Note
To operate, the DX2-RJM and DX2-RJM-LF must be connected to a DX system via the DXBUS trailing lead.
Warning
:
Do not use the compact remote module if it is worn or damaged. Worn or damaged modules should be serviced
immediately, especially if the DXBUS cable, joystick gaiter or keypad are ripped, torn or damaged.
7.1.1 The joystick
Warning
:
The compact remote modules may only be used with the authorised joystick knobs. Use of any other joystick knob
requires that the installer tests and confirms that the joystick returns to the neutral position whenever the joystick
is deflected. Tests with the device mounted horizontally and with a water soaked knob (foam knobs only) are
required if the installer judges these risks as significant.
Figure 19: The joystick
The joystick controls the direction and speed of the wheelchair.
When the joystick is deflected from the centre (neutral) position, the
wheelchair will move in the direction of the joystick movement.
The speed of the wheelchair is proportional to the joystick deflection, so that
the further the joystick is moved from the neutral position, the faster the
wheelchair will travel.
If the user moves the joystick back to the neutral position, the wheelchair will slow down and stop.
If the user releases the joystick from any position other than the neutral position, the joystick will
return to the neutral position and the wheelchair will slow down and stop.
The joystick can also be used to wake up the system when in sleep mode — see 7.1.8 Sleep mode .
Warning
:
It is the responsibility of the wheelchair manufacturer to inform the wheelchair user about the wheelchair's
stopping distances.
