n-ABLER PRO TRACKBALL
Product Description
The n-ABLER Pro trackball is specifically
designed for computer users with limited
hand control, motor skill difficulties, poor
hand-eye-coordination, limited manual
dexterity, involuntary muscle spasms and
hand or wrist tremors.
The n-ABLER Pro trackball is a computer mouse
emulator but, with fingertip control requiring
only minimal hand movement, reduces wrist and
elbow fatigue. The symmetrical design allows
users to work with either hand without angling
the wrist, and the unit can also be configured
for ‘left-handed’ operation. A large, integrated,
hand/palm rest makes work posture more
relaxed, reducing strain and tension.
The n-ABLER Pro trackball is particularly
suitable for all age groups with motor skill
difficulties and for those whose work requires
long periods at the computer. The ‘Anti-Tremor’
facility is invaluable for anyone suffering with
tremors or involuntary muscle spasms and for
older people with movement impairment.

Installation
USB (Preferred connection method)
Having located an available USB socket, simply plug your n-ABLER into it. It doesn’t matter whether
the computer is on or off. The first time you install n-ABLER the operating system may take a few
seconds to build a driver. Your n-ABLER is available for use as soon as its LED lights. There are no
driver files to load onto the computer - the computer’s resident drivers are used to help simplify
installation.
PS/2
Make sure your computer is fully turned off and not just in standby. Insert the USB plug of n-ABLER
into the supplied PS/2 adaptor and then plug it into the PS/2 socket, ensuring that the socket in
question is for a mouse and not for a keyboard. This can usually be identified either because it is
green (as opposed to purple for keyboard sockets) or it may be identified with a mouse symbol.
When you switch on your computer your n-ABLER automatically configures itself to PS/2 mode.
There are no driver files to load onto the computer- the computer’s resident drivers are used to help
simplify installation.
