3. Long-Range Transceivers:
These include commercial radio and TV broadcast antenna towers and
amateur (HAM) radios.
NOTE -
The following are not likely to cause EMI problems: Lap-top
computers (without phone or fax), Cordless phones, TV sets or AM/FM
radios, CD or tape players.
D. DISTANCE FROM THE SOURCE
Electro-magnetic energy rapidly becomes more intense as you get closer
to the source. For this reason, EMI from hand-held devices is of special
concern. A person using one of these devices can bring high levels of EM
energy very close to your chair without you knowing it.
E. IMMUNITY LEVEL
1. The level of EM is measured in volts per meter (V/m). Every power
assist device can resist EMI up to a certain level. This is called its

"immunity level".

2. The higher the immunity level, the less the risk of EMI. It is believed
that a 20 V/m immunity level will protect the power assist user
from the more common sources of radio waves.
3. The common configuration tested and found to be immune to at
least 20 V/m is: Quickie Xtender mounted to a Quickie 2
wheelchair using nickel hydride batteries.
A. WEIGHT LIMITS
NEVER exceed the weight limit specified by Sunrise Medical. The weight
capacity provided by your manufacturer is for the combined weight of a rider
and items carried using on-board storage. If you do exceed the weight limit,
damage to your chair, a fall, tip-over or loss of control may occur and cause
severe injury to the rider or others.
The maximum weight capacity for the Xtender is 265 lbs (120 kg).
If the maximum weight limit for your chair is lower than 265 lbs (120 kg),
do not exceed the stated weight limit for your chair.
B. INTENDED USE
The wheelchairs on which the Xtender has been installed, empower physically
challenged persons by providing a means of enhanced mobility. This owner's
manual refers to the power-assist accessory only. For warnings and
information about the correct use and care of your specific wheelchair,
please refer to the owner's manual provided with that specific chair.
DO NOT use this device for purposes other than what is intended by the
manufacturer. Unauthorized modifications and use of parts or
accessories not supplied or approved by Sunrise Medical may change the
chair structure. This will void the warranty and may cause a safety
hazard. If the warning is ignored, damage to your chair, and the potential
for severe injury of the person using the chair for unintended purposes
can occur.

WARNING
If there is any doubt that the specialty control input device is not immune
to 20V/m, extra care should be taken around known sources of EMI.
There is no way to know the effect on EMI if you add accessories or
modify this chair. Any change to your chair may increase the risk of EMI.
Parts not specifically tested or parts from other suppliers have unknown
EMI properties.
F. REPORT ALL SUSPECTED EMI INCIDENTS
You should promptly report any unintended movement or brake release.
Be sure to indicate whether there was a radio wave source near your chair
at the time. Contact:
Sunrise Medical, Customer Service Department at (800) 333-4000
G. EMI FROM CHAIR
The chair itself can disturb the performance of electromagnetic fields such
as emitted by alarm systems of shops.
C. ATTENDANTS AND CAREGIVERS
Before you assist a rider, be sure to read all warnings contained in this
manual, and follow all instructions that apply. Be aware that after
consulting a healthcare professional, you will need to learn safe and proven
body mechanics to use and create assistive methods best suited to your
abilities.
D. ACCESSORIES
Unauthorized modifications or use of parts, or accessories not supplied or
approved by Sunrise Medical may change the chair structure. This will void
the warranty and may cause a safety hazard.
Some problems that may occur, but are not limited to:
1. Incorrect wheels and/or tires that put the rider at risk of a fall
or tip-over.
2. Any modification or disassembly can potentially create an unsafe
situation where rider and/or attendant are put at risk.
E. KNOW YOUR DEVICE
Take the time to learn the feel of this device before you begin riding. Start
slowly, with easy, smooth strokes. If you are used to a different chair, you
may use too much force and tip over. If you use too much force, damage
to your chair, a fall, tip-over or loss of control may occur and cause severe
injury to the rider or others.
