GETTING STARTED

 BATTERIES

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

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

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). 

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.

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.
