X. OPERATING INSTRUCTIONS
J. COLOR LCD SCREEN
This section covers those joystick modules that are fitted with a color LCD screen. The color
LCD screen is split into three areas of information. The Top Bar, the Base Bar and the Main
Screen Area.
1. Top Bar
Battery Indicator : Displays the charge available in the battery and can be used to
alert the user to the status of the battery.
Steady: Indicates that all is well.
Flashing Slowly: The control system is functioning correctly, but you should charge the
battery as soon as possible.
Stepping Up: The wheelchair batteries are being charged. You will not be able to drive
the wheelchair until the charger is disconnected and you have switched the control sys-
tem off and on again.
2. Base Bar
Current Profile: The currently selected profile is shown in numeric form.
3. Main Screen Area
Drive Screen
Profile Name : This is a text string that displays the name of the currently selected
profile.
Clock : This displays the current time in a numeric format.
Speed Display : This gives a proportional display of the wheelchair’s speed.
Maximum Speed Indicator : This displays the current maxiumum speed setting.
Digital Speed Display : This displays the actual speed of the wheelchair derived from
the motors.
Inhibit : If the speed of the wheelchair is being limited; for example, by a tilted seat,
then this orange symbol will be displayed.
Mode Screens
Actuator Mode : Displays the sections of the chair currently selected for movement,
the name given to the selection and a direction arrow showing what sort of movement
is available.
Speed Adjust : When Speed Adjust Mode is entered, the following screen shown in
Figure 11 will be displayed.
Message Window : The RNET displays warning icons and informational messages, in
a dedicated message window.
Restart : When the control system requires a reboot; for example, after a module re-
configuration, this symbol will be flashed.
Timer : This symbol is displayed when the control system is changing between differ-
ent states. An example would be entering into Programming Mode. The symbol is ani-
mated to show the sands falling.
Diagnostic Screen
When the control system safety circuits have operated and the control system has been prevent-
ed from moving the wheelchair, a diagnostics screen will be displayed. This indicates a system
trip, i.e. the RNET has detected a problem somewhere in the wheelchair’s electrical system.
