cover. The unit will beep and all segments of the LCD will be activated.
Programming the Alarms:
The thermometer displays the internal temperature of the unit being monitored, as
well as the maximum and minimum temperatures reached. The maximum and
minimum readings reflect the highest and lowest temperatures since the battery was
inserted or since the MODE/RESET key was last pressed. If the temperature rises
above or falls below the set temperature range, the alarm will sound. By default, the
high alarm temperature setting is 8°C (46.4°F) and the low alarm temperature setting
is 2°C (35.6°F). To reset these limits, follow these instructions:
High Alarm Temperature Setting: Press the HI/LO key ONCE, then press
MODE/RESET to enter the High Alarm temperature setting mode. Use the Up and
Down arrows to adjust the temperature accordingly. Press MODE/RESET once
again to confirm the setting.
Low Alarm Temperature Setting: Press the HI/LO key TWICE, then press
MODE/RESET to enter the Low Alarm temperature setting mode. Use the Up and
Down arrows to adjust the temperature accordingly. Press MODE/RESET ONCE to
confirm the setting.
By default, the low and high alarms should be audible. To turn alarms on/off:
Audible High Alarm Setting: To make sure the high alarm is audible, press HI/LO key
ONCE (to activate HI-SET on the screen). Then press the ALERT ON/OFF key
ONCE to activate the HIGH-ALARM beeping sound. Press again to deactivate.
Audible Low Alarm Setting: To make sure that the low temperature alarm is audible,
press the HI/LO key TWICE to activate LOW-SET on the screen. Then press the
ALERT ON/OFF key ONCE to activate the LOW-ALARM beeping sound. Press
again to deactivate.
NOTE: Set high and low alarm temperature limits above and below the refrigerator/
freezer operating temperature to prevent false alarms. For operating
temperature ranges, see Temperature Parameters on page 9.
NOTE: For an activated high alarm and low alarm buzzer, the display should
indicate HI-ALARM and LO-ALARM (see illustration on previous page).
More details about the features and usage of the Thermometer/Alarm can be
found in the User Manual accompanying the unit.
