Inspection
Inspect the shipping cartons and/or wooden box immediately upon receipt for evidence of damage during
transport. If the shipping material is severely damaged or water stained, request that the carrier's agent be
present when opening the cartons and/or wooden box. Save all box packing material for future use.
After unpacking the system and opening the cartons, inspect it thoroughly for hidden damage and loose
components or fittings. If the contents are incomplete, if there is mechanical damage or defect, or if the
system does not work properly, notify your dealer.
WARNING:
To avoid electric shock, do not apply power to the LT-300 GNSS Receiver if there is any sign of
shipping damage to any part of the unit or the outer cover. Read the Safety Instructions at the
front of this manual before installing or operating the unit.
Mounting and installation considerations
For optimum system performance, some guidelines on where to install or mount the LT-300 GNSS Receiver
must be followed. It is recommended to mount the unit in a location, with as much free line of sight as
possible, while making sure that the support structure fulfills the requirements for pole or roof mount
installation:
·
Mount the unit horizontally
·
Mount the unit with unobstructed view to the sky. If the Roof Mount is used for below deck
installation, make sure that the unit is capable of receiving signals from the GNSS satellites
·
Mount the unit on a rigid structure with a minimum of exposure to vibration and shock
·
Mount the unit in an area with an ambient temperature between -40°C and +55°C (-40°F to +131°F)
·
Mount the unit at least 1 m. (3 ft.) away from radio transmitting antennas (VHF, UHF, MF-HF,
Inmarsat, Iridium, Transmitting VSAT, etc.)
·
Mount the unit with a minimum angle of 20 degrees towards a radar antenna (above or below).
·
The compass safe distance for standard and steering compasses is 0.3 m (1 ft). Observe this distance
to prevent interference to a magnetic compass.
IMPORTANT: The pinol screw used for fastening the pole mount shall not exceed 0.8 NM (0.6 lbf-ft).
