and manual set time.

SETUP INSTRUCTIONS STEP BY STEP

STEP 1:

Remove battery cover from the Wireless

Thermometer.

Insert 2 NEW AA batteries (not included) into

the back of the Wireless Thermometer.
Observe the correct polarity (see marking
inside the battery compartment).

The Wireless Thermometer will light up and

show, indoor temperature, and time (12:00).

STEP 2:

Ensure that the transmitter is within 10 feet of the

Wireless Thermometer.

Remove battery cover from TX141-B transmitter:

Slide the battery cover down and lift off the front.

Insert 2 NEW AA batteries into the transmitter.

Observe the correct polarity.

Within 3 minutes the Wireless Thermometer will show

readings in the outdoor temperature area on the LCD.

Note: Allow the Wireless Thermometer and the

transmitter to stay within 10 feet of each other for the first 15
minutes of set up.

Do Not Mix Old and New Batteries

Do Not Mix Alkaline, Standard, Lithium or Rechargeable

Batteries

TRANSMITTER SIGNAL STRENGTH INDICATOR

 After the batteries are inserted, the Wireless Thermometer will

search for the outdoor temperature transmitter for 3 minutes.

 The antenna symbol will flash during reception, and

temperature display will be dashes “---“.

 No antenna symbol will show during RF (radio frequency)

synchronization.

 If synchronization fails once, the antenna will lose one bar.
 If synchronization fails twice, the antenna will lose two bars.

 If RF (radio frequency) reception fails five times, the antenna

symbol will be shown as .

 The antenna will show full display with successful

RF (radio frequency) reception.

TROUBLE SHOOTING

If the Wireless Thermometer does not display the outdoor

temperature after 3 minutes, remove the batteries from both units
and start the setup process again.

If the outdoor temperature does not show up after a second

attempt, please slide open the battery cover of the outdoor
transmitter to reveal the TX button. Push down on the TX button
for 3 seconds to send a wireless signal to the Wireless
Thermometer.

For optimal 433 MHz signal reception, the outdoor transmitter

should be placed within 200 feet (60 meters) from the indoor
Wireless Thermometer.

Note: Use Alkaline batteries

(or Lithium for temperatures below -28.8°C / -20°F).

SET TIME

readout.

MAXIMUM/MINIMUM TEMPERATURE READINGS

The Wireless Thermometer: will show the daily minimum and
maximum temperatures each day starting at midnight (12:00 AM).
The temperature station automatically resets the min/max
temperatures at midnight (12:00 AM).

VIEW MINIMUM: Press MAX/MIN button to show the minimum
temperature record.
RESET MINIMUM: With the minimum temperatures displayed,
press and hold the MAX/MIN key for 2 seconds to manually clear the
MIN records in memory.

TEMPERATURE TREND ICONS

The outdoor temperature trend indicators will update every 30
minutes or less. These trends represent temperature changes over
the past three hours.

Temperature rising more than 1°C/ 2°F in the past three

hours

Temperature has not changed more than 1°C/ 2°F in the

past three hours.

Temperature falling more than 1°C/ 2°F in the past three

hours
The temperature trend indicators are shown next to the indoor

temperature and outdoor temperature readings.

POSITIONING THE TEMPERATURE TRANSMITTER

The remote temperature transmitter should be mounted vertically to
avoid damage. Place both units in the desired shaded locations, and
wait approximately 1-hour before permanently mounting the
transmitter to ensure that there is proper reception. The outdoor
temperature transmitter is water resistant, not waterproof and should
not be placed anywhere it will become submerged in water or
subject to standing water or snow.

WALL MOUNT

Choose a location for the transmitter that is within range of the
Wireless Thermometer and under an overhang for accuracy.

Option 1:

Install one mounting screw (not included) into a wall

leaving approximately ½ of an inch (12.7mm)
extended.

Place the transmitter onto the screw, using the

hanging hole on the backside.

Gently pull the transmitter down to lock the screw into

place.

Option 2:

Insert the mounting screw (not included) through the front of the

transmitter and into the wall.
Tighten the screw to snug (do not over tighten).
To achieve a true temperature reading, mount where direct

sunlight cannot reach the outdoor transmitter. Mount the outdoor

transmitter on a North-facing wall or in any well shaded area.

Under an eave or deck rail work well. 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. Place the transmitter at least 6 feet in the air to

improve signal transmission.
