For continuous use, please install the AC adapter. The batteries are for back-up use
only.
NOTE Please make sure the socket-outlet is installed near the equipment and is
easily accessible.
SET UP REMOTE RAIN GAUGE
The rain gauge collects rain and takes readings of the total rainfall over a period of
time. The sensor can remotely transmit data to the base station.
Install the base station batteries (4 x UM-3 / AA) matching the polarity + and -. Press
RESET after each battery change.
The base station and rain gauge should be positioned within effective range: about
100 meters (328 feet) in an open area.
NOTE Do not use rechargeable batteries. It is recommended that you use alkaline
batteries with this product for longer performance.
The rain gauge should be mounted horizontally about 1 meter (2-3 feet) from the
ground in an open area away from trees or other obstructions to allow rain to fall
naturally for an accurate reading.
The battery icon indicator
may appear in the following areas:

CLOCK RECEPTION
This product is designed to synchronize its calendar clock automatically once it is
brought within range of a radio signal:
3. Put a few drops of water on the cross at the base of the funnel to check the
horizontal level. Water will pool to the center of the cross when the rain gauge is
level.

NOTE For best reception, the base station should be placed on a flat, non-metallic
surface near a window in an upper floor of your home. The antenna should be placed
away from electrical appliances and not be moved around when searching for a
signal.
