D.THERMAL ROLL-BACK

Your chair has a thermal roll back circuit. This protects the controller 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. When the
controller cools, the chair will return to normal speed.
E. FUSES
Your Quickie QM-710/715HD/720 has two inline fuses.
• In the unlikely event of a short circuit or other fault, all power to your chair will be shut off.
• Qualified service personnel are required to repair the fault and replace the battery harnesses.
F. VR2 JOYSTICK ASSEMBLY
The standard VR2 joystick controls the chair's performance. It consists of the following parts:
1. Speed Control or Drive Mode Selection Buttons (A and B)
To decrease the speed level depress button A. Or, when 1- 5 Drive modes are programmed,
depress button A to activate lower drive mode(s).
To increase speed level, depress button B. Or, when 1- 5 Drive modes are programmed,
depress button B to activate higher drive mode(s).
Speed level active is indicated on display (C) by a series of five lights. One light indicates slow-
est level currently active, while five lights indicates highest level currently active.
Drive Mode is indicated by a single light. The first light indicates 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 disconnected 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.
4. Horn (F)
5. Joystick (G)
The joystick controls the direction and speed of your chair. Turn the chair on and move the
joystick in the direction you want to go.
• Moving the joystick from the neutral (center) position disengages the motor brakes, allowing
the chair to move.
• The chair will move faster the more you move the joystick away from neutral.
NOTE– If your speed becomes hard to manage, release the Joystick and the chair will come to a complete stop.
• When you release the joystick it will return to neutral; the chair will slow to a stop and the
motor brakes will reengage.
• We recommend that you switch the chair off if you stop for any length of time. This will con-
serve battery power.
NOTE– Once the chair stops, switching the chair off will not affect the motor brakes.
6. Joystick Boot (H)
Make sure the boot is not torn or cracked (this could allow debris, water or moisture to
enter). If the boot is torn or cracked, replace it as soon as you can.
7. Tilt or Lift Control (SC only) (I)
This button once depressed allows you to control the up and down movement of the tilt/lift. Press
button "I". Then push the joystick forward to tilt/lift the seat upward or pull the joystick back to
tilt/lift the seat downward. Pressing button "I" again will allow drive operations to resume.
