freewheel mode while seated on it or standing next to it.
Do not attempt to have your power chair proceed backwards down any
step, curb, or other obstacle.
Excessively high cornering speeds can create the possibility of tipping.
Factors which affect the possibility of tipping include, but are not limited
to, cornering speed, steering angle how sharply you are turning ,
uneven road surfaces, inclined road surfaces, riding from an area of low
traction to an area of high traction such as passing from a grassy area
to a paved area especially at high speed while turning , and abrupt
directional changes. High cornering speeds are not recommended. If
you feel that you may tip over while cornering, reduce your speed and
steering angle to prevent your power chair from tipping.

Cornering Information

When cornering sharply, reduce your speed. When using your power
chair at higher speeds, do not corner sharply. This greatly reduces the
possibility of a tip or fall. To avoid personal injury or property damage,
always exercise common sense when cornering.
Take wide swings with your power chair's front wheel around any tight
corners, and your power chair's rear wheels will follow a wide arc. Not
cut the corner short, and not bump into or get hung up on any railing
corners.
Your power chair is designed to provide optimum stability under normal
driving conditions dry, level surfaces composed of concrete, blacktop,
or asphalt. However, Comfort recognizes that there will be times when
you will encounter other surface types. For this reason, your power
chair is designed to perform admirably on packed soil, grass, and
gravel. Feel free to use your power chair safely on lawns and in park
areas.
Reduce your power chair's speed when driving on uneven terrain
and/or soft surfaces.
Avoid tall grass that can become tangled in the running gear.
Avoid loosely packed gravel and sand.
If you feel unsure about a driving surface, avoid that surface.
Comfort recommends that you do not operate your power chair in icy
or slippery conditions or on salted surface. Such use may result in an
accident, personal injury, or adversely affect the performance and
safety of your power chair.
Comfort recommends that you do not expose your power chair to any
type of moisture at any time rain, snow, mist, or wash . Such expose
can damage your power chair. Never operate your power chair if it has
been expose to moisture until it has dried thoroughly.
Do not attempt to move an occupied power chair between floors using
a stairway. If moving a power chair between floors by means of a
stairway, the occupant must be removed and transported
independently of the power chair.

To Lock the VSI Please follow the steps
We recommend that the first few times you operate your power chair,
you set speed to the slowest setting until you become familiar with your
new power chair.
VSI Controller

1.Press the on / off key and power on the VSI. The
maximum speed / profile indicator should ripple
left and right.
2.Push the joystick to the full forward position until
the VSI beep.
3.Push the joystick to the full rearward position until
the VSI beep.
4.Release the joystick. There should be a long beep.
5.The VSI is unlocked now.
To Unlock the VSI Please follow the steps
If the above procedure fails to either lock or unlock the VSI, contact your
Comfort Specialist.
You charge the power chair batteries through the 3-pin socket located
on the front of the VSI. Off-board charger current should not exceed 12
amps. Contact your Comfort Specialist for more information.
The VSI controller is equipped with a thermal circuit. The circuit
monitors the temperature of the controller, which roughly translates to
motor temperature. In the event that the VSI controller becomes
excessively hot above 140 F motor current amperage is reduced.
For every degree above 140 F, the motor current limit is reduced by
.55 Amps until the VSI controller reaches 158 F, at which time the current
output is reduced to zero. This reduces your power chair's "power,"
which could also reduce your power chair's speed, and allows the
electrical components and motors to cool down. When the temperature
returns to a safe level, your power chair resumes its normal operation.
