Use an Allen wrench to install the device.
CAUTION: Use proper tools to install and adjust the device. The use of improper tools may cause damage to the device.

Installation plan
Set up an installation plan before beginning the installation. Based on the users’ needs and capabilities, this plan should take into account:

• Where which part of the device should be placed.
• How the device will be operated.
• A robust and reliable positioning. Hard or sudden movements of the wheelchair may not disorganize the installation.

WARNING: Protect the device against bumps. Mind damaging the unit and wiring. Make sure that cabling is mounted in such a way that excessive wear and tear is avoided.
WARNING: Do not use the joystick as only support for hands or limbs. Movements and shocks may disrupt controls.

Installation

1. Define the position of the joystick.
   When the arrow at the bottom of the joystick points to the front, a forward movement of the joystick will result in an according forward movement of the wheelchair. If needed, you can change this positioning in steps of 90° with the Configurator Software.

2. Place the mounting ring around the joystick housing.

3. Secure the Q2M half clamp to the mounting ring. Use an Allen wrench to mount the 20 mm bolt.
   NOTE: It is not advised, but you may mount the joystick without using the Q2M half clamp.
   CAUTION: Tighten the screws firmly, but not excessively. Excessive force may damage the unit.

4. Slide the unit over a Q2M Rod, or any other 6 mm rod, to position the Micro Joystick on the wheelchair. A Q2M Rod D6 50 mm is included in your package, but you can use any other Q2M Rod (e.g. a C- or S-Rod from the Multi Swing).

5. Place and secure the interface unit and all cabling on the wheelchair.

6. Place a power on/off (pwr) and/or mode (in) switch, secure their cabling, and insert their connections. You can use the connections on the Interface unit.
   CAUTION: Before inserting a connector, remove the protective cover. If the connections are not used, always put or keep the protective covers in.
   CAUTION: This is Class I Medical Device (MDR 2017/745). All accessories, including switches, must also comply with the MDR 2017/745 regulations (e.g. the mo-vis Twister, tested according to EN12184 standards).

7. Connect the cabling to the wheelchair electronics.
   CAUTION: All wheelchair electronics must be switched off during installation.

Operation

The movements of the joystick are translated into according movements of the wheelchair, e.g. driving or menu navigation.
Common practice to navigate the wheelchair with the joystick is as follows:

• Direction: point the joystick into the direction you want the wheelchair to move. The wheelchair then moves in that direction.
• Speed: the further you move the joystick from the default (center) position, the faster the wheelchair moves.
• Stop: whenever you release the joystick, the joystick moves back to the default (center) position and the wheelchair stops.

CAUTION: Avoid hitting obstacles during driving.
WARNING: When the LED light flashes and/or after every incident with the wheelchair or the mo-vis device, contact your dealer immediately to perform a functional test.

Configuration

WARNING: Changes in parameter settings may cause damage to the device or power chair, or may cause injury to people.
CAUTION: Always change parameters and test the outcome without anyone sitting in the power chair?

The wheelchair will stop dri- ving when the parameter is set to ‘On’ and the joystick is tilted more than 70° in any direction (LED will flash orange).

The tilt sensor inhibit becomes inactive again when the angle becomes less than 60° (green LED is on, see Omni Joystick Con- nection on page 30 and

R-net Joystick Connection on page 37 ).

The use of this functional- ity certainly makes sense when a mo-vis joystick is integrated in a tray or other tilting surface/mounting aid.

NOTE: The tilt sensor response time is less than or equal to 1s.

Fault log
TROUBLE:
A fault log with counters is maintained. The fault log can be accessed by the configurator (dealer level). Below is an overview of registered faults.

R-net Joystick Connection

Purpose
An R-net joystick has a communication cable with an R-net connector. The cable can be directly plugged into the R-net electronics of the wheelchair. The joystick then controls the wheelchair in all its functions (driving, electric gears …).
For more information about the R-net system, please refer to the Curtiss- Wright website http://www.cw-industrialgroup.com
Connecting the R-net communication cable
To connect the communication cables, insert the connector into its mate and push firmly. The connector is inserted correctly if the yellow pins are completely invisible. The connectors are secured using a friction system.

To disconnect the communication cables, firmly hold the connector housing and pull the connectors apart.
NOTE: Pull the connector apart in a straight line to not damage the connection pins.

R-net parameters
Some R-net parameters need to be set for correct usage of the mo-vis R-net joysticks. For this we refer to the Curtiss-Wright manual SK77981-14 | R-net Technical Manual | Chapter 3 – Programming
R-net (Ch. 3 – 4.4): Profile Management > Input Device Type:

• In most cases, this parameter needs to be set to Universal for all mo-vis joysticks.
• In combination with certain other devices (e.g. Scoot Control), it is advised to set this parameter to JSM. Please refer to the Installation manual of the other devices for more information.

NOTE: If you have several input devices of the same type, please refer to the Curtiss-Wright manual SK77981-14 | R-net Technical Manual | Chapter 3 – Programming to install as Input Device Subtype. R-net (Ch. 3 – 7.5): Controls
