GETTING STARTED
BATTERIES
Batteries are supplied with this product:
• Main unit 3 x UM-4 (AAA) 1.5V
• Remote unit 1 x UM-3 (AA) 1.5V
Insert batteries before first use, matching the polarity as
shown in the battery compartment. For best results, install
batteries in the remote sensor before the main unit. Press
RESET after each battery change.
NOTE Do not use rechargeable batteries. Batteries should
not be exposed to excessive heat such as sunshine or fire.

AC ADAPTOR (MAIN UNIT)
The batteries serve as a back-up power supply. For
continuous use, please install the AC adaptor at the base
of the unit.
Make sure the adaptor is not obstructed and the adaptor
socket is easily accessible to the unit.
To be completely disconnected from the power input, the
adaptor should be disconnected from the main unit.
NOTE The main unit and adaptor should not be exposed
to wet conditions. No objects filled with liquid, such as
vases, should be placed on the main unit and adaptor.

REMOTE SENSOR
This product is shipped with RTGN318 / RTGN318D /
RTGN318A Thermo / Hygro Sensor. The main unit can
collect data from up to 6 sensors (5 Thermo / Hygro Sensors
and 1 UV Sensor). (Additional sensors are sold separately.
Visit www.oregonscientific.com for additional sensors.)
The RTGN318 / RTGN318D / RTGN318A Sensor collects
temperature and humidity readings, and signals from official
time-keeping organizations for the radio-controlled clock.
SET UP THERMO / HYGRO SENSOR
1. Open the battery compartment.

2. Insert the batteries.
3. Set the channel and radio signal format (RTGN318D
only). The switches are located in the battery
compartment.
SWITCH OPTION

than one sensor, select a
different channel for each
sensor.

4. Press RESET.
5. Close the battery compartment.
For best results:
• Insert the batteries and select the unit, channel, and
radio signal format before you mount the sensor.
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 70 metres
(230 feet) from the main (indoor) unit.
• 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.
NOTE The transmission range may vary and is subject to
the receiving range of the main unit.
You may need to experiment with various locations to get
the best results.
SENSOR DATA TRANSMISSION
Data is sent from the sensor(s) every 60 Seconds. The
reception icon shown in the Temperature / Humidity Area
indicates the status.
