Projection Alarm Factory Restart

Explanation: The factory restart returns the projection alarm and outdoor sensor to an “out-of-the-box”

state and often resolves an issue.

Factory Restart:

1. Remove all power (batteries and AC) from outdoor sensor and projection alarm.

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

3. Verify that the projection alarm is blank before proceeding (some lines are painted on the screen and

will show with batteries out).

4. Leave unpowered for 15 minutes (very important).

5. Insert the AC cord into the wall outlet then into the projection alarm.

6. Insert fresh batteries into the outdoor sensor.

7. Press the TX button on the outdoor sensor to transmit RF signal.

8. Keep the outdoor sensor 5-10 feet from the projection alarm.

9. When RF connection is established, the temperature will appear on the station. Allow the outdoor

sensor and projection alarm to sit together for 15 minutes to establish a strong connection.

10. 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 projection alarm.

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

sensor.

Outdoor Temperature Sensor

Compatible Outdoor Sensors

The TX141-B3, TX141-B or TX141 outdoor sensor comes packaged with this projection alarm. These

sensors are not interchangeable. Be sure to check the model before ordering.

The TX141B (all versions),and TX141-A (433MHz) outdoor sensors are compatible with the

projection alarm sold with the TX141-Bv2 sensor.

Quick Connect

Explanation: The quick connect is used for a projection alarm and outdoor sensor that have been

working but lost connection due to interference or low batteries. This is not a thorough factory reset.

1. Bring the outdoor sensor and projection alarm together inside and place the units 5-10 feet apart

with nothing between them.

2. Hold the +/TEMP button on the projection alarm. The outdoor temperature area will flash.

3. Remove battery cover from the outdoor sensor and press and release the TX button to send the

signal.

4. Wait for 2 minutes for the outdoor temperature to appear on the projection alarm.

Factory Restart: If the above procedure does not work, please try the factory reset.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 3

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.

Use Alkaline or Lithium batteries in the outdoor sensors.

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.

Power Requirements

2-AA batteries power the outdoor sensor.

We recommend Alkaline batteries for the outdoor sensor.

You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.

Dashes show for Outdoor Temperature

Explanation: Dashes mean the connection is lost between the projection alarm and the outdoor sensor.

Batteries often resolve the connection.

Distance/Resistance can cause loss of connection between the outdoor sensor and the projection

alarm.

Turn the projection alarm 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 sensors 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: Bring the outdoor sensor in the house and place it next to the projection alarm 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 projection alarm, 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. www.lacrossetechnology.com/support Page 4

Freezer test: Confirm the projection alarm is reading the correct outdoor sensor. Place the outdoor

sensor in the freezer for an hour and watch the temperature drop on the projection alarm.

Indoor distance test: Please complete the Restart with outdoor sensor and projection alarm 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 projection alarm.

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 indication the outdoor sensor is outside of its readable

range.

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

Replace outdoor sensor.

Note: The last outdoor reading may remain (not change) for several hours when connection is lost. The

outdoor temperature reading will flash when the connection is first lost or intermittent.

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 projection alarm. 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 24 months when using reputable battery brands for both Alkaline and Lithium

batteries.

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: An outdoor sensor that has fallen into puddle, snow, or other standing water, will likely have water

damage and needs to be replaced. Outdoor sensors are water resistant, not waterproof.

Replacement Outdoor Sensors

Mounting/Positioning Outdoor sensor

First: Place the outdoor sensor in the desired shaded location and the projection alarm in the home. Wait

approximately 1 hour before permanently mounting the outdoor sensor to ensure that there is proper

reception.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5

POSITION

Mount outdoor temperature outdoor sensors vertically.

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.

Outdoor sensors are water resistant, not waterproof.

Avoid more than one wall between the outdoor sensor and the projection alarm.

The maximum transmitting range in open air is over 330 feet (100 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.

Do not mount the outdoor sensor on a metal fence. This significantly reduces the effective range.

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:

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

Position Projection Alarm

The projection alarm has a wide base to sit on a desk or table.

Place within range of the outdoor sensor.

The maximum transmitting range in open air is 330 feet (100 meters).

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce the range.

Choose a location 6 feet or more from electronics such as cordless phones, wireless gaming

systems, televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.

Be aware of electrical wires and plumbing within a wall. This will interfere with RF (radio frequency)

signal reception.

Distance/Resistance/Interference

Distance:

The maximum transmitting range in open air is over 330 feet (100 meters) between the outdoor

sensor and the projection alarm. This range is in open air with ideal conditions.

Consider what is in the signal path between the projection alarm and the outdoor sensor.

Avoid placing electronic in the signal path between the projection alarm and the outdoor sensor.

Resistance:

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce the range.

When considering the distance between the outdoor sensor and the projection alarm (330 feet open

air), cut that distance in half for each wall, window, tree, bush or other obstruction in the signal path.

Closer is better.

Windows reflect the RF (radio frequency) signal.

Metal absorbs the signal and reduces the range.

Stucco has a metal mesh that absorbs the signal.

Do not mount the outdoor sensor on a metal fence. This significantly reduces the effective range.

Interference:

Consider items in the signal path between the outdoor sensor and the projection alarm.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 6

Sometimes a simple relocation of the outdoor sensor or the projection alarm will correct the

interference.

Windows can reflect the radio signal.

Metal will absorb the RF (radio frequency) signal.

Stucco has a metal mesh that absorbs signal.

Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports, military bases, etc.)

Electrical wires (utilities, cable, etc.)

Vegetation is full of moisture and reduces signal.

It is difficult for RF (radio frequency) signal to travel through a hill.

The Atomic Projection Alarm has not received a WWVB time signal in the past 24-hours.

Position the Atomic Projection Alarm for better reception.

Hold the -/TIME button to send the Atomic Projection Alarm on a signal search at night.

Allow up to 5 nights to receive the time signal.

Moon Phase

The eight phases of the moon shown below are determined by the year, month, and date set on the

Atomic Projection Alarm.

Note: With the moon shown against a light colored background, the phases will show opposite to a paper

calendar. The segments that are highlighted portray the part of the moon that is lit. For instance, the

moon will be blank during a new moon and dark during a full moon.

New Moon occurs when the moon is between the earth and sun so the illuminated portion of the

moon is on the backside facing the sun and we cannot see it. After a new moon, the illuminated

portion will increase or wax until the full moon occurs.

Full Moon occurs when the earth, moon, and sun are in approximate alignment, with the moon and

the sun on opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us

complete visibility of one side of the entire moon. After a full moon, the illuminated portion will

decrease or wane until the new moon occurs.

First Quarter and Last Quarter moons occur when the moon is at a 90-degree angle to the earth

and sun. Therefore, we see half of the moon illuminated and half is in shadow.

Waxing means growing or expanding illumination and happens after a new moon.

Waning means decreasing illumination and occurs after a full moon.

Crescent refers to the moon being less than half-illuminated. Crescents can be waning or waxing.

Gibbous describes a moon phase when more than half is illuminated. Gibbous can be waxing or

waning.

Backlight: Projection Alarm with TX141-Bv2 sensor

The backlight will come on for 5 seconds when the SNOOZE/LIGHT button is pressed.

The backlight does not stay on permanently.
