GETTING STARTED

SETTING UP THE CLOCK

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

RESET

after each battery change.

SENSOR DATA TRANSMISSION

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

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

for each sensor.

4. Place the sensor near the main unit. Press RESET on

the sensor.

5. Simultaneously press CHANNEL and MEM on the main

unit to initiate signal sending between the sensor and
main unit.

6. Close the battery door and secure the screws.
7. Place the sensor in the desired location using the table

stand or wall mount.

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).

Data is sent from the sensor(s) every 40 seconds. The
sensor reception icon in the remote sensor area shows
the status.

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.

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. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).

The sensor collects the radio signals whenever it is within
1500 km (932 miles) of a signal.

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.

To enable and force a signal search:

Press and hold for 2 seconds.

To disable the signal reception:

Press and hold for 2 seconds.
