INTRODUCTION

Congratulations on your purchase of the BAA898HG Long-Range
Wireless Weather Station with In-Out Thermo-Hygrometer. This
unit is an all-in-one weather forecasting device which has multiple
weather-related functions. Also, with an internal antenna the
reception range of this unit can be up to 100 meters.

In addition to indoor temperature and humidity, by means of
wireless remote thermo-hygro sensor it can simultaneously
monitor temperatures and humidities in up to 3 remote locations.
The unit will show temperature and humidity trends as well as
record maximum and minimum temperature and humidity
readings.

As part of the weather forecasting function, the unit has a built­in barometer that displays atmospheric pressure. Using kinetic­movement graphic illustrations the unit displays atmospheric
pressure trends and displays forecasts as sunny, partly cloudy,
cloudy, rainy and snowy.

Other features of BAA898HG include LCD and key-panel backlight,
rotatable display unit for multi-angle viewing and a Daily
crescendo alarm and Pre-alarm function with an eight-minute
snooze function.

No wire installation is required between the main and remote
units as this unit operates at 433 MHz.

PRE-ALARM FUNCTION FOR

CHANNEL 1 REMOTE SENSOR

The alarm function also has a pre-alarm feature which can alert the
user before the preset alarm time when weather condition changes.

This pre-alarm function applies to Channel 1 Remote Sensor
only.

To enable this function:

1. First activate the alarm function. Then enter the Pre-Alarm
mode by pressing the [
will be displayed.

2. Press and hold the [

The pre-alarm will operate during the selected time interval before
the daily alarm time.

During the pre-alarm operating period, if the temperature recorded
at Channel 1 remote sensor falls to or below 2.0ºC, the pre-alarm
will be triggered. For example, if the daily alarm is set to go off
at 7:00 am and the pre-alarm operating time interval is set to 45

for 2 minutes as that of the daily alarm and the snooze function
will also be activated if the [ SNOOZE / LIGHT ] button or stand­button is pressed.

Note: The daily alarm will NOT function until the next day if the
pre-alarm has been triggered beforehand. Deactivation of the
alarm function will disable the pre-alarm feature automatically.

NOTE ON REMOTE READINGS

received when the remote sensor display is selected, "--- " will be
displayed. To force the main unit to search for remote sensor
signals, press [ MEMORY ] and [ CHANNEL ] simultaneously.

If that fails, check that the remote sensor is still in place. Make
sure the transmission is within range and the path is clear of
obstacles and interference. Repeat this procedure whenever you
find discrepancies between the display on the main unit and the
display on the remote sensor.

CHECKING INDOOR AND REMOTE

TEMPERATURES & HUMIDITIES

To display the indoor and outdoor temperature and humidity
readings, press the [ CHANNEL ] button to toggle among the
indoor, Channel 1, 2 and 3 displays.

The temperature can be shown in Centigrade (°C) or Fahrenheit
(°F). Select the appropriate reading by using the [ °C / °F ] slide
switch (located in the battery compartment). Slide the switch to
°C for Centigrade or °F for Fahrenheit.

If the reading goes above or below the specified amounts, the
display will show a flashing "HHH" or "LLL".

This unit has an auto-scan function that can sequentially display
the indoor and remote readings. To activate this function, press
and hold the [ CHANNEL ] button for 3 seconds. To deactivate
press the [ CHANNEL ] button again.

NOTE ON °C AND °F

The outdoor temperature display on the main unit is dominated
by the selection on the [ °C / °F ] slide switch of the main unit.
Whatever the display unit of the remote sensor is, it will only
apply to the remote sensor itself and the temperature will be
automatically converted to the chosen one of the main unit.

MAXIMUM AND MINIMUM

TEMPERATURES & HUMIDITIES

The maximum and minimum recorded temperatures and
humidities will be automatically stored in memory. To display
them, press [ MEMORY ] . Press [ MEMORY ] again to alternate
between the maximum, minimum and current readings. The
respective MAX or MIN indicator will be displayed.

To clear the memory, press [ MEMORY ] and hold for three
seconds. The maximum and minimum recorded readings will be

erased. Subsequently, if you press [ MEMORY ] after the memory
has been erased, the maximum and minimum readings will have
the same values as the current ones.

TEMPERA TURE & HUMIDITY TREND

The temperature and humidity trend indicator shows the trend of
temperatures and humidities collected at that particular sensor.
Three trends: rising, steady, and falling will be shown.

NOTE:

1. The accuracy of a general pressure-based weather forecast is
about 70% to 75%.

2. The weather forecasts from this unit are predictions that
cover the next 12 to 24 hours. It may not necessarily reflect
the current situation.

HOW TO CHECK

THE BAROMETRIC PRESSURE

The current and historical barometric pressure is shown on the
atmospheric pressure window.

For monitoring the local barometric pressure reading, "0" meter
(preset value) should be selected for the altitude setting. For
monitoring the Sea Level barometric pressure reading at certain
altitude, the local altitude should be selected as the altitude
setting. To set the altitude, press and hold [ HISTORY ] button
to enter the altitude compensation setting mode. Use the [
[ ] button to select from -100 to 2500 meters (whichever
appropriate). Press [ HISTORY ] button to confirm and exit.

The atmospheric pressure can be displayed in mb/hPa or inHg.
The pressure unit is selected on the atmospheric pressure slide
switch inside the battery compartment.

If you want to check the pressure history for a particular hour
during the past 24 hours, press the [ HISTORY ] button. Each
press on the button will go back by an hour. Holding down the
button will increase the value rapidly.
