Place the sensor in a location with a clear view to  
the sky, away from metallic or electronic objects.  
Position the sensor close to the main unit during  
cold winter months as below-freezing temperatures  
may affect battery performance and signal  
transmission.

USER MANUAL  
INTRODUCTION  
Thank you for selecting the Oregon ScientificTM Wireless  
Indoor / Outdoor Thermometer with Self-Setting Atomic  
Clock (RMR682A). The main unit can support up to 3  
sensors. To purchase additional sensors, please contact  
your local retailer.

The transmission range may vary depending on many  
factors. You may need to experiment with various locations  
to get the best results.

Standard Alkaline batteries contain significant amounts of  
water. Because of this they will freeze in low temperatures  
of approximately -12°C (10°F). Disposable Lithium batteries  
have a much lower threshold for temperature with an  
estimated freezing range of below -40°C (-40°F).

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).

The sensor collects temperature readings approx. every  
40 seconds and sends them to the main unit. The main  
unit can collect data from up to 3 sensors.  
NOTE If the sensor is still not found, check the batteries,

Remove the screws from the battery door.  
Insert the batteries, matching the polarity (+ / -).  
This product is designed to synchronize its date and time  
automatically once it is within range of the WWVB-60  
signal from the atomic clock in Boulder, Colorado.  
18. Time, alarm and date  
The sensor collects the radio signals whenever it is within  
1500 km (932 miles) of a signal.  
BACK VIEW  
NOTE Initial reception takes 2-10 minutes for first set up or  
when RESET is pressed. Once complete, the reception icon  
will stop blinking. If the signal is weak, it can take up to 24  
hours to get a valid signal.
