1. Important Warning and General Safety Information
1.1 General
The following information is presented to the operator to ensure awareness of potential harmful RF
(radio frequency) exposure and general hazards. With regards to potential harmful RF
electromagnetic fields the text below is only a brief summary highlighting the possible risks and how
to minimize exposure. The summary is based on OET Bulletin 65 “Evaluating Compliance with FCC
Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields”.
1
The user should
carefully read and comprehend the following before operating the equipment and for additional in
depth information refer to OET Bulletin 65.
1. FCC has set guidelines
1
for evaluating exposure to RF emissions that the user must be aware of
when operating the M2TE microwave transmitter. The maximum power density allowed from
1.7-7.0GHz is 5mW/cm
2
for occupational/controlled exposure* and 1mW/cm
2
for general
population/uncontrolled exposure**. These are the limits for maximum permissible exposure
(MPE) as called out in the FCC guidelines (for the above mentioned frequencies).
2. Exposure is based upon the average time spent within the RF field with a given intensity (field
units in mW/cm
2
)
2
. Hence it may be controlled (or at least minimized) by observing the safe
distances and time exposed. Safe distances are calculated from equations predicting RF Fields.

3. The transmitter is a mobile device, is rated at 0.2W (+23dBm) RF power and is capable of harmful
radiation if safe operating practices are not observed.
*”Occupational/controlled exposure limits apply to situations in which persons are exposed as a consequence of
their employment and in which those persons who are exposed have been made fully aware of the potential for
exposure and can exercise control over their exposure. Occupational/controlled exposure limits also apply where
exposure is of a transient nature as a result of incidental passage through a location where exposure levels may
be above general population/uncontrolled limits (see below), as long as the exposed person has been made fully
aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by
some other appropriate means……..”
(2)
** “General population/uncontrolled exposure limits apply to situations in which the general public may be
exposed or in which persons who are exposed as a consequence of their employment may not be made fully
aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the
general public would always be considered under this category when exposure is not employment-related, for
example, in the case of a telecommunications tower that exposes persons in a nearby residential area.“

4. Antenna minimum safe operating distance is 20cm (8inches) when using a 2dB Omni
antenna. It is the responsibility of the qualified end-user of this intentional radiator to control the
save distances and exposure limits to bystanders.
