DAVIS Vantage Pro ISS, 2003 & later - Manual (Page 12)

Siting the ISS and Anemometer: General ISS Siting Guidelines:
10
• Range may be reduced by walls, ceilings, trees, foliage, a metal roof or other
large metal structure or objects such as aluminum siding, metal ducting, and metal
appliances such as a refrigerator.
• Radio-frequency interference (RFI) will also reduce transmission distance. Cord-
less phones (900 Mhz) and ham radios are common examples of RFI.
• Transmission between wireless units may be obscured by something you cannot
identify, or by some obstacle that you can’t work around.
• As a general rule, orient the ISS antenna and the console antenna so that they
are parallel with each other.
• The signal may be weak directly underneath the ISS. Try rotating the ISS and the
console antennas to parallel, horizontal positions if you are installing the ISS
directly over the console.
• Turn the gain on to improve reception for a weak signal. Refer to the Vantage Pro
Console Manual for information on setting the console gain.
• If necessary, consider using a Wireless Repeater #7624 or #7625, to strengthen
the signal or increase the distance between your ISS and the console. See
“Optional Wireless Stations” on page 16
Testing Wireless Transmission at ISS Location
Note: After you have found a suitable place for your wireless ISS, it is very important to test reception
from that location before permanently mounting it there.
1. Set the ISS where you intend to install it. You may want to have someone hold it in
place during the test.
2. Set console where you intend to use it.
Note: For example, let’s say you are installing a Wireless Vantage Pro with the ISS mounted on a
fence at the back of the property. With the ISS up on the fence temporarily, test the console’s
reception where you intend to use it.
3. On the console, press and hold the TEMP button and press the TIME button to dis-
play reception statistics.
• It’s a good idea to test the console’s reception anywhere that you might want to
use or mount it now or in the future. Take your time. If you aren’t picking up a
strong signal where you intend to place your console, try rotating the antenna on
the console and ISS or try moving the console and ISS to different positions.
• If you have irregular terrain in the area, it may interfere with the signal. For exam-
ple, if the ISS is mounted downhill from the console, the ground may block a wide
angle of the transmitted signal.
4. Press and hold the DONE button to return to the normal screen when finished test-
ing.
Note: See the Troubleshooting section of the Vantage Pro Console Manual for information on how to
check wireless signal strength and for more information on troubleshooting reception problems.
