1. Unscrew the anemometer from the wind sensor  
carefully.  
For continuous use, please install the AC adaptor. The  
batteries are for back-up use only.  
2. Insert batteries matching the polarities (+ / -) and  
replace the anemometer. Press RESET after each  
battery change.  
NOTE Make sure the adaptor is not obstructed and is  
easily accessible to the unit.  
NOTE The base station and adaptor should not be  
exposed to wet conditions. No objects filled with liquid,  
such as vases, should be placed on the base station  
and adaptor.  
SET UP REMOTE TEMPERATURE / HUMIDITY  
SENSOR  
The remote sensor can collect data from up to 3 channels.  
To completely disconnect from power, unplug adaptor  
from the mains.  
To set up the remote sensor:  
1. Slide open the battery door.  
2. Slide channel switch to select a channel (1, 2, 3).  
Ensure you use a different channel for each sensor.  
3. Insert the batteries, matching the polarities (+ / -).  
4. Press RESET after each battery change.  
5. Close the battery door.  
To insert batteries:  
SET UP RAIN GAUGE  
The rain gauge collects rain and takes rainfall readings.  
The sensor can remotely transmit data to the base  
station.  
1. Slide open the battery door.  
To set up the rain gauge:  
2. Insert the batteries, matching the polarities (+ / -).
