J/V-Generation™ ChairSection II Features
DentalEZ combined the thin, narrow back and
independent seat tilt of the J-Chair
split-back of the V-Chair
, along with an anatomi-
®
with the flexile
cally correct hip pivot point and left/right flexibility,
then added a new, sleek, modern look to develop the
J/V-Generation Chair.
The DentalEZ J/V-Generation Chair can be customized to attain optimum work efficiency so dental
professionals can offer quality care and treatment to
patients.
In order to achieve the most efficient use in the
operatory and understand what the J/V-Generation
Chair offers, here is a compilation of some standard
and optional features:
Standard
Ergonomic/Comfort Features
The J/V-Generation Chair allows total patient placement flexibility to create the most comfortable
working position for the patient and dental team.
Some of these ergonomic and comfort features are:
u Exclusive, independent seat tilt feature allows
precise positioning of the patient to reduce
operator eye, back and neck strain, while still
placing the patient in the most comfortable
position.
u Thin, narrow back provides the best operator
access to the oral cavity without any need for
reaching or twisting.
Design Features
u Both arm rests rotate up allowing for easy
patient entry/exit from right or left eliminating
the need for any tools to change the operatory
from right to left, and provides easy access for
handicapped patients.
u Availability of eight pre-set positions plus
manual controls for back/base height and seat
tilt increases efficiency by reducing time needed
for chair adjustment.
u Adjustable controls can be located on both the
dentist's and assistant's side of the chair to
provide easy and rapid patient positioning.
u Arm slings hold the patient's arms closer to their
bodies allowing the dentist better access to the
oral cavity.
u A variety of headrests, that can be easily and
quickly changed, is available to accommodate all
dental procedures.
Safety Features
u A base lowering safety features ensures nothing
gets caught underneath the base as it lowers. (See
Operation Section.)
u A locking chair brake holds the chair in place and
stops any swivel movement. (See Operation Section.)
u The handpiece operated chair movement lock-
out prevents any unexpected chair movement
while operating any handpiece.
u Contoured, no-obstruction design eliminates all
obstacles from the operator's thighs and knees
allowing for a more ergonomically correct
position.
u Anatomically correct hip pivot point increases
patient comfort during long procedures.
4 Installation, Operation and Care Manual
Optional
u Air glide feature allows free and easy floor
positioning of the chair.
u An AC light receptacle outlet can be added to
the chair's AC power.
u Lights can be operated using the auxiliary light
relay button on the touch pad control.

Special Installation Mode
J/V-Generation™ Chair
FRONT VIEW
Phillips-head Screws
The J/V-Generation Chair is shipped in a special
installation mode. In this mode, just the chair base
rises to its upper limit without the use of a controller.
When the chair power is connected, the chair base
will automatically rise until it contacts the base upper
limit switch and stop. Then, the chair base will lower
itself slightly to its final resting position.
While the chair is in this special installation mode, it
will emit a constant fast beep. Even after the base has
stopped its motion, this beep will continue as a
reminder that the chair is in its special mode.
Raising the chair base will give better access to the
base cover rear screws making removal of the base
cover easier. It will also provide extra work space to
service the chair or install any chair-mounted units.
To take advantage of this special installation mode,
perform the following six steps:
1. After all shipping hardware is removed and the
chair is in its permanent location, connect the
chair power cord to the required power source.
2. The chair base will automatically rise as
described above.

Activating Auto Positions
To activate the auto positions:
1. Determine A or B user by depressing the A/B
toggle button. The A (green) or B (yellow) LED
will light and one beep will sound for A mode
and two beeps will sound for B mode.
2. Depress the #1, 2, 3 or 4 button once on the

touch pad control.
3. A beep will sound.
4. The chair will automatically stop in the
programmed position selected.
NOTE: Pressing any button on a chair control module
while the J/V-Generation Chair is moving to a programmed position will immediately stop the movement
of the chair, and three short beeps will sound. To continue
and complete the automatic positioning of the chair,
simply press the desired position button a second time.
Reprogramming Auto Positions
To change a programmed position, simply maneuver
the J/V-Generation Chair to the desired position and
follow the Programming Auto Positions instructions
described earlier in this Section.
NOTE: Reprogramming a new auto position spontane-
ously erases the old position.
Controller Functions/Modes
Command Time-out
When a function is moved or an auto position is
activated, the chair assumes movement completion
will take no longer than 45 seconds.
If a function button has been held down or an auto
position has not completed in this allotted time, the
chair will reset itself and restart as though it were
being powered up.
If a button is stuck on a controller, it will fail the
calibration test when the chair restarts and the original
command will be ignored.
If an auto position was activated and for some reason
could not be completed, the chair will not continue trying completion of this command when the chair restarts.
Silent Mode
Anytime a function position button is pressed, a short
beep sounds letting the operator know a function
move has started. These short beeps can be silenced
by changing the #3 DIP switch to the OFF position.
(See Section VII, Dip Switch Settings for details.)
Potentiometer Override Mode
In the event one of the three potentiometers used to
measure each function's position on the chair cannot
be read, the chair will automatically switch to a manualonly mode. In this mode, the chair can only be
manually positioned, and the affected function's travel
limits will be its limit switch position or physical limit.
Controller Self-Calibration
When power is first connected to the chair, each
attached controller having its associated DIP switch
set to the ON position is tested and calibrated.
If a controller does not pass the calibration test, its
commands are ignored and an associated LED code
is generated letting the user know the controller failed
the calibration test.
While the chair is idle, approximately every 15 minutes, the attached controllers are tested and calibrated
to ensure they are working as expected.
A constant fast beep will sound while an affected
function is being moved to alert the operator the
function requires service. When the affected function
is idle, no beep signal will sound.
All other functions that are operating normally will maintain their programmed travel limits without audible signals.
Auto positions cannot be set or activated in this mode
because at least one of the function's positions
cannot be measured.
If any auto position buttons are pressed, the chair will
sound three short beeps to indicate auto positioning
is not available and the chair is in manual-only mode.

J/V-Generation™ ChairSection V Operation
Standard Features
Base Lowering Safety
The following describes how this feature operates:
1. When the base cantilever section lowers and
contacts an obstruction, the cover on the
underside of the cantilever section moves up
and activates safety switches.
2. Motion of the base stops immediately and the
chair emits a constant short warning beep.
NOTE: As long as the safety switches are activated,
the base will not lower any further. All other chair
functions, except auto programs, are still available. If
the chair is moving to an auto position and the base
cover moves up activating the safety switches, auto
positioning will stop.
3. Moving the base up and off the obstruction
deactivates the safety switches and silences the
warning beep.

Beep Codes
The J/V-Generation Chair's electronic control package is designed to sound specific beep code signals to
alert the operator of certain control conditions.
Understanding the beep codes enables the operator to
isolate the condition and take appropriate action.
Base conditions are indicated by a constant short
beep; back conditions by two constant short beeps;
22 Installation, Operation and Care Manual
and seat conditions by three constant short beeps.
Three short beeps indicate a function is not available
when its button is pressed. A constant fast beep that
sounds only when a function is moved indicates a
potentiometer condition.
The beep code signal chart on the following page lists
the audible sound, control condition and service
action to take. The codes are also prioritized letting
the user know that conditions listed above the indicated code are normal.

Control Valve Speed Adjustment
Tools Required:
Phillips Screwdriver
Flat-head Screwdriver
Safety Glasses
1. Raise the chair base to its full UP position.
2. Take off the base (pump) cover by removing
and retaining the four Phillips-head screws
that attach it to the base plate.
NOTE: Adjustable flow control valves, located in the
hydraulic control valve, are used to set the chair function
speeds. The base and back cylinders are single acting
cylinders. They have two flow control valves each (UP
and DOWN) to control their speeds. The seat cylinder
is double acting and requires four flow adjustment
valves. Valves marked (PWR) are for incoming
fluid. Valves marked (RET) are for outgoing
fluid. The (RET) valves are adjusted first to set a
gross speed and the (PWR) valves are used for fine
tuning the speeds. Once the (RET) flows have been set,
they should not be readjusted.
Function times given are based on a 200-pound person
sitting in the chair.
— WARNING —
Wear safety glasses while adjusting the valve.
Flow control valves should not be turned out
farther than the top of their heads being even
with the valve body surface. Adjustment of
the flow control valves beyond the valve body
surface may result in oil leakage with uncontrolled motion of the chair and the possibility
of a valve being ejected from the valve body.
a. Move the base up and down adjusting the
flow controls until it takes 12 seconds for
the base to move either up or down the
full travel.
b. Move the back up and down adjusting the
flow controls until it takes 12 seconds for
the back to move either up or down the
full travel.

flow adjustments all the way closed
(clockwise).
NOTE: With the flow adjustments closed all the way,
the seat may not move at all until the valve is adjusted
open a little.
e. Move the seat up or down while opening
the corresponding (RET) flow
adjustments.
f. Continue adjusting the flows until the seat
moves from its full up and down positions
in about seven seconds both ways.
g. Adjust the UP (PWR) and DOWN (PWR)
flow adjustment screws all the way closed
(clockwise).
h. Move the seat up or down while opening
the corresponding (PWR) flow
adjustments.
i. Continue adjusting the flows until the seat
moves from its full up and down positions
in about nine seconds both ways.
3. Raise the chair base up.
