BATTERY INSTALLATION AND ACTIVATION
Notes:
Always replace all batteries at the same time; do not mix old and new batteries. Do not mix alkaline,
standard (carbon-zinc) or rechargeable (ni-cad, ni-mh, etc.) batteries.
For maximum performance in normal conditions we recommend using good quality alkaline batteries.
When temperatures are near or below freezing (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 near or below
freezing, we recommend using lithium batteries to minimize the loss of transmission.
NOTE: please recycle or dispose of batteries per local regulations.
WARNING: Batteries may pose a choking hazard. Do not let children handle batteries.
PRECAUTION: Do not dispose of batteries in fire. Batteries may explode or leak. Remove the batteries if the
thermometer or remote sensor will not be used for a long period of time.

access the RESET/RE-SYNC buttons. (Diagram 2)
Using a coin, unscrew the battery door at the bottom of the rain collector and insert (2) AA batteries
according to the polarity markings.
Press the RESET button.
Replace the battery door. Make sure the door is closed securely to prevent water leakage.
Remove the tape from the pendulum inside to allow it to move freely.
Close the outer case.
When the OUT temperature is shown on the display of the base unit, synchronization between the base unit
and the remote sensor is complete.
POWER UP SYNCHRONIZATION
The base unit will search for the RF (radio frequency) signal from the rain collector for 6 minutes after reset or
after batteries are inserted. When the temperature display on the main unit shows the OUT temperature,
synchronization between the base unit and remote unit is complete.
The top, left of the base unit display will show the icon to indicate signal transmission. If the OUT
temperature does not show on the display within 6 minutes after reset, press the RE-SYNC button and the main
unit will search for the RF signal for another 6 minutes. If the base unit still fails to show the out temperature,
refer to the LOSING SYNCHRONIZATION section.
Locating the Base Unit and Remote Sensor
Choose a suitable place for the base unit and remote outdoor sensor, within the transmission distance.
Place the base 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 sensor is designed to
transmit unimpeded 80 to 100 feet. 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 collector must be placed on a level, horizontal surface for accurate rainfall measurement.
Use the enclosed screws to mount the rain collector on a solid surface or use the metal spikes to secure the
unit in a grassy area.
Warning: Ice will affect the accuracy of rainfall readings and will damage the internal mechanism of the
rain collector. In temperatures below freezing the collector 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.
