3.9.3. Adjustment-No.26 Headrest
3.9.3.1. There are three adjustments provided on the No.
26 headrest. The rst is the tension on the pad rotation.
By tightening the two hex acorn nuts on the pad pivots with
a 3/8” open end wrench, the tension will be increased. To
adjust the drag on the pivots of the articulating arm, loosen
the set screw in the center of the pivot with (Figure 4, item
1) a 3/32” hexagon key wrench. Next, tighten the pivot
screw on the other side of the pivot, with a 1/8” hexagon
key wrench. Now, retighten the set screw to retain the
pivot screw at the new adjustment. Either pivot may be
adjusted.
FIGURE 4
3.9.3.2. The third adjustment is for proper clearance of the
block dot to indicate that the headrest is properly locked.
If the dot does not fully clear the lock housing when the
headrest is lock securely, turn the set screw located at the
top of the lock housing (Figure 4, item 2) counterclockwise
until the dot on the actuator is fully exposed.

the chair.
3.7.2. The movements of both arms are identical and
completely independent of each other.
3.7.3. To raise an arm, push rearward on the middle joint
of the arm support link while raising upward on the arm. A
stop limits upward motion of the arm to a point parallel to
the plane of the back. Lowering the arm automatically locks
it in place against vertical motion in either direction.
3.8. Footrest
3.8.1. The footrest may be retracted by lifting near its outer
edge. When fully retracted the footrest will stay in place.
3.9. Headrest
3.9.1. The No. 26 headrest is the standard headrest for
the Model FX920 Chair.

3.9.2. Operation-No. 26 Headrest
3.9.2.1. The No. 26 headrest is designed so it can be
operated with just one hand. To unlock, squeeze the clear
plastic actuator into lock housing. This will allow both pivots
of the articulating arm to rotate so the headrest can be
moved to a new desired position. Once in the new position,
release the actuator. Make sure the actuator expands to its
original position fully exposing black dot on handle to insure a
positive lock. The headrest pad is free to rotate at all times.

SAFETY/SHUTDOWN

4. PROGRAMMING THE CHAIR
The items described in Section 4. are built-in features of the
chair. Only those users who wish to utilize these features need
to be concerned with this Section. The chair will operate as
previously designed if these features are not used. The chair
can be programmed in the same fashion from either switch
located on the chair back.
4.1. Safety/Shutdown Feature
The chair has a built-in Safety/Shutdown feature. This feature
causes the chair to shutdown or become inoperable. This
feature prevents unauthorized use of the chair. (See Figure
2).
4.1.1 To ENTER Safety/Shutdown Mode
4.1.1.1 Depress and HOLD either STOP switch.
4.1.1.2 With the STOP switch depressed, depress the
LOWER BASE switch on the same side of the chair back.
4.1.1.3 A two second beep will be heard to indicate the chair
will NOT move if any additional switches are depressed.
4.1.1.4 The LED’s on the Membrane Switches will blink every
three seconds while in Safety/Shutdown Mode.
4.1.2 To EXIT Safety/Shutdown Mode, repeat the
above sequence.
4.1.2.1 Depress and HOLD either STOP switch.
4.1.2.2 With the STOP switch depressed, depress the LOWER
BASE switch on the same side of the chair back.
4.1.2.3 A two second beep will be heard to indicate the chair
is functional, and movement of the chair WILL OCCUR when
another switch is depressed.
4.1.2.4 The LED’s will come back on when the chair becomes
operational.
4.2. Individual Programming of the RAISE TOP,
RECLINE TOP, RAISE BASE, and LOWER
BASE switch located on the Chair Back or
Footswitch. (See Figure 2 & 3).
4.2.1 These individual switches may be programmed to
function in two ways. If the movement of the chair STOPS
when the switch is released, this is called the MOMENTARY
MODE of operation. If the movement of the chair continues
after the switch is released, this is called the MAINTAINING
MODE of operation. The factory designed setting for the
RAISE TOP and RECLINE TOP switches located on the chair
top is MAINTAINING MODE. The factory designed setting for
the RAISE BASE and LOWER BASE switches located on the
chair top is MOMENTARY MODE. If changed, the new settings
will remain permanent as long as main power remains applied
to the chair and will apply to the similar function on the other
side.
4.2.2 To change these settings the chair must be placed in
Setup Mode. Once in Setup Mode, depressing one of these
switches will change its present setting from MOMENTARY
to MAINTAINING or from MAINTAINING to MOMENTARY.
Depressing a switch repeatedly will cause the setting to toggle
between the two modes of operation.
4.2.3 To ENTER Setup Mode and change current
settings
4.2.3.1 Depress and HOLD either STOP switch.
4.2.3.2 With the STOP switch depressed, depress the AUTO
switch on the same side of the chair back.
4.2.3.3 A one second beep will be heard to indicate you
have ENTERED Setup Mode. The LED’s will blink on and off
while in Setup Mode.
4.2.3.4 Depress any of the following switches (including
footswitch), one at a time, to toggle its current setting - RAISE
TOP, RECLINE TOP, RAISE BASE, OR LOWER BASE. When
the switch is depressed, a SHORT beep (0.25 seconds) will
indicate the switch is now in MOMENTARY MODE of operation.
A LONG beep (1.05 seconds) will indicate the switch is now
in MAINTAINING MODE of operation.
4.2.3.5 When nished programming the chair, the chair MUST
be taken out of Setup Mode.
4.2.4 To EXIT Setup Mode, repeat steps 1 & 2
above.
4.2.4.1 Depress and HOLD either STOP switch.
4.2.4.2 With the STOP switch depressed, depress the AUTO
switch on the same side of the chair back.
4.2.4.3 A one second beep will be heard to indicate the chair
has EXITED Setup Mode. The LED’s will come back on.

CLEANING AND MAINTENANCE
Cleaning the Upholstery
When cleaning upholstery, it is suggested that you use all
recommended commercial cleaning agents in an inconspicu-
ous spot to check for potential damage to the upholstery
material before applying to the entire area to be cleaned.
Day to Day soil:
Remove ordinary dirt and smudges with a mild soap and
warm water solution. Dry with a soft, lint-free cloth or towel.
For more difcult stains, use of a stronger detergent is
recommended; however, follow the detergent manufacturer’s
instructions closely.
Disinfecting Material:
In order to disinfect, use a 1:9 solution of bleach and water (1
part bleach to 9 parts water). Wipe surface with damp cloth
then rinse with water immediately, using a damp cloth.
Special cleaning problems:
The following methods are recommended to clean stains
on PreFixx-protected vinyl upholstery. Most stains will be
removed when these cleaning agents are used in the fol-
lowing order.
Type 1 Cleaners: Nonabrasive household cleaners to be
used with water and a soft cloth.
• Formula 409~All-Purpose Spray Cleaner
• Fantastik® Spray Cleaner
• Other similar household cleaners and bleaches
Type 2 Cleaners: Solvent-type cleaner to be liberally ap-
plied with a soft cloth. Dry area with another cloth, rinse
with clean water and dry.
• Rubbing alcohol (isopropyl alcohol)
• Lighter uid (naphtha)
Type 3 Cleaners: Strong, active solvent cleaners such as
nail polish remover (acetone/water) to be applied with a soft
cloth. Stain should be removed with less than six (6) rubs; if
stain persists after six rubs, contact manufacturer. Dry area
with another cloth, rinse with clean water and dry.
CAUTION- These solvents are highly
flammable. Exercise proper care in cleaning
and notify personnel in area of danger. Wear
rubber gloves during all cleaning activity. Use
caution in cleaning around buttons, stitching
and wooden or other decorative trim, since
these solvents could seriously damage such
areas.
PRÉCAUTION: Ces solvants sont extrêmement
inflammables. Faites très attention lors du
nettoyage et avisez le personnel dans la
zone de tout danger. Portez des gants de
caoutchouc durant toute activité de nettoyage.
Faites attention en nettoyant autour des
boutons, des coutures et autres finitions de
bois ou décoratives, puisque ces solvants
pourraient endommager sérieusement ces
endroits.
Cleaning Painted Surfaces
The painted metal surfaces are covered in durable, powder-
coated paint which is resistant to scratching and scufng.
It may be cleaned with a clean cloth dampened with mild,
soapy water or equivalent household product that uses spray
application.
Recommended Infection Control Products
The disinfectant/cleaner products that we have tested and
recommend for our upholstery, painted items and plastic
covers are as follows.
• Cavicide® Hospital Disinfectant
• Precise® Hospital Foam Cleaner Disinfectant
CAUTION - Follow manufacturer’s directions
forconcentrationandapplicationofdisinfecting
cleaner. Avoid prolonged application of any
disinfectant/cleaner products, because
they may cause staining or discoloration of
material.
PRÉCAUTION: Suivez les instructions
du fabricant pour la concentration et
l’application de nettoyeurs désinfectants.
Évitez une application prolongée de tout
produit désinfectant/nettoyant, parce que
ceux-ci pourraient causer des taches ou une
décoloration du matériel.
WARNING: REFER TO LOCAL OR
HEALTHCARE PROFESSION GUIDELINES
FOR SELECTING EFFECTIVE INFECTION
CONTROL PRODUCTS.
AVERTISSEMENT : SE RÉFÉRER
AUX DIRECTIVES LOCALES OU DES
PROFESSIONS DE LA SANTÉ POUR
SÉLECTIONNER DES PRODUITS DE
CONTRÔLE D’INFECTION EFFICACES.
