1.5 Warranty
The warranty follow EU standard which gives a total period of 2 years from invoice date. Furthermore it´s only valid if
the unit is used according to this user manual and no visible sign of unintended use..
Ihandle is intended to be used by cognizant persons over the age of 8. The Ihandle is not intended to be used by persons
who lack the finger mobility to eject the handpiece using their fingers. Use of the Ihandle that falls outside the intended
use described above is not covered by the warranty.
2Setting up Ihandle
2.1 System overview
The Ihandle consists of four parts: An activation unit (AU), a Handpiece Unit (HPU), a Control Unit (CU). The CU and HPU
each include a power supply. See Figure 1 for a diagram of the Ihandle, including the activation unit.
Figure 1 : Ihandle parts and cables.
The activation unit (AU) activates the sensors in the HPU and is placed either on a staff similar to the tongue piercing
used in the Itongue [ref] or is enclosed within a high density polyethylene (HDPE) staff. The AU staff is then inserted
through a hole created in a biocompatible fastening material. The staff is supplied with a flat, disc-like bottom to avoid
slipping of the AU through the hole. The fastening material is then tied around the finger of the user at a position that is
comfortable and easy to access HPU.

5 | P a g e
The Hand Piece Unit (HPU) is ideally placed around the finger of your hand when you are using Ihandle. The handpiece
can also be tied anywhere close to the hand or onto the machinery that is to be controlled. It is important that the HPU
is placed at a position comfortable for the user. The HPU is tied using a biocompatible fastening material. The HPU is
fixed on to the fastening material using a male screw that is passed through the hole created in the fastening material
and is bolted and tightened to the female screw present on the back side of the HPU. HPU is removed when Ihandle is
not in use.
The Control Unit (CU) allows you to operate a computer interface or control a wheelchair. The control unit has a touch
screen that can be used to adjust settings and change modes without using the handpiece. The control unit has a power
supply connector, as well as a connector for cabled connection to a wheelchair. The CU power supply is used when the
CU is in use with a computer or tablet. When the CU is connected to a wheelchair, the wheelchair power adapter cable
is connected to the power supply connection on the CU.
The handpiece unit has a power supply connector for charging it after use.
WARNING: DO NOT USE THE IHANDLE WITH OTHER POWER ADAPTERS
THAN THOSE SUPPLIED WITH THE SYSTEM. IF YOU REQUIRE A REPLACEMENT POWER ADAPTER,
CONTACT YOUR SERVICE REPRESENTATIVE.
All necessary Ihandle drivers are installed at delivery.
2.2 Before using the Ihandle for the first time
The Ihandle should be fitted and configured by a healthcare professional. Do not use the Ihandle before the correct
location and fit has been determined in collaboration with a healthcare professional.
The Ihandle should only be used by persons who are able to remove the handpiece using the fingers. Do not use the
Ihandle if you are not able to do so.
2.3 Setting up Ihandle
The HPU and AU should be affixed to the user's hand, finger or wrist in such a way that the user can comfortably move
the AU over the entire HPU surface. The HPU can also be affixed to the user's wheelchair using the screw threads on the
bottom. See figure 2 showing a possible method to attach the HPU and AU onto the user.
Figure 2 : Ihandle parts and cables

3.8.2 Error messages in wheelchair mode.
When in wheelchair mode the Control Unit can display the following error messages in red coloured text:
-“No Wheelchair”: A connection from the Control Unit to the wheelchair is not established. Check if the cable is
connected to the wheelchair and the wheelchair is powered on.
-“HandPiece missing!”: No radio connection from the Control Unit to the Hand Piece Unit is established. The
HPU is not present, not working or outside radio range.

13 | P a g e
-“No Radio 1”: Radio connection from the application processor to the HPU is lost. Signal is weak, noisy or has
temporary been interrupted by another device transmitting on the same radio frequency.
-“No Radio 2”: Radio connection from the supervisor processor to the HPU is lost. Signal is weak, noisy or has
temporary been interrupted by another device transmitting on the same radio frequency.
-“Data missing”: Bad radio connection to the HPU.
-“Data error”: Safety stop; calculated Joystick XY-coordinates from the application processor and supervisor
processor does not match. Some of those messages are to be expected in situations having several “No Radio
1” and “No Radio 2” dropouts - that is quite normal. But if this message is persistent and dominates in
occurrence over other messages, a faulty hardware is most likely the problem.
-"Wheelchair ERROR": Due to an error in the wheelchair, the Control Unit is unable to establish a connection.
This error can arise when the Wheelchair cable is connected to the Control Unit. Try removing the cable and
replacing it in the Control Unit. If the error continues, contact your wheelchair vendor.

4Settings
The Configuration window on the control unit allows you to adjust the behaviour of the handpiece in keyboard and
mouse mode to suit your needs. Wheelchair settings cannot be changed through the Ihandle.
Save all changes: This button saves all your current settings.
Cancel all changes: This button cancels all changes you have made to your settings since they were last saved. This
allows you to return to your previous saved settings, if you are unhappy with setting changes you have made.
4.1 Keyboard settings
To change the settings for the Ihandle keyboard, go to the Settings window and then the Keyboard Settings window in
the control unit menu. All the settings are adjusted by tapping the slider on the control unit screen to increase or
decrease. If you are using the handpiece, the left and right arrow buttons can be used to increase or decrease the value.
The buttons change colour when they are active. The following keyboard settings can be adjusted:
Dwell time: The time a sensor has to be active for the character associated with the sensor to be written. When a
sensor is activated, the associated character will appear. If the sensor is deactivated before the dwell time has passed,
the character will disappear again without being written. Activating the sensor longer than the dwell time will result in
the character being written. The higher the dwell time, the longer you will have to hold the activation over a sensor to
write the character. TKS recommends a higher dwell time for beginners.
Repeat time: The time a character is displayed before the next character appears. When the repeat time is high, each
character is shown for a longer interval, giving you more time to decide whether it was the right one. TKS recommends a
higher repeat time for beginners.
Goto Mouse time: Required activation time of the mode sensor for a direct jump between keyboard and mouse mode.
Value should be less than mode time (system settings screen).
Caps/Num time: Required activation time of the caps/num sensor for shifting between lowercase char, uppercase char
and numbers.
For further information see video on http://www.tks-technology.dk/support
4.2 Mouse settings
To change the settings for the Ihandle mouse, go to Settings, then Mouse Settings in the control unit menu. The
following settings can be adjusted here:
Invert XY: Reverses left and right or up and down on the cursor area. Invert XY is only possible for mouse control.
Release time: This setting determines how quickly the system responds to the activation unit moving away from a
sensor. If this time is low, the system will quickly interpret a movement away from a sensor as that sensor no longer
being active. TKS recommends a higher sensor release time for beginners.
Sticky time: This setting determines the time the mouse button sensor must be activated to select an item for drag and
drop. TKS recommends a higher sticky time for beginners.
Mouse speed factor: The speed of the cursor on the screen. A higher value means a higher cursor speed. TKS
recommends a lower mouse speed factor for beginners.
