GETTING STARTED

BATTERIES

Insert batteries before first use, matching the polarity (+ and
-). Press

RESET

after each battery change.

indicates main unit batteries are low.

NOTE

Do not use rechargeable batteries. We recommend

that you use alkaline batteries with this product for longer
usage and lithium batteries in temperatures below freezing.

REMOTE SENSOR

The sensor collects temperature readings approx. every 40
seconds and sends them to the main unit. The main unit can
collect data from up to 3 sensors.

To set up the sensor:

1. Slide open the battery door.
2. Insert the batteries, matching the polarity (+ / -). Reset

the sensor after each battery change.

3. Select a channel. Make sure you use a different channel

for each sensor.

4. Close the battery compartment.
5. Secure the sensor in the desired location using the wall

mount or table stand.

For best results:

• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 m (100 ft) 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.

The transmission range may vary depending on many factors.
You may need to experiment with various locations to get
the best results.

Standard Alkaline batteries contain significant amounts of
water. Because of this they will freeze in low temperatures
of approximately -12°C (10°F). Disposable Lithium batteries
have a much lower threshold for temperature with an
estimated freezing range of below -30°C (-22°F).

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).

SENSOR DATA TRANSMISSION

The sensor reception icon in the temperature and humidity
area shows the status.

ICON DESCRIPTION

Main unit is searching for the

sensor(s)

A channel has been found and

sensor signal is being received
and “- - . -“ The sensor cannot be found.
(Temperature Search for the sensor or
and Humidity Area) check batteries

To search for a sensor:

Simultaneously, press and hold

MEM

and

CHANNEL

for

2 seconds.

NOTE

If the sensor is still not found, check the batteries,

obstructions, and remote unit location.

CLOCK

CLOCK RECEPTION

This product is designed to synchronize its date and time
automatically once it is within range of the WWVB-60
signal from the atomic clock in Fort Collins, Colorado.

The clock collects the radio signals whenever it is within 3219
km (2000 miles) of a signal.

NOTE

Press

ZONE

to select the US time zone: Pacific (P),

Eastern (E), Central (C) or Mountain (M).

NOTE

Initial reception takes 2-10 minutes for first set up or

when

RESET

is pressed. Once complete, the reception icon

will stop blinking. If the signal is weak, it can take up to 24
hours to get a valid signal.

RECEPTION SIGNAL

Clock signal reception indicator:

STRONG SIGNAL WEAK SIGNAL NO SIGNAL

To enable and force a signal search:

Press and hold for 2 seconds.

To disable the signal reception:

Press and hold for 2 seconds.

SET CLOCK

If the clock signal reception is enabled and a signal is being
received the clock does not need to be manually set.

To manually set the clock:

1. Press and hold

MODE

for 2 seconds.

2. Press and to change the settings.
3. Press

MODE

to confirm.

4. The setting sequence is: 12/24 hour format, hour, minute,

year, date / month format, month, date, and display
language.
