3-1-1 Installation Environment
Installation Location
It is assumed that this product is to be used indoors, or outdoors if there is
a roof.
Do not install the Antenna in the following locations.
• Place exposed to direct sunlight.
• The ambient temperature is not within a range between 10°C and
55°C or locations with radical temperature changes resulting in
condensation.
• The humidity is not within a range between 35% and 85%.
• There is corrosive gas, flammable gas, dust, salt, or metal powder.
• The Antenna will be subjected to direct vibration or shock.
• Oil, or chemical will be sprayed onto the Antenna.
• Vicinity of noise source.
Peripheral environment
1) Influence of peripheral electronic devices
Any peripheral electronic devices present may reduce communication
range. Ambient noise can cause the communications range of the Antenna
to drop.
Ambient noise can be reduced by taking the following countermeasures.
• Power Lines and High-tension Lines.
Do not wire the Antenna cable along with high–tension lines or power
lines. Keep the Antenna cable as far away as possible from them.
• Inverters, Motors, and Other Driving Mechanisms.
Be sure to ground the frames of driving mechanisms and keep them as
far away as possible from the Antenna.
• Switching Power Supplies.
Be sure to ground switching power supplies and keep them as far
away as possible from the Antenna.
2) Influence of peripheral metals
Large metal objects around the Antenna may reduce communication
distance; therefore, place such metal objects at least the following
distances away from the Antenna:
• Distance between back metal of Antenna and back surface of Antenna:
50cm or more.
• Distance between side metal of Antenna and side of Antenna: 30cm or
more.
Caution Before installation, perform sufficient tests following the above points.
