INTRODUCTION
Congratulations on your purchase of the BAR898HGA Long-
Range Wireless Weather Station with In-Out Thermo-Hygrometer
and RF Clock. 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
328 feet (100 meters).
The BAR898HGA, a weather forecasting device, has several
weather related functions. The main feature is that it takes and
records temperatures and humidities in more than one location.
Using a wireless remote thermo-hygro sensor, it can
simultaneously monitor temperatures and humidities in three
remote locations. The unit will show temperature and humidity
trends as well as record maximum and minimum temperature
and humidity readings. BAR898HGA is able to receive and
display readings from up to 3 remote sensors.
LONG-RANGE WIRELESS WEATHER STATION
WITH IN-OUT THERMO-HYGROMETER AND RF CLOCK
MODEL : BAR898HGA
USER MANUAL
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.
This unit also has a Radio Frequency (RF) controlled clock. It can
automatically synchronize its current time and date when it is
brought within range of the radio signal generated from the U.S.
Atomic Clock.
Other features of BAR898HGA include LCD and key-panel
backlight, rotatable display unit for multi-angle viewing and a
Daily crescendo alarm with an eight-minute snooze function.
No wire installation is required between the main and remote
units as this unit operates at 433 MHz.
However, please note that the Atomic Clock cannot be used
outside the U.S.

NOTES ON OPERATION
For best operation:
1. Insert batteries for the main unit first. Then proceed with
inserting the batteries for the remote unit.
2. Position the remote unit and the main unit within effective
transmission range. In usual circumstances, the effective range
is up to 328 feet (100 meters).
3. Though the remote unit is weather resistant, it should be
placed away from direct sunlight, rain or snow.
BATTERY INSTALLATION: MAIN UNIT
1. Gently open the battery compartment door as shown.
2. Insert four (4) pieces of UM-3 or "AA" size batteries in
accordance with the polarities shown.
3. Close the battery compartment door.

BATTERY AND CHANNEL INSTALLATION:
REMOTE UNIT
The remote thermo-hygro sensor unit uses two (2) UM-3 or
“AA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
2. Select the channel number on the CHANNEL slide switch.
3. Select the temperature display unit on the °C/°F slide switch.
4. Insert the batteries strictly according to the polarities shown
therein.
5. Replace the battery compartment door and secure its screws.
Replace the batteries when the low-battery indicator of the par-
ticular channel lights up on the main unit.
Note: Once a channel is assigned to a remote unit, you can only
change it by removing the batteries or resetting the unit.
Standard Alkaline batteries contain signifcant amounts of water.
Because of this they will freeze in low temperatures of
approximately 10°F (-12°C). Disposable Lithium batteries have
a much lower threshold for temperature with an estimated freezing
range of below -40°F (-40°C). The Liquid Crystal Display in
outdoor thermometers will remain operational to -20°F (-28°C)
with adequate power.
Wireless ranges can be impacted by a variety of factors such as
extremely cold temperatures. Extreme cold may temporarily reduce
the effective range between the sensor and the base station. If the
unit's performance fails due to low temperature, the unit will
resume proper functioning as the temperature rises to within the
normal temperature range (i.e no permanent damage will occur
to the unit due to low temperatures).
LCD AND KEY-PANEL BACKLIGHT
For easy viewing in the dark this unit is featured with backlight
function on the LCD display as well as on the front key-panel.
The unit is designed such that you can conveniently use the
backlight feature irrespective of whether the unit is wall-mounted
or free standing on the table.

Wall-Mount Table-Stand
Press the corresponding [ SNOOZE / LIGHT ] button or the
button on the stand. The backlight will be activated for 5 seconds.
ABOUT RADIO RECEPTION
The BAR898HGA is designed to automatically synchronize its
calendar clock once it is brought within range of the U.S. Atomic
Clock radio signal.
When the BAR898HGA is within range, its radio-control mecha-
nism will override all manual settings unless the auto-reception
function is manually disabled.
When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes
about 2 to 10 minutes, depending on the strength of the radio
signal.
When the reception is complete, the RADIO RECEPTION signal
will stop blinking. The strength of the reception for the last full
hour will be indicated.

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.
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.
If the reading goes above or below the specified amounts, the
display will show a flashing “HHH” or “LLL”.
NOTE ON REMOTE READINGS
Once batteries are in place in the remote unit, it will start trans-
mitting samplings at 40-second intervals.
If no signals are received when the remote sensor display is
selected, “ ” will be displayed. To initiate the main unit
search for remote sensor signals, press [MEMORY] and
[CHANNEL] simultaneously.
If that fails, check if 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.
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.

GB
TEMPERATURE & 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.
ATMOSPHERIC PRESSURE
The atmospheric pressure arrow indicator will indicate if the
atmospheric pressure is increasing, remaining stable, or decreasing.
WEATHER FORECAST
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 19 to 31 miles (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 LEVEL INDICATORS
The comfort level indicators COM, WET or DRY will tell you if
the current environment is comfortable, too wet or too dry.
