Operational Safety Notices
The radio equipment described in this guide uses radio frequency transmitters.
Although the power level is low, the concentrated energy from a directional antenna may pose a
health hazard. Do not allow people to come in close proximity to the front of the antenna when
the transmitter is operating. More information on RF exposure can be found online at the following
website:
www.fcc.gov/oet/info/documents/bulletins
This manual is intended to guide a professional installer to install, operate, and perform basic
system maintenance on the described radio. The RF safety distance is calculated based on the 5
watt RF output (+37dBm) at the antenna connector on the back of the SDM chassis. This in-
cludes internal Duplexer and cable loss of ~3dB.

Consult factory prior to operation.
Not all frequency models available. Consult factory for available models.
Antennas with gain greater than 16dBi have not been authorized for use with the EUT; and (b) installation
of the EUT into portable applications with respect to RF compliance will require SAR testing and Regu-
latory approval.
Installation & Servicing Precautions
The unit is provided for professional installation only, and utilizes a specialized antenna con-
nector to restrict the types of antenna connections that may be made. The integrator of this de-
