Recommended separation distances between portable and mobile RF communications
equipment and the Otoport
The Otoport is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the Otoport can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Otoport as recommended below, according
to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance
d
in metres (m) can be estimated using the equation applicable to the
frequency of the transmitter, where
P
is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
Notes:
1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
The Otoport can be optionally configured with Bluetooth functions. The frequency band for
reception and transmission of RF energy for this function is as follows:
Bluetooth – 2.4GHz to 2.4835GHz
The Bluetooth function of the Otoport may be interfered with by other equipment, even if that
equipment complies with CISPR emission requirements.
