1. Safety Information, Conformity Statement, and User Warnings
a.
Safety
The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radiated
frequency (RF) electromagnetic energy emitted by FCC certified equipment. This GE Harris equipment meets
the general population/uncontrolled environmental limits for Maximum Permissible Exposure (MPE) found in
FCC Bulletin OET-65 and OET-65, Supplement C. Proper installation and operation of this system according to
the instructions found in this Service Bulletin will result in human exposure substantially below the FCC
recommended limits.
To assure safe operation:
• Do not operate the system when nearby persons are within 20 cm (8 in) of the antenna
• Do not operate the system in an explosive environment
• To avoid damaging system components, do not operate the system unless the antenna(s) are connected
b.
Manufacturer’s Federal Communication Commission Declaration of Conformity Statement
This device complies with Part 15 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.
c.
User Warning
This Part 15 radio device operates on a non-interference basis with other devices operating at this frequency.
Any changes or modifications to said product not expressly approved by GE Harris could void the user’s
authority to operate the equipment.
d.
Professional Installation
The FCC’s certification of this system is contingent upon the system being professionally installed in accordance
with the instructions contained within this Service Bulletin. GE Harris provides an installation kit that contains
special accessories that are necessary to assure compliance with FCC emission limits. It is the responsibility of
the installer to use these accessories and perform the installation in accordance with the instructions contained
herein. Any deviation from these instructions could void the user’s authority to operate the equipment.
