temperature readings at about 45 second intervals. The remote rain
gauge will transmit rainfall data at about 183 second intervals. The main
unit may take up to two minutes to receive the initial readings. Upon
successful reception, the rainfall reading (0.00) will appear on the top line
of the main unit’s display and the remote temperature will appear on the
line below. The main unit will automatically update readings at 45-second
intervals.
