Oregon Scientific BAR938HG - Cable Free Weather Station Manual

INTRODUCTION

BAR938HG is an all-in-one clock and weather device. RF- controlled, it can automatically synchronize its current time and date when it is brought within an approximate 1500km radius of the radio signal generated from Frankfurt, Germany (DCF77).
BAR938HG does weather forecasts with kinetic-movement graphic illustrations and tells indoor and outdoor temperature. It also shows the trend of changes plus the recorded maximum and minimum temperatures.
Apart from temperature, BAR938HG shows the indoor and outdoor relative humidity and rates the comfort level. It also retains the maximum and minimum relative humidity readings. A remote thermo-hygro sensor is included with the unit. BAR938HG is able to receive and display readings from up to 3 remote sensors.
The built-in barometer enables BAR938HG to display the atmospheric pressure with user-selectable altitude adjustment. A bar graph will show the pressure trend of the last 24 hours.
What is more, BAR938HG is equipped with a moon phase scanner, which lets you check the moon phase of any day between 1990 and 2089.
Other features include a HiGlo backlight, daily crescendo alarm with eight-minute snooze function, and extra-large display.
No wire installation is required between the main and remote units. As BAR938HG operates at 433MHz, it can be used in the U.S. and most places in Continental Europe.

ABOUT RADIO RECEPTION

BAR938HG is designed to automatically synchronize its calendar clock once it is brought within range of the Frankfurt DCF77 radio signal. It will scan and adjust every full hour.
When BAR938HG is within range, its radio-control mechanism will override all manual settings.
When the unit is receiving a radio signal, the RADIO RECEPTION indication will start to blink. A complete reception generally takes about two to 10 minutes, depending on the strength of the radio signal. If the radio signal is weak, it can take up to 24 hours to get a valid signal reception.
When the reception is complete, the RADIO RECEPTION indication will stop blinking. If the signal is received, a RADIO RECEPTION indication [] will be shown. Otherwise, [] is displayed.
For better reception, place the clock away from metal objects and electrical appliances to minimize interference.
Should you wish to deactivate the RF controlled function, press MODE and DOWN button simultaneously.
To reactivate the RF control function, from its deactivated status press MODE and UP simultaneously.

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. 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 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.

HOW TO CHECK INDOOR AND OUTDOORREMOTE TEMPERATURES & HUMIDITIES

To display indoor temperatures and humidities, press the CHANNEL button until the [] indicator lights up.
To display outdoor-remote temperatures and humidities, press the CHANNEL button to scroll through the readings from up to 3 remote sensors.
The temperature can be shown in Centigrade (°C) or Fahrenheit (°F). It is selected on the °C/°F slide switch. Slide the switch to °C for Centigrade or °F for Fahrenheit.
If the readings go above or below the specified range, the display will show flashing "HHH" or "LLL".

CHANNEL SCAN FUNCTION

Press and hold CHANNEL button for 3 seconds to enter channel scan function. The readings of each channel will be displayed one by one for 4 seconds automatically. Press any key to stop the scan function.

NOTE ON REMOTE TEMPERATURE & HUMIDITY

Once batteries are in place for the remote unit, it will start transmitting samplings at 39-43-second intervals.
If no signals are received when the remote temperature and humidity is selected, blanks will be displayed. Press and hold the CHANNEL button to enforce a search. This is useful in synchronizing the transmission and reception of the remote and main units.
If that fails, check if the remote unit is still in place. Make sure the transmission is within range and path is clear of obstacles and interference.
