SAFETY
Your Compass HD™ is a battery-operated personal mobility vehicle. Please exercise
caution and consideration when you are operating it. Driving your Compass HD
carefully and thoughtfully will help ensure your personal safety and the safety of other
people.
NOTE: Before learning to operate your Compass HD, have your Golden
Technologies, Inc. representative determine if it is advisable for you to
practice getting on and off your Compass HD and operating it in the
presence of an attendant.
BEFORE GETTING ON YOUR Compass HD
♦Check to be certain that the power is turned off. See “Operation” on pages 22-27.
This will eliminate the possibility of accidentally activating the joystick and causing
injury to yourself or to others.
♦Check to be certain that your Compass HD is not in freewheel mode. See the
“Operation” section on pages 22-27.
♦Flip up the armrests.
♦If your chair is equipped with leg rests, move them to the sides.
♦If your chair is equipped with a footrest, flip it to the “up” position.
GETTING ON YOUR Compass HD
♦While being careful not to entangle yourself in the leg rests or the footrest, seat
yourself comfortably and securely on the seat.
♦Adjust the leg rests or flip down the footrest.
♦Flip down or replace the armrests.
♦Fasten the lap belt, if your chair is so equipped.
GETTING OFF YOUR Compass HD
♦Make certain that the power is turned off.
♦Unfasten the lap belt, if your chair is so equipped.
♦Flip up the armrests.
♦Flip up the footrest, or move the leg rests to the sides.
♦While being careful not to entangle yourself in the leg rests or the footrest,
carefully stand and step away from the chair.
MAXIMUM WEIGHT
Your Compass HD has been rated to a maximum payload (passenger and anything else
being carried on the Compass HD)of 450 pounds. Exceeding the maximum weight
rating will void the warranty.
Exceeding the maximum weight rating may result in injury to yourself and to others.
This will also void your warranty.

SAFETY
DRIVING ON AN INCLINE
♦Drive with caution when attempting to negotiate any incline, even handicap access
ramps.
♦Always climb or descend a gradient by driving straight up or straight down the face of
the slope.
♦Do not traverse or drive across the face of a gradient.
♦Do not attempt to negotiate an incline that is covered with snow, ice, cut or wet grass,
leaves, or any other potentially hazardous material.
♦Do not back down an incline.
♦Try to keep your Compass HD™moving when climbing an incline. If you do come to a
stop, restart and accelerate slowly and carefully.
♦Do not try to descend or climb an incline that is greater than the maximum incline
stated in the specifications section of this manual.
If, while you are driving down a slope, your chair starts to move faster
than you feel is safe, gently release the joystick and allow your
Compass HD™to come to a stop. When you feel that you again have
control of your power chair, adjust the speed control to a lower setting
then push the joystick forward and continue safely down the remainder
of the slope.
MEDICATION
Always check with your physician to determine if any of the medications you are taking
may affect your judgment and/or your ability to operate your Compass HD™.
Do not connect or allow anyone except an authorized Golden
Technologies, Inc. representative to connect any electrical or
mechanical device to your Compass HD™. Unauthorized accessories
will void the warranty and may cause injury.

♦Do not operate your Compass HD™ if it is not functioning properly.
♦Use caution when driving on soft or uneven surfaces such as grass, gravel, and on
decks where there is no railing.
♦Never drive on the roadway, except when you must cross the street.
♦Always cross streets at intersections and use the most direct route, making sure
that your path is clear and that you are visible to motor traffic.
♦Never drive your Compass HD™up or down a step or curb that is higher than 1 1/2
inches.
♦Never back up or down a step or curb.

EMI/RFI
The rapid development of electronics, especially in the area of communications, has
saturated our environment with electromagnetic (radio) waves that are emitted by
television transmitters, cellular phones, citizen’s band radios (CBs), amateur radios (ham
radios), wireless computer links, microwave transmitters, paging transmitters, etc.
These electromagnetic (EM) waves are invisible and increase in strength the closer one
gets to the source of transmission. When these energy waves act upon electrical devices
and cause them to malfunction or to function in an erratic or uncontrolled manner, they
are referred to as Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI).
EMI/RFI AND YOUR Compass HD™
All electrically powered vehicles, including power chairs are susceptible to EMI/RFI. This
interference could result in abnormal, unintended movement of a power wheelchair.
The FDA has determined that each make and model of power chair can resist EMI/RFI to
a certain level. The higher the level of immunity, the greater the degree of protection
from EMI/RFI measured in volts per meter (V/m). The FDA has also determined that
current technology is capable of providing 20 V/m of immunity to EMI/RFI, which would
provide useful protection against common sources of interference.
Based on that determination, the FDA has written to the manufacturers of power wheel-
chairs and asked them to test their new products to be certain that they provide a rea-
sonable degree of immunity to EMI/RFI. The FDA suggests that power chairs should
have an immunity level of 20 V/m.
The immunity level of the Compass HD™ is unknown.
EMI/RFI RECOMMENDATIONS
♦Do not turn on or use hand-held personal electronic communication devices such as
cellular phones, walkie-talkies, and CB radios while your power chair is turned on.
♦Be aware of any nearby transmitters (radio, television, microwave, etc.) on your in-
tended route and avoid operating your chair close to any of those transmitters.
♦Turn off the power if your Compass HD™is going to be in a stationary position for any
length of time.
♦Be aware that adding accessories or components or modifying your power chair may
make it more susceptible to EMI/RFI.
♦If unintended movement or brake release occurs, turn your power chair off as soon
as it is safe to do so.
♦Report all incidents of unintended movement or brake failure to your Golden repre-
sentative or to Golden Technologies, Inc. at [phone].
Turn off your power chair as soon as it is safely possible if
unintended or uncontrollable motion occurs or if unintended brake release
occurs.
