LED BACKLIGHT OPTIONS

The main unit backlight can be turned on, off or automatically toggled depending on the environment

light conditions. Use the light sensor switch at the back of the main unit to select a desired backlight

setting.
For the automatic backlight control, the sensitivity of the light sensor can be adjusted to high or low

using the switch, located on the back panel.

NOTE:

For an automatic control function the main unit must be plugged into the wall power outlet via

the AC/DC adaptor provided.

USING DIFFERENT WEATHER MODES
PRESSURE AND WEATHER FORECAST MODE

It indicates the current barometric pressure, the sea level pressure, the weather forecast and the moon

phase.
A number of historical statistics can also be viewed, including the sea-level pressure for the past 

24 hours, moon phase for the past and following 39 days, as well as a pressure/ temperature/ humidity

history bar-chart.
Pressure can be displayed inHg, hPa/mBar or mmHg, and altitude can be displayed in meters or feet.

(Altitude can be used to set or adjust barometric levels.)

ACCESSING PRESSURE AND WEATHER FORECAST MODE

From the main unit: Press 

UP

or 

DOWN

until the pressure and weather forecast icon 

starts flashing.

SETTING PRESSURE PARAMETERS DURING INITIAL SETUP

IMPORTANT:

During the main unit initial setup, after main unit powered up, all of the functions in

Pressure and Weather.

Forecast mode will be locked for a short time, until the pressure settings are confirmed. The locked
display will show the pressure and weather forecast icon and abbreviation “
