directional position or the location of the Trumpet.
b) In the frequency range from 150 kHz to 80 MHz, field strengths must be lower than 3 V/m.
Recommended separation distances between portable and mobile RF
communication appliances and the device
The Trumpet is designed for use in electromagnetic environments where radiated RF
interference phenomena are kept under control. The user of the Trumpet can help to
prevent electromagnetic interference by ensuring that a minimum recommended
distance is maintained between portable and mobile RF communication appliances
(transmitters) and the Trumpet device, as indicated in the table below, according to
the maximum power output from the appliances in question.

For transmitters with a nominal maximum power output not included in the table above, the
recommended separation distance d in metres (m) can be estimated from an equation
applicable to the transmitter frequency, where P is the nominal maximum power output from
the transmitter in watts (W) specified by the manufacturer.
Note 1: At 80 MHz and at 800 MHz, the separation distance for the higher frequency range is
applied.
Note 2: These indications may not be valid in all situations. Electromagnetic propagation is
affected by absorption and reflection on encountering structures, objects and persons.
RF RADIATION EXPOSURE STATEMENT
This product complies with FCC and ISED radiation exposure limits set
forth for an uncontrolled environment. The antenna should be installed and
operated with minimum distance of 20 cm between the radiator and your
body.
Cet appareil est conforme aux limites d'exposition aux rayonnements de
l’ISED pour un environnement non contrôlé. L'antenne doit être installé de
façon à garder une distance minimale de 20 centimètres entre la source de
rayonnements et votre corps.
