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.

Sunny

Partly Cloudy

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 

UHÀHFWWKHFXUUHQWVLWXDWLRQ

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

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.

IMPORTANT NOTE

 

- This main unit is intended to be used only indoors.

 

- Do not subject the unit to excessive force, shock, dust, temperature or humidity.

 

- Do not cover the ventilation holes with any items such as newspapers, curtains etc.

 

- Do not immerse the unit in water. If you spill liquid over it, dry it immediately with a 

soft, lint-free cloth.

 

- Do not clean the unit with abrasive or corrosive materials.

 

- Do not tamper with the unit’s internal components. This invalidates the warranty.

 

- Only use fresh batteries. Do not mix new and old batteries.

 

- Do not dispose old batteries as unsorted municipal waste. Collection of such waste 

separately for special treatment is necessary.

 

- Attention! Please dispose of used unit or batteries in an ecologically safe manner.
