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

#2 interior wire shelf of the freezer using the integrated spring-clip.

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.

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.

3 • USE

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.

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 “ALARM ” 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

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.

	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.

3 • OPERATION

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-”.

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.
