Power consumption when transmitting is affected by the range setting. A greater range
setting uses more power.
2
When it is transmitting, the radar should be located in a position on the vessel that is at
least this far from people. (IEC 60936-1, clause 3-27.1, specifies the maximum distances
from the antenna at which radio frequency (RF) levels can be expected.)
These minimum safe distances apply for a transmitting radar with a rotating antenna, and
are much larger when the antenna is not rotating. If rotation of the antenna is obstructed for
any reason, the transmitter will automatically turn off.

Installation Troubleshooting
Symptom
Possible Causes
The radar does not
turn on. The status
LED is not on.
• The power cable may not be connected correctly to the
device or to the battery. Check all connections.
• The inline fuse may have blown. Check the fuse and
replace it if necessary.
• The wire gauge used to extend the power cable may be
too small for the length of the extension. Check the
table provided in the Power Cable Extensions section
of these instructions to make sure the correct wire
gauge is used (
Power Cable Extensions
, page 3).
The radar is not
available on the
Garmin device or
on devices
connected to the
Garmin Marine
Network.
• The radar may not be powering on. Check the status
LED.
• The device software may not be up-to-date. Update the
software on the device or on the Garmin Marine
Network.
• The network cable may not be connected correctly to
the device or to the Garmin Marine Network. Check all
connections.
• If a field-installable network connector was used, it
may have been installed improperly. Check the
connector.
The status LED is located on the product label, and can help troubleshoot
installation problems.
