3.0 BASIC OPERATION
The 5892 Base can be operated only on AC power. Plug the AC Power Cord into the proper AC
receptacle depending on the voltage requirements of the 5892 Base. Refer to the label at the
Head End Base for input voltage requirements. Turn the ON/OFF Power Switch to “ON”. It will
illuminate green indicating power is ON. The ON/OFF Power Switch is a combination power
switch and circuit breaker. To reset this circuit breaker, turn the ON/OFF Power Switch “OFF”
and back “ON”.
3.1 Control Operation
The 5892 Base is controlled by means of a Hand Control that operates the Up/Down, Lateral Tilt
and Trendelenburg / Reverse-Trendelenburg movements of the table. See Hand Control Section.
The Head-end Pivot Assembly of the 5892 Base is equipped with three indicator lights (shown
below):
1. 180° Rotation Lock Indicator Light
2. Tilt Drive Status Light
3. Rotation Safety Lock Indicator Light
Verify that the Rotation Safety Lock switch is “ON” and the 180°Rotation Lock Lever is in the
locked position. Under normal operation, the ON/OFF Power Switch should be illuminated
green and Battery Status Light should not be illuminated.
Figure 5: Head-end Pivot Assembly, Indicator Lights and Controls
3.2 Rotation Safety Lock
The Rotation Safety Lock Lighted Switch locks out the 180°Rotation function. This feature is
designed to prevent unintended rotation of the Table Top. When the Rotation Safety Lock
Lighted Switch is illuminated, the Table Top can still be Laterally Tilted by pressing the Left or
Right Lateral Tilt button on the Hand Control. The Rotation Safety Lock Switch should be
turned off only when a 180 rotation is to be performed. If the Rotation Safety Lock Switch is not
illuminated, press the rocker switch to the “ON” position.

3.3 180-Degree Rotation Lock Indicator
When lit, the 180° Rotation Lock Indicator Light indicates the 180°Rotation Lock is engaged
and the table cannot be rotated 180°. If the 180°Rotation Lock Indicator is not lit, rotate the
Rotation Lock Lever clockwise until the light is illuminated.
NOTE: If a 180° rotation is to be performed, the Rotation Lock Lever should be rotated
counterclockwise approximately one half rotation past the point that the Rotation Lock Indicator
Light goes out. Rotating the Lock Lever to this point lessens the drag of the friction control,
thereby allowing the Table Tops to rotate more freely during the rotation. If even less friction is
desired, the Lock Lever may be rotated further, counterclockwise, as necessary.
After the rotation is complete, rotate the Rotation Lock Lever clockwise until the Rotation Lock
Indicator Light is illuminated.
NOTE: When the Rotation Lock Indicator Light is not illuminated, the Table Top is unlocked
regardless of how much the Lock Lever has been rotated clockwise or counterclockwise. After a
180° Rotation, always rotate the Lock Lever until the Rotation Lock Indicator Light is
illuminated.
3.4 Tilt Drive Status Indicator
The Tilt Drive Status Indicator Light is lit when the power lateral tilt mechanism is in the center
position of the +/-25-degree powered lateral tilt range. If the Tilt Drive Indicator is not
illuminated, operate the lateral tilt function using the Hand Control in the appropriate direction
until the indicator is lit. The Head End Crossbar should be horizontal when the Tilt Drive Status
Indicator is lit. If the Head End Crossbar is not horizontal, the internal power tilt mechanism is
out of synchronization with the Crossbar. Refer to Synchronizing the Lateral Tilt Function to
reset this function.

NW0352
Rev. B

3.5 Hand Control Module
Each 5892 Base is equipped with a hand-held Pendant Control (Hand Control), which is on a
storage bracket attached to the Head-end. The Hand Control allows the operator to raise, lower,
Trendelenburg, reverse-Trendelenburg, and laterally tilt the table. The selected function will
continue to operate until the button on the Hand Control is released.
NOTE: It is recommended that a Table Top always be connected between the Head and Foot
Ends when operating the powered controls.
To Raise theTable, depress the Table Up
Button (a) on the left side of the Hand
Control with the arrow that points in the
“up” direction.
To Lower the Table, depress the Table
Down Button (b) on the right side of the
Hand Control with the arrow that points
in the “down” direction.
To Trendelenburg the Table, depress
the button on the left with the arrow that
indicates Foot Up (c) until the desired
Trendelenburg angle is achieved. This
lowers the Head-end Column and raises
the Foot-end Column simultaneously. If
the Table is in a fully lowered position,
only the Foot-end will rise to achieve the
desired Trendelenburg angle.
To Reverse Trendelenburg the Table,
depress the button on the right with the
arrow that indicates Foot Down (d) until
the desired Reverse Trendelenburg angle
is achieved. This raises the Head-end
Column and lowers the Foot-end
Column simultaneously. If the Table is
in afully raised position, only the Foot-
end will lower to achieve the proper
Reverse Trendelenburg angle.
To Laterally Tilt To The Left
, depress
the Left Tilt button (e) on the left side of
the Hand Control.
To Laterally Tilt To The Right,
depress the Right Tilt button (f) on the
right side of the Hand Control.
NOTE: In the event a Traction Arc is placed on the Base, the Tilt function has been made
inoperable.

3.6 Synchronizing The Lateral Tilt Function
The Power Tilt Drive and the Head-end Crossbar are synchronized so that the drive is in the
middle of its travel range when the Crossbar is level. However, the Drive and Crossbar can
become unsynchronized during manual rotation of the Crossbar. If this occurs, they need to be
re-synchronized. Furthermore, the Head-end Crossbar and Foot-end Crossbar can be
unsynchronized (not at the same tilt angle) if the 5892 Base was operated without a Table Top in
place. The Crossbars must be synchronized to each other, as well as to the Tilt Drive.
NOTE: Never attempt to attach a Table Top to the 5892 Base if the Head and Foot-end
Crossbars are not horizontal in all planes. Tilt Drive Status, Rotation Safety and 180° Rotation
Lock Lights should be illuminated. Doing so may cause damage to the Table Top or the Tilt
Drive function.
To verify synchronize of the Tilt Drive and Head-end Crossbar:
1. Confirm that the 180°Rotation Lock is engaged.
2. Confirm that the Rotation Safety Lock is engaged.
3. Use the Hand Control tilt buttons to rotate the Head-end Crossbar until it is level.
4. Observe the Tilt Drive Status Indicator Light. If it is ON, then the Head-end Crossbar is
synchronized to the tilt drive. If it is OFF, then they are not synchronized.
5. If you could not level the Head-end Crossbar using the tilt buttons, then the drive and
crossbar are not synchronized.
To re-synchronize the Tilt Drive and Head-end Crossbar:
Case 1: Table Top is coupled to the 5892 Base.
1. Confirm Table Top is clear (i.e., no tools)
2. Turn ON/OF Power Switch to “ON”.
3. Turn OFF the Rotation Safety Lock. The switch should go dark.
Rotate 180°Rotation Lock Handle counter-clockwise until Rotation Lock Indicator Light
goes out.
Caution – this allows the Table Top to swing freely.
4. The Drive Mechanism will automatically return to the middle of its range. While this occurs,
you will hear the Tilt Motor running, but the Table Top will only rotate a little (if at all).
5. When the Tilt Motor stops, observe the Tilt Drive Status light. If it is ON, then the drive is in
the middle of its travel range.
6. Verify that the Head and Foot-end Crossbars are level.
7. Turn ON the Rotation Safety Lock. The Indicator Light should illuminate.
8. Rotate the 180°Rotation Lock Handle clockwise until it is engaged (Lock Indicator Light is
illuminated).
9. The Tilt Drive is now synchronized to the Crossbars, and the Crossbars are synchronized to
each other.
Case 2: A Table Top is not coupled to the 5892 Base.
1. Turn ON/OF Power Switch to “ON”.
2. Turn OFF the Rotation Safety Lock. The switch should go dark.
Caution – this allows the Foot-end crossbar to rotate freely; any load on the Crossbar can
make it swing.
3. Rotate the 180°Rotation Lock Lever counter-clockwise until it is disengaged.
Caution – this allows the Head-end Crossbar to rotate freely; any load on the Crossbar can
make it swing.

NW0352
Rev. B

4. The Drive Mechanism will automatically return to the middle of its range. While this occurs,
you will hear the Tilt Motor running, and the Head-end Crossbar may rotate.
5. When the Tilt Motor stops, observe the Tilt Drive Status light. If it is ON, then the Drive is in
the middle of its travel range.
6. Manually level the Head-end Crossbar.
7. Manually level the Foot-end Crossbar.
8. Turn ON the Rotation Safety Lock Switch. The Switch should illuminate.
9. Rotate 180°Rotation Lock Lever, clockwise, until it is engaged (Lock Indicator Light is lit).
10. The Tilt Drive is now synchronized to the Crossbars and the Crossbars are synchronized to
each other.
3.7 Tabletop Coupling Procedure
The Modular Table Tops may be interchanged and coupled to the 5892 Base as needed to
provide flexibility and specific procedural capability. Position the 5892 Base and engage all four
Caster Locks. Only Table Tops with Gimbals may be used with the 5892 Base.
Figure 7: Jackson Spinal Top & Imaging Top with Gimbal Mounting Assemblies.
NOTE: Verify that the Jackson Spinal Top or the Imaging Top being used has Gimbals. Never
attach a Jackson Spinal Top or Imaging Top to the 5892 Base that does not have Gimbals.
The following procedure assumes the Foot End and Head End Columns do not have Table Tops
coupled in place. The coupling procedure is as follows:

Figure 9: T-Pin Assembly
1. Remove the H-Frame from the H-Frame Storage Bracket located on the Head-end Column.
Install the H-Frame to Head-end Crossbar and secure with a T-Pin. The T-Pins are stored in
the T-Pin Quiver located adjacent to each column. The T-Pin must extend completely
through both sides of the H-Frame and the Drop Lock should be in sight and pivot freely.
The Head-end Crossbar is attached to a Sliding Assembly that adjusts superiorly and
inferiorly to accommodate Trendelenburg and Reverse Trendelenburg. Fully retract the
Head-end H-Frame against the Head-end Column.
NOTE: If the H-Frame is not aligned with the mounting studs, it may bind. Do not force it. Lift
the H-Frame off and repeat until it mounts easily.
Figure 10: Head-end Pivot Assembly, H-Frame Installed
NOTE: Two people are required to complete the following sequence.
2. Select the appropriate mounting-hole position on the H-Frame to support the tabletop. Hole
selection will differ depending on the top selected and the procedure that would be
performed. Align the mounting tube with the hole in the H-frame and push the T-pin
completely through the H-frame and mounting tube on the foot end.
NOTE: Verify that the T-pin is inserted through the H-frame, passes completely through the
table mounting tube, and through the opposite side of the H-frame and the T-pin drop lock is in
sight and pivots freely. Failure may result in the tabletop being dropped.

3. To couple the Head End of the Table Top, slide the H-Frame and Crossbar away from the
Foot-end as necessary to accommodate the length of the Table Top. Align the holes in the
Head-end H-Frame and the Table Coupling Device. Push the T-Pin completely through both
sides of the H-Frame and the Coupling Device making certain that the Drop Lock is in sight
and pivots freely. The Head-end and the Foot-end of the Table Top are normally coupled at
the same hole in the H-Frame. The only exception is when extreme Trendelenburg is needed.
NOTE: Prior to Rotation, verify that all Table Coupling Devices and H-Frames are properly
installed and the T-Pins pass completely through the H-Frames and Crossbars with the Drop
Lock in sight and pivots freely. Two (2) T-pins and Drop Locks should be visible and checked at
each end of the Table. Please read more about this process in the appropriate top-specific User
Guide.
3.8 Tabletop Coupling Procedure With Top In Place
When one Table Top is already coupled to the 5892 Base and you are coupling a second Top in
order to change Tops or facilitate a 180-degree tabletop rotation, the slide mechanism of the
Head End Sliding Assembly will be held in a fixed position due to the fixed length of the first
Top. This requires a different procedure to couple the second Top.
With two people holding the second Top:
1. Attach the Head-end H-frame as described above to the Table Top at the desired Mounting
Hole.
2. Position the second Table Top and attach the Head-end H-Frame to the Head-end Crossbar.
3. Attach the Foot End H-Frame to the Foot-end Crossbar surrounding the Table Top Coupling
Device.
4. Connect the Table Top Coupling Device to the Foot-end H-Frame at the desired mounting
hole. Verify that the Table Top is coupled at the desired height at the Head End.
3.9 Rotation Procedures
The 5892 Base provides the capability of rotating a tabletop 180 degrees. This is a manually
activated function.
NOTE: At least two people are required to hold and control the rotating motion of the Table
Tops. Prior to rotation, verify that all tabletop coupling devices and H-frames are properly
installed; the T-pins pass completely through the H-frames and crossbars with the drop locks in
sight and able to pivot freely. Four (4) T-pins and drop locks should be visible and checked at
each end of the Table.
3.10 Rotation Lock System
See Figure 11
The 5892 Base is designed to engage the Rotation Safety Lock automatically whenever the
ON/OFF Power Switch is turned “OFF”. Automatic Rotation Safety Lock engagement ensures
that the Table Top cannot rotate laterally without power.

NW0352
Rev. B
16
3.11 Rotation Procedure
With an attendant at the Head-end of the Table:
1. Release the 180°Rotation Lock by rotating the lever counterclockwise until the 180°
Rotation Lock Indicator Light goes out.
2. Advise the attendants holding the tabletops that the Rotation Safety Lock is about to be
released.
3. Release the Rotation Safety Lock by pressing the rocker switch to the OFF position.
Observe that the Indicator Light goes out.
4. Rotate the tabletops.
NOTE: The attendant performing the Rotation must rotate the tabletops 180°toward himself or
herself without stopping until the complete 180° rotation is achieved.
After the Rotation:
1. Immediately engage the Rotation Safety Lock by pressing the rocker switch to the ON
position and observe that the Indicator Light is illuminated.
2. Lock the 180°Rotation Lock by rotating the Lever clockwise until the 180°Rotation Lock
Indicator Light is illuminated.
NOTE:The attendant performing the Rotation may now release the Table Tops.
3.12 Emergency Rotation Lock Override System
The 5892 Advanced Control Base is designed to engage the Rotation Safety Lock automatically
whenever power is lost, (either by turning OFF the main Power Switch or in the event of a power
interruption). Automatic Rotation Safety Lock engagement ensures that the Table Top cannot
unintentionally rotate laterally without power.
If power is lost during a 180° rotation, the Rotation Safety Lock will engage and prevent the
table from rotating. The 5892 table base has an Emergency Rotation Lock Override Button
(ERLOB), located under the head-end and to the right side of the base (see figure 11). To
override the lock, depress and hold the ERLOB button, this will release the Rotation Safety
Lock; release of the ERLOB butoon will engage the Rotation Safety Lock. During the override
mode the indicator lights will illuminate for thirty seconds, then turn off, and the battery fault
lamp will also illuminate indicating a loss of AC power.
