Specifications

This Digital Wireless transmitter is engineered to give you years of 

satisfactory service if you handle it carefully, following these guidelines:

1. The receiver is intended for indoor use only. It is not sealed against 

moisture and could be damaged if used outdoors.

2. Do not immerse the receiver in water. If you spill liquid on it, dry it 

immediately with a soft, lint-free cloth. 

3. The transmitter is weather-resistant but not waterproof. Do not 

immerse it in water or allow snow to accumulate in it. If this 

accidentally occurs, dry it immediately with a soft, lint-free cloth. 

4. Though the rain gauge is weather-resistant, it should not be left 

outdoors in snow or at temperatures at or below -4°F (-20°C).  If 

the temperature falls below this point or if snow accumulates, move 

the transmitter to an indoor area. Otherwise, permanent damage 

to the transmitter's internal circuits may occur.

5. Though the remote temperature sensor is weather-resistant, it 

should be placed away from direct sunlight, rain, or snow, and 

should never be submerged in water. If this accidentally occurs, dry 

it immediately with a soft, lint free cloth.

6. Do not mount the remote sensor on a metal surface. 

7. Do not subject the remote sensor to extremely severe temperatures. 

8. Do not place into ovens, freezers, or microwaves.

9. Do not clean any of the units with abrasive or corrosive materials. 

This may scratch plastic parts and corrode electronic circuits.

10. Do not subject any unit to excessive force, shock, dust, 

temperature or humidity. This may result in malfunction, shorter 

electronic life span, damaged batteries or distorted parts. 

11. This equipment contains no user-serviceable parts. Do not tamper 

with any unit's internal components. Doing so will invalidate the 

warranty on this product and may cause damage. 

12. Do not mix old and new batteries. Do not dispose of batteries 

in fire. Batteries may explode or leak. Remove the batteries if the 

thermometer will not be used for a long period of time.

13. Always refer to this instruction manual before operating this 

product. 

1. The receiver unit shows two temperature readings to the right of the 

clock/calendar display. The bottom readout is the temperature at the 

receiver's location. The top readout is the temperature at a remote 

sensor's location. If more than one remote sensor is set, simply press 

the  “CH”  button on the back of the receiver to toggle to another 

channel. The “CH” (Channel) Icon will indicate which channel is 

currently displayed.

2.  Press the “MAX/MIN” button once to display the highest recorded 

indoor/outdoor temperatures. Press “MAX/MIN” again to display 

the lowest recorded indoor/outdoor temperatures. Each reading will 

display for 5 seconds, and then the display will return to the current 

temperatures. 

3. To clear the Min/Max memory, press the “CLEAR” button while the 

maximum/minimum readings are displayed on the LCD.

4.  Press and hold the “MAX/MIN” button for 3 seconds to switch

How to Read Rainfall Data 

Trouble-Shooting

Transmission Collision

1. Your Taylor® Wireless Rain Gauge will track the amount of daily, 

weekly, and monthly rainfall. It will also report total accumulated 

rainfall, which is the total rainfall recorded since the unit was last 

reset to zero. Press the “-“ button to toggle between the different 

displays.

2. A signal is sent from the transmitter to the receiver every 30 

seconds when it is raining. If there is no rainfall, a signal will 

transmit every 2½ minutes. This signal will update the data on the 

receiver if any changes have occurred. 

3. As rainfall occurs, the Daily Rainfall Display will show the amount 

of rain accumulated throughout the day.  When the clock reaches 

midnight, the display for daily rainfall will automatically reset to 

zero.  

4. For the first day of rainfall, the Daily, Weekly, Monthly, and Total 

rainfall accumulation will be the same.  As additional rainfall 

occurs throughout the week/month, the unit will add the rainfall 

amounts together for a weekly/monthly/ total rainfall 

accumulation.

5. The Weekly rainfall total accumulates from Sunday to Saturday. 

When the clock reaches 12:00am (midnight) every Sunday, the 

weekly total rainfall will automatically reset to zero. 

6. The Monthly rainfall total accumulates from the first day of the 

calendar month to the last day. When the clock reaches 12:00am 

(midnight) on the first day of the month, the monthly total rainfall 

will automatically reset to zero.

7. Total Rainfall accumulates from the first day the rain gauge is put 

into use. The receiver will continue to record Total Rainfall until the 

user clears the memory or the batteries are replaced. 

8. To manually reset either the Daily, Weekly, Monthly, or Total Rainfall 

accumulations, first press the “-“ button to select the memory to be 

cleared. Press the “+” key.  The data will reset to zero.

Disconnected Signals

If the receiver unit does not receive a transmission from the transmitter 

or the remote sensor for 1 hour, the display will show dashes. 

To correct this problem:

1. Check that the transmitter and remote sensor are properly 

positioned, within a 100' transmission range.

2. Check to make sure the transmission path is clear of obstacles and 

interference.

3. If new batteries are faulty on the initial installation, install fresh 

batteries, following the steps in the Battery Installation section of 

this manual.

4.At temperatures below 32°F (0°C), the LCD readout on the remote 

sensor may fail to display. When this occurs, the sensor will still 

transmit correct temperature readings to the receiver unit, but the 

temperature can not be seen on the sensor. When the temperature 

rises above 32°F (0°C), the display will begin to function normally 

again.

Note: This equipment has been tested and found to comply with the 

limits for a Class B digital device, pursuant to Part 15 of the FCC 

Rules. These limits are designed to provide reasonable protection 

against harmful interference in a residential installation. This 

equipment generates, uses, and can radiate radio frequency energy 

and, if not installed and used in accordance with the instructions, 

may cause harmful interference to radio communications. However, 

there is no guarantee that interference will not occur in a particular 

installation. If this equipment does cause harmful interference to 

radio or television reception, which can be determined by turning 

the equipment off and on, the user is encouraged to try to correct 

the interference by one or more of the following measures: 

--Reorient or relocate the rain gauge equipment. 

--Increase the distance between the radio/television equipment   

   and rain gauge equipment.

Modifications not authorized by the manufacturer may void user's 

authority to operate this device.

Signals from other household devices, such as doorbells, home 

security systems and entry controls, may temporarily interfere with the 

rain gauge transmissions. This is normal and does not affect the 

general performance of this product. The transmission will resume 

once the interference recedes.

its original setting.

1. Follow Battery Installation and Clock/Calendar Set Up as directed 

above.

2.Place the receiver unit as close as possible to the transmitter and 

sensor (they must be within 100 feet of each other). This will 

ensure easy synchronization between the transmission and 

reception of signals as you set up your wireless system. 

3. The receiver unit should display zeros after proper battery 

installation and registration signal initialization. If the receiver still 

shows dashes, reinstall the receiver's batteries.  If the receiver 

shows a numerical rainfall value after installing the rain gauge, 

reset it by pressing the "+" button. See Battery Installation section 

for detailed instructions. 

Note: The effective transmission range of the transmitter and 

sensor is 100 feet. The effective range is vastly affected by 

building materials, physical obstructions (trees, sheds, 

fountains, etc), and where the receiver and transmitter units 

are positioned. Try various set ups for the best result. 

Shorten the distance between the receiver and transmitter 

units when necessary.  Keep the transmitter at least 3 feet 

from any obstructions which may affect rain collection. For 

instance, do not place the transmitter under a tree, as 

water dripping from leaves into the rain cup will overstate 

actual rainfall. 

4. The receiver unit is factory set to display total rainfall in inches. To 

switch measurement to millimeters, press and hold the "-" button 

for 3 seconds. The display will switch to millimeters.

5.The receiver unit is factory set to display temperature in 

Fahrenheit. To switch to Celsius, press and hold the "MAX/MIN" 

button for 3 seconds. The receiver display will switch to Celsius. 

6. The remote sensor is factory set to display temperature in 

Fahrenheit. To switch to Celsius, press the "°F/°C" button inside the 

sensor's battery compartment. The remote display will switch to 

Celsius.

7. To cancel a temperature registration, press and hold the "CH" 

button for 3 seconds. The temperature reading on the receiver 

unit will change to dashes. The registration is canceled. 

Important: When the temperature falls below freezing, the 

batteries of the remote sensor and rainfall transmitter units 

may freeze, lowering their voltage supply and effective range. 

Use Lithium batteries to insure operation below 10°F (-12°C).
