of these switches is released. If you want the
motion of the Chair to CONTINUE after either of
these switches is released, then see Section 4
for programming instructions.
REMARQUE : Les interrupteurs RAISE (LEVER) et
LOWER (BAISSER) la base sur l’interrupteur au pied

3.4.3. To raise the Armrest simply lift Armrest to the stop
parallel to Chair back.
CAUTION: This exam Chair is designed
for use in a specific position called the
Intended Use Position. Prior to reclining a
patient, ensure the Chair Back is aligned
with the Chair’s power receptacle and
that the Chair Swivel is locked. The safe
working load is reduced if the Chair is
swiveled away from this Intended Use
Position, and may result in insufficient
stability.
GRAB BAR
RELEASE LEVER PRÉCAUTION : Cette chaise d’examen
est conçue pour utilisation dans une
position spécifique appelée la position
d’utilisation prévue. Avant d’incliner un
patient, assurez-vous que le dossier de
la chaise est aligné avec le réceptacle
d’alimentation de la chaise et que le pivot
de la chaise est verrouillé. La charge
de travail sécuritaire est réduite si la
chaise est tournée hors de sa position
d’utilisation prévue et cela pourrait causer
une stabilité insuffisante.
CAUTION-This exam Chair is designed
for use with a specific maximum patient
weight as a static (non-moving) load.
Sudden weight shifts or impact loads
can exceed the safe static load rating of
this Chair, and may result in insufficient
stability.
PRÉCAUTION : Cette chaise d’examen
est conçue pour utilisation avec un poids
de patient maximum spécifique comme
charge statique (sans mouvement). Les
déplacements de poids soudains ou les
charges dynamiques peuvent excéder
la norme de charge statique sécuritaire
de la chaise, ce qui pourrait causer une
stabilité insuffisante.
CAUTION-This exam Chair is designed
for use with a patient properly positioned
in the Chair. Prior to reclining the Chair,
ensure that the patient is seated in the
Chair and that the patient position does
not move to an extreme position either
toward the head of the Chair or toward
the foot of the Chair, since this may result
in insufficient stability.
PRÉCAUTION : Cette chaise d’examen est
conçue pour utilisation avec un patient
correctement positionné dans la chaise.
Avant d’incliner la chaise, assurez-vous
que le patient est assis dans la chaise et
que la position du patient ne se déplace
pas vers une position extrême soit vers
la tête, soit vers le pied de la chaise,
puisque cela pourrait causer une stabilité
insuffisante.

4.1. Fuse Replacement (AC Input Module)

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
applied with a soft cloth. Dry area with another cloth, rinse
with clean water and dry.
• Rubbing alcohol (isopropyl alcohol)
• Lighter uid (naptha)
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:Followmanufacturer’sdirectionsfor
concentration and application of disinfecting
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.
