Batteries

Explanation: Many problems are resolved with fresh batteries of the appropriate voltage.

Many items sent in under warranty work, when tested with fresh batteries. Batteries

manufactured this year will have an expiration date 10 years (or more) in the future. Battery

technology has improved, and batteries will maintain voltage longer in storage. However,

the environment the batteries reside in for the 10 years can deplete the power.

•We suggest name brand Alkaline batteries for indoor displays.

•A minimum voltage of 1.48V for each battery is necessary for proper performance.

•Use batteries dated at least six years in advance of the current year. Batteries dated

earlier than six years from now may still work but may be unstable in performance.

•Good name brand batteries make less noise, which reduces the chance of RF (radio

frequency) interference from the battery compartment.

Digital Clock Factory Restart

Explanation: The factory restart returns the clock and outdoor sensor to an “out-of-the-

box” default state and often resolves an issue.

Factory Restart:

1. Remove all power from outdoor sensor and clock.

2. Press one of the buttons on the clock at least 20 times to clear all memory.

3. Verify that the clock is blank before proceeding (there may be lines painted on the

screen that will show when there is no power).

4. Leave both units without power for 15 minutes (very important).

5. Insert fresh batteries into the outdoor sensor, then into the clock.

6. Keep the outdoor sensor 5-10 feet from the clock.

7. When RF connection is established, the temperature/humidity will appear on the

station. Allow the outdoor sensor and clock to sit together for 15 minutes to establish a

strong connection.

8. Do not press buttons for 15 minutes.

•For optimum 433MHz transmission, place the outdoor sensor no more than 330 feet

(100 meters, open air) from the clock.

•See the section on mounting and distance/resistance/interference for details on

mounting the outdoor sensor.

Compatible Outdoor sensors

•The TX191TH Outdoor sensor comes packaged with this atomic clock.

•The TX191TH (433MHz) Outdoor sensor is compatible with this atomic clock.

Power Requirements

•2-AA batteries power the Outdoor sensor.

•2-AA batteries power the clock.

•We recommend Alkaline batteries for the Outdoor sensor.

La Crosse Technology, Ltd Page 3

Quick Connect

Explanation: If sensor loses connection to the clock for any reason, the clock will show

NO in the outdoor temperature area after 30 minutes. The clock will search for 3 minutes

every hour to reconnect with sensor.

•Hold the PLUS (+) button 2 seconds to search for the outdoor sensor.

Dashes show for Outdoor Temperature

Explanation: Dashes mean the connection is lost between the atomic clock and the

Outdoor sensor.

•Batteries often resolve the connection.

•Distance/Resistance can cause loss of connection between the Outdoor sensor and

the atomic clock.

•Turn the atomic clock 90 degrees towards the Outdoor sensor to provide better

reception. This allows more antenna surface to face the Outdoor sensor signal.

•Try the quick connect or factory restart.

Inaccurate Outdoor Temperature Reading

Explanation: High Outdoor temperature readings are generally a location issue. Low

Outdoor temperature readings are power related or a sensor going bad.

•The Outdoor sensor reads the environment where it is mounted. When mounted inside

the home, it will read inside temperature.

•When the Outdoor sensor reads high during the day, but not at night, it is a positioning

problem.

•Look for heat sources such as sunlight, door or window frames or reflected heat.

Side-by-side test: Place the Outdoor sensor right next to the atomic clock for 2 hours.

•Compare indoor and Outdoor temperature. The temperatures should be within 4

degrees to be within tolerance.

•If the Outdoor sensor reads correctly when next to the atomic clock, try a different

location outside.

Intermittent Outdoor Temperature

Explanation: Intermittent problems are the hardest to resolve. RF (radio frequency)

communication may come and go occasionally. This can be normal in some environments

(e.g. moister climates). If Outdoor sensor signal is lost, please wait 2-4 hours for the signal

to reconnect on its own.

•Move the Outdoor sensor to a closer location.

•Distance/Resistance can cause loss of Outdoor sensor signal.

•Check Batteries.

La Crosse Technology, Ltd Page 4

Freezer test: Confirm the atomic clock is reading the correct Outdoor sensor (not a

neighbor’s sensor). Place the Outdoor sensor in the freezer for an hour and watch the

temperature drop on the atomic clock.

Indoor distance test: Please complete the Restart with Outdoor sensor and atomic clock

5-10 feet apart and inside to establish a strong connection.

•After 15 minutes, if there is a reading in the Outdoor temperature area, move the

Outdoor sensor to another room with one wall between the Outdoor sensor and the

atomic clock.

•Observe to see if the temperature remains on consistently for 1 hour.

•If the temperature remains on while in the house, then it is likely a distance/resistance

issue.

•Move the Outdoor sensor to different locations outside to find a location where the

temperature reading will hold.

Outdoor Temperature is stuck or HH.H, LL.L

Explanation: These symbols are error messages indicating the Outdoor sensor is outside

of its readable range.

•Check Batteries.Overpowered or underpowered batteries can cause this reading.

•Replace Outdoor sensor.

Outdoor sensor drains batteries quickly

•Test a new set of alkaline batteries. Write down the date of installation and the voltage

of the batteries.

•When the batteries fail, please note the date and voltage again.

•Check the distance and resistance between the Outdoor sensor and atomic clock.

Outdoor sensors at the end of the range may work while batteries are fresh but not

after they drain a bit.

•Check for leaking batteries, which may damage the Outdoor sensor.

•Battery life is over 18 months when using reputable battery brands.

Outdoor sensor fell. The sensor no longer works

Explanation: If there is no physical damage to the Outdoor sensor, the fall may not have

caused internal damage. A fall can shock the Outdoor sensor or the batteries in the

Outdoor sensor. Batteries that have fallen on a hard surface may be damaged and unable

to function properly.

•Complete a Restart with fresh batteries.

•Use Batteries dated at least six years in advance of the current year. Batteries dated

earlier than six years from now may still work but may be unstable in performance.

Note: A Outdoor sensor that has fallen into puddle, snow, or other standing water, will

likely have water damage and need to be replaced. Outdoor sensors are water resistant,

not waterproof.

La Crosse Technology, Ltd Page 5

Mounting/Positioning Outdoor sensor

First: Place the Outdoor sensor in the desired shaded location and the atomic clock in the

home. Wait approximately 1 hour before permanently mounting the Outdoor sensor to

ensure that there is proper reception.

POSITION

Outdoor:

•Protect the Outdoor sensor from standing rain or snow and from the overhead sun,

which can cause it to read incorrectly.

•Mounting under an eave or deck rail works well.

•If you choose, you can construct a small roof or box for the Outdoor sensor. Be sure a

box has vents.

•Mount the Outdoor sensor on the North side where to prevent sun from causing

incorrect readings.

•Mount at least 6 feet in the air for a strong RF (radio frequency) signal.

•Do not mount the Outdoor sensor on a metal fence. This significantly reduces the

effective range.

•Outdoor sensors are water resistant, not waterproof.

Indoor or Outdoor:

•Mount Outdoor temperature sensor vertically.

•Avoid more than one wall between the Outdoor sensor and the atomic clock.

•The maximum transmitting range in open air is over 200 feet (60 meters).

•Obstacles such as walls, windows, stucco, concrete and large metal objects can

reduce the range.

•Do not mount near electrical wires, transmitting antennas or other items that will

interfere with the signal.

•RF (radio frequency) signals do not travel well through moisture or dirt.

MOUNT

Option 1:

•Install one mounting screw (not included) into a wall.

•Place the Outdoor sensor onto the screw (hanging hole on the backside).

•Gently pull down to lock the screw in place.

Option 2:

•Insert the mounting screw through the front of the Outdoor sensor and into the wall.

•Tighten the screw to snug (do not over tighten).

Fahrenheit/Celsius

•Use the program menu to switch from Fahrenheit to Celsius.

Supported Time Zones

•This clock has 7 Time Zones: AST=Atlantic, EST= Eastern, CST= Central,

La Crosse Technology, Ltd Page 6

MST= Mountain, PST= Pacific, AKT= Alaska, HAT=Hawaiian The digital clock works in

North America.

•Outside of North America, the digital clock will not receive a WWVB signal, but will

keep time like a quartz clock.

Dashes, HHH, LLL or Stuck Indoor Temperature

Explanation: These symbols are error messages indication the indoor sensor is outside of

its readable range. For indoor readings, this is generally a power related issue.

•This is generally a power related issue.

•Batteries may be overpowered or underpowered. Remove batteries from atomic digital

clock.

•Press any button 20 times. Leave the digital clock unpowered for 1-2 hours.

•Insert fresh alkaline batteries with correct polarity.

•If the indoor temperature is still dashes or HHH, LLL, the digital clock may need

replacement.

Does the clock have a backlight?

•No, as this clock is battery operated there is no backlight.

Time is off by hours

•Check to see if the WWVB Tower icon appears on the atomic digital clock. If not, the

digital clock has not received a WWVB time signal in the past 24 hours.

•Reposition the digital clock with the front or back facing Colorado.

•Check that the Time Zone selected correctly reflects your location. Adjust the time

zone in the Program Menu.

•Check that the DST indicator is correct for your location (most areas observe DST so

this should be ON). Adjust the DST indicator in the Program Menu.

•Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or

radio equipment make it difficult to receive the WWVB time signal.

Daylight Saving Time

Some states are considering going to year around Daylight Saving Time. We have built in

options to accommodate this feature into the program menu.

DST ON: (Automatically gain 1 hour in spring, lose 1 hour in fall)

DST OFF: (Remain in Standard Time all year long)

DST ALWAYS ON: (Remain in Daylight Saving Time all year long)

•Dependent on your location, position of the clock in your home, and atmospheric

interference, it may take up to 5 nights for the change from Daylight Savings Time to

Standard Time and vice-versa to occur.

•Check for a WWVB Tower Icon showing on the atomic digital clock. The tower icon

indicates you have received the WWVB signal from Ft Collins CO in the past 24 hours.

•Check that the clock is in the correct Time Zone.

La Crosse Technology, Ltd Page 7

•Check whether the DST indicator is ON, OFF or ALWAYS ON. If the indicator is OFF or

ON the clock will not change seasonally.

•Check for fresh batteries. Without proper batteries, the antenna will have a harder

time picking up the signal.

•Position the digital clock in a window (with the front or back) facing Ft. Collins, Colorado

and leave for up to five nights. If you do not have a window facing this direction,

position the clock near an outside wall and point the unit in this general direction.
