Note:
The radio communication between the receiver and
the transmitters
in the open field reaches distances of max 330 feet, provided there are no interfering obstacles such
as buildings, trees, vehicles, high voltage lines, etc.
9.
Radio interferences created by PC screens, radios or TV sets can in some cases entirely cut off radio communication. Please
consider this
when choosing standing
or mounting locations.
Note :
•
After batteries are installed in the transmitter, install the batteries in the weather center to receive the signal from
the transmitters
as soon as possible. If the weather
center is powered more than 5 hours after the transmitter is powered, the weather center will never receive signal successfully from
the transmitters
. In this case,
user will need to reinstall the batteries from
all the transmitters
to redo set-up procedure.
•
After batteries are installed, there will be synchronization between weather center and
the transmitters.
At this time, the signal reception icon will be blinking. When
the signal is successfully received by the weather center, the icon will be switched on. (If it is not successful, the icon will not be shown in LCD) So the user can
easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is in progress.
•
If the signal reception is not successful on the first frequency (915MHz) for
45 seconds
, the frequency is changed to 920MHz and the learning is tried another
45
seconds
. If still not
successful,
the reception is tried for
45 seconds
on 910MHz. This will also be done for re-synchronization.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-HYGRO SENSOR
The outdoor Thermo-hygro sensor works with 2 x AA, IEC LR6 1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Uninstall the rain cover of the transmitter.
2.
Remove
the battery compartment cover.
3. Insert the batteries, observing the correct polarity (see the marking in the battery compartment).
4. Replace the battery cover.
Note:
In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a random security code is assigned
by the thermo-hygro sensor at start-up and this code must be received and stored by the Weather Center in the
first several minutes
of power being supplied to it.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE RAIN SENSOR
The rain sensor works with 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries, please follow the steps below:
1.
Press tabs back to unlock rain sensor cover. (Figure 1)
2.
Lift rain sensor cover to access battery compartment. (Figure 2)
3.
Insert the batteries, observing the correct polarity (see the marking in the battery compartment). (Figure 3)
4.
Replace the battery cover and the rain cover onto the unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a random security code is assigned
by
the rain sensor at
start-up and this code must be received and stored by the Weather Center in the first several minutes of power being supplied to it.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER CENTER
The Weather Center works with 3 x AA, IEC LR6, 1.5V batteries. When the batteries need to be replaced, the low battery symbol will
appear on the LCD. To install and replace the batteries, please follow the steps below:
1.
Remove the battery compartment cover.
2.
Insert the batteries observing the correct polarity (see the marking in the battery compartment).
3.
Replace the battery cover.
BATTERY CHANGE:
It is recommended to replace the batteries in all units every 24 months to ensure optimum accuracy of these units.
Please participate in the preservation of the environment. Return used batteries to an authorized depot.
Note:
The stored History record will not be kept after the battery change is done on the Weather Center.
