15 MINUTES: Wait 15 minutes (without pressing buttons) for the outdoor
weather data to display. If the outdoor data displays dashes, after waiting
for 15 minutes, repeat this restart.
BATTERIES
Batteries remain the #1 warranty issue we see. We advise the use of batteries
dated 6 or more years in advance of the current year. Good name brand batteries
make less noise, which reduces the chance of RF interference from the battery
compartment. If you have a voltmeter that reads numerically, a minimum voltage
of 1.48V for each battery is necessary for proper performance. Batteries dated
earlier than 6 years from now may still work, but may be unstable in performance.
MOUNTING OUTDOOR TEMPERATURE SENSOR
Please test all sensors in the house before mounting. Tip the rain gauge; blow on
the wind sensor to be sure everything reads properly. Allow the sensors to run for
2 minutes before installing batteries into the display. View all data on the display.
AVOID: Transmitting antennas, using PVC pipe (unless electrical grade), and other
sources of interference.
DO:
915 mhz functions best when all outdoor components have a minimum mount
height of 6 feet above any horizontal surface.
WIND SENSOR:
WIND: Place the Wind sensor as high as possible to install it. In most cases
6 ft above the peak of the roof (or more) is required for accurate readings.
(Avoid tall trees or other obstructions that may block or reflect the wind). A
50–foot clearance in all directions is best. For more information on wind
speed and obstructions, check this site:

Wind cups should be below the mastholder.
Ideally the Wind sensor should have a direct line of sight to the Thermohygro
sensor.
DIRECTION: Please note the proper Direction when mounting. The wind
sensor has N,S, E, W indications on the barrel. The solar panel should be
facing South for best light.
NOTE: Be sure not to overtighten the U bolts to mast, as the mastholder may
crack.
TIP:
Most meteorological recording stations have sensors mounted 33 ft or
higher above ground.
