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
100 meters.
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.
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.
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.
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.
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.
