Garmin GMR Fantom Open Array Series Field Service Manual

GMR Fantom™ Open Array Series
Field Service Manual
The GMR Fantom Open Array series radar generates and transmits
non-ionizing radiation. The radar must be turned off before approaching
the scanner for service. Avoid looking directly at the scanner while it
is transmitting, as the eyes are the most sensitive part of the body to
electromagnetic radiation. Before performing any bench test procedure,
remove the antenna and install the antenna terminator provided in the
Garmin Radar Service Kit (T10-00114-00). Failure to install the antenna
terminator will expose the service technician to harmful electromagnetic
radiation that can result in personal injury or death.
The GMR Fantom Open Array series radar contains high voltages. The
scanner must be turned off before the covers are removed. While servicing the
unit, be aware high voltages are present and take the necessary precautions.
The high voltages in the scanner can take some time to decay. Failure to
adhere to this warning can result in personal injury or death.
DO NOT place the GMR Fantom Open Array series radar into a test mode for
display purposes. When the antenna is attached, there is a danger of
non-ionizing radiation. The test modes should only be used for troubleshooting
purposes with the antenna removed and the antenna terminator in place.
Repairing and performing maintenance on Garmin electronics is complex
work that can result in serious personal injury or product damage if not done
correctly.
Garmin is not responsible for, and does not warrant, the work that you or a
non-authorized repair provider perform on your product.
