Installation
[GPS Antenna Installation]
○ Selecting the GPS antenna installation location
Install outdoors in a location that has an unobstructed line of sight to the sky.
When installing indoors, install near to a window that has an unobstructed line of sight
to the sky.
Caution
Do not install indoors in a location that does not have a line of sight
to the sky.
Doing so may cause unstable reception or the reception may be
affected by ambient noise, resulting in malfunction.
○ Locations unsuitable for reception
- Locations that do not have a clear line of sight to the sky, irrespective of whether
they are inside or outside
- Locations that have an object that reflects or intercepts radio waves near the
installation location
- Near wired window glass, window glass with smoke film attached, metallic slide
shutters or window blinds
- Locations that have a radio transmitting antenna or lightening conductor nearby
- Locations that have high-voltage wires nearby
- Locations that may become submerged in bad weather conditions
- Locations where the antenna may become covered in snow in winter
- Other locations that may be sheltered from or may have obstructions to radio
waves from GPS satellites
○ GPS Antenna Installation Orientation
Install the GPS antenna facing towards the zenith
(highest point in the sky)
(cables pointing downwards).
Installing with the case facing sideways or downwards
adversely affects the reception performance of the
antenna.
