6 Vrms The device is intended for use in
the electromagnec environment
in which radiated RF disturbances
are controlled. The customer or
the user of the device can help
prevent electromagnec
interference by maintaining a
minimum distance between
portable and mobile RF
communicaons equipment
(transmiers) and the device as
recommended below, according
to the maximum output power of
the communicaons equipment.
