Design and Function

Intended Use
The Multi Joystick:

• is a joystick module which can be connected directly to the wheelchair electronics to control the wheelchair functions.
• is a small proportional joystick, which requires significantly less power and movement compared to a normal joystick.
• can easily be controlled by any body part, including finger, chin, lip … thanks to its flexibility.
• is recommended for people with tetraplegia, neuromuscular diseases (ALS, MS…) and limited muscular force.

NOTICE
The joystick operates with high sensitivity. A good and controlled movement coordination and force control is required.

Features
mo-Vis’ Multi Joystick features:

• full proportionality with reduced throw (8mm – 0.31 in) and force (49.89gf – 0.11 lbf);
• built-in compact and discrete housing;
• two 1/8″ (3.5mm) jacks for switch inputs;
• the ability to be linked with one or two switches (on/off and mode switch), with any 1.8″ (3.5mm) jack;
• full adjustability to individual needs with well-designed electronics;
• easy configuration with the free mo-Vis Configurator Software for positioning of the joystick; and,
• full R-net compatibility.

Mounting
The Multi Joystick can be mounted at any location on the wheelchair. By attaching the Power Chin Boom to the chair, the Multi Joystick can be used as a chin joystick*.
The Multi Joystick is compatible with Stealth joystick mounts, including:

• the SM600-661M for the ARMS260 Series Mounts;
• The SM661M for the swing-away chin control attached to a head support pad;
• The GAT461 mount for the Gatlin 400, 405, and 406 series; and,
• The IDCH series of chin controls.
• Note: No tray option is currently available for the Multi Joystick

Parts and Accessories

Multi Joystick Package
The following is included in the Multi Joystick package:

Multi Joystick Accessories
For mounting and further personalization, the following accessories are available:

Multi Joystick Protective Covers
The connections of the Multi Joystick unit have protective covers to avoid the accumulation of dust or moisture during use.

When using the joystick, an LED on the Multi interface will indicate the unit is functioning properly.
The LED will flash if an error occurs.
Please refer to the Fault Logs section of this manual for a list of errors indicated by a blinking LED on the Multi Joystick.

NOTICE
Before inserting a connector into the joystick, remove the protective cover from the desired input port.
NOTICE
Not all items in the Multi Joystick will be used to mount the Joystick onto a Stealth product. All of these items are compatible with the mo-Vis Power Chin Boom.

Functioning

Joystick Operation
The movements of the joystick translate accordingly into the motion of the wheelchair or the navigation of its menu. The wheelchair is most commonly controlled by the  joystick in the following manner:

• Direction: The joystick is pushed in the direction the wheelchair is intended to move, and the wheelchair moves in that direction.
• Speed: The further the joystick is pushed in any direction from its default (center) position, the faster the wheelchair moves in that direction.
• Stop: When the joystick is released from being pushed in a direction, it returns to its default (center) position and the wheelchair comes to a stop.

WARNING| When the LED flashes to indicate an error and/or after every incident with the wheelchair or the mo-Vis device,
contact Stealth immediately to perform a function test.
---|---
WARNING| The Multi Joystick operates with high sensitivity, requiring sufficient movement coordination and control of force. When operating the joystick, take care to avoid erratic or unsteady movements.
WARNING| When operating the Multi Joystick, always follow the instructions provided by the wheelchair manufacturer regarding safely operating the chair on different surfaces and angles of ascent and descent.
WARNING| Users should not use the Multi Joystick as the only support for a hand or limb, as irregular movements may  disrupt controls.
CAUTION| Avoid hitting obstacles during driving.

Joystick Safety
Do not use the Multi Joystick if any of the following conditions apply:

• The joystick handle is damaged, cracked, or missing.
• The joystick does not return to its default (center) position independently.
• The joystick does not move to and from its default (center) position smoothly.
  In order to change the joystick tip, gently pull on the tip until it lifts off the joystick’s metal rod. Place the replacement tip on the metal rod until it sits firmly in place.

WARNING
Always power off the device when the user is no longer in the wheelchair to avoid unauthorized access or accidental movements.

SAFE OPERATION
It is mandatory to have an on/off switch on the wheelchair which immediately shuts down the chair power and its electronics. It must be within easy reach of the user while operating the wheelchair.
This allows the user to instantly stop the wheelchair in case of problems or an emergency.

WARNING
The on/off switch must be available to the user at all times while operating the wheelchair.
WARNING
Do not cover or block the device to avoid uncontrolled behavior of the device or wheelchair.
If the wheelchair responds in an unexpected way during use, the user should immediately release the joystick and/or use the power on/off switch.

Connection Options
The Multi Joystick can connect one or two switches to either the joystick or the interface. One connection is to power the on/off function and the other is to act as an input  or user switch for the wheelchair.
The interface has a cable with a 9-pin connector compatible with the wheelchair electronics. The joystick then controls the wheelchair and all of its functions, including  driving, positioning, menu navigation, etc. It is also capable of powering the wheelchair on or off, as well as issuing mode commands.

red jack = on/off (power)
yellow jack = mode (input)

Electromagnetic Compatibility
The electronics of a power wheelchair and its options can be affected by external electromagnetic fields (for example, from mobile telephones). Similarly, the electronics of  the wheelchair or options themselves can also emit electromagnetic fields that can affect the immediate surroundings (for example, certain alarm systems in businesses).
This product complies with the limit values for Electromagnetic Compatibility (EMC) with respect to power wheelchairs, as set out in the harmonised standards for the EU in the Medical Device Regulation, No. 2017/745.
