If You Do Not See Current Wind Readings
First, verify that the console/receiver is powered and is not in Setup Mode (exit
Setup Mode by pressing DONE key and holding it for a moment). Then, on the
transmitter, ensure that the anemometer sensor cable is firmly plugged into the
jack that is labeled “WIND” on the SIM. Check that the battery is properly
installed. Walk around the room with the console, standing for a few moments
in various locations to see if you are picking up signals.
If you don’t see wind readings no matter where you stand with the console,
put your anemometer transmitter in TEST mode.
TEST mode
DIP switch #4 on the SIM (see illustration on page 6) is the TEST DIP-switch.
Switch it to the ON position using a ball-point pen or paper clip. This puts the
transmitter in
Test Mode. An LED indicator light will flash each time it trans-
mits:
✦ The LED will immediately flash once to show that the light itself functions.
✦ Then it will flash each time the transmitter broadcasts a signal, which should be
every 2.5 seconds.
If the LED flashes only once and then remains dark, there is a problem with the
anemometer transmitter. See “Contacting Davis Instruments” on page 15.
If the LED flashes repeatedly but your console isn’t picking up a signal any-
where in the room, it could be related to one of the following causes:
1. The DIP switches were not correctly set on the transmitter.
Review the procedure on page 5.
2. The ID was not correctly set on the console/receiver.
Review the procedure on page 7.
3. Reception is being disrupted by RF (radio frequency) interference.
Interference has to be very strong to prevent the console from receiving a
signal while in the same room as the anemometer transmitter!
4. There is a problem with the console/receiver.
See “Contacting Davis Instruments” on page 15.
Note: Remember to turn the Test DIP switch OFF when you’re finished testing wireless transmis-
sion. If it is left ON, the blinking LED will reduce battery life significantly.
