GETTING STARTED

BATTERIES

Batteries are not supplied with this product. You will need
to purchase 2 x UM-3 (AA) 1.5V alkaline batteries for
the main unit, and 2 x UM-4 (AAA) 1.5V alkaline batteries
for the remote sensor.

Insert batteries before first use, matching the polarity as
shown in the battery compartment. For best results,
install batteries in the remote sensor before the main
unit. Press RESET after each battery change.

Do not use rechargeable batteries.

NOTE

CHANGE SETTINGS

1. Press and hold MODE for 2 seconds to enter setting
mode.

2. Press UP or DOWN to change settings.

3. Press MODE to confirm.

TABLE STAND OR WALL MOUNT

Insert the stand on the back of the product, or mount it
on a wall with a nail.

REMOTE SENSOR (THGR122NX)

This product is shipped with a THGR122NX Thermo/
Hygro Sensor that collects Temperature and Humidity
data. Data can be collected from up to 3 sensors.
Additional sensors sold separately.

SETUP SENSOR

Open the remote sensor battery compartment with a
small Phillips screwdriver.

1. Insert the batteries, matching the polarity as shown
in the battery compartment.

2. Set the channel. The switch is located in the battery
compartment.

SWITCH OPTION

Channel

Channel 1 - 3. If you are using
more than one sensor, select a
different channel for each sensor.

3. Place the sensor near the main unit. Press RESET
on the sensor to initiate signal sending between the
sensor and the main unit. The reception icon on
the main unit will blink for approximately 3 minutes
while it is searching for the sensor. (Refer to the
Sensor Data Transmission section for more
information.)

4. Close the remote sensor battery compartment.

5. Secure the sensor in the desired location using the
wall mount or table stand.

For best results:

• Insert the batteries and select the channel and
temperature unit before you mount the sensor.

• Place the sensor out of direct sunlight and
moisture.

• Do not place the sensor more than 30 meters
(98 feet) 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.

You may need to experiment with various locations to
get the best results.

DATA TRANSMISSION

Data is sent from the sensor(s) every 40 seconds.
The reception icon shown in the Temperature and
Humidity Areas shows the status.

SEARCH FOR SENSOR

To search for a sensor, press and hold MEM and
CHANNEL for 2 seconds.

If the sensor is still not found, check the

NOTE

batteries, obstructions, and remote unit location.

Signals from household devices such as

NOTE

doorbells, electronic garage doors, and home security
systems may cause temporary reception failure. This is
normal and does not affect general product performance.
The reception will resume once the interference ends.

DESCRIPTION
Main unit is searching for

sensors.

At least 1 channel has
been found.

Channel 1 is selected (number
will change depending on the
sensor you select)

The selected sensor cannot
be found. Search for the
sensor or check batteries.

CLOCK

This product shows the current time, time zone, and day
of week in English, Spanish, or French. The time is
automatically updated by the US Atomic Clock in
Boulder, Colorado unless you disable this feature.
Signals are collected by the main unit when it is within
1500 km (932 miles) of a signal.

Initial reception takes 2 - 10 minutes, and is initiated
when you first setup the unit, and whenever you press
RESET. Once complete, the reception icon will stop
blinking. The icon is shown in the Clock Area.

To force a manual search for Atomic Clock signals, press
and hold UP for 2 seconds. If no signal is found, check
the batteries.
