This manual is for the use of professionals to guide them in the installation, operation and
basic system maintenance of the equipment covered.
Caution:
OEM900MR complies with part 15 of the FCC Rules and IC Notice.
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
To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that permitted for successful communication.
Caution - Changes or modifications not expressly approved by the OMNEX Control
Systems ULC will void the user’s authority to operate the equipment.
The following antenna types may be used:
Model: Description:
RAD-ISM-900-ANTOMNI-0-6

RF Exposure Information
READ THIS INFORMATION BEFORE INSTALLING THE OEM900MR
This product is intended for fixed installation applications. In order to comply with
FCC/ISC adopted RF exposure requirements, installation of this transmitter system's
antennas must be performed in a manner that will provide at least 8 inches (20 cm)
clearance from the antenna to any user or member of the public.
OEM900MR was certified with the following antennas: RAD-ISM-900-ANT-OMNI-0-6
(¼ Wave Whip Antenna with 1.8 m (6 ft.) Cable) and YA6900W (4 Element, 8dBi, Yagi
with 20 ft. (6m) Cable).
The maximum radiated output power of these antennas satisfies the maximum
permissible exposure (MPE) limits as specified in §1.1310 of FCC regulations for general
population/uncontrolled exposure as long as the minimum separation distance of 20cm
between the radiating element and the person is maintained
