A. PERFORMANCE CONTROL SETTINGS
NOTE–
BEFORE attempting to check and/or adjust settings on your joy-
stick, be sure to see your dealer or clinician and have them
make adjustments if needed.
1. It is vital to match control settings to your level of function
and ability.
2. Consult your health care professional and your supplier to
select the best control settings for you.
3. Check and adjust the settings every six to twelve months.
WARNING
Adjust the control settings immediately if you notice any change in
your ability to:
• Control the joystick.
• Avoid running into objects.
• Control settings can be adjusted by your dealer
B. THERMAL ROLLBACK
Your chair has a Thermal Roll Back Circuit. This protects the con-
troller from damage due to overheating. In extreme conditions
(such as repetitive hill climbing), the circuit will decrease the power
to your motors. This allows the chair to operate at a reduced
speed, without overheating the components. When the controller
cools, the chair will return to a normal speed.
C. JOYSTICK STATIONARY
Your chair has an available programming feature called “Joystick
Stationary” which can be set by your dealer. This feature senses
when the joystick is displaced from neutral, yet left in a steady posi-
tion for a predetermined period of time. The controller will auto-
matically turn off if the set time has been reached. This feature is
designed to protect the user, batteries and electronics if the joystick
is inadvertently displaced. There are two parameters that can be
adjusted:
1. Joystick Stationary Time:
This is the time the joystick has to remain within the station-
ary range before the unit will come to a stop. It can be pro-
grammed from 0 to 60 minutes in steps of one minute.
Select 0 to disable the function. Default setting is 0
(Disabled).
2. Joystick Stationary Range:
This determines the size of a region around the present joy-
stick position. If the joystick remains within this region for
the stationary time the controller will stop. The range can be
programmed from 1 to 50, in steps of 1. Default setting is 1.
WARNING
Before turning on or adjusting these parameters, carefully read and
understand the implications for use of these features, Joystick
Stationary Time and Joystick Stationary Range. When the “Joystick
Stationary Time” is reached within the “Joystick Stationary Range”,
the drive motors on the chair will shut off. As an example, this will
happen while driving in a straight line for extended periods of time
with no joystick movement. Once the drive motors turn off, the
user will need to turn the chair off and back on to drive.
D. VR2 JOYSTICK ASSEMBLY
The standard VR2 joystick controls the chair’s performance. It con-
sists of the following parts:
1. Speed Control or Drive Mode Selection Buttons (A, B and C)
a. To decrease the speed level depress button(A). Or, when 1-
5 Drive modes are programmed, depress button A to acti-
vate lower drive mode(s).
b. To increase speed level, depress button (B). Or, when 1- 5
Drive modes are programmed, depress button B to activate
higher drive mode(s).
c. Speed level active is indicated on display (C) by a series of
five lights. One light indicates slowest level currently active,
while five lights indicates highest level currently active.
d. Drive Mode is indicated by a single light. The first light indi-
cates Drive Mode 1; the second light indicates Mode 2, and
so on.
2. Battery Charge Indicator (D)
Displays the charge available in the battery and alerts the user
when the charge level is low.
•
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 discon-
nected and you have switched the control system off and on
again.
•
If the battery gauge shows red, yellow and green, the batteries
are charged (bars 1-10).
•
If the battery gauge shows just red and yellow, then you should
charge the batteries as soon as you can (bars 1-7).
•
If the battery gauge shows just red, then you should charge the
batteries immediately (bars 1-3).
3. On/Off Button (E)
Turning the chair on or off is accomplished by depressing button E.
