Placement
Sensor #1 should be placed in the REFRIGERATOR. Sensor #2 should be placed in
the FREEZER. (Note: both sensors have the capability of being placed in either the
refrigerator or freezer.) Each sensor is equipped with a spring-action clip with rubber
grips to securely hold the remote unit to the edge of a glass or wire shelf.
Each sensor also includes a detachable suction cup that may be used to secure the #1
remote sensor to the interior surface of the refrigerator. Suction cups do not adhere
to freezing surfaces very well, a remote unit kept in a freezing temperature should be
secured using the integrated spring-clip.
#2 Remote Sensor
shown here mounted to the
interior wire shelf of the freezer
using the integrated spring-clip.
#1 Remote Sensor
shown here mounted to
the interior surface of the
refrigerator using the included
suction cup.
The main unit may be mounted directly
to the refrigerator surface utilizing the
magnetic back of the unit. The main
unit may also be placed on a table or
other flat surface using the integrated
fold-out stand on the back of the unit.

Main Unit
Each sensors’ temperature is represented on the main unit in three ways:
The LARGEST numbers displayed are the CURRENT temperature of each sensor.
The two SMALLER numbers to the right in each sensors’ display window are the MINIMUM
and MAXIMUM recorded temperatures.
The recorded MIN/MAX numbers can be cleared by pressing and releasing the “CLR” button.
You may also choose between Fahrenheit or Celsius temperature display by using the
“ºF/ºC Select” switch on the back of the main unit.
Low Battery Indicator
A low battery indicator icon is shown in the display window for each sensor. When the low
battery icon appears, replace the batteries in the sensor with fresh ones. Be sure to never
mix old and new batteries, and never mix battery types such as alkaline and lithium together.
Temperature measurement range:
SENSORS: -40ºF to 158ºF
NOTE: If the sensors are measuring temperatures above the measurable temperature
range the main unit will display “-H-”. If the sensor are measuring temperatures below
the measurable temperature range, the main unit will display “-L-”.
Temperature Alarms
The main unit is equipped with an audible temperature alarm for each sensor.
TO SET ALARM
PRESS the alarm button ( or ) for the corresponding sensor to turn the alarm function
ON or OFF.
The “ ” icon on the main display will appear if the alarm function is ON. If the alarm
icon is NOT displayed, the alarm WILL NOT SOUND.
The ALARM will sound if the temperature of the sensor falls below or rises above the preset
MIN/MAX for more than 15 minutes. This is to prevent “false alarms” from sounding because
the door was opened to load or unload items from a refrigerator or freezer
The alarms are preset with the FDA’s MIN/MAX temperatures for a freezer (sensor #2) and
refrigerator (sensor #1). THE DEFAULT FDA PRESET ALARM TEMPERATURES ARE:
Sensor #1 (REFRIGERATOR): MIN is 33ºF / MAX is 40ºF.
Sensor #2 (FREEZER): MIN is -22ºF / MAX is 0ºF
ALARM
For the sensor that is placed in the freezer (#2), it is recommended that 2 “AA” lithium
batteries be installed instead of alkaline batteries. Lithium batteries function at lower
temperatures better than alkaline batteries.
4 • TROUBLESHOOTING
The MAIN UNIT will display “--” when batteries are installed until it acquires the wireless
signal from the sensors. If the main unit still displays “--” or “-E-” the sensors’ batteries
may be dead or the main unit and sensors cannot synchronize wireless signals. Remove all
batteries and follow the setup instructions again, then move the MAIN UNIT to a different
location.

Basic Setup is Now Complete
The sensors will soon send a signal to the main unit and the 3 units will be synchronized. It
may take a few minutes for synchronization to be complete. If any of the units appear to be
functioning improperly, refer to the troubleshooting section in this manual.

Temperature Alarms - Programming Customized Presets
TO CUSTOMIZE THE PRESET ALARM TEMPERATURES
PRESS and hold the desired alarm button ( or ) to view alarm setting, then release.
Set the MAX temperature by using the “+” or “-” buttons.
PRESS the alarm button again to confirm your setting , you will hear a beep.
Set the MIN temperature by using the “+” or “-” buttons.
PRESS the alarm button again to confirm your setting and exit, you will hear a beep.
Repeat this process to set the MIN/MAX alarm temperatures for the other remote sensor.
