GC2 CONTROLLER
The GC2controller is a fully-programmable, modular electronic controller system
that allows you to operate your power chair. It is designed to allow the user to have
complete control over chair movement and speed.
The controller has been pre-programmed to meet a typical user’s needs. The
program is set using either a personal computer with software provided by the
controller manufacturer or with a hand-held programmer, also provided by the
controller manufacturer.
WARNING! The controller program can affect speed,
acceleration, deceleration, dynamic stability, and braking.
If it is programmed incorrectly or outside of the safe limits
as determined by your healthcare professional, it can create
a dangerous situation. Only the power chair manufacturer,
an authorized representative of the manufacturer, or a trained
service technician should program the controller.
PRECAUTIONARY GUIDELINES
Before operating the GC2 controller, please read the following. These guidelines
are provided for your benefit and will aid you in the safe operation of the control
system.
ꢀ Turn off the power to the controller when transferring to or from your power
chair.
ꢀ Follow all of the procedures and heed the warnings as explained in your power
chair owner’s manual.

Basic Operation Instructions
Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that electromagnetic
and radio frequency waves can have an adverse affect on
the performance of electrically-powered mobility vehicles.
Electromagnetic and Radio Frequency Interference can come from sources such as
cellular phones, mobile two-way radios (such as walkie-talkies), radio stations, TV
stations, amateurradio(HAM)transmitters, wirelesscomputerlinks, microwavesig-
nals, pagingtransmitters, andmedium-rangemobiletransceiversusedbyemergency
vehicles. In some cases, these waves can cause unintended movement or damage to
thecontrolsystem. Everyelectrically-poweredmobilityvehiclehasanimmunity(or
resistance) to EMI. The higher the immunity level, the greater the protection against
EMI. This product has been tested and has passed at an immunity level of 20 V/m.
WARNING! Be aware that cell phones, two-way radios,
laptops, and other types of radio transmitters may cause
unintended movement of your electrically-powered mobility
vehicle due to EMI. Exercise caution when using any of these
items while operating your mobility vehicle and avoid coming
into close proximity of radio and TV stations.
WARNING! The addition of accessories or components to
the electrically-powered mobility vehicle can increase the
susceptibility of the vehicle to EMI. Do not modify your power
chair in any way not authorized by Pride.
WARNING! The electrically-powered mobility vehicle itself
can disturb the performance of other electrical devices
located nearby, such as alarm systems.
NOTE: For further information on EMI/RFI, go to the Resource Center on
your power chair off as soon as it is safe to do so. Call Pride or your autho-
rized Pride Provider to report the incident.

Speed Dial
The GC2 controller provides a speed dial to control the speed of the power chair.
See figure 3.
To change the speed:
1. Push the on/off key to power on the chair and the controller.
2. To increase your speed, turn the speed dial clockwise.
3. To decrease your speed, turn the speed dial counterclockwise.
NOTE: We recommend that the first few times you operate your power
chair, you set the speed to the slowest setting until you become familiar
with your new power chair.
Battery Condition Meter
The battery condition meter consists of five LEDs arranged in an arc over the on/off
and horn keys. See figure 1. When functioning as the battery condition meter, this
indicates the status of the electrical system using LED codes. For example, as the
batteryvoltagedrops, thenumberofLEDsreducesfromrighttoleft. Whenthebattery
capacity drops to 10% or below, the left red LED will flash.
Battery condition meter codes are as follows:
ꢀ Left Red LED Flashing Slowly or Steady: Battery charge is low; Charge
the batteries as soon as possible.
ꢀ Red andYellow LEDs Flashing: Battery charge is low; Charge the batteries
overnight.
ꢀ Step up of LEDs:The controller is in programming, inhibit, or charging mode.
ꢀ All LEDs Flashing Quickly: The joystick was not in the center position
when the power was switched on, or the controller system detected a fault;
Refer to the Fault CodeTable.

Basic Operation Instructions
LOCK MODE
The controller is equipped with a feature that enables you to “lockout” unautho-
rized users.
To lock the controller:
1. While the power is on, press and hold the on/off key until it beeps
(approximately 1 second).
2. Release the on/off key.
3. Move the joystick to the full forward position until it beeps.
4. Move the joystick to the full rearward position until it beeps.
5. Release the joystick. There will be one long beep. The controller system is
now locked.
NOTE: The battery condition meter will be rippling from side to side. The
sequence will continue until the power is turned off or until the control-
ler is unlocked.
To unlock the controller:
1. Press the on/off key to turn on the controller. The battery condition meter will
ripple the “locked” sequence.
2. Move the joystick to the full forward position until it beeps.
3. Move the joystick to the full rearward position until it beeps.
4. Release the joystick. There will be one long beep. The controller system is
now unlocked.
THERMAL ROLLBACK
The GC2 controller is equipped with a thermal rollback circuit which monitors the
temperature of the chair’s motors and controller. If either exceeds the safe operating
temperature, the controller reduces the output to 50% of full operation level. This
reduces the chair’s speed and allows a cool down period. Once the temperature
returns to a safe level, the chair will resume normal operation.

an abnormal condition in the electrical system. All of the battery condition meter
LEDs will flash a number of times quickly, then pause, then flash again.The battery
condition meter will continue to flash the fault codes until the problem is fixed. The
table below identifies the individual fault codes. If any of these fault codes persist,
contact your authorized Pride Provider.
