INSTALLATION
1.1
Display Unit Installation
The Display Unit (GP-1871F or GP-1971F) can be mounted in one of two ways: desk-
top (bracket) or flush mount (in the console, etc.).
When selecting a mounting location, keep the following points in mind:
• Determine the suitability of the mounting location before permanently mounting the
unit. Bulkheads and roofs can affect the incoming/outgoing signals, depending on
the shape of the vessel, preventing communication with the radar sensor. Signals
are strongest to the fore/aft direction of the unit; weakest to either side of the unit.

The unit should be located within the following distances from the radar sensor, to
ensure a stable connection.
Vessels with no obstructions: approximately 5 m, or less.
Vessels with obstructions: approximately 2 m, or less. (Avoid locations where the
obstruction(s) are composed of metal, carbon-fiber, or similar materials.)
• There should be no interfering objects within the line-of-sight to the satellites. An ob-
ject within line-of-sight to satellites, for example, a mast, may block reception or pro-
long acquisition time. Select a location out of the radar and inmarsat beams. Those
beams will obstruct or prevent reception of the GPS satellite signal.
• Locate the unit away from areas subject to water splash and rain.
• The operating temperature range of this unit is -15°C to +55°C. Be sure the mount-
ing location satisfies this requirement.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field-generating equipment such as mo-
tors and generators.
• Select a location away from VHF/UHF antennae, to avoid interference caused by
harmonic waves.
• Referring to the outline drawings at the back of this manual, leave sufficient room
for service and maintenance.
