K-MAR-5200 Instructions for Use
Recommended separation distance between portable and mobile RF communications equipment and the Vacuum Pump
The Vacuum Pump is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the Vacuum Pump can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Vacuum Pump 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.
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

Note: if necessary to achieve the IMMUNITY test level, the distance between the transiting antenna and the ME equipment or ME system may be reduced to
1m. The 1m test distance is permitted by IEC 61000-4-3.
a For some services, only the uplink frequencies are included.
b The carrier shall be modulated using a 50% duty cycle square wave signal.
c As an alternative to FM modulation, 50% pulse modulation at 18Hz may be used because while it does not represent actual modulation, it would be worst case.
