E. Operation and Display

To save battery power, the sensor sends reading automatically only

when the temperature/humidity change is over 1℃/3%. If there is no any

change for a long time, the sensor will send the reading hourly to refresh the

display.

If there is any new reading transmitted from the sensor, the Base Unit will keep

the last reading on the display alternatively with the time display each for 5

seconds. You can clear the reading by Hot Key C.

Alarm Device: The system issues alarm when the reading is over the limits and

issues restore signal when the reading returns to the limits.
