5. FCC and Industry Canada Radiation Hazard Warning
To comply with FCC RF exposure requirements of FCC Rules Section 1.1307
and Industry Canada RF exposure requirements, the antenna used for this
transmitter must be fixed-mounted on outdoor permanent structures with a
separation distance of at least 92 cm from all persons.
6. Canadian Radio Standards Specifications (RSS) Compliance
Statement
This device has been designed to operate with the antennas listed in Section
4. of this manual, and having a maximum gain of 5.8 dBi. Antennas not
included in this list or having a gain greater than 5.8 dBi are strictly prohibited
for use with this device. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the Equivalent Isotropically Radiated Power
(EIRP) is not more than that permitted for successful communication.

7. Installation Instruction
CAUTION
The user and Installer should be aware that changes or modifications to this
equipment not expressly approved by Telematics Wireless could void
warranty and the user’s authority to operate the equipment.
Professionally trained personnel should install the equipment.
ATTENTION
The digital circuit of this device has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates uses and
can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
