USER MANUAL
INTRODUCTION
For best results:
Clock / Alarm area:
•
•
Place the sensor out of direct sunlight and moisture.
Do not place the sensor more than 30 m (100 ft) from the
main (indoor) unit.
Thank you for selecting this Oregon ScientificTM Wireless
Indoor / Outdoor Thermometer with Indoor Humidity and
Self-Setting Atomic clock (RMR683HGA). This clock is
supplied with a remote sensor (THN132N) and can support up
to 3 sensors in total (additional sensors sold separately).
�
�
•
Position the sensor so that it faces the main (indoor)
unit, minimizing obstructions such as doors, walls, and
furniture.
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.

CLOCK OVERVIEW
FRONT VIEW
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 -30°C (-22°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).

GETTING STARTED
CLOCK
SETTING UP THE CLOCK
Insert batteries before first use, matching the polarity
(+ and -). RESET after each battery change.
CLOCK RECEPTION
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.
�
The clock collects the radio signals whenever it is within 1500
km (932 miles) of a signal.
1. TEMP/ HUMIDITYHI / LO : Change settings or enable
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.
