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
approximately every 3 years to ensure optimum accuracy.
FUNCTION KEYS
The simple design of this product features 2 keys.
RESET/+ Key:
•Press for 5 seconds to reset the TOTAL rainfall data “0”.

•To view the alarm pres and hold the ALM/SET button. This
will cause the receiver to beep if the set alarm value has
already been reached.
Resetting TOTAL RAINFALL and 24 HOUR RAINFALL
•Total Rainfall: Press and hold the RESET/+ button. The
receiver will beep, and the total rainfall will reset to 0.00”.
•24 Hour Rainfall: To reset the 24 Hour Rainfall to “0.00”,
remove the batteries, wait 2 minutes, and then re-insert the
batteries.
Note: The 24H Rainfall will not reset to “0.00”. Instead the value
will update every hour.
The 24H Rainfall will only show “0.00” if there is no rainfall for a
full period of 24 hours.
Light Rain/Heavy Rain Indicator
The wireless rain gauge features 2 rain level indicators: Light
Rain and Heavy Rain.
Light Rain: Indicated by 3 clouds and
rain with no animation.
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
location.
Wall Mounting
Place a screw in the desired location leaving the head extended
about ¼” from the wall. Hang the Receiver on the screw ensuring
that the Receiver locks into place.
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.
