Programming the Alarm
By default, the high and low alarm settings are 8
o
C and 2
o
C respectively. To reset high alarm and low
alarm temperature settings, follow instructions below.
This is the high temperature limit. The current temperature is considered out-of-range if the probe
reads a temperature equal to or above the high temperature limit.
Press once to enter the high temperature alarm setting mode. HI-SET will display on the LCD
screen. Press ▲ or ▼ to increase or decrease the value. Then, press the HIGH ALARM button
to confirm. The LCD screen will return to the current temperature.
This is the low temperature limit. The current temperature is considered out-of-range if the probe
reads a temperature equal to or below the low temperature limit.
Press once to enter the low temperature alarm setting mode. LO-SET will display on the LCD
screen. Press ▲ or ▼ to increase or decrease the value. Then press the LOW ALARM button
to confirm. The LCD screen will return to the current temperature.
Eliminating the Alarm Indicators
When an alarm condition occurs LO-ALARM/HI-ALARM icons will appear on the display along with a

event still exists.
Press the and keys simultaneously to clear the LO-ALARM/HI-ALARM indicators. The
alarm will not clear if the alarm event still exists.
Using the Alarm
• Placement: Once the thermometer has been programmed, place the temperature sensor (in glycol
bottle) in the location to be monitored, such as inside the refrigerator or freezer. Attach the
thermometer to the door of the unit using its magnet.
• If the temperature measurement rises above or falls below the set temperature range, the alarm will
sound. To silence the alarm, press any key ONCE.
• The alarm/thermometer’s maximum and minimum readings reflect the highest and lowest
temperatures since the battery was inserted or since the RESET button was last pressed.
By default, ALARM feature is activated. To turn it OFF follow the instructions below:
Long press for 2 seconds to turn the alarm feature ON/OFF.
PLEASE NOTE! When the alarm feature is turned OFF, both the visual and audible alarms are
turned OFF and the user will NOT be notified of any high or low alarm violations.
When alarm is ON, the alarm icon will be displayed and the user can receive visual and
audible alarm notifications.
Set the high and low alarm temperature limits above and below the refrigerator/freezer operating
temperature to prevent false alarms. Refrigerators are designed to run between 2-8 °C (36-46 °F)
while freezers run below -15 °C (5 °F).
