SETTING UP  
Hint: Use good quality Alkaline Batteries; avoid rechargeable  
batteries.  
1. Have the receiver and the rain gauge 3 to 5 feet apart.  
2. Place the batteries into the rain gauge FIRST and next into  
the receiver. Observing the correct polarization, insert 2 “AAA”  
Alkaline Batteries into the compartment at the back of the rain  
gauge and replace the cover. Follow the same guidelines for  
the receiver.

3. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.  
4. All segments of the LCD will light up briefly. Then 0.00 inch will  
be displayed in both sections of the LCD. If the “0.00” is not  
displayed after a few seconds, remove the batteries and wait  
for at least 10 seconds before reinserting them.  
5. Place the rain gauge in an appropriate location. The rain  
gauge should be placed in a secure and flat location where it  
can properly collect properly rain quantity without obstruction.  
The rain gauge has a range of 330 feet. Keep in mind that the  
330 feet is in open air with no obstructions and that radio  
waves DO NOT curve to go around objects. Real-world  
transmission range will vary depending on what is in the path  
of the signal. Each obstruction (roof, walls, floors, ceilings,  
thick trees, etc.) will effectively cut signal range in half.  
Example: A wireless rain gauge receiver with a 330 feet  
range is mounted on an interior wall, so that the signal has to  
pass through one interior wall, one exterior wall, and across  
the 10 feet width of the room between the 2 walls. The first  
wall will reduce the range to 165 feet, and the second wall will  
reduce the range to 87 feet. Factoring in the 10 foot room, this  
leaves a maximum of 77 feet of remaining signal range.  
This allowance is typically enough for a frame wall with non-  
metallic siding; however certain materials can reduce range  
even further. Metal siding, stucco, and some types of glass  
can reduce signal range by as much as ¾ or more, compared  
to the ½ reduction typical of most obstructions. It is possible to  
receive a signal through these materials, however maximum  
range will be much less due to their tendency to absorb or  
reflect a much larger portion of the sensor’s signal.  
Note:  
When opening the battery cover make sure that the batteries do  
not spring free from the contacts since this will cause start and  
transmission problems.

Battery Change:  
It is recommended to replace the batteries in the unit

The Light Rain icon will appear if any rain  
is registered over the past 10 minutes.  
Heavy Rain: Indicated by 3 clouds with  
animated rain.  
The Heavy Rain Icon will appear if more  
than 10 counts (0.2”) have been  
registered over the past 10 minutes.  
Low Battery Indicators (RX & TX)  
RX: Indicates the receiver battery is low.  
TX: Indicates the rain gauge battery is low.  
MOUNTING  
Positioning the Receiver:  
The Receiver can be positioned on a flat surface or on a wall.  
Foldout Table Stand  
The foldout table stand is located on the backside of the Receiver.  
Carefully pull out the stand and place the Receiver in the desired

Positioning the Rain Gauge  
Position the connected rain gauge outdoor to collect rainfall data.  
Ensure that the rain gauge is placed in a secure and flat location  
where it can properly collect properly rain quantity without  
obstruction. Ensure also that the rain gauge is securely mounted  
at the appropriate location otherwise it may not transmit accurate  
rainfall data.  
The rain gauge must be level to transmit correct readings. It is  
recommended to mount the rain gauge 3 feet or higher off of the  
ground. Screw the rain gauge down snugly in the holes provided  
(but not too tight as this will affect the accuracy of the gauge).

MAINTENANCE  
Avoid placing the units in locations prone to extreme  
temperatures, vibration and shock since these may cause  
damage and inaccurate readings.  
When cleaning the display and casing of the Wireless Rain  
Gauge, use a soft damp cloth only. Do not use solvents or  
scouring agents as they may mark the casing and LCD.  
Do not submerge the Wireless Rain Gauge in water.  
Immediately remove all low powered batteries to avoid leakage  
and damage. Replace only with new batteries of the  
recommended type.  
Please do not make any attempt to make any repairs to the  
units. Return them to their original point of purchase for repair  
by qualified personnel. Opening and tampering with the units  
will invalidate the warranty.
