The default relative atmospheric pressure value is 1013
mb/hPa (29.91 inHg), which refers to the average atmo-
spheric pressure.
10. When you change the relative atmospheric pressure
value, the weather indicators will change along with it.
11. The built-in barometer can notice the environmental
absolute atmospheric pressure changes. Based on the
collected data a forecast for the weather conditions in
the next 12 hours can be made. Therefore, the weather
indicators will change according to the detected abso-
lute atmospheric pressure after you operate the clock
for 1 hour.
12. The relative atmospheric pressure is based on the sea
level, but it will change with the absolute atmospheric
pressure changes after operating the clock for 1 hour.
18 Connecting remote sensors
The Weather Station can display the readings from up to 3
wireless sensors* of the same type. Each radio sensor must
be set to a separate channel. Proceed as follows to set the
channel:
1.
Remove the battery compartment cover of the wireless
sensor.
2.
Set the channel selection switch to the desired channel
(CH1, CH2 or CH3).
3.
Re-attach the battery compartment cover.
4.
NOTICE! Each connected wireless sensor must be set to
a different channel. If only one wireless sensor is con-
nected, it should be set to CH1.
5.
Press the CH/UP button on the base station several
times to display the measured values for the individual
channels. The selected channel is shown in the display.
