CLEARING ALL STORED TEMPERATURE AND HUMIDITY DATA (FROM

TEMPORARY MEMORY OF THE TEMPERATURE STATION)

area where the latest data will displace the oldest data once the memory capacity is reached). To clear this

memory, the following step shall be performed:

1. Press both the Plus key and SET key and hold for about 2 seconds. Only the temperature and

humidity records of all channels (indoor and the outdoor channels) will be cleared. So the average

and history data will no longer exist. The memory display will show “mem 0000” after the data has

been cleared.

Note: The maximum/ minimum temperature and humidity data will not be cleared.
