ACCESSORIES DESIGNED BY OTHERS
Berchtold Corporation assumes no liability for
table performance when used with accessories
designed by others for use on Berchtold
equipment, or damage resulting to Berchtold
equipment resulting from the use of
accessories designed by others.
RADIOLUCENT TABLE TOP AND PADS
CAUTION
CAUTION — The anti-static
properties of the table depend on the
use of the recommended mattress.
Compromise of the anti-static
properties could expose the patient
or OR personnel to an electrostatic
shock. It could also deliver a shock
to the table’s electronics that could
damage or destroy critical
components.
CAUTION
CAUTION — Protect the top and
bottom surfaces from nicks and
scratches. Scratches more than
0.005 inches (127 microns) deep
may appear on x-rays. Damaged or
scratched panels should be replaced
if x-ray quality is affected.
FOOTSWITCH
CAUTION
CAUTION — The Footswitch’s
electrical connections are resistant
to fluid intrusion, but if fluid
drainage is anticipated, the
footswitch should be protected by
wrapping it with a clear disposable
footswitch bag. This will reduce the
need to disinfect the footswitch.
HYDRAULIC SYSTEM
WARNING
WARNING – POSSIBILITY OF
INJURY: The hydraulic system
must be kept free of contamination.
Contamination can cause the
hydraulic system to fail, resulting in
personal injury or equipment
damage.
CAUTION
CAUTION – The hydraulic system
on the OPERON D 850 surgical
table contains micro-hydraulic
valves, which are very sensitive to
contamination. Only a qualified,
trained service technician should
open the hydraulic system, and only
after all other repair procedures
have been tried. Always use clean
tools, and cover or wrap any loose
hydraulic lines with clean plastic
bags.
HYDRAULIC HOLLOW PLUGS
CAUTION
CAUTION – Do not over tighten the
hollow plugs. Over tightening can
cause the seals to deform and leak.
CAUTION
CAUTION — Hollow plugs used in
the hydraulic system have different
torque values than the mechanical
fasteners. See Table 4-1 for hollow
plug torque requirements.
HYDRAULIC FLUID
CAUTION
CAUTION – Do not mix hydraulic
fluid types. Other hydraulic fluids
can be incompatible with the seals in
the OPERON D 850 table and can
cause equipment failure or reduce
the service life. (See drawing
306762 for correct fluid
designation.)

OPERON D 850 SURGICAL TABLE
SPECIAL SAFETY INSTRUCTIONS
700000120 Rev. 1
S-11
ELECTROMAGNETIC INTERFERENCE
WARNING
WARNING — When using the table
in the vicinity of high-frequency
surgical equipment, such as cardiac
defibrillators and cardiac
defibrillator monitors, refer to the
equipment manufacturers’
instructions to ensure compatibility
issues are considered.
WARNING
WARNING — When using the table
in the vicinity of neuro-diagnostic
monitoring equipment, interference
may appear on the monitoring
device. To eliminate this, set the
BACKLIGHT TIMER to 1 sec using
the service software
ELECTRICAL SYSTEM
WARNING
WARNING – When servicing the
table, turn power off or remove the
appropriate fuses to prevent
personal injury. If power is
required, use care to avoid contact
with live parts.
WARNING
WARNING – Even a “dead”
battery can contain enough power to
cause a serious shock or explosive
spark. Always disconnect the
battery charger plug at the power
center before disconnecting cables.
WARNING
WARNING – The batteries contain
acid, which can cause serious burns.
While the batteries are sealed, a
dead battery may be damaged and
may leak. Always handle batteries
in a way that will prevent acid from
spilling on your skin or clothes.
CLEANING AND DISINFECTION
WARNING
WARNING — Unplug the power
cord before cleaning the table if
cleaning liquids will be used near the
power cord receptacle. Under no
circumstances should steam or
extremely hot water (over
150°F/66°C) be used to disinfect or
clean the table. Elevated
temperatures and high humidity will
weaken the hydraulic lines and result
in failure of the hydraulic system and
increased leakage currents. Do not
clean this table in automatic cart
washing equipment. Use of high-
pressure water guns could lead to an
electrical malfunction and must be
avoided.
CAUTION
CAUTION — Failure to thoroughly
dry the surface after cleaning may
result in rust.
WARNING
WARNING — Always replace fuses
with fuses of the same voltage and
current rating. Failure to use the
correct fuse could cause a fire and
injury to the patient or hospital
personnel.

GENERAL INFORMATION
GENERAL DESCRIPTION
The Berchtold OPERON D 850 surgical table
is a remote controlled, full-function design
offering a high level of patient positioning and
imaging flexibility to the surgical team. The
table can be activated by AC power through
the power cord (input range of 115V ±10%) or
by battery power, which requires no power
cord except when charging the batteries.
An electric motor with a belt driven screw is
used to slide the table top head to foot.
Hydraulic cylinders are used to articulate the
table's sections. Hydraulic pressure is
provided by a motor driven pump during
normal use, and by a manual foot pump in
manual back-up mode.
A hand-held control pendant is used to control
table positions.
The tabletop is divided into the following
sections:
•Headrest
•Back Section
•Kidney Elevator
•Seat Section
•Leg Section
A leg extension can be added to extend the
tabletop surface.

RADIOLUCENT TABLE TOP AND PADS
CAUTION
CAUTION — The anti-static
properties of the table depend on the
use of the recommended mattress.
Compromise of the anti-static
properties could expose the patient or
OR personnel to an electrostatic shock.
It could also deliver a shock to the
table’s electronics that could damage
or destroy critical components.
The tabletop surface is made from electrically
conductive radiolucent panels. The table is
fitted with a matching set of conductive
radiolucent pads. Velcro tape holds the pads
in place.
CAUTION
CAUTION — Protect the top and
bottom surfaces from nicks and
scratches. Scratches more than 0.005
inches (127 microns) deep may appear
on x-rays. Damaged or scratched
panels should be replaced if x-ray
quality is affected.
Each table section has a cassette channel that can
accommodate x-ray cassettes up to 14'' x 17'' (356
x 432 mm).
INTERCHANGEABLE HEADREST
The headrest can be attached to the seat section to
allow for positioning the patient toward the leg
end of the table.
POWER SUPPLY
WARNING
WARNING — Repeated breaker
tripping or fuse replacement may
indicate a ground fault or overload
condition. The table will not operate
reliably under these conditions, and
may be electrically unsafe. Do not use
the table until these conditions are
corrected.
NOTE
NOTE — Recharge the batteries as
indicated by the battery indicator on
the control pendant. For longevity, it is
good practice to charge the batteries at
least once a week

components are shown in Figure 1-2.
When the table is plugged into a 120VAC
receptacle, it is powered by AC (mains). When
the power cord is not plugged in, the batteries
provide power to the table. In either case, the
ON/OFF switch on the base must be ON to
articulate any table sections. When the ON/OFF
switch on the base is OFF, the table's electronics
and pump motor are isolated from the power
supply and the batteries, regardless of the pendant
used.
When the charge indicator lamp near the power
cord receptacle is lit, the table senses AC power
and activates the battery charging system. If AC
is present, the battery charging system is activated
whether the ON/OFF switch on the base is in the
ON or OFF position. The table can remain
plugged into AC indefinitely without damaging
the batteries. The battery indicator on the primary
hand pendant displays the battery charge status.
This display has three sections: green (full
charge), yellow (low charge), and red (recharge).
Only one color will be activated at a time.
NOTE
NOTE — In the unlikely event of a
control pendant failure, the table
movements can be stopped by switching
the breaker on the base to the off
(down) position.

FLOOR LOCK SYSTEM
Four self-stabilizing floor feet compensate up to
0.25'' (6 mm) for uneven floors. The floor feet can
be lowered (locked) or raised (unlocked) using the
control pendant. When the floor feet are raised,
the table rests on four non-conductive casters.
FUSES
Fuses are accessible without removing the base
covers.
They are located within the receptacle for the
power cord, contains two fuses. These fuses
protect against current surges in the AC (mains)
line.
In addition to the fuses, the ON/OFF switch serves
as a circuit breaker with a 20 Amp rating.
See Figure 1-2 for the fuse locations.
PRIMARY HAND PENDANT
A primary hand pendant controls all table
functions. The floor feet must be locked by
activating the FLOOR LOCK function to operate
any other pendant functions. This ensures that the
table base will not move while the tabletop is
articulating.
The primary hand pendant plugs into the
PATIENT LEFT side of the remote control
connector box, which is located on the head end of
the column beneath the table top. Insert the
pendant so the red dot on the connector aligns with
a red dot on the socket in the Primary Hand
Pendant Connector Box.
NOTE
NOTE — The ON/OFF function on the
control pendant can be used to stop the
table while in motion.
AUXILIARY HAND PENDANT
The Auxiliary Hand Pendant is identical to
Primary Hand Pendant and can be used as a
replacement for a failed Primary Hand Pendant.
To replace the Primary Hand Pendant, unplug it
from the Primary Pendant receptacle and plug in
the Auxiliary Pendant. The Auxiliary Hand
Pendant will now have all of the functions and
indicators of the Primary Hand pendant.

PRIMARY HAND PENDANT INDICATORS
See Figure 1-3 for the location of the indicators
1. AUX. PENDANT (amber flashing) —
Auxiliary hand pendant is active. The primary
hand pendant will be disabled if the auxiliary
hand pendant is active.
2. SERVICE (red) — Table malfunction. It is
likely that most of the functions still work
properly and can still be controlled from the
primary hand pendant. If the control pendant
is not working, use the auxiliary hand pendant
and the manual foot pump (if necessary) to
articulate the table until the malfunction can
be repaired.
NOTE
NOTE — If the SERVICE indicator lights,
call your local Berchtold Corporation
Service Representative.
3. TABLE LIMIT (amber flashing) —
Indicates that the movement commanded has
reached a software controlled limit to avoid
damage to the table components.
4. POWER (green) – hand pendant is active.
Backlight may or may not be lit.
5. FLOOR UNLOCK ²(amber) — Floor feet
are raised so table is mobile.
6. FLOOR LOCK ±(amber) — Floor feet are
lowered so table is locked in place.
7. SPEED ADJUST HI (green) – articulation
speed of all functions is set to normal.
8. SPEED ADJUST LO (green) – articulation
speed of all functions is set to low.
9. BATTERY — LEDs indicate the charge
status of the batteries:
•Green — Full to medium charge. Normal
Operation.
•Yellow — Low charge. Table still
operates normally, but batteries should be
charged at the first opportunity.
•Red (steady) — Recharge battery. Pump
motor is shut off and manual foot pump
must be used.
•Red (flashing) — Auxiliary pendant must
be used. Recharge battery immediately!
NOTE
NOTE — In the event of a primary hand
pendant failure, use the auxiliary hand
pendant and foot pump to complete the
procedure and contact your local
Berchtold Corporation Service
Representative.
10. BACKLIGHT – Pendant backlighting
(electroluminescent panel) combined with
the green Power LED indicates that the
pendant is active. The Backlight will time
out after a preset time period, which can be
set in the service software. The backlight
timer can be set to a shorter time than the
Controls Wakened state. This will reduce
electrical current drain on the batteries,
slightly extending the battery charge cycle.
The lowest backlight timer setting is 1
second.

Pressing one of the footswitch controls turns the
table on and places it in “controls active” status.
However, none of the functions will operate
unless the floor locks are set. The floor locks
must be operated through the hand pedant.
MANUAL FOOT PUMP
The manual foot pump is used to provide
hydraulic pressure when there is no electric
power to operate the hydraulic pump. This
could occur due to any of the following
conditions:
•Battery power is low as indicated by a
steady or flashing red battery light on the
hand pendant.
•A combined failure of the battery and AC
mains power supplies.
•A failure of the table’s hydraulic pump or
the electrical system that powers the
hydraulic pump.
•A failure of table controls
The manual pump pedal is located at the patient
left side near the head end of the base.
DEPLOYING THE FOOT PUMP HANDLE
TO ITS FULL OUTERMOST POSITION
ENABLES THE AUXILIARY PENDANT
AND DISABLES THE MAIN HAND
PENDANT.
To use the manual foot pump:
1. Pull the foot pedal straight out as far as it
will go. It will rotate counter clockwise
as it is pulled outward.

1. Push the pedal back into the table until
the end is inserted into the base cover.
2. Continue to push the pedal into the table
until it snaps into the retracted position.
EMERGENCY UNLOCK
In the unlikely situation where the control
system is completely disabled AND the
auxiliary system is disabled, there is a back-up
emergency switch that will allow the table to be
unlocked and moved. It is wired directly to the
batteries. There should always be enough power
in the batteries to open the valve solenoids. This
switch is located inside the base near the foot
pump handle storage location.
