6. If the weather signal becomes “Detected,” the
“No Paging Signal” message will discontinue.
Monitor the signal Accuracy percentage for
several days.
7. If the signal remains “Not Detected” after com-
pleting the steps above, try a different installa-
tion location or an optional external antenna.
Note:
Because of the nature of radio transmission,
strength of the paging signal may vary depending
upon your location. An external antenna may be
used in some areas to eliminate signal weakness-
es, see chapter 2, Installation, for more informa-
tion on optional external antennas.
Note:
The Reset command also clears the test
counter.
Note:
In the Automatic Control Mode, when
weather signals are missed the ET Manager will
automatically calculate ET for the missed signals.
Even though signals are missed, the ET Manager
will continue to operate using stored ET and
Historical ET values.
Signal Accuracy
Your ET Manager checks and stores data received in the
weather signal. If data reception accuracy is less than
65% then the “X% of Signal Accuracy” Attention mes-
sage will come on. For example with a signal accuracy
of 58%, the Home screen will display “58% of Signal
Accuracy.”
In the Automatic Control Mode, when weather signals
are missed the ET Manager will automatically calculate
ET for the missed signals. Even though signals are
missed, the ET Manager will continue to operate. If
weather signals are not received for more than a day
then the ET Manager will calculate ET based on weather
data from the last 7 days. If there is no weather signal
received for more than a week then the mode automati-
cally uses the pre-programmed Historical ET values.
The proper action to take when the signal accuracy is
less than 65% depends on duration. If your ET
Manager has missed data for a few days and the signal
accuracy becomes low, there may not be a significant
problem with your ET Manager or the weather signal.
However, if your ET Manager has missed data for two
weeks or more, it is likely there is a problem in need of
fixing.
Actions to take:
Low Accuracy percentages can result
from several conditions:
1. If power is off for a period of time the weather
signal is not received. When power is restored
your ET Manager determines that messages
have been missed. Over time the Accuracy
percentage will increase and the Attention
Indicator Light will go off.

2. Weak radio reception or radio interference may
cause missed weather signals. An external
antenna may be needed to improve radio
reception. Contact Rain Bird to find out more
information about an optional external anten-
na, refer to chapter 2, Installation.
3. It may be that your WRSP had system problems
that interrupted the weather signal for a period
of time. If data continues to be missed for sev-
eral days, contact your WRSP, to check if there
has been interruption in the weather signal.
4. Occasionally, the paging system may malfunc-
tion. If data continues to be missed for several
days, contact your WRSP to see if they are
aware of any problems.
Note
: All missed messages are replaced with a cal-
culated ET value based on previously received
weather information and the historical ET pro-
grammed in your ET Manager.
