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 built-
in barometer that displays atmospheric pressure. Using kinetic-
movement graphic illustrations the unit displays atmospheric
pressure trends and displays forecasts as sunny, partly cloudy,
cloudy, rainy and snowy.

PRE-ALARMFUNCTIONFOR
CHANNEL1 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 [ ] button twice. The "PRE-AL" icon
will be displayed.
2. Press and hold the [ ] button for 3 seconds to set the
operating time interval for this pre-alarm function. Use the
[ ] or [ ] button to select from the 4 time-intervals: 15, 30,
45 or 60 minutes.
3. Press the [ ] button to confirm and exit. The pre-alarm
function will be enabled automatically which is indicated by
the appearance of the [ ] symbol.
4. To disable this function, press the [ ] button in the Pre-Alarm
mode. The [ ] symbol will disappear and [ - : -- ] will appear
to indicate disable of this function.
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
minutes, the pre-alarm will start to operate at 6:15 am (45 minutes
before 7:00 am). The Pre-Alarm icon will flash and the backlight
will be turned on for 5 seconds. An alarm sound will also go off
for 2 minutes as that of the daily alarm and the snooze function
will also be activated if the [ SNOOZE / LIGHT ] button or stand-
button 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.
NOTEON REMOTEREADINGS
Once batteries are in place in the remote unit, it will start
transmitting samplings at 40-second intervals. If no signals are
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.
CHECKINGINDOOR ANDREMOTE
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.

9
GB
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.
MAXIMUMANDMINIMUM
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.
TEMPERATURE&HUMIDITYTREND
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.
ATMOSPHERICPRESSURE
The atmospheric pressure arrow indicator will indicate if the
atmospheric pressure is increasing, remaining stable, or
decreasing.

WEATHERFORECAST
The unit is capable of detecting atmospheric pressure changes.
Based on collected data, it can predict the weather for the
forthcoming 12 to 24 hours. The effective range covers an area of
30 to 50 km.
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.
3. The "Sunny" icon, as applies to night time, implies clear
weather.
COMFORT LEVELINDICATORS
The comfort level indicators COM, WET or DRY will tell you if the
current environment is comfortable, too wet or too dry.
The comfort indicator will appear on the display when the
following conditions are satisfied:

HOW TO CHECK
THEBAROMETRICPRESSURE
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 [ ] or
[ ] 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.
LOWBATTERYINDICATION
When it is time to replace batteries, the respective low battery
indicator [ ] will show up when the corresponding channel is
selected. The battery level of the main unit is shown on the
Weather Forecast Window when it is running low.
