rain,” or the reverse. It will not change from
“sunny” directly to “rainy,” although it is possible
for the change to occur quickly. If the symbols do
not change then the weather has not changed, or
the change has been too slow and gradual to
register.
B. WEATHER TENDENCY ARROWS
Other possible displays in the FORECAST LCD
are 2 weather tendency arrows, one that points up
(under the forecast icons) and one that points
down (above the forecast icons). These arrows
reflect current changes in the air pressure. An
arrow pointing up indicates that the air pressure is
increasing and the weather is expected to improve
or remain good, an arrow pointing down indicates
that the air pressure is decreasing and the
weather is expected to become worse or remain
poor. No arrow means the pressure is stable.
II. OUTDOOR TEMPERATURE
The Weather Temperature Station receives the outdoor
temperature ( F or C) from the Remote Temperature
Transmitter, and the temperature appears in the
OUTDOOR LCD. The Remote Temperature
Transmitter makes a temperature update every 1
minute, and transmits a new temperature to the
Weather Temperature Station 3 times every 10
minutes.
