INTRODUCTION

Thank you for selecting this Oregon Scientific

Wireless

Weather Station with Temperature / Humidity Display and
Self-Setting Atomic Clock (BAR388HGA). This clock is
supplied with a remote sensor (THGR122N) and can
support up to 3 sensors in total (additional sensors sold
separately).

NOTE Please keep this manual handy as you use your new
product. It contains practical step-by-step instructions, as
well as technical specifications and warnings you should
know about.

GETTING STARTED

BATTERIES

Insert batteries before first use, matching the polarity (+
and -). Press RESET after each battery change.

SENSOR DATA TRANSMISSION

indicates main unit batteries are low.

NOTE Do not use rechargeable batteries. We recommend
that you use alkaline batteries with this product for longer
usage and lithium batteries in temperatures below
freezing.

REMOTE SENSOR

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.

To set up the sensor:
1. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).

3. Select a channel. Make sure you use a different channel

for each sensor.

4. Place the sensor near the main unit. Press RESET on

the sensor.

5. Simultaneously press CHANNEL and MEM on the main

unit to initiate signal sending between the sensor and
main unit.

6. Close the battery door and secure the screws.
7. Place the sensor in the desired location using the table

stand or wall mount.

For best results:
• 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.

• 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.

The sensor reception icon in the remote sensor area
shows the status.

The sensor cannot be found.
Search for the sensor or check
batteries

To search for a sensor:
Simultaneously, press and hold MEM and CHANNEL for
2 seconds.

NOTE If the sensor is still not found, check the batteries,
obstructions, and remote unit location.

CLOCK

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 Fort Collins, Colorado.

The clock collects the radio signals whenever it is within

3219 km (2000 miles) of a signal.

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.

RECEPTION SIGNAL

To enable and force a signal search:
Press and hold for 2 seconds.

To disable the signal reception:
Press and hold for 2 seconds.

STRONG SIGNAL WEAK SIGNAL NO SIGNAL

SET CLOCK

If the clock signal reception is enabled and a signal is being

received the clock does not need to be manually set.

1. Press and hold MODE for 2 seconds.

2. Press or to change the settings.

3. Press MODE to confirm.

4. The settings order is: US time zone (Pacific (P), Eastern

(E), Central (C) and Mountain (M)) offest, hour, minute,

year, month, day and language.

NOTE The language options are English (E), German (D),

French (F), Italian (I), and Spanish (S).

Press MODE to choose between the clock with seconds
and clock with weekday display modes.

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 -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).
