IMPULSE DRIVE - OPERATION MANUAL

Major Component Identification

The Impluse Drive System is controlled by a Dynamic Mobility Shark drive controller. This system com

prises of two modules: the power module which is located beneath the bed near the drive wheels, and

the joystick/controller which is mounted on the headboard of the bed. Become familiar with all controls

with the power button in the OFF position. A detailed explanation follows.

Joystick Operation

Controls for the Impulse Drive System are located on the Shark Joystick/Controller, which is

mounted on the headboard. While becoming familiar with all controls, keep the power button in

the OFF position.

1. On/Off

2. Increase/Decrease Speed

3. Battery Gauge

4. Joystick

5. Horn

6. Speedometer

7. Attendant Control LED

8. Service Indicator LED

Joystick Console

1. TURNING THE POWER ON

Press the Power button. All indicators will flash briefly. The

current state of battery charge will be displayed and the powerchair may be operated as normal.

Note: If the SHARK is turned on while the joystick is out of neutral, an OONAPU fault will be dis

played - refer to the SHARK Display Information Chart.. Release the joystick back to neutral and

the fault will disappear.

OONAPU (Out Of Neutral At Power Up) is a feature that prevents SHARK from driving if the joystick

is out of neutral when SHARK is turned on or an inhibit condition removed.

This feature prevents sudden and unexpected movements.

1.1 TURNING THE POWER OFF

Press the Power button. The LED's will turn off.

Note: Alternatively, SHARK may be placed into a Lock Mode

(See Locking Instructions). This may

be preferable to turning the Drive System off if leaving the Bed at a place where unauthorized

persons may attempt to use it.

2. ADJUSTING THE DRIVING SPEED

The user can adjust the top speed to suit their

preferences and environment. The currently selected top speed is shown on

the Speedometer and can be adjusted using the "Increase Speed" (Hare) and

"Decrease Speed" (Tortoise) buttons.
