NOTE Canadian installations are required to meet Industry Canada specifications for maximum radiation as documented in Radio Specifications Standard 102 (RSS-102). For more information about RF exposure and related Canadian regulatory compliance, contact: Manager, Radio Equipment Standards Industry Canada 365 Laurier Avenue Ottawa, Ontario K1A 0C8 In accordance with Canadian Radio Specifications Standard 102 (RSS 102), an RF safety separation distance of 26 cm from the antenna should be maintained for an RF field strength exposure to persons of less than the 10W/m2 occupational safety limit. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. 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 necessary for successful communication. The GTR 200 has been approved by Industry Canada to operate with the antenna types listed below. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

Placement of the GPS antenna relative to a COM transceiver and COM antenna (including the GTR/ COM antenna), ELT antenna, and DF receiver antenna is critical. Use the following guidelines, in addition to others in this document, when locating the GTR 200 and its antenna. • Locate the GTR 200 as far as possible from all GPS antennas. • Locate the COM antenna as far as possible from all GPS antennas. If a COM is found to be radiating, the following can be done: • Replace or clean VHF COM rack connector to ensure good coax ground. • Place a grounding brace between the GTR 200 and ground. • Shield the GTR 200 wiring harness. 190-01553-00 Rev.

NOTE
Canadian installations are required to meet Industry Canada specifications for maximum
radiation as documented in Radio Specifications Standard 102 (RSS-102).
For more
information about RF exposure and related Canadian regulatory compliance, contact:
Manager, Radio Equipment Standards
Industry Canada
365 Laurier Avenue
Ottawa, Ontario
K1A 0C8
In accordance with Canadian Radio Specifications Standard 102 (RSS 102), an RF safety
separation distance of 26 cm from the antenna should be maintained for an RF field
strength exposure to persons of less than the 10W/m
2
occupational safety limit.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada.
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 necessary for successful communication.
The GTR 200 has been approved by Industry Canada to operate with the antenna types
listed below.
Antenna types not included in this list, having a gain greater than the
maximum gain indicated for that type, are strictly prohibited for use with this device.
A COM Antenna that meets TSO-C37( ) and C38( ) or TSO-C169( ), 50W, vertically
polarized.
Maximum gain of 1 dBi with an impedance of 50 ohms.
2.5.2
Interference of GPS
On some installations, VHF COM transceivers, Emergency Locator Transmitter (ELT) antennas, and
Direction Finder (DF) receiver antennas can re-radiate to the GPS antenna.
Placement of the GPS antenna
relative to a COM transceiver and COM antenna (including the GTR/ COM antenna), ELT antenna, and
DF receiver antenna is critical.
Use the following guidelines, in addition to others in this document, when locating the GTR 200 and its
antenna.
•
Locate the GTR 200 as far as possible from all GPS antennas.
•
Locate the COM antenna as far as possible from all GPS antennas.
If a COM is found to be radiating, the following can be done:
•
Replace or clean VHF COM rack connector to ensure good coax ground.
•
Place a grounding brace between the GTR 200 and ground.
•
Shield the GTR 200 wiring harness.
