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 (+ / -).
Press RESET 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 signicant 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.
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.
CLOCK
CLOCK RECEPTION
This product is designed to synchronize its date and time
automatically once it is within range of :
• DCF77 generated from Frankfurt, Germany for
Central Europe.
• MSF60 generated from Rugby, England.
The clock collects the radio signals whenever it is within
1500 km (932 miles) of a signal.
NOTE Slide the EU / UK switch to appropriate position
for your location. Repeat each time you reset the unit.
NOTE Initial reception takes 2-10 minutes for rst 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.

2. Press and to change the settings.
3. Press MODE to conrm.
4. The setting sequence is: time zone offset, 12/24 hour
format, hour, minute, year, month, date, and display
language.
NOTE The time zone offset can be used to set the
clock up to + / - 9 hours from the received clock signal
time. If you have disabled the clock signal reception (i.e.
manually setting the clock), do not set a value for time
zone offset.
NOTE The language options are English (E), German
(D), French (F), Italian (I), and Spanish (S).
To switch the clock display:
Press MODE to toggle between:
• Clock with day
• Clock with seconds
ALARM
To set the alarm:
1. Press and hold ALARM for 2 seconds.

2. Press ALARM again to turn alarm ON / OFF.
To silence the alarm:
• Press SNOOZE to silence it for 8 minutes.
OR
• Press any key except SNOOZE to turn the alarm off
and activate it again after 24 hours.
TEMPERATURE AND HUMIDITY
To toggle temperature unit:
Press °C / °F.
To view outdoor sensors temperature readings:
Press CHANNEL.
To auto-scan between sensors:
Press and hold CHANNEL for 2 seconds. Each sensor’s
data is displayed for 3 seconds.
To end auto-scan:
Press CHANNEL or MEM.
To toggle between current, minimum and maximum
records for the selected sensor:
Press MEM repeatedly.
To clear the records:
Press and hold MEM for 2 seconds.

TEMPERATURE AND HUMIDITY TREND
The temperature and humidity trend icons are based
on recent readings.
RISING STEADY FALLING
ICE WARNING
If the channel 1 sensor falls between 3°C to –2°C (37°F
to 28°F), ashes to warn you that the temperature is
approaching freezing.
NOTE The warning will automatically stop if the
temperature goes outside the ice-warning range.

An alarm can be set to sound if sensor set to channel
1 records above or below a temperature / humidity of
your choice.
To set alarm ON/OFF:
1. Press and hold TEMP / HUMIDITY HI / LO .
2. Use and to select high / low temperature /
humidity alarm. Press TEMP / HUMIDITY HI / LO
to conrm.
3. Press / to set alarm ON / OFF and press TEMP
/ HUMIDITY HI / LO to conrm.
