replacement.
1. After mounting the anemometer, loosen the screws on the battery door with a small screwdriver and
open the battery door.
2. Use the compass on the anemometer and turn the wind vane so it is pointing due north.
3. Hold the wind vane pointing due north and do not allow it to turn. Insert 2 pieces of AA batteries
according to the polarity indicated. The red LED indicator above the battery cover of the
anemometer will flash few times right after battery installation. Be sure the vane is pointing due
north at the moment when red LED flashes and the calibration is now completed. Replace the
battery cover and tighten the screws.
4. If the wind vane is not pointing due north when the red LED first flashes, remove batteries and
repeat step 2 & 3.
5. Hold "CHANNEL/SEARCH" buttons on the monitor to search for remote transmitter. Wind direction,
wind speed, wind chill & channel-1 temperature/humidity readings will appear within 10 minutes if
the RF transmission is successful.
5. Selecting a location for the rain gauge
Select a mounting location for the rain gauge that is:
- a flat, level surface. Look for a location where the rain gauge can be placed 1 meter or more
above ground level.
within 30 meter (100 feet) open area from the monitor. Reduce distance if obstacles is between
-
the rain gauge & the monitor
in an area not blocked on the top or sides, so rain can freely reach the rain gauge (for example,
-
not under an overhang or too close to a building or fence)
