TEST mode
DIP switch #4 on the SIM (see illustration on page 4) 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 transmits:
✦
The LED will immediately flash once to show that the light itself func-
tions.
✦
Then it will flash each time the transmitter broadcasts a signal, which
should be every 10 seconds.
If the LED flashes only once and then remains dark, there is a problem with
the transmitter. See “Contacting Davis Technical Support” on page 10.
If the LED flashes repeatedly but your console isn’t picking up a signal
anywhere 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 3.
2. The ID was not correctly set on the console/receiver.
Review the procedure on page 5.
3. Reception is being disrupted by RF (radio frequency) interference.
4. There is a problem with the console/receiver.
See “Contacting Davis Technical Support” on page 10.
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.
Choosing a Location for the Soil Moisture Station & Sensors
The Watermark  soil moisture sensors should be located at root depth for best
results. Shallow rooted crops with a root depth of less than 12” may only
require one soil moisture sensor. Deeper rooted row crops, small grains, vines
and trees generally require sensors located in at least two depths. The basic
principal is that the sensors must be located within the effective root system of
the crop. Guidelines on proper depths for specific crops and conditions can be
obtained from your local farm advisor.
While not absolutely necessary for operation, we also recommend that a tem-
perature probe be installed with each soil moisture sensor. This allows the soil
moisture sensor’s readings to be temperature compensated for better accuracy.
Range of Wireless Transmission
The range of wireless transmission depends on many factors. For the best
reception, position the transmitter shelter and your console/receiver as close
together as possible.
