(1)Power Switch: Press the power button on joystick, both power indicator and speed indicator should be on simultaneously showing battery volume and speed status. The power wheelchair will fail to drive if you push the joystick before the power indicator flashes; return the joystick to the center position and then push

it to drive after power indicator flash stops.

(2)Speed Check: Check the speed indicator first: more grades means higher speed. Lower speed is highly recommended for indoor driving.

(3)Forwarding: Control the drive direction by the joystick. As the user's view, push joy stick away from user to move forward; the farther the faster.

(4)Reversing: Control the drive directions by the joystick. As the user's view, pull joy stick close to user to

move backward; the farther the faster. However, the maximum reversing speed is a half to the maximum forwarding speed.

(5)Turning: Control the drive directions by the joystick. As the user's view, push joy stick toward right hand side to turn right, and push joystick tow ard left han d side to turn left; the farther the faaster.

(6)Electromagnetic Brake: Let go of joystick back to center for stop/parking by Electromagnetic brake.

Warning: Controllers are all programmed for best performances in different circumstances by manufacturer before delivery. Be sure to contact your dealer or DRIVE ME DICAL technical center to request your unique need by re-programming if necessary. It is extremely dangerous to modify or re-program unofficially, it might cause mechanical or electronic errors and threaten the safety of the user.

(7) Climbing:

a. Do NOT drive on any slope over 12 degree; otherwise, the wheels might consequently get off ground even though there are anti-tippers on the power wheelchair.

b. Medium speed drive is recommended for best maneuverability, high speed makes the power wheelchair difficult to control and lo w speed will cause the danger of motors over heat and consequently automatic shut-down by power-currency-overload protection of controller's self-monitoring system.

c. Do NOT make U-turn or reversing when climbing.

(8) Descending:

a. Do NOT drive on any slope over 12 degree; otherwise it might cause a dangerous situation. b. Be sure to keep half-speeded when driving down hill.

c. Do NOT make U-turn or reversing w hen driving down hill. An attendant's help is required in case of reversing when down a hill.

d. Be sure to slow down and drive straight when going down a hill.

Warning: Be sure to practice on gentle/gradual slopes before driving onto steep ascent. Do N OT drive over curbs or stairs or obstacles over 3cm without curb climbers.

Driving on slopes over 12 degree is prohibited for safety reason.
