rolling and enable all other table functions. The corresponding Hand
Control button is "FLOOR LOCK" and the "FLOOR LOCK ON" light will illuminate or Control
Panel button is labeled “DOWN TO LOCK” and the green "LOCKED WHEN LIT" light will
illuminate.

“Unlock the floor locks” refers to rising the floor locks up 1/2-inch off the floor, allowing the
table to freely roll on its wheels. The corresponding Hand Control button is "FLOOR UNLOCK"
and the "FLOOR LOCK STOWED" light will illuminate or Control Panel button is labeled “UP
TO UNLOCK” and the amber "STOWED WHEN LIT" light will illuminate.

“Hospital Grade" outlet refers to a 120VAC outlet properly wired with earth ground: Neutral to
Common = 120VAC; Neutral to Ground = 120VAC; Common to Ground less than zero point
five (0.5) VAC.
