Recommended Separation Distance between Portable and Mobile RF
Communications Equipment and the VS-2000
The VS-2000 is intended for use in electromagnetic environments where radiated RF interference is controlled. The
customer or the user of the VS-2000 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the VS-2000 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 meters (m)
can be determined 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.

Interference generated by electrical scalpels
When used with an electrical scalpel having the specifications described below, this device is protected against any
malfunctions that the resulting interference could produce.

Note 1
At 80MHz and 800MHz, 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.

Incision mode Output power 300W Output power 300W When an electrical scalpel generates high-frequency
energy the waveform noise level that is indicated and
recorded by the instrument increases. However, it
returns to normal levels less in 10 seconds or less
after the high frequency energy ends.
Usable analysis results may not be obtainable for
analyses made of waveforms during periods when
high-frequency energy is generated.
