INTENDED USE
APPLICATION
The versatile Invicta IPC-S and IPC-T wheelchairs, have been designed specifically
for younger users with a range of disabilities. However, consideration must always
be given to certain aspects of powered wheelchair use, to ensure correct and safe
operation.
The user’s age, their physical and psychological capabilities and their physical
weight, i.e. Max.100Kg where no vehicular transportation is required, or 50Kg
where the occupant is to be transported in their wheelchair, in a suitably adapted
motor vehicle.
The use of a powered wheelchair is not recommended for persons with
strong balance disorders, severe limitations in cognitive abilities or reduced
or inadequate eyesight
The environment where the wheelchair is to be used also plays a large part in the
safe use of the wheelchair, serious consideration must be given to aspects such as
transferring to and from the wheelchair, general wheelchair access and facilities
within the home and school.

GENERAL SAFETY INSTRUCTIONS
These Instructions for Use should be available to the User, or their
representative at all times.
In order for the User to gain maximum advantage from the Invicta wheelchair and
for it to be used as safely as possible, it is essential that the initial setting-up and
adjustment of the wheelchair components, together with the tuning characteristics
of the power drive controller, are carried out by suitably qualified personnel who will
ensure that the wheelchair is set to meet your individual requirements.
Where the User is taking medication, the prescribing doctor / physician should be
consulted to confirm that it is safe to drive the wheelchair whilst taking the
medication.
The wheelchair should never be driven by anyone under the influence of alcohol or
illegal drugs.
As the maximum speed of the Invicta IP models is 4mph they are therefore suitable
only for indoor use and for limited outdoor use on footpaths and designated
pedestrian areas. They are NOT suitable use on the public highway except for the
purpose of crossing the road at pedestrian crossings or wheelchair suitable points
where the kerbs have been lowered.
Wherever possible, traversing driveways, slopes and ramps should be avoided.
The maximum slope / ramp angle for driving up or down is 10°.
The maximum obstacle climbing height, is 50mm (2 inches).
To exceed either of these limits could severly affect the overall stability of the
wheelchair, causing it to tip and lead to possible injury to the User.
Do NOT exceed the maximum User weight limits of 100Kg (15.7stones) for nonvehicle transportable Users, or 50Kg (7.8 stones) for Users who are transported in
their wheelchair in a motor vehicle.
It is recommended that new powered wheelchair Users, take time to build up their
driving skills. Patience and Practice will be required by both Users and their
experienced Assistants, while learning various manoeuvres.
Navigating day to day obstacles with confidence, will be achieved with appropriate
training and practice.
The User should also be aware that, as the powered wheelchair operates very
quietly and is capable of travelling faster than some walking speeds, these aspects
could create a hazard to others especially in congested pedestrian areas.
Users of the IPC-T model Invicta with Power Tilt, should also be aware of the
following potential risks:-
1. There is a possibility of fingers being trapped, between the Sidearm Mounting
Bracket and Chassis Frame when the Seat is being lowered from a tilted
position. A Warning Label is applied to the Chassis Frame in this area to
warn of the risk.
2. There is also a potential risk of finger trapping at the rear of the Seat where the
Seat mounting brackets run on the actuator guides. A Warning Label is applied
to the Chassis Frame in this area to warn of the risk.

Page 10
Electro-Magnetic Interference
The Invicta IPC-S and IPC-T model wheelchairs have been successfully tested in
accordance with international standards as to their compatibility with (EMI)
regulations. However, electromagnetic fields, such as those generated by radio and
television transmitters and cellular phones, can influence electrically powered
vehicles.
To reduce the danger of Malfunction due to Electromagnetic Interference, the
following points should be noted:-
Portable communication devices such as Radio Transceivers, Cellular Phones
and “Walkie-Talkie” devices should not be operated in close proximity to the
wheelchair, whilst the wheelchair is “Swiched On”
Avoid getting into close range of powerful radio and television transmitters.
Should the wheelchair be set into unintentional motion, or the electro magnetic
brakes released unexpectedly, “SWITCH OFF” the wheelchair immediately.
By adding electrical accessories to your wheelchair or modifying the original
equipment electrical system could change the wheelchair’s susceptibility to EMI.
Both Invicta models are currently able to provide an immunity level of 20V/m
which should protect against common sources of EMI.
Any occurances of unintentional movement of the wheelchair, including
uncontrollable directional control, or unexpected release of the electromagnetic
brakes, should be reported to your wheelchair supplier as soon as possible.
Environmental Conditions
Environmental conditions may affect the safety and performance of your power
wheelchair. Water and extreme temperatures are the main elements that can cause
damage and affect the power drive performance.
Rain, Sleet and Snow — If exposed to water, the power drive system is
susceptible to damage to electrical or mechanical components. Water ingress
can cause electronic malfunction or promote premature corrosion of electrical
components.
DO NOT leave the wheelchair parked outside in the rain.
DO NOT park the wheelchair in a washroom/bathroom while taking a shower.
Temperature — Some parts of the power wheelchair are susceptible to changes
in temperature. The Controller can only operate within a temperature range
between 18°F (-8°C) and 122°F (50°C).
At extreme low temperatures, the batteries could freeze and the wheelchair may
not be able to operate. In extreme high temperatures it may operate at slower
speeds due to a safety feature within the Controller that prevents damage to the
drive motors and other electrical components.
Care must also be taken in hot weather. DO NOT leave the wheelchair parked
where it will be exposed to the sun, as the surfaces of the wheelchair can absorb
the heat and therefore become very hot to touch.
10
Page 11
Transferring to and from the Wheelchair.
Before attempting to transfer into the wheelchair, the following points should be
noted:-
To reduce the efforts sometimes required, to complete the transfer into a
wheelchair, it should be positioned as close as possible to the User’s position.
The power must be “Turned Off”.
The Free Wheel Lever set to the “Drive” (Forward) position and both Parking
Brakes applied. See Figs. 1 and 2.
Remove Armrests if required.
Raise both Footplates or swing-away both hangers. See Figs. 1 and 3.
Stability of the stationary wheelchair can be improved by pointing both Castor
Wheels towards the direction of transfer.
NOTE: Never use the wheelchair footplates to stand on during transfers.
Reaching and Leaning when seated in the Wheelchair.
The Pelvic Belt (Lap Belt) supplied with the wheelchair, should be the first thing
to be secured after entering the Wheelchair.
The User should never attempt to reach upwards or outwards for any object
which would require lifting their body weight off the wheelchair seat as this would
change the centre of gravity and could therefore affect the wheelchair stability.
Leaning forwards by the User, in an attempt to reach something on the floor in
front of the wheelchair, can also create a serious instability situation and must not
be attempted.
Excessive leaning sideways should also be avoided as this can affect the overall
lateral stability of the wheelchair, which could result in injury to the User, either by
tipping the wheelchair or becoming an obstacle to other people in congested
areas.
NOTES:
1. Do not hang heavy loads on the wheelchair backrest frames or push-handles
as this can seriously affect the rearward stability, especially when taking up
the drive on an incline (dynamic stability).
2. Correct use of the height adjustable rear Anti-Tippers, supplied as standard
with Invicta IPC-S and IPC-T models, is very important and these should be
positioned according to the environmental conditions where the wheelchair is
to be driven. (See page 35 relating to positioning Anti-Tippers)

Transportation of the Occupant, in a suitably adapted motor vehicle, when seated in
their wheelchair. Models IPC-S and IPC-T
Both Invicta models, IPC-S (Tested as
P17R) and IPC-T (Tested as P17RT) have
been successfully tested, in the forward
facing mode, to ISO 7176 part 19, on the
1st September 2010, at the Transport
Research Laboratory, Berkshire, UK.
The tests were carried out using fixed 4point wheelchair restraint systems and
fixed 3-point occupant restraint systems,
tested to ISO 10542 and supplied by
Q-Straint.
The front and rear wheelchair restraint tiedown points, are clearly marked on the
chassis by standard Karabiner signs and
these are the only positions to be used in
transportation.
Under No circumstances should the wheelchair Lap or Pelvic Belt be used as the sole
method of occupant restraint.
The safe occupant weight limit for
transportation in the Invicta is 50Kg.
Although the Invicta Wheelchair “Crash
Tests” were carried out without using
Headrests, the use of these devices should
be optional, with the decision as to whether
it is necessary, being made by a suitably
qualified person following an individual risk
assessment.
The Wheelchair with Occupant should be positioned forward facing, centrally, over the tiedown tracks located on the transporting vehicle floor. Both Parking Brakes should be applied
and the Drive Selector Lever set to the “Drive” (forward position), as indicated in Fig.5
The WTORS (wheelchair tie-down and occupant restraint system) should be connected and
used in accordance with the manufacturers recommendations, see Fig.4 as an example.

recommended that both Batteries are
replaced at the same time and ideally,
they should be fully charged by the
supplier before installation.
Ensure Main Battery Cables are correctly
connected to the Batteries and the
terminal screws are fully tightened. Fig.26
Re-installation of the Batteries is by the
reverse, step by step, of the removal
procedures.
On completion of reassembly and final
connection of cables, ensure the Drive
Selector Lever Fig.2, is set in the forward
“Drive” position and the Manual Parking
Brakes are applied. Switch “ON” the
power at the Remote Controller Fig.20,
(ensure Joy Stick is in the central
position) to check the Battery charge
level on the indicator. Figs.27a, b and c.
Each Battery Box is fitted with an
overload Reset Button, Figs 26a and 26b.
As these are safety devices, if either
device trips-out more than once, then try
to note what was operating when it

The Battery Gauge
The Battery Gauge is to let you know how much charge is left in your Batteries.
The best way to use the gauge, is to learn how it behaves as you drive the
wheelchair. Like the fuel gauge in a motor car, it is not totally accurate, but it will
help to avoid running out of “charge”.
The gauge works in the following way:-
When you switch the system “ON”, the gauge shows an estimate of the remaining
Battery charge. Figs.27a, 27b and 27c
The Battery gauge will however, gives a more accurate reading, approximately one
minute after you start driving the wheelchair.
DO NOT operate the control system if the Batteries are nearly discharged,
as failure to comply with this warning may leave the User stranded in an
unsafe position i.e. in the middle of a road or busy shopping walkway.
Neither RMS Ltd, or PG Drives Technology, will accept any liability for loss or
damage of any kind arising from failure to comply with this WARNING.
IMPORTANT INFORMATION:
The Battery Gauge also has built-in status indication with the following signals:-
Battery Gauge is Steady—This indicates that all is well.
Battery Gauge Flashes Slowly–The control system is functioning correctly, but
you should charge the batteries as soon as possible.
Battery Gauge Steps Up–The wheelchair Batteries are being charged. You will
not be able to drive the wheelchair, until the Charger is disconnected and you
have switched the Controller “OFF” and then back “ON” again.
Battery Gauge Flashes Rapidly (even with the Joystick released) - The control
system safety circuits have operated and the control system has been prevented
from allowing the wheelchair from moving. This indicates a system trip, i.e. the
VR2 has detected a problem somewhere in the wheelchair’s electrical system.
Please follow this procedure:-
1. Switch “OFF” the control system.
2. Make sure that all external cable connections on the wheelchair are correctly
connected and secure.
3. Check the Battery condition.

Charging the Batteries
Only use the Charger supplied with the wheelchair.
Your Charger is equipped with dual voltage, (i.e.115v and 230v)
ensure the Charger is set to the appropriate voltage compatible
with your Mains Supply, Fig.28a.
The Charger is intended for interior use only and must be
protected from moisture. Always charge your Batteries in a well
ventilated area.
If the wheelchair is to be taken out of service for a long period of
time, it is recommended that arrangements are made for the Batteries to be
charged at least once every month.
Depending on the condition of the Batteries, charging
can take between 4 and 10 hours to fully charged. This
will be indicated by the light status on the charger end
panel, changing to green.
NOTE: Charging for longer than necessary will not
harm the Batteries, however, it is recommended that
the Batteries are charged for 8 to 10hours after daily
use, but not charged continuously for more than
24hours.
Charging Instructions
Park your wheelchair close enough to a Mains power
socket outlet, to enable the Charger mains cable to
reach the socket and the Charger power cord (with
round plug) to safely reach the socket on the underside
of the Remote Controller, Fig.28b.
Connect the Charger Power Cable to the Remote Controller, Fig.28b and plug
Mains cable into the Mains 240v socket. Switch-on at the socket.
One Orange and one Green light will illuminate when the Charger is switched “ON”,
Fig.29a.
When the Orange light changes to Green, the
charging process is complete, Fig.29b
The Green power light will stay “ON” until the
power is disconnected and the Charger power
cord is removed from the wheelchair.
Please also refer to the instruction sheet
supplied with Battery Charger.
Disposal and Recycling of used Batteries and Electrical Equipment
Batteries and Electrical Equipment must always be correctly recycled and
under no circumstances should they be disposed of with domestic refuse.
You can assist in helping to preserve the environment by returning your
used Batteries or Electrical Equipment to your local approved collection
and recycling point, which is normally run by your local council.
For information on the location of your nearest Battery recycling point,
please contact your local government authority.
RMS Ltd is an environmentally aware supplier that complies wherever
possible with the WEEE Directive 2002/96/EC.

REMOTE CONTROL OPERATION
Introduction
Operation of the VR2 wheelchair Control System, is simple and easy to understand.
The Control System incorporates State-of-the-Art electronics, the result of many
years of research, to provide you with ease of use and very high level of safety.
In common with other electronic equipment, correct handling and operation of the
unit will ensure maximum reliability.
Please read the information in this chapter carefully—It will help you to keep your
wheelchair reliable and safe.
General
Avoid knocking your Control System and especially the Joystick. Be careful not to
strike obstacles with the Control System or Joystick when you drive. Never drop the
Control System.
When transporting your wheelchair, ensure the Control System is well protected
and avoid damage to cables.
Your Control System uses industrial-grade components throughout, ensuring
reliable operation in a wide range of conditions. However, you will improve the
reliability of the Control System if you keep exposure to extreme conditions to a
minimum.
Do not expose the Control System or its components to damp for prolonged
periods.
If the Control System becomes contaminated with food or drink, this should be
cleaned off as soon as possible.
Clean the Control System and the Joystick with a cloth dampened with diluted
detergent. Be careful when cleaning the Joystick—Ensure the power is turned
“OFF”. Never use abrasive or spirit-based cleaners.

Symbol Identification and Operational Information.
Refer also to Figs.30a and 30b on page 26 and the diagnostic table on page 28.
Symbol Details
The Battery Gauge shows that the wheelchair is switched
“On”. It also indicates the operating status of the
wheelchair.
The “ON / OFF” Button is operated by depressing the
button once to switch the power “ON” and depressing the
button again to switch the power “OFF”.
When switched “ON”, this applies power to the Control
System electronics, which in turn supplies power to the
wheelchair’s motors.
Unless there is an emergency, DO NOT use the “ON /
OFF” button to stop the wheelchair, as this could shorten
the life of the drive components.
The Joystick primary function is to control the speed and
direction of the wheelchair. The further you push the
Joystick from the centre position, the faster the wheelchair
will move. When the Joystick is released, the brakes are
automatically applied.
If the wheelchair is fitted with an actuator, the Joystick may
also be used to select the actuator direction.
The Horn Button will sound the horn when the button is
depressed.
The Profile Indicator is an indicator that shows the
selected drive profile. There may be up to five profiles
available, this depends on the programming of the Control
System.
The Maximum Speed / Profile Indicator is a gauge that
shows the maximum speed setting for the wheelchair or, if
the Control system is programmed for drive profile
operation, the selected drive profile.
Speed Profile Buttons—To increase the speed profile,
depress the Right-hand Button once for each speed range
increase. The indicator lights will inform you of the current
level range setting.
Depressing the Left-hand Button will decrease the speed
range one level for each depression.
The Actuator Buttons allow the User to depress either
Button to enter the adjustment mode and this will be
indicated by illumination of both actuator LEDs.
The Seat Tilt actuator can now be operated by the forward
and rearward movement of the Joystick. Fig.30b only

Programming the Remote Controller
The VR2 Controller is fully programmable to suit individual requirements and should
therefore be set up for the User, by a suitably qualified person using the appropriate
programming devices, at the time of hand-over.
NOTE: Programming should only be carried out by Healthcare Professionals
with in-depth knowledge of the PGDT Control Systems. Incorrect
programming could result in an unsafe set-up of the wheelchair for the User.
Neither PGDT or RMS Ltd will accept any liability, for losses or injury caused
by incorrect adjustments made, by non-suitably qualified persons, where the
system is altered from the original factory pre-set values.
Driving the Invicta Wheelchair — General
Make sure the Control System is securely
mounted and that the Joystick position is set
correctly for the User. The hand or limb to be
used to operate the Joystick, should be
supported, i.e. by the sidearm pad. Never use
the Joystick as the sole support for your hand or
arm as wheelchair movements and bumps
could affect your control. Both the Sidearm and
Remote Controller positions are adjustable to
suit individual requirements. Fig.31.
To set the correct Sidearm height, slacken
Sidearm Height Adjustment Thumb-screw,
sufficient to enable the Sidearm to be
repositioned upwards or downwards.
Retighten Thumb-screw, ensuring the screw
thread engages into the required positioning
hole.
To set the Remote Controller in the correct position, slacken both locking grub-
screws, slide Controller Stem forwards or rearwards, then secure in the required
position by retightening grub-screws sufficiently to prevent any movement.
Getting Ready to Drive your Invicta
Operate the “ON/OFF” switch. The battery gauge will blink, then remain “ON”
after a second.
Check that the maximum speed control is set to a level which suits you.
Push the Joystick to control the speed and direction in which you want the
wheelchair to travel.
NOTE: If you push the Joystick before, or just after, you switch the Control
System “ON”, the battery gauge will ripple up and down and the wheelchair
will not be allowed to move. You must release the Joystick to resume normal
operation.
If you do not release the Joystick within five seconds, the wheelchair will not
be able to move, even if release the Joystick and push it again. The battery
gauge will then flash rapidly.
You can re-set this condition, by switching the Control System “OFF” and
then back “ON” again.
If the battery gauge continues to flash rapidly, this means that the VR2 has
detected a problem somewhere in the wheelchair’s electrical system. Refer to
the Self-Help information on page 28.

Driving Technique
The Control System interprets your Joystick movements and produces appropriate
movements of your wheelchair. You will need very little concentration to control the
wheelchair, which is especially useful if you are inexperienced. Normal practice is to
point the Joystick in the direction you want to go and the wheelchair will “home-in”
on the direction the Joystick is pushed.
The further you push the Joystick away from the rest position, the faster the
wheelchair will go. Releasing the Joystick will stop the wheelchair. The intelligent
Speed Control System minimizes the effects of slopes and different types of terrain.
It is recommended that the new User is allowed, with supervision, to practice
manoeuvring in an area where there are no other people, pets or obstacles.
There are always risks and hazards attached to driving a powered wheelchair.
The risks however, can be reduced considerably, by being aware of what may
become a hazard and taking alternative measures to avoid this.
Here are some examples:-
The maximum obstacle climbing height is 50mm, therefore, care should be taken
especially when driving outdoors. Look for dropped curbs and signs indicating
wheelchair access.
Traversing slopes should be avoided wherever possible, but should it become
necessary, be aware that when driving across dropped curbs or driveways for
example, the angles can vary considerably which could have an affect on the
overall lateral stability of the wheelchair and occupant. NEVER park your
wheelchair transversely across a slope.
Avoid slopes or ramps over 12 degrees, as above this could affect the dynamic
stability of the wheelchair. NEVER attempt to negotiate steps or stairs.
Do not drive your wheelchair in places or on surfaces where a loss of wheel grip
could occur, i.e. grassy slopes, snow or ice covered surfaces.
Avoid causing serious damage to your wheelchair by impacting objects at speed
with the front Castor Wheels and/or Footrests.
Care must always be taken when using the wheelchair indoors or when
manoeuvring in confined spaces. For example, the speed setting should be
reduced to a level which the driver is comfortable with. See Speed Profile
Buttons page 27. REMEMBER one indicator light displayed is the lowest speed
range, with five indicator lights displayed being the fastest speed range.
Do not drive your wheelchair if the Control System shows any signs of not
behaving as it normally does. i.e. In the event of the wheelchair moving in an
unexpected way, RELEASE the JOYSTICK, this will stop the wheelchair under
any circumstances.
NOTE: The Manual Parking Brakes should never be used as a method of
slowing down or stopping a moving wheelchair.
Familiarise yourself as soon as possible, with your needs regarding transferring
and toileting.
Users of the Invicta IPC-T, (Tilt-in-Space model), should also be aware of the
following safety feature:-
Whilst this model is able to offer 40° of powered centre of gravity Tilt-in-Space, to
safeguard the rearward stability and assist with safer visibility when manoeuvring,
the wheelchair Control System has an inbuilt inhibitor, which prevents the
wheelchair from being driven, if the Seat Unit exceeds 15°of tilt. Therefore if you
are using the wheelchair in a tilted position and wish to move to another location,
it may be necessary for the Seat Unit to be lowered before being able to move.
Page 31

Your powered wheelchair is designed for minimum maintenance. However, like any
motorized vehicle, it will require routine checks and maintenance. To ensure your
Invicta wheelchair continues for many years of trouble-free operation, it is
recommended you follow the maintenance checks as scheduled below:-

Manual Parking Brake Adjustment
As the efficiency of the Manual Parking
Brakes can be affected by tyre wear on
the rear drive wheels, adjustment is
made available on each Brake Mounting
Bracket. Fig.32.
NOTE: Care must be taken to maintain
correct alignment of the Brake
Mechanism, when carrying out this
adjustment, as incorrect positioning
could result in the Brake Mechanism
being ineffective, or fouling the Drive
wheel tyre.
Tools Required:-
“T” 5mm Hexagon Key.
With the Brake lever set in the fully
“OFF” (rearward) position, slacken
both screws on the Manual Brake
Mounting Clamp, just sufficiently to
enable the Brake mechanism to be re-set.
Re-position the Brake mechanism to give 19mm (¾") clearance between the
Brake Bar and the tyre. Avoid moving the Mounting Clamp from it’s original
position.
With the Brake mechanism held in this position and while ensuring the Brake
Bar is at 90° to the tyre, retighten both Brake Mounting Clamp screws, sufficiently
to prevent any movement. Repeat this procedure for the opposite side.
Apply both Parking Brakes before setting the wheelchair Drive Mode Lever to
“Free wheel” (rearward direction), then confirm that it is not possible to move the
wheelchair with only the Parking Brakes applied.
Checking security of Rear
Drive Wheels. (Fig.33)
Tools Required:-
Suitable Torque Wrench and socket with
6mm Hexagon Bit.
13mm Spanner.
Security of the Rear Drive Wheels,
should be checked at 6 monthly
intervals, (more frequently may be
required for very heavy users).
Failure to do so, could result in
premature wear of the wheel mounting
holes and motor drive flanges.
Screws should be tightened evenly
to 27Nm (20ft/lbs), whilst holding the
corresponding nuts at the rear of the

Checking the Front Castor Forks and
Wheels
With the wheels lifted clear of the ground,
check the Castor Forks for excess
movement in the swivel bearings and for
smooth turning.
This is important—as unsmooth turning
by the Castor Wheels can seriously affect
the wheelchair steering and
manoeuvring.
Also check that the Castor Wheels spin
freely and without axial run-out. Fig.34
If there is any doubt about the
movement in either the Castor Forks
or the Wheels, contact your repairing
agent as soon as possible.
Checking the Drive Motor Brushes
It is recommended that after the first 12
months of use, the Drive Motor Brushes
should be checked by your service
agent and thereafter at 6 monthly
intervals to maintain peak Motor
performance.
Each Drive Motor is fitted with two
Brushes, however, as access to the
inner Brush Retaining Cap is limited by
the Battery Carrier Frame, inspection of
the outer Motor Brushes should give an
indication of the wear on both Brushes.
Tools Required:Flat-bladed Screwdriver,
(blade width = 4 to 6mm).
To inspect the outer Brushes, unscrew
the Brush Retaining Caps, Fig.35 and
withdraw the Brushes from their holders.
Measure the length of each Brush to
ensure that they exceed the minimum
length of 10mm. If less than 10mm
replace Brushes at this time. Fig.36
NOTE: Both Brushes must be replaced
at the same time, on each Motor.
Replacement of the inner Brushes will
require removal of the complete Motor.

Anti-tip Devices
Height adjustable Anti-tip devices are supplied
as standard with the Invicta Powered
Wheelchair.
For normal use, it is recommended that the Antitip devices are set to the highest position, Fig.37.
This will give a ground clearance between the
jockey wheel and the floor of 40mm. In turn, this
will allow the wheelchair to be able to climb an
obstacle of up to 50mm.
To alter the Anti-tip height, pull the Spring-loaded
Locking Pin rearwards to disengage the Anti-tip
Stem. Re-set to required height and re-engage
Locking Pin.
Retaining Lap-Belt
The standard Lap Belt supplied with the Invicta
is the RMS PB002 with single “Pull-tight” plastic
buckle.
Separate the Belt at the main buckle by
depressing the locking tongue, Fig.438.
With the User seated, route each end of the Lap
Belt up and over the User’s hips and round to the
front of the User, connecting the main buckle in
the centre of their lap.
Adjustment is made by pulling the “free-end”
through the buckle to the required position.
Overall belt length can be adjusted at the Tri-slot
mountings located at each end of the Belt where
they are attached to the Seat frame.
NOTE: If it becomes necessary to change the
Backrest angle, it may also be necessary to re-position the Lap Belt Mountings,
utilising an alternative vacant hole on the Backrest Connecting Bracket. Fig.18

Keeping the Invicta Wheelchair Clean
The wheelchair paintwork should be cleaned on a monthly basis by wiping with a
damp cloth and mild detergent. Polishing with good quality auto wax will help to
preserve the Frame appearance.
The upholstery can be cleaned by lightly sponging using warm soapy water with a
little disinfectant added.
DO NOT USE any scrubbing agents.
DO NOT USE high-pressure cleaning devices.
DO NOT subject the electronic components to direct contact with water.
Wipe off all cleaned areas with a clean dry cloth and ensure the upholstery is
thoroughly dry before re-using the wheelchair.
The standard Lap Belt with a plastic buckle can be removed from the wheelchair
and machine washed if required. Ensure the nylon webbing is correctly threaded
through the Tri-slot mounting when re-installing.

End of Product Life
Although your Invicta Powered Wheelchair has been designed to provide you with a
long and trouble-free life, it is inevitable that wear, tear and continual usage will
eventually render the device unusable or beyond economical repair.
RMS Ltd, recommends that the average usable life-cycle expectancy of the Invicta
Powered Wheelchair is five years, assuming that it has been maintained according
to the manufacturer’s recommendations.
When the time comes to replace your wheelchair, please remember to dispose of
the device responsibly and recycle as many parts as possible.
Where your wheelchair has been supplied by an NHS Wheelchair Service, they, or
their Appointed Service / Repair Agent, can arrange for safe disposal.
If your wheelchair is privately owned, then it is the owners responsibility to dispose
of the device at the end of its useful life cycle, in a safe and proper manner.
Your local Council will normally be able to assist with this.
