Siting the ISS and Anemometer: General ISS Siting Guidelines:

• 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.
