NOTE:
– If no signals are received or the transmission is interfered, “- -” will appear on the LCD.
– Relocated the clock or transmitter in other positions and make sure the transmission is within the effective range of 30m approx.

BARO, TEMPERATURE AND HUMIDITY TREND

The Barometric pressure, temperature and humidity trend indicator shows the trends of changes in the forthcoming few minutes. Arrows indicate a rising, steady or falling trend.

BAROMETRIC/ATMOSPHERIC PRESSURE

TO SELECT THE PRESSURE DISPLAY MODE

Press and hold the [ BARO ] key for 2 seconds to enter select model that allow you select between:
abs — the absolute atmospheric pressure of your location.
rel — the relative atmospheric pressure based on the sea.

TO SET RELATIVE ATMOSPHERIC PRESSURE VALUE

1. Get the atmosphere pressure data of the sea level (it is also the relative atmosphere pressure data of your home area) through the local weather service, internet and other weather channels.
2. Press and hold [ BARO ] key for 2 seconds until “abs” or “rel” incon flashes.
3. Press [ CH / ∧ ] or [ 12/24 / ∨ ] key to switch to “rel” mode.
4. Press [ BARO ] key once again until the “rel” atmosphere pressure digit flashes.
5. Press [ CH / ∧ ] or [ 12/24 / ∨] key to change its value.
6. Press [ BARO ] key to save and exit the setting mode, or let it exit automatically 30 seconds later without pressing any key.

TO SELECT THE MEASUREMENT UNIT FOR THE BAROMETER

Use the [ BARO ] key to change the unit between hPa (mb) / inHg.

NOTE :

• When power up the main unit, it will display the relative pressure reading and default value is 1013 mb/hPa (29.91 inHg), which refers to the average atmosphere pressure.
• When you change the relative atmosphere pressure value, the weather indicators will change along with it.
• 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.

WEATHER FORECAST

The built-in barometer can notice atmosphere pressure changes. Based on the data collected, it can predict the weather conditions in the forthcoming 24 ~ 72 hours.

NOTE:

1. The accuracy of a general pressure-based weather forecast is about 70% to 75%.
2. The weather forecast is meant for the next 24 ~ 72 hours, it may not necessarily reflect the current situation.
3. The Snowy weather forecast is not based on the atmospheric pressure, but based on the temperature of current channel. When the outdoor temperature is below -3°C, the Snowy weather indicator will be displayed on the 24 HOUR FORECAST display section.

PAST 24 HOURS HISTORY PRESSURE RECORD

The current and historical atmosphere is shown near the 24 HOUR FORECAST section.
To check the pressure history in a particular hour during the past 24 hours, press the [ HISTORY ] key. Each press on the key will go back by an hour.
Under the pressure history mode, press any key (except [HISTORY ] key) to go back the normal mode, or let it exit automatically 30 seconds later without pressing any key.

MAX / MIN RECORD

The main unit preserves the MAX / MIN weather data records since the last manual reset.

1. In normal mode, press [ MEM ] key once to show the indoor & current outdoor channel maximum temperature and humidity records.
2. Press [ MEM ] key repeatedly to show the minimum records.
3. Press [ MEM ] key again to exit.
4. To erase all the MAX / MIN records, press and hold [ MEM ] key for 3 seconds.

MOON PHASE

The main unit can show the northern hemisphere moon phase status, below is the table which illustrate how the moon will appear on the main unit.

LOW BATTERY ICON

When the battery indicator appear on the clock section or the LCD becomes dim, replace with 2 new AA size batteries at once; while If the low battery indicator appear in the outdoor section, it indicates that the battery power of the transmitter is not enough, and you should replace with 2 x AA size batteries at once.
