Section V Operation
Activating Auto Positions
Command Time-out
To activate the auto positions:
When a function is moved or an auto position is
activated, the chair assumes movement completion
will take no longer than 45 seconds.
1. Depress the #1, 2, 3 or 4 button once on
either the touch pad control or the foot
control.
2. A beep will sound.
3. The chair will automatically stop in the
programmed position selected.
NOTE: Pressing any button on a chair control module
while the aXcs 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 aXcs Chair to the desired position and follow the
Programming Auto Positions instructions described
earlier in this Section.
NOTE: Reprogramming a new auto position spontaneously erases the old position.
Controller Functions/Modes
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.
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 two 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.
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.

Disinfecting
Upholstery
The aXcs Chair's upholstery is comprised of a sulfide
stain, oil and mildew resistant material which provides
outstanding protection in difficult medical and health
care environments. This material contains antibacterial/antimicrobial agents that are effective against
some of the following microorganisms:
Bacterial Species:
w Bacillus Subtilis/Cersus/Mycoides
w Staphylococcus Aureus
w Oseydinibas Aeruginosa
w Aerobacter Aerogenes
w Proteus Vulgaris
w Brevibacterium Species
w Streptomyces Rubrireticuli
w Escherichia Coli
w Klebsiella Pneumoniae
w Pseudomonas Aeruginosa
Fungal Species:
w Aspergillus Niger
w Aspergillus Flavus
w Penicillium Funiculosum
w Penicillium Islandicum
w Chaetonium Globosum
w Trichoderma Species
w Auerobacidium Pullulene
w Candida Albicans
High-Level Disinfection
The aXcs Chair's upholstery material is formulated to
withstand high-level disinfection, which is required in
medical/dental applications. Disinfectant products
that contain sodium hypochlorite (household bleach)
can be used full strength or with gluteraldehydes.
Intermediate-Level Disinfection
This level of disinfection is achieved by applying
either rubbing alcohol or a solution comprised of one
part household bleach (sodium hypochlorite) and nine
parts water. Because sodium hypochlorite is easier to
apply, its use is preferred over rubbing alcohol. To
achieve intermediate-level disinfection, rubbing
alcohol must remain puddled on the upholstery's
surface until evaporation is complete.
All Other Chair Surfaces
*Cavicide™ is recommended for disinfecting all other
surfaces of the aXcs Chair. The use of any disinfectant,
other than Cavicide™, may cause premature staining,
discoloration or damage to the aXcs Chair's materials.
*Cavicide™ is a trademark of Micro Aseptic Products, Inc.

DIP Switch Settings
A DIP switch assembly, which is located at the top
center of the main control board under the base
cover, is used to set certain functions of the chair's
electronic control package.
#1 DIP
Switch
— IMPORTANT —
Change DIP switches only while the chair
power is disconnected. Once the chair power is
reconnected, the main control board will
recognize any changes made.

NOTE: The main control board expects at least one
controller attached to the M (main) wiring connector. If
there is no controller attached to either the M or A (auxiliary) connectors, the board will generate a service LED code
that indicates one of the controllers needs checking.
