compartment.
4. Place the sensor near the main unit. Press
RESET
on the
sensor. Then, press and hold
MEM
and
CHANNEL
on the
main unit 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 "Data Transmission" section for
more information.)
SET UP SENSOR
1. Open the remote sensor battery compartment with a
small Phillips screwdriver.
2. Insert the batteries, matching the polarity (+ and -) as
shown in the battery compartment.
5. Close the remote sensor battery compartment.
6. Secure the sensor in the desired location using the wall
mount or table stand.
For best results:
• Insert the batteries and select the channel before you
mount the sensor.
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 98 feet (30 meters) 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.
Standard Alkaline batteries contain significant amounts of
water. Because of this they will freeze in low temperatures of
approximately 10
°
F (-12
°
C). Disposable Lithium batteries
have a much lower threshold for temperature with an estimated
freezing range of below -40
°
F (-40
°
C).
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). The
Liquid Crystal Display in outdoor thermometers will remain
operational to -20
°
F (-7
°
C) with adequate power.
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
show the status.

SEARCH FOR SENSOR
To search for a sensor, press and hold
MEM
and
CHANNEL
(on the main unit) for 2 seconds.
To force a manual search for clock signals, press and hold
for 2 seconds. If no signal is found, check the batteries.
TIME ZONES
When the main unit receives an atomic clock signal for the
first time, or when you force a manual search for the atomic
clock reception, the time will automatically be set to Pacific
time (PA). To change to another time zone (MO - Mountain,
CE - Central or EA - Eastern) simply:
1. Press and hold
MODE
for 2 seconds.
2. Press or to change the setting.
3. Press
to confirm and exit setting mode.
TURN ATOMIC CLOCK ON / OFF
Perform this step if you cannot receive atomic clock signals.
Press and hold for 2 seconds. Then, manually set the clock
following the “Set Clock” instructions (below).
The signal icon indicates that the clock feature is ON. No
icon means that it is OFF.
SET CLOCK / CALENDAR
You only need to do this if you have disabled the atomic clock
feature (for example, if you are too far from or cannot receive
a signal).
1. Press and hold
MODE
for 2 seconds. The Clock Area will
blink.
2. Select the time zone, hour, minute, year, month, day, and
day of the week language. Press or to change the
setting.
3. Press
MODE
to confirm.
The time zone options are PA (Pacific), MO (Mountain), CE
(Central) and EA (Eastern).
The language options are (E) English, (F) French, (D) German,
(I) Italian, and (S) Spanish.

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.
CLOCK
The clock automatically synchronizes the current time and
date when it is brought within range of the WWVB-60 atomic
clock signal generated from Fort Collins, Colorado. For more
information, please visit: www.boulder.nist.gov/timefreq/sta-
tions/>radioclocks.htm
NOTE
The 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 set up the unit, and whenever you press
RESET
. If the RF
signal is weak, it can take up to 24 hours to get a valid RF
signal reception. Once complete, the reception icon will stop
blinking. The icon is shown in the Clock Area.
ACTIVATE ALARM
Press to activate or deactivate the alarm. shows in the
Clock / Alarm Area when the alarm is activated.
SILENCE ALARM
When the alarm time is reached, the crescendo alarm will
sound for 2 minutes. To silence the alarm:
• Press
SNOOZE
to silence it for 8 minutes.
OR
• Press any key except
SNOOZE
to mute the alarm and
activate it again after 24 hours.
If no button is pressed, the alarm will automatically silence
after 2 minutes. It will then sound again after 8 minutes.
WEATHER FORECAST
