Striking in gloss black, the RMR382A-BK Oregon Scientific Indoor Outdoor Thermometer with Atomic Clock is compact in size but has a large display and all the features you really need. It displays the indoor temperature plus the outdoor (or other remote) temperature from 1 to 3 locations. It also shows the trends for all indoor and outdoor temperatures. The temperature min/max memory stores the highest and lowest recorded indoor and outdoor values since the last reset, and these can be displayed at the push of a button. Audible high and low temperature alarms can be set for remote Channel 1, and a visible ice warning can be displayed for Channel 1 as well. Rounding out this thermometer's many features is a radio-controlled ("atomic") clock with calendar and daily alarm.

The top line of the LCD panel shows the outdoor (or other remote) temperature and indicates the selected channel in a house icon above which a radio wave icon appears to indicate reception of the remote's signal. A temperature trend arrow (rising, steady, or falling) is shown along with the temperature. If high and/or low temperature alarms are set for Channel 1, alarm bell Hi and Lo icons appear in the display. If the Channel 1 remote temperature falls to between 37°F and 28°F (3°C and -2°C), an ice warning icon in the form of a snowflake or ice crystal above the temperature trend arrow flashes on and off. You can option the display to auto-scan between active sensors, and you can press the MEM button to manually toggle between current, minimum, and maximum temperatures for a selected sensor. Displaying minimum and maximum values for a remote channel also causes minimum and maximum indoor values to be displayed as well.

The second line of the LCD panel shows the indoor temperature and indicates IN for indoor in a house icon. A temperature trend arrow (rising, steady, or falling) is shown along with the temperature. Pressing MEM to view minimum and maximum indoor values also causes minimum and maximum outdoor values for the selected remote channel to be displayed as well.

The third line of the LCD panel shows time and calendar information. The time is shown as hour and minutes in 12-hour format with AM or PM or in 24-hour format. Pressing the MODE button toggles the display between hour and minute with seconds, hour and minute with weekday, or calendar (month, date, and year). Month and date are shown digitally, and you can select MM/DD or DD/MM for their order. The weekday is a two-letter abbreviation in your choice of English, French, German, Italian, or Spanish. If the clock has successfully received the WWVB 60 kHz time-synchronization radio signal from the U.S. atomic clock in Colorado, a tower and waves icon appears to the left of the time. Although you must select your continental U.S. time zone (Pacific, Mountain, Central, or Eastern), the zone is not displayed during normal operation. Also, the year is displayed only during manual setup.

The RMR382A-BK's atomic clock has a single daily crescendo alarm with 2-minute duration. The set alarm time can be viewed as an alternative to the normal time and calendar display. A sound wave ((^.)) icon appears to the left of the hour digit when the alarm time is displayed instead of clock time. An alarm bell icon appears to the left of the hour digit when the alarm is set. A tower and waves icon appears below AM or PM to indicate that the clock is searching for, has received, or has not received the WWVB 60kHz time-synchronization radio signal from the U.S. atomic clock source in Colorado.

One THN132N wireless remote temperature sensor is included with the RMR382A-BK, and the unit can actually monitor up to three sensors at a distance of up to 100 feet (30 meters). The THN132N is a non-displaying sensor. A red LED on the sensor's front panel lights when transmission is occurring. Additional remote sensors can be obtained separately and include the following:

• THGR268. This is a temperature and humidity sensor with its own display. If you use this remote, you won't see the humidity on the RMR382A-BK main unit.
• THGN123N. This is a non-displaying temperature and humidity sensor that, with lithium batteries installed, works down to -40 °C/F.  If you use this remote, you won't see the humidity on the RMR382A-BK main unit.
• THC268. This is a temperature-only sensor with its own display and a waterproof probe on a 10-foot (3-meter) cable for use in pools, spas, hot tubs, freezers, soil, etc.

The RMR382A-BK main unit is designed for free-standing use only and has a non-skid "back foot." The THN132N remote sensor can rest on a horizontal surface, or it can be wall-mounted via a keyhole slot on the back. Please be aware that the small table stand that extends from the back of the remote is an integral part of the battery compartment cover that makes up most of back of the remote. You can hang the remote on a wall with the stand in place. This remote is water-resistant but not waterproof. Choose a mounting location where the THN132N is protected from direct sunlight and direct precipitation.

The main unit uses two AAA alkaline batteries, and the remote temperature sensor uses one AA alkaline battery. All batteries must be obtained separately. If the remote will be used in sub-freezing temperature conditions, a lithium battery is recommended instead of alkaline. Low battery icons are displayed on the main unit for itself and all active remotes when replacement becomes necessary.
