Note 1: At 80 MHz and 800 MHz the interval with the highest frequency is applied
Note 2: These guide lines may not be applicable in all situations. The electro-magnetic propagation is influenced by the
absorption and by reflection from buildings, objects and people.
a) The field intensity for fixed transmitters such as the base stations for radiotelephones (mobile and cordless) and terres-
trial mobile radio, amateur radio devices, radio AM and FM transmitters and TV transmitters can not be theoretically and
accurately foreseen. To establish an electro-magnetic environment generated by fixed RF transmitters, an electro-magnet-
ic study of the site should be considered. If the field intensity measured in the place where the device will be used surpass-
es the above mentioned applicable level of conformity, the normal functioning of the device should be monitored. If abnor-
mal performance arises, additional measures such as changing the device's direction or positioning may be necessary.
b) The field intensity on an interval frequency of 150 kHz to 80 MHz should be less than 3 V/m.
Recommended separation distance between portable and mobile radio-communication devices and the monitor
The TOBI SUCTION UNIT surgical aspirator is intended to operate in an electro-magnetic environment where RF irra-
diated interferences are under control. The client or operator of the TOBI SUCTION UNIT device can help prevent elec-
tro-magnetic interference by keeping a minimum distance between the portable and mobile RF communication devices
(transmitters) and the TOBI SUCTION UNIT device, as recommended below, in relation to the radio-communication
maximum output power.

For transmitters with a maximum nominal output power not shown above, the recommended separation distance in metres
(m) can be calculated using the equation applicable to the transmitter frequency, where P is the maximum nominal output
power of the transmitter in Watt (W) depending on the transmitter's manufacturer.
