Comfort and Ergonomics
The shape of the joystick is ideal for resting in the palm of your hand. It oers a
unique mechanical and tactile conguration that will amplify minimal force and
provides an option for good hand control.
Safe Driving
It is mandatory to have a wheelchair power on/o switch, which immediately shuts
down the wheelchair power and electronics, and is within easy reach of the user
while driving. This allows the wheelchair to instantly stop in case of problems or
an emergency.
WARNING The on/o switch must be available to the user at all times.
WARNING
In case the wheelchair responds in an unexpected way,
the user must immediately release the joystick
or use the power switch.

6
Installation
CAUTION Do not position the joystick where the hand may be
obstructed from moving in any direction.
WARNING
An incorrect programming of the
wheelchair electronics may cause damage
to the devices or injury to the user.
Joystick Operation
The Mushroom Joystick gives the user the ability to operate their wheelchair drive
parameters with smooth and precise control.
Prior to Operation
Ensure the wheelchair and Mushroom Joystick are correctly set up and adjusted to
the user's needs.
If the Mushroom Joystick does not perform as specied, turn o the wheelchair
and repeat setup or contact your supplier or Stealth Products.
Joystick Setup
It is important to properly install the Mushroom Joystick for the user. Take care
during the assessment to identify joystick placement, allowing maximum user
access and control.

NOTICE
If using Q-Logic™ Specialty Control Input Module (SCIM),
you will need any type of mechanical switch to plug into the
power port of the standalone joystick to power ON/OFF
the chair and ensure the SCIM as master control.
Q-Logic™ Programmer required.
NOTICE
For new chairs that have never been programmed, a power
cycle will need to be done after the joystick has been
calibrated and before the joystick throw can be adjusted.
WARNING
Manually disengage drive motors.
Prior to setting up the power chair's electronics to
recognize the input, ensure that the chair's power
is o and the motors are manually disengaged.
This will prevent unintentional chair movement.

Center Deadband
The Center Deadband parameter denes how far the joystick must be deected
from the neutral position to become responsive and start moving the power chair.
The value corresponds to the diameter of a circle around the joystick center
position. No drive or menu instruction will be executed unless the joystick is
moved out of this circle.

Assign Direction Function
The Assign Direction Function allows you to set the axis direction. For example, if
you want to change Forward (X axis 0 to 100) to Reverse (X axis 0 to -100) or Left (Y
axis 0 to -100) to Right (Y axis 0 to 100). If you switch Forward to Reverse, the
system will automatically change Reverse to Forward. Same with Left and Right.
Parameters are measured in percent (%).

Switch Operations
The Switch Operations parameter sets the joystick to operate like a switch input,
removing its proportionality. When the joystick is moved out of neutral and more
than 50% of the operating range, it will activate at full throttle (100%) in the desired
direction. Switch Operations can be set ON or OFF.

Joystick Throw
Throw is the location of maximum deection of a joystick in a particular direction.
It can vary by user based on capability. The throw should be based on the ability
of the user and set to the maximum deection the user is capable of producing.
