1. If the signal for the current channel has discontinued and does not recover within 1 hour, the signal icon will disappear. The temperature and humidity will display “Er” for the corresponding channel.
2. If the signal does not recover within 48 hours, the “Er” display will become permanent you need to replace the batteries of  “Er” channel’s sensors and then press the [ SENSOR ] key to pair up the sensors of each “Er” channel again.

NOTE:
After replacing the batteries of the wireless sensor or the unit fails to receive the wireless sensor signal of a specified channel. During the failed channel is displaying, press [ SENSOR ] key to manually receive that sensor signal again.
VIEW CHANNEL OF MULTIPLE WIRELESS SENSORS
This main unit can support up to 8 additional wireless sensor(s).
If you buy the additional wireless sensor(s) and paired with the main unit. Then, you can press [ CH / + ] key to switch the display between CH 1~8. In normal mode, press and hold [ CH / + ] key for 2 seconds to enter auto-cycle mode, after a bi sound, it will alternately display the channels at 4-second intervals.

3. During auto-cycle mode, press [ CH / + ] key once to stop auto-cycle and display the current channel.
4. Using auto-cycle mode will only display the communicated channels. For example, when CH 1 and 6 have received the signal from the corresponding sensor, press and hold [ CH / + ] key for 2 seconds will only toggle the readings of CH 1 and 6. Other channels will be neglected.

THE SNOW ICON

When the outdoor temperature is 3°C or below, the flashing snow icon “ ” will appear in outdoor section.

WEATHER FORECAST
The device contains a sensitive pressure sensor built-in with sophisticated and proven software that predicts weather for the next 12 ~ 24 hours within a 30 to 50 km (19-31 miles) radius.

NOTE:

1. The weather forecast is meant for the next 12 – 24 hours, it may not necessarily reflect the current situation.
2. The weather icon will flash on display when the rainstorm comes.
3. The SNOWY weather forecast is not based on the atmospheric pressure but based on the outdoor temperature. When the outdoor temperature is below -3°C (26°F), the
   SNOWY weather indicator will be displayed on the LCD.

BAROMETRIC/ATMOSPHERIC PRESSURE
TO SELECT THE PRESSURE DISPLAY MODE

1. Press and hold the [ BARO ] key for 2 seconds to enter select model:

2. Press [ CH / + ] key or [ MEM / – ] key to select between:
   – abs — the absolute atmospheric pressure of your location.
   – rel — the relative atmospheric pressure based on the sea.

3. In “abs” mode, press [ BARO ] key to exit, In “rel” mode, press [ BARO ] key to set relative atmospheric pressure value in next section.

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 the [ BARO ] key for 2 seconds until abs or rel icon flashes.

3. Press [ CH / + ] key or [ MEM / – ] key to switch to RELATIVE mode.

NOTE:
– When powering up the main unit, it will display the relative pressure reading and the default value is 1013 MB/hPa (29.91 inHg), which refers to the average atmospheric pressure.
– When you change the relative atmospheric 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.

HEAT INDEX / DEW POINT
TO VIEW HEAT INDEX
Press the [ INDEX ] key repeatedly to show the HEAT INDEX value.

NOTE:
Heat index is only calculated when the temperature is 27° C (80° F) or above and based solely on the temperature and humidity measured from the outdoor wireless sensors.
TO VIEW DEW POINT
Press the [ INDEX ] key repeatedly to show DEW POINT value.

NOTE:
The dew point is the temperature below which the water vapor in air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates. The condensed water is called dew when it forms on a solid surface. The dew point temperature is calculated from the outdoor temperature and humidity measured at the outdoor wireless sensors.

HISTORY DATA (WEATHER RECORDS IN THE PAST 24 HOURS)
The main unit will record the past 24 hours of weather data automatically that including past indoor and outdoor temperature & humidity, Baro, and Dew point/heat index records.
