GREAT BUY I just love this indoor/outdoor thermometer. I live along the Adirondack Parkway in NY and temperature change daily.

Performs as expected Works great. I assume the temperature is accurate, although I have never verified it. Out of the box, did not work I spent half hour (not counting opening the package it was packed it) trying to get the time set. No luck. GREAT PRODUCT!! I LOVE THE FACT THAT THEY HAVE A SCREW WITH A KIND OF A HANDLE WIRE THING THAT HOLDS THE THING THAT TELLS YOU THE TEMP OUTSIDE....

This product is shipped with a THGR122NX Thermo / Hygro Sensor that collects Temperature and Humidity data. Data can be collected from up to 3 sensors. Additional sensors sold separately.
The clock automatically synchronizes the current time and date when it is brought within range of the WWVB-60 atomic clock signal generated from Fort Collins, Colorado. For more information, please visit:>radioclocks.htm NOTE The signals are collected by the main unit when it is within 1500 km (932 miles) of a signal. Initial reception takes 2-10 minutes, and is initiated when you first set up the unit, and whenever you press RESET. If the RF signal is weak, it can take up to 24 hours to get a valid RF signal reception. Once complete, the reception icon will stop blinking. The icon is shown in the Clock Area.
Wireless Weather Forecaster with Temperature and Humidity Model: BAR638HGA


Thank you for selecting the Oregon Scientific Wireless Weather Forecaster with Temperature and Humidity (BAR638HGA). This device bundles precise time keeping, weather forecast, and indoor and outdoor temperature and humidity monitoring features into a single tool you can use from the convenience of your home. 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.
SET UP SENSOR 1. Open the remote sensor battery compartment with a small Phillips screwdriver. 2. Insert the batteries, matching the polarity (+ and -) as shown in the battery compartment.
STRONG SIGNAL 1. LCD display 2. LED status indicator


To force a manual search for clock signals, press and hold for 2 seconds. If no signal is found, check the batteries. SWITCH OPTION Channel Channel 1-3. If you are using more than one sensor, select a different channel for each sensor.


TIME ZONES When the main unit receives an atomic clock signal for the first time, or when you force a manual search for the atomic clock reception, the time will automatically be set to Pacific time (PA). To change to another time zone (MO - Mountain, CE - Central or EA - Eastern) simply: 1. Press and hold MODE for 2 seconds. 2. Press or to change the setting. 3. Press to confirm and exit setting mode.

3. Set the channel. The switch is located in the battery compartment. 4. Place the sensor near the main unit. Press RESET on the sensor. Then, press and hold MEM and CHANNEL on the main unit to initiate signal sending between the sensor and the main unit. The reception icon on the main unit will blink for approximately 3 minutes while it is searching for the sensor. (Refer to the "Data Transmission" section for more information.) 5. Close the remote sensor battery compartment. 6. Secure the sensor in the desired location using the wall mount or table stand.
TURN ATOMIC CLOCK ON / OFF Perform this step if you cannot receive atomic clock signals. Press and hold for 2 seconds. Then, manually set the clock following the Set Clock instructions (below). The signal icon indicates that the clock feature is ON. No icon means that it is OFF.

SET CLOCK / CALENDAR You only need to do this if you have disabled the atomic clock feature (for example, if you are too far from or cannot receive a signal). 1. Press and hold MODE for 2 seconds. The Clock Area will blink. 2. Select the time zone, hour, minute, year, month, day, and day of the week language. Press or to change the setting. 3. Press MODE to confirm. The time zone options are PA (Pacific), MO (Mountain), CE (Central) and EA (Eastern). The language options are (E) English, (F) French, (D) German, (I) Italian, and (S) Spanish.
Insert batteries before first use, matching the polarity (+ and -) 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. shows when batteries are low. For best results: Insert the batteries and select the channel before you mount the sensor. Place the sensor out of direct sunlight and moisture. Do not place the sensor more than 98 feet (30 meters) 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. Standard Alkaline batteries contain significant amounts of water. Because of this they will freeze in low temperatures of approximately 10F (-12C). Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -40F (-40C). 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 Liquid Crystal Display in outdoor thermometers will remain operational to -20F (-7C) with adequate power. You may need to experiment with various locations to get the best results. CHANGE SETTINGS To change, time, calendar and language settings: 1. Press and hold MODE for 2 seconds to enter setting mode. 2. Press or to change settings. (To reach the setting you want quickly, press and hold or.) 3. Press MODE to confirm. DATA TRANSMISSION Data is sent from the sensor(s) every 40 seconds. The reception icon shown in the Temperature and Humidity Areas show the status.


NOTE It is recommended that you use alkaline batteries with this product for longer performance.
