Repair or Service Information
Except for programming, O NOT service or adjust the wheelchair while occupied,
unless otherwise noted.
After ANY adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may occur.
Before adjusting, repairing or servicing the seating system, ALWAYS turn the wheelchair
power OFF, otherwise, injury or damage may result.
Pinch points exist between seat and base frames. Use caution, otherwise injury may occur.
Cables MUST be routed and secured properly to ensure that the cables O NOT become
entangled and damaged during normal operation of seating system.
Cables MUST be secured to the wheelchair frame and/or base with tie-wraps after
servicing is complete. Failure to follow the warnings and instructions listed within this
manual could result in injury to the users, attendants and/or bystanders and/or damage
to the wheelchair.
Cables MUST be secured so there are no loops of excess cable extending away from the
wheelchair. Bundle all excess cable together and secure with a tie-wrap. It may also be
necessary to secure these bundles to the frame and/or base.
ALWAYS test all wheelchair functions after securing the cables to be sure cables O NOT
get pinched, crushed, or strained during operation of the wheelchair.
Operation Information
Invacare products are specifically designed and manufactured for use in conjunction with
Invacare accessories. Accessories designed by other manufacturers have not been tested
by Invacare and are not recommended for use with Invacare products.
O NOT attempt to lift the wheelchair by any removable (detachable) parts. Lifting by
means of any removable (detachable) parts of a wheelchair may result in injury to the user
or damage to the wheelchair.

SECTION 1—GENERAL GUIDELINES
Part No 1114842 5 2G Tarsys®Powered Seating System
Performance adjustments should only be made by professionals of the healthcare field or
persons fully conversant with this process and the driver's capabilities. Incorrect settings
could cause injury to the driver, bystanders, damage to the chair and to surrounding
property.
After the seating system has been set-up/adjusted, check to make sure that the seating
system performs to the specifications entered during the set-up procedure. If the seating
system does NOT perform to specifications, turn the wheelchair OFF IMME IATELY
and re-enter the set-up specifications. Repeat this section until the seating system
performs to specifications. Refer to Reference ocuments on page 2.
Avoid storage or use near external flame or combustible products.
O NOT operate the seating system while on an incline.
O NOT operate the seating system while the wheelchair is moving.
NEVER operate the wheelchair while in any tilted/reclined/back angle position over 20°
relative to the vertical position. If the drive lock-out does not stop the wheelchair from
operating in a tilt position over 20° relative to the vertical position, O NOT operate the
wheelchair. The drive lock-out settings MUST be adjusted.
Pinch points may occur when returning the tilted seat to the full upright position. Make
sure the hands and body of both the occupant and attendants/bystanders are clear of all
pinch points before returning the tilted seat to the full upright position.
O NOT operate tilt seat around children.
O NOT overtighten hardware attaching to the frame. This could damage the frame
tubing.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.
ALWAYS keep hands and feet out from underneath tilt seat - otherwise serious injury
may result.
When on an incline, NEVER leave an unoccupied wheelchair unattended at any time.
Use only SAC, TRSS, TRCM and TAC actuator controls to activate the tilt/recline
functions*. O NOT USE any other actuator controls. Such devices may result in excess
heating and cause damage to the actuator and associated cables and could cause a fire,
death, physical injury or property damage. If such devices are used, Invacare shall not be
liable and the limited warranty is void.
*NOTE: Specific actuator controls are noted for each function or combination throughout this
manual.

Grounding Instructions
O NOT, under any circumstances, cut or remove the round grounding prong from any
plug used with or for Invacare products. Some devices are equipped with three-prong
(grounding) plugs for protection against possible shock hazards. Where a two-prong wall
receptacle is encountered, it is the personal responsibility and obligation of the customer
to contact a qualified electrician and have the two-prong receptacle replaced with a
properly grounded three-prong wall receptacle in accordance with the National Electrical
Code. If you must use an extension cord, use ONLY a three-wire extension cord having
the same or higher electrical rating as the device being connected. In addition, Invacare
has placed RE /ORANGE warning tags on some equipment. O NOT remove these tags.

Each pow r d wh lchair can r sist EMI up to a c rtain int nsity. This is call d its
“immunity l v l.” Th high r th immunity l v l, th gr at r th prot ction. At
this tim , curr nt t chnology is capabl of achi ving at l ast a 20 V/m immunity

radiat d EMI.
Th r ar a numb r of sourc s of r lativ ly int ns l ctromagn tic fi lds in th

Th sourc s of radiat d EMI can b broadly classifi d into thr typ s:
1) Hand-h ld Portabl transc iv rs (transmitt rs-r c iv rs with th ant nna
mount d dir ctly on th transmitting unit. Exampl s includ : citiz ns band (CB)
radios, “walki talki ”, s curity, fir and polic transc iv rs, c llular t l phon s,
and oth r p rsonal communication d vic s. NOTE: Som c llular t l phon s

2) M dium-rang mobil transc iv rs, such as thos us d in polic cars, fir trucks,
ambulanc s and taxis. Th s usually hav th ant nna mount d on th outsid of
th v hicl ; and
3) Long-rang transmitt rs and transc iv rs, such as comm rcial broadcast
transmitt rs (radio and TV broadcast ant nna tow rs) and amat ur (HAM)
radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, D players, cassette players, and small appliances, such as
electric shavers and hair dryers, so far as we know, are not likely to cause EMI problems
to your powered wheelchair.

pow r d wh lchairs and motoriz d scoot rs.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD REDUCE THE
CHANCE OF UNINTENDED BRAKE RELEASE OR POWERED WHEELCHAIR
MOVEMENT WHICH COULD RESULT IN SERIOUS INJURY.
1) DO NOT op rat hand-h ld transc iv rs (transmitt rs r c iv rs), such as
citiz ns band (CB) radios, or turn ON p rsonal communication d vic s, such as
c llular phon s, whil th pow r d wh lchair is turn d ON;
2) B awar of n arby transmitt rs, such as radio or TV stations, and try to avoid

OFF as soon as it is saf ;
4) B awar that adding acc ssori s or compon nts, or modifying th pow r d
wh lchair, may mak it mor susc ptibl to EMI (NOTE: Th r is no asy way
to valuat th ir ff ct on th ov rall immunity of th pow r d wh lchair); and
5) R port all incid nts of unint nd d mov m nt or brak r l as to th pow r d
wh lchair manufactur r, and not wh th r th r is a sourc of EMI n arby.
