Table 1-4: Recommended separation distances between portable and mobile RF communications equipment and the ME
equipment or ME system – for ME equipment and ME systems that are not life-supporting
The XSlate R12 Rugged Tablet PC is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the XSlate R12 Rugged Tablet PC
can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the XSlate R12 Rugged Tablet PC as
recommended below, according to the maximum output power of the communications equipment.

Notes:
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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
Safety and hazards
Do not operate your EM7455 or EM7511 modules:
• In areas where blasting is in progress
• Where explosive atmospheres may be present including refueling points, fuel depots, and
chemical plants
• Near medical equipment, life support equipment, or any equipment which may be susceptible
to any form of radio interference. In such areas, the EM7455/EM7511 modules MUST BE
POWERED OFF. Otherwise, the EM7455/EM7511 modules can transmit signals that could
interfere with this equipment.
In an aircraft, the EM7455/EM7511 modules MUST BE POWERED OFF. Otherwise, the
EM7455/EM7511 modules can transmit signals that could interfere with various onboard systems and
may be dangerous to the operation of the aircraft or disrupt the cellular network. Use of a cellular
