Summary

Tests
for
compliance
with
FCC
Regulations
Part
15,
Subpart
C,
and
Industry
Canada
RSS(210/GEN,
were
performed
on
Schrader
model/PN(s)
13227143.
This
device
is
subject
to
the
Rules
and
Regulations
as
a
Transmitter.


In
testing
completed
on
April
11,
2007,
the
device
tested
in
the
worst
case
met
the
allowed
FCC
specifications
for
radiated
emissions
by
4.2
dB
(see
p.
6).
Besides
harmonics,
there
were
no
other
significant
spurious
emissions
found;
emissions
from
digital
circuitry
were
negligible.
The
conducted
emission
tests
do
not
apply,
since
the
device
is
powered
from
a
3
VDC
battery.

3.2Variants There
is
only
a
single
variant
of
this
device.


Two
modules
were
provided
for
testing,
one
hard(wired
for
CW
transmission
and
the
other
in
normal
operating
mode.


3.3ModesofOperation The
DUT
periodically
transmits
tire
pressure
data.

The
device
is
also
capable
of
being
automatically
actuated
(via
LF
interrogation)
either
by
in(vehicle
LF
initiators
or
by
trained
personnel
during
servicing.

Per
FCC
correspondence,
service
modes
fall
under
FCC
part
