OPTIMAX TRACKBALL
Product Description
OPTIMAX is the very first, wireless trackball
specifically designed for users with motor skill
difficulties.
With an operating range in excess of 10 metres
OPTIMAX is ideally suited for use in team/group
sessions, or classroom settings, to ensure the
participation of all.
Lightweight and robustly constructed with no
mechanical wearing parts, OPTIMAX can be used
as either a desktop or hand-held unit.
Optical technology ensures precise cursor
control and silky-smooth ball movement, and the
bi-directional radio link provides interference
free operation.
OPTIMAX benefits from a built-in lithium ion
battery and advanced charging system, making
single-use batteries a thing of the past and
reducing the total cost of ownership. The unit is
charged from any USB socket using the supplied
cable and goes many months between charges.
INSTRUCTIONS

Compatibility
OPTIMAX works with USB compatible computers including PCs, Macs, Chromebooks, Apple phones/
tablets (via an adapter cable) and some Android phones/tablets (also via an adapter cable). It can
also work in PS/2 sockets on legacy PCs using an adapter cable which is available from Pretorian
Technologies or any authorised reseller.

drivers required).
• Auto detecting PS2 and USB protocols.
• PC, Mac and Chromebook compatible, plus
iPad/Android using adapter cables.
Installation
Ensure your computer is fully turned-off and not
just in sleep mode.
Locate the relevant PS2 or USB socket on your
computer and plug-in your OPTIMAX Receiver unit
(if you are using the PS2 socket on your computer
you will need a USB/PS2 adaptor).
To optimise the range of the radio link, do not place
the Receiver unit behind your computer or close to
large metal bjects or sources of interference such
as wireless network hubs, cellular telephones etc.
1. Ensure the internal battery is charged by
plugging the unit into a USB socket via the
supplied charging cable. The LED on the
Trackball unit lights green during charging
and is extinguished once the battery is fully
charged.
2. Move the Trackball to check for cursor
movement and if observed, your OPTIMAX
is now ready for use. If there is no cursor
movement, Pair the Trackball to the Receiver
by referring to the Pairing section below.
Maintenance
Your OPTIMAX has no user serviceable parts. If repair is necessary the unit should be returned to
Pretorian Technologies or an authorised Distributor.
Because USB is a much more popular connection format, the PS/2 adapter is no longer supplied as
standard. If you require a PS/2 connection, they can be provided free of charge. Please request one from
your local distributor.
Pairing
Your OPTIMAX uses a unique addressing system to ensure that there is no interference from
neighbouring units. The Trackball transmits its data along with an address, and the Receiver unit only
responds to that address.
To function correctly, both the Trackball and Receiver unit must use the same address. The process of
negotiating an address is called ‘Pairing’ and once learned, both the Trackball and Receiver units will
retain the information even when powered off or when changing the battery.

Your OPTIMAX is supplied already paired but it may occasionally be necessary to go through the process
again- for instance if a new Receiver is to be used with an existing Trackball unit or in the unlikely event
that one half ‘forgets’ the address.
To Pair the units, use the following procedure:
1. Remove the cover on the underside of the unit with a screwdriver.
2. Place the Trackball within one metre (three feet) of the Receiver unit.
3. Press the button on the underside of the Receiver unit.
The LED should flash.
4. Within 10 seconds, briefly press the button inside the battery
compartment. It is not necessary to spin the ball.
5. After a short period the LED should light steadily for 5 seconds and cursor
operation should resume.
6. Replace the cover on the underside and secure in place with a screwdriver.
7. If the LED stops flashing after around 15 seconds and does not light
steadily, repeat the process from (3). If it is still not successful, please refer
to the Troubleshooting section.

Learn Mode
There are a number of settings to allow you to configure OPTIMAX Trackball to your exact
requirements. These are all programmed using Learn Mode and are stored in an internal memory
so they are automatically recalled each time you use the unit, even if you swap computers or if the
battery goes flat. To make changes to the settings, you must first go into Learn Mode. Press and hold
the middle button until a beep is heard. The unit is now in Learn Mode and is able to accept changes to
the settings, as follows:
Cursor Speed
To change the speed setting while in Learn Mode, press the middle button briefly. Each time you do so,
the unit emits a beep of rising tone. The higher the tone, the faster the cursor will move. The speed of
the cursor changes immediately, allowing you to experiment until the best setting is found. There are
8 speed settings in all and pressing the middle button once the highest speed has been reached makes
the unit begin again at the lowest speed.
Left-Handed Operation
The left and right buttons may be swapped around, which is particularly useful for left-landed users.
To change this setting, press the left button while in Learn Mode. One beep indicates the unit is set to
standard ‘right-handed’ mode, whereas two beeps indicate ‘left-handed’ operation.
Battery Charging
Your OPTIMAX is fitted with a state-of-the-art lithium ion battery and charger. The unit will operate for
many months with a single charge. When the battery charge is getting low, the LED on the Trackball unit
will flash red every few seconds. This is an indication that it’s time to charge the battery soon. Locate the
supplied charging cable and plug it into the charging port on the rear of the OPTIMAX Trackball and then
into a USB socket on a computer or charging plug. The LED lights green to show that charging has started
and will be extinguished once fully charged.
Charging a battery that is completely flat takes about four hours and you can continue using the OPTIMAX
Trackball throughout the charging period, even from completely flat. Once fully charged, you may unplug
the charging cable.
Should you mislay the charging cable, replacements can be purchased by asking your local electrical
retailer for a camera connection lead. It has a USB type A plug at one end and a mini-USB plug at the other.
Note that OPTIMAX Trackball plugs into a computer USB port for charging purposes only and no
functional connection is made between the two devices.

Double Click
Right-click may be substituted with Double-Click, which is useful for users who have difficulty in
double-clicking quickly enough for the computer to recognise. To change this setting, press the right
button briefly while in Learn Mode. One beep indicates the unit is set to standard ‘right-click’ mode,
whereas two beeps indicates ‘Double-Click’ operation.
All of the above settings may be changed as often as required while in Learn Mode, allowing you
to experiment with the settings until the best configuration is found. Once you are happy with the
settings, they may be stored in the unit’s memory by pressing and holding the middle button once
again, until three beeps are heard. Normal operation then resumes.
Note that if both left-handed operation and Double-Click are selected, the buttons will function as Double-
Click, Drag and Left Click, reading from left to right.
Also note that the function of the sockets for external switches reproduces the function of the internal
buttons, according to the above settings.
