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

projection alarm.

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

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4
•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.
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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5
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.
Mounting/Positioning Outdoor sensor

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 6
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.
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
the box has vents.
•Mount the outdoor sensor on the North side to prevent the 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:
•Insert the mounting screw through the front of the outdoor sensor and into the wall.
•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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 7
•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 the 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.
•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.

•Use the Program Menu to switch time formats.
Fahrenheit/Celsius
•Use the SET/°F/°C button to select temperature readings in Fahrenheit or Celsius.
Dashes, HH.H, LL.L 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.
•Batteries may be overpowered or underpowered. Remove batteries from the
projection alarm.
•Press any button 20 times. Leave the projection alarm unpowered for 1-2 hours.
•Install fresh Alkaline batteries with correct polarity.
•If the indoor temperature still shows dashes, HH.H or LL.L, the projection alarm may
need replacement.
Inaccurate Indoor Temperature Reading
Explanation: When the indoor temperature is inaccurate, it is often due to the location of
the display or overpowered/under powered batteries. You can test the accuracy at you
home.
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 temperature should be within 4
degrees to be within tolerance.
•Look for heat sources such as sunlight, door or window frames or reflected heat or
cold near the projection alarm.
Check batteries.
