LONG-RANGE WIRELESS WEATHER STATION WITH IN-OUT THERMO-HYGROMETER AND RF CLOCK
MODEL : BAR898HG USER'S MANUAL

INTRODUCTION

Congratulations on your purchase of the BAR898HG 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. 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. 1
This unit is also a Radio Frequency (RF) controlled clock. It can automatically synchronize its current time and date when it is brought within an approximate 1500-km radius of the radio signal DCF77 generated from Frankfurt, Germany. Other features of BAR898HG 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.

ABOUT RADIO RECEPTION

BAR898HG is designed to automatically synchronize its calendar clock once it is brought within range of the Frankfurt DCF77 radio signal. When the unit is within range, its radio-control mechanism will override all manual settings unless auto-reception of radio signal has been manually deactivated. When the unit is receiving radio signal, the radio reception icon 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 icon will stop blinking. The strength of the reception for the last full hour will be indicated. For better reception, place the unit away from metal objects and electrical appliances to minimize interference. 6
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. Also, this unit is specially designed so that the backlight can be operated differently no matter it is wall-mounted or being put on the table.
Should you wish to deactivate the RF controlled function, press [ MODE ] and [ ] button simultaneously. The radio reception icon will disappear. To reactivate the RF controlled function, press [ MODE ] and [ ] simultaneously and the radio reception icon will be displayed again.

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 2.0C, 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 8
ALARM AND SNOOZE FUNCTION
When the daily alarm goes off, the backlight will be on for five seconds and the alarm-on icon will flash. Initially the active alarm will have a gentle sound. The intensity will increase in three stages. Without interruption, the unit will alarm for 2 minutes. To stop the alarm sound, press any button (expect [ MEMORY ] & [ CHANNEL ] buttons). If the [ SNOOZE / LIGHT ] button or stand-button is pressed, the snooze function will be triggered. The alarm sound will stop and the alarm-on icon will blink for eight minutes. After that the alarm will go off again. To deactivate the SNOOZE function, press the [ ] button.

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 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.
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 REMOTE READINGS

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.

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 9

It may not necessarily reflect the current situation. 3. The "Sunny" icon, as applies to night time, implies clear weather. 10

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. The comfort indicator will appear on the display when the following conditions are satisfied:
Indicator displays on the unit Shows that the Current Environment Ideal range for both relative humidity and temperature Contains excess moisture Contains inadequate moisture
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 [ ] 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.
