• Press the “C” button (17) briefly and repeatedly until the arrow symbol (5)
appears at the desired channel (if the external sensors are registered with channel
4 - 8, choose the corresponding channel number).
• Press and hold simultaneously both of the “ALARM/ADJUST” (16) and “MIN/
MAX/” (15) buttons for 5 seconds.
As a result, the air humidity value begins to flash.
• Change the air humidity value with the “MIN/MAX/-” (15) or “C” (17) but-
ton. Press and hold the corresponding button for a longer period of time for a quick
adjustment.
• If the air humidity value needs to be reset back to the non-calibrated output value,
press briefly the “ALARM/ADJUST” button (16).
• To save the calibrated value and leave the set-up mode, press and hold the “ALARM/
ADJUST” button (16) for 3 seconds.
The set-up mode will be automatically ended when you do not press any button for a
few seconds. In that case the base station uses the previous settings.
