OtoRead™ Instructions for Use - US
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
TM
The OtoRead
is intended for use in the electromagnetic environment specified below. The
customer or the user of the OtoRead
Immunity Test
IEC 60601 Test
Level
Conducted RF
3 Vrms 150 kHz to
IEC 61000-4-6
80 MHz
Radiated RF
3 V/m 80 MHz to 2.5
IEC 61000-4-3
GHz
At 80 MHz and 8000 MHz, the higher frequency range applies.
These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
(a*) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the OtoRead
TM
OtoRead
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the OtoRead
(b*) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
TM
should ensure that it is used in such an environment.

Electromagnetic Environment-
Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of the
OtoRead
TM
, including cables, than
the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.17√����
d = 1.17√���� 80 MHz to 800 MHz
d = 1.17√���� 800 MHz to 2.5 GHz
where P is the maximum output
power rating of the transmitter in
watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in
meters (m).
Field Strengthens from fixed RF
transmitters, as determined by an
electromagnetic site survey (a*),
should be less than the compliance
level in each frequency range (b*).
Interference may occur in the vicinity
of equipment marked:
