User manual OREGON SCIENTIFIC JD BAR122HGLA

[. . . ] 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. As part of the weather forecasting function, the unit has a built-in barometer that displays atmospheric pressure. [. . . ] Select the temperature display unit on the °C/°F slide switch. 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. Insert the batteries strictly according to the polarities shown therein. Replace the batteries when the low-battery indicator of the particular 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. 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. 6 Wall-Mount Table-Stand For better reception, place the clock away from metal objects and electrical appliances to minimize interference. To deactivate the snooze function, press the [ALARM] button. To toggle among the 4 U. S. time-zones, press the [ZONE] button. HOW TO SET AND ACTIVATE THE ALARM To set the Alarm Press [ALARM] button to display the daily alarm time (the icon " will be displayed) " Press [ALARM] and hold for three seconds, the value for the hour will flash. 8 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). 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. If the reading goes above or below the specified amounts, the display will show a flashing "HHH" or "LLL". 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. Press [MEMORY] again to alternate between the maximum, minimum and current readings. The respective "MAX" or "MIN" indicator will be displayed. [. . . ] Wall-Mount: Table-Stand: Gently plug in the table stand as shown: MAINTENANCE When handled properly, this unit is engineered to give you years of satisfactory service. If the unit comes in contact with water, dry it immediately with a soft lint-free cloth. Do not clean the unit with alcohol containing detergent, abrasive or corrosive materials. Abrasive cleaning agents may scratch the plastic parts and corrode the electronic circuit. [. . . ]
