Operation Manual

hPa / inHg PRESSURE UNIT SETTING:

Digit flashing

The pressure display can be selected to show relative air pressure in hPa

or inHg (default is “hPa”).

Digit flashing

1. Use the OUT/+ key to toggle between “hPa” or “inHg” unit

2. Confirm with the SET key and enter the Relative air pressure

value setting.

Note: Units of weather icon sensitivity and air pressure history are not

affected. They are always expressed in hPa.

RELATIVE AIR PRESSURE VALUE SETTING

The default relative pressure value is 1013 hPa (29.92 inHg). This can be

manually set to another value within the range of 960 – 1040 hPa (28.35 –

30.72 inHg) for a better reference.

Digit flashing

1. The current relative pressure value will start flashing

2. Use the OUT/+ key to increment and IN key to decrement the value.

Keep holding the key allows the value to advance faster.

3. Confirm with the SET key and enter the Weather forecast icon

sensitivity setting.

WEATHER FORECASTING ICON SENSITIVITY SETTING:

For locations with rapid changes of weather conditions, the weather icons

sensitivity can be set to a different level for faster display of weather

conditions.

1. The current sensitivity value will start flashing.

2. Use the OUT/+ key to set the weather sensitivity level. There are 3

levels of setting: 2, 3 and 4. The value corresponds to the change of

air pressure in hPa before the weather icon will switch to another

state. Level 2 is the most sensitive setting, level 4 is the slowest

recording setting (default setting is "3").

3. Confirm with the SET key and exit the Manual settings.
