When you change the relative atmosphere pressure
value, the weather indicators will change along with it.
The built-in barometer can notice the environmental
absolute atmosphere pressure changes. Based on the
data collected, it can predict the weather conditions in
the forthcoming 12-24 hours. Therefore, the weather
indicators will change according to the detected absolute
atmosphere pressure after you operate the clock for 1
hour.
The relative atmosphere pressure is based on the sea
level, but it will change with the absolute atmosphere
pressure changes after operating the clock for 1 hour.

”will appear on the LCD.
symbol “
The unit has already synchronized with the time signal
transmitter. Otherwise the segment will disappear from the
LCD display.
NOTE:
You may use the “°C/°F” key to receive the time signal
manually. Be caution of using the RECEIVE mode, which
will consume more battery power and thus may reduce the
battery lifetime. The RECEIVE mode will be off automatically
in 6-12 minutes.
RELATIVE ATMOSPHERE PRESSURE SETTING
SUGGESTION:
The “rel” display on the LCD is the abbreviation of “relative”,
which refers to the relative atmosphere pressure based on
the sea level; while “abs” is the abbreviation of “absolute”,
which means the absolute atmosphere pressure of your
location. You can set the relative atmosphere pressure value
according to the following steps:
