Notice: These devices must be wired in accordance with Class I, Div. 2 wiring methods
as described in the National Electric Code, Article 501-4(b) or the authority having
jurisdiction. Transmitter unit is to be used with a purely resistive antenna when installed in
Class I, Div. 2 areas.
NSPING
1
The RAD-ISM-900-SET-UD-ANT is a Frequency Hopping Spread Spectrum radio
designed for the professional installation and integration with other products.
When installed with an approved antenna and cable, the system integrator needs
to make sure that the unit’s FCC label, or a copy of the FCC label, is clearly visible
on the outside of the integrated product. The RAD-ISM-900-SET-UD-ANT is
approved within the 902 to 928 MHz ISM Band under Part 15 of the FCC Rules
and Regulations.
Frequency Hopping Spread Spectrum technology was originally developed by
the U.S. military to prevent interference or interception of radio transmissions
on the battlefi eld. Frequency hopping devices concentrate their full power into
a very narrow signal and randomly hop from one frequency to another within a
designated frequency band. If they encounter interference on a particular frequency,
the devices error-check the affected data, hop to another point on the spectrum,
and resume communications on subsequent hops. Since there are always spaces
without interference somewhere in the allotted radio spectrum, a frequency
hopping device will use those spaces to complete a transmission.
WARNING: EXPLOSION HAZARD
Do not disconnect equipment unless power has been switched off or the
area is known to be non-hazardous.
FCC Rules and Compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
Changes or modifi cations not expressly approved by Phoenix Contact Inc. will void
the user’s authority to operate the equipment.
This product is intended for fi xed installation applications. In order to comply
with FCC/ISC-adopted RF exposure requirements, installation of this transmitter
system’s antenna must be performed in a manner that will provide at least a sixfoot (2m) clearance from the front radiating aperture to any user or member of
the public.

Note: Incorrect antenna placement and positioning can have a signifi cant impact
on the performance of the RAD-ISM-900-SET-UD-ANT. Keep the Omni antenna
vertical and mounted as high as possible. Extra cable may be required to achieve
Line-of-Sight (LOS) between the Transmitter and the Receiver.
For applications that require the antenna to be mounted away from the Transmitter,
please contact your distributor for cable and antenna options. Always follow the
mounting instructions and proper grounding procedures as outlined in the antenna
manuals.
