Warning:
- Do not mix old and new batteries.
- Do not mix alkaline, standard (carbon zinc). or rechargeable (nickel cadmium) batteries.
- For maximum pertomance in normal conditions we recommend using good quality
alkaline batteries When temperatures are below 32°F (0°C), alkaline batteries can lose
power resulting in a loss of remote transmission. If you reside in an area that
experiences frequent temperatures below freezing. we recommend using lithium
batteries to minimize the loss of transmission.
SET UP PROCEDURE
Main Unit
Remove Insulation strip from 4pcs AAA batteries of Main Unlt
Setting the Calendar, Clock, °c I °F
' When either the clock or calendar is being displayed, press and hold the MODE button
for 3-4 seconds until the year display is flashing
- Press + or — to set the year
Press MODE to display the date
Press + or — to set the month and day
Press MODE to display time
Press + or — to set the time
Press MODE and the display will show 12 hr
Press + or — to set your clock to 12 hr or 24 hr time format
Press MODE and the temperature field will be flashing
Press + or — to select ”F or “C format
Press MODE to lock in the settings
Note: If you set the time and date after initial activation. the accuracy of the rainfall history
data may be affected. Reset the unit to clear the history by pressing the RESET button
then set your desired time and date
Remote Unit
- Detach the other case of the rain gauge unit.
- Remove the tape from the bucket to allow it to move freely.
- Unclip and raise the inner cover to access RESET/H E-SYNC buttons.
- Press the RESET button to resume operation from sleep mode.
- Close the inner cover.
- Close the outer case.
POWER UP SYNCHRONIZATION
Position the wireless rain gauge close to the receiver. The receiver will search for the RF
signal from the rain gauge for 6 minutes after reset or after batteries are inserted. Then,
the receiver will refrech the RF temperature every 3 minutes. When the temperature
display on the main unit shows the OUT temperature, synchronization between the main
unit and remote unit is completed.
The top left of the main unit display will show the out icon to indicate signal transmission. if
the OUT temperature does not show on the display within 6 minutes after reset (or
batteries installation), press the FlE-SYNC button on the main unit and rain collector, the
main unit will search for the RF signal for another 6 minutes. It the main unit still fails to
show the out temperature. refer to the LOSING SYNCHRONIZATION section.
Locating the Main Unit and Remote Unit
Choose a suitable place for the base unit and remote unit within the transmission
distance.
- Place the main unit near a window, but away from direct sunlight or sources of heat or
air conditioning to ensure accurate temperature readings.
- The location you choose is critical for maximizing the transmission range. The remote
unit is designed to transmit unimpeded 80 to 100ft (24.4 to 30.5m ). Transmitting
through walls, metal doors and metal framed windows may reduce the transmission
range. To optimize the transmission distance. the remote unit should be positioned in a
location that minimizes these obstructions. Other interference from electrical sources
such as home security systems. wireless doorbells and wireless home entertainment
equipment may interrupt the transmission signal temporarily.
Notes:
- The outdoor rain gauge must be placed on a level, horizontal surface for accurate
rainfall measurement.
~ Use the enclosed screws to mount the rain gauge on a solid surface or use the metal
spikes to secure the unit in a grassy area.
~ Warning: lce will affect the accuracy of rainfall readings and will damage the internal
mechanism of the rain gauge. In temperatures below freezing the rain gauge can remain
outdoors for temperature data transmission. but the unit must be placed in a protected
area to prevent ice damage.
INDOOR AND OUTDOOR TEMPERATURE
~ The indoor temperature is shown after activation until the first outdoor temperature
signal is received. The display will then change to the outdoor temperature reading.
o Press the lN-OUT TEMP button to toggle between indoor and outdoor temperature.
- To activate Auto Scroll mode, press and hold the lN-OUT TEMP button for 3-4 seconds.
Double curved arrows will show at the top of the LCD display and the unit will
automatically toggle between indoor and outdoor temperature. Press and hold the
lN-OUT TEMP button for 3-4 seconds to de-activate Auto—Scroll mode.
- The temperature trend arrow which is located directly above the temperature reading
will indicate the trend of indoor and outdoor temperatures during the last three minutes.
