F. REPORT ALL SUSPECTED EMI
INCIDENTS
WARNING
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.
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
WARNING
EM energy rapidly becomes more intense as you get closer to
the source. For this reason, EMI from hand-held devices is of
special concern. (See C.1 above) 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
WARNING
1. The level of EM energy is measured in volts per meter
(V/m). Every power wheelchair 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
wheelchair user from the more common sources of radio
waves.
3. The Quickie Pulse with the following configuration was test-
ed and found to be immune to at least 20 V/m:
Quickie Pulse power wheelchair with a right-hand mounted
RNET controller, A.S.A.P. seat, flip-back armrests, solid flip-up
footplate and Group 22 batteries.
4. The following specialty input devices have an unknown effect on
the immunity level because they have not been tested with the
Quickie Pulse and RNET control system:
WARNING
Individuals with physical limitations requiring the use of a spe-
cialty control input device known not to be immune to
20V/m, or not known, should exercise extra care around
known sources of EMI.
WARNING
There is no way to know the effect on EMI if you add acces-
sories or modify this chair. Any change to your chair may
increase the risk of EMI. Parts from other suppliers have
unknown EMI properties.
