Use for intended purposes
(1)
The Fortress Calypso scooter was developed for:
• The transportation of people weighing up to 125 kg
• Use on pavements, footpaths and cycle paths
• Use in and around the house
The dealer must give you clear instructions before you start operating the product independently.
Your first test drives of the Fortress Calypso are best carried out under the supervision of an experienced dealer.
The Fortress Calypso scooter is not classified as a road vehicle and therefore may not be used on the road
(crossing over the road being the only exception).
The Fortress Calypso has a maximum speed of 10 km/h (6 mph).
ENSURE THAT YOU ARE FULLY ACQUAINTED WITH THE CONTENTS OF THIS MANUAL BEFORE
STARTING TO DRIVE THE FORTRESS CALYPSO.
If you use the scooter in a dangerous fashion, or use the scooter for purposes other than those intended,
Handicare will accept no liability for any personal injury or damage to property caused by such misuse.
(1)

declaration, including the manufacturer’s instructions in the sales brochure. In the event of doubt, use is taken to mean the use as construed
from the design, construction and function of a product. The instructions contained in the user manual must also be followed within the scope of
intended use.

General safety rules and regulations
Version 2015v1 9
1 General safety rules and regulations
Handicare accepts no liability for loss or injury caused by not following the safety rules and regulations fully, or
otherwise for loss or injury as a result of negligence during use or when cleaning the scooter and any accessories.
Supplementary safety regulations may apply depending on the specific circumstances for operation or on the
accessories used. Please contact your dealer immediately if you should ascertain any potential hazards when
using the product.
The user of the scooter (see ‘Intended use’) is at all times responsible for following local safety
rules and guidelines.
1.1 Labels and instructions on the scooter
The markings, symbols and instructions on the scooter constitute a part of the safety guidelines for the scooter. For
this reason they may never be covered or removed and must be present and clearly legible for the entire period of
time the scooter is in existence.
Illegible or damaged labels, symbols and instructions must be replaced or repaired immediately. Contact your
dealer in such cases.
1.2 Technical specifications
No changes may be made to the technical specifications.
1.3 Adaptations
Adaptations to components of this product are not permitted.
1.4 Safety
It is of great importance that attention be paid to the following safety regulations for the prevention of accidents and
undesirable situations.
Take extra care when driving on slopes:
•Never remove safety devices, such as the anti-tip wheels.
•Never drive the Fortress Calypso up slopes with a gradient greater than that specified in
section 5.4.3 of this manual.
•Always drive up slopes slowly and take extra care.
•Never descend a slope at full speed.
•Do not drive down slopes covered with loose gravel or with a sandy surface, as one of the back
wheels may slip.
•Do not turn on slopes.
•Never take corners at full speed. Reduce speed before taking a corner.
•When driving up a slope, adopt a position which promotes stability, as described in section
5.4.3 of this manual.
•Ensure that clothing does not trail as this can become entangled in the wheels.
•Ensure that your fingers do not become trapped in the mechanism for adjusting the position of
the steering column.
You must adjust your driving to the prevailing conditions:
•Drive carefully on roads which have become slippery due to rain, black ice or snow!
•Reduce speed in busy surroundings.
•Do not use the scooter on unsurfaced roads.
•Ensure that the Fortress Calypso A does not come into contact with salt water. Salt water is
corrosive and can damage the scooter.
•Ensure that the Fortress Calypso does not come into contact with sand. Sand can find its way
into the moving parts of the scooter, resulting in these parts wearing out unnecessarily
quickly.
•Never drive the scooter while under the influence of drugs, alcohol or prescription medications
which could affect your driving ability.
•Your eyesight must be adequate for you to drive the scooter safely.

General safety rules and regulations
10 Version 2015v1
•If visibility is not ideal, then it is obligatory for the lights to be turned on. The scooter is
equipped with brake lights which illuminate on braking.
•Use the indicator lights only to indicate a change in driving direction.
•Only use the horn for warning pedestrians or other road users of possibly hazardous
situations.
•Never place metal components on top of the batteries. Doing so could cause a short circuit,
leading to damage.
•Do not transport any passengers on the scooter. The scooter has been specifically designed to
transport you alone.
•Do not drive the scooter with the seat backrest angled too far to the rear. This can affect weight
distribution and the stability to the rear of the scooter, in particular when driving up slopes or
over obstacles.
•Ensure that your scooter does not transport a greater load than fits in the basket. Never hang
anything on the tiller.
•Never use the scooter for pulling a trailer. The scooter has not been designed for such use and
doing so can cause serious damage to your scooter.
•Do not stand on the platform in order to reach up to objects.
•Do not position your feet too close to the front wheel and fork when driving. Always keep your
feet on the rubber mat and not up against the front tiller cover.
The scooter is electronically driven. Specific parameters have been factory-set. These settings
have been made in order to ensure that use of the Fortress Calypso is comfortable and efficient
and they can not be changed.
The standard version of your scooter has been tested in accordance with the most stringent
requirements for electromagnetic interference.
If you use a mobile telephone near to a specially adapted scooter, it is advisable to switch the
scooter off first.
Your scooter can affect electromagnetic fields, such as alarm systems. If the scooter’s electronics
are not well shielded, sensitive electrical devices, such as shop alarm systems and garage door
openers, can be affected. The scooter has been tested for such interference. Please report any
problems of this nature to your dealer immediately.
•Beware of ultraviolet light. Ultraviolet light can cause premature wear of materials such as
rubber, plastic and enamel.
•Pay attention to objects sticking out from the scooter. These can cause damage to your
surroundings or to the scooter itself.
•Keep the scooter away from open flames.
•Avoid extreme weather conditions or extremely wet conditions. Maintain and store the scooter
in a clean and dry state.

Adjustment options
Version 2015v1 11
2 Adjustment options
There are a number of adjustments which can be made to the Fortress Calypso in order to improve its seating and
driving comfort levels.
Some adjustments are permanent adjustments made by the dealer using tools.
Other adjustments can be made by the user without the use of tools.
Adjustments can be made to the following by your dealer:
• Seat height
• Rear suspension
Adjustments can be made to the following by the user:
• Seat depth
• Backrest angle
• Armrest width
• Armrest height
• Headrest
• Steering column
2.1 Adjusting the seat
2.1.1 Adjusting the seat height
The entire seat can be adjusted in height in order to obtain the optimal seating position. This adjustment is carried
out by the dealer.
2.1.2 Adjusting the seat depth (sliding system)
(seat may vary from the illustration)
The seat depth can be adjusted as follows:
• Lift and hold handle (A).
• Slide the seat forwards or backwards.
• Release the handle once the seat is in the required position. Now slide the seat
slightly forwards or backwards so that it locks into place.
• The seat depth has now been adjusted.
2.1.3 Adjusting the backrest
The backrest angle can be adjusted as follows:
• Lift handle (A) whilst sitting on the seat.
The backrest now automatically moves forwards.
• Push the backrest to the rear by leaning against it until it is in the position
you find the most comfortable.
• Once adjusted, release the handle. The backrest remains in the position
you selected.
Caution: Exercise caution when using the handle when no
one is sitting on the seat. The backrest is equipped with a
spring mechanism which causes it to be driven quickly
forwards with some force.
The backrest can be adjusted to provide good back support while driving.
If the backrest is adjusted to an angle too far to the rear, the driver’s seating position is then less
stable, particularly on slopes.
It is therefore important never to drive your scooter if the backrest is inclined too far back.

Adjustment options
12 Version 2015v1
2.1.4 Adjusting the armrest
The armrests can be adjusted as follows:
• Rotary knobs (A) for adjusting the distance between the armrests are located at the
back of the seat.
• Turn the knob in an anti-clockwise direction to loosen the armrest.
• Once you have adjusted the distance between the armrests, tighten the rotary knobs
by turning in a clockwise direction. Then check to see whether the armrests are firmly
in place.
• The rotary knobs (B) for adjusting the height of the armrests are located on the rods
supporting the armrests.
• Turn the knob in an anti-clockwise direction to loosen the armrest.
• Press the nipple and slide the armrest upwards or downwards into one of the three
positions.
• Once you have adjusted the height, tighten the rotary knobs by turning in a clockwise direction. Then check to see
whether the armrests are firmly in place.
2.1.5 Adjusting the headrest
The headrest can be adjusted to various heights.
The headrest height is adjusted as follows:
• Press the plastic button at the point where the headrest is attached to the seat, at the same time moving the
headrest to the required height. The headrest can also be removed if required.
• Release the button and move the headrest slightly so that it locks into one of the positions.
2.2 Adjusting the steering column
The steering column can be adjusted to make driving more comfortable
and to make it easier for you to mount and dismount from the scooter.
The steering column is adjusted as follows:
• Using one hand, pull handle (A) downwards while pulling the steering
column towards you with the other hand until it is in the most comfortable
position.
• Release the handle. Then release the steering column.
If you release the steering column while still pulling the handle down, the
pneumatic spring will cause the steering column to jump into the most
forward position automatically.
Exercise caution while adjusting the steering column and
ensure that your fingers do not become trapped.
2.3 Adjusting the rear suspension
The rear suspension of the scooter can be adjusted to provide optimal comfort. This adjustment is carried out by
the dealer.
