SETTING AMBIENT (IN) TEMPERATURE ALARM LIMITS
1. Select the Ambient Temperature Display Mode by pressing the IN/OUT button located on the back of
the unit until "IN" appears on the display.
2. Press MODE button until "LO" and "HI" appears.
3. To set the low temperature alarm limit (LO), press the LO ALM SET button to advance the display until
the desired low temperature is displayed.
4. To set the high temperature alarm limit (HI), press the HI ALM SET button to advance the display until
the desired high temperature is displayed.
ENABLE/DISABLE ALARMS
To enable the alarm to sound when the temperature being displayed is outside the alarm limits, press the 
button located on the back of the unit until "" appears on the display. Each successive press of the 
button will enable () or disable the alarm.
ALARM SOUNDING
With the alarm enabled (), the unit will sound an alarm when the temperature being displayed is outside
the alarm limits that have been set for that display mode (equal to or lower than the low alarm set point, or
equal to or greater than the high alarm set point). If the alarm is sounding based on the low alarm limit, "LO"
will flash on the display. If the alarm is sounding based on the high alarm limit, "HI" will flash on the display.
The unit will continue to alarm and flash the corresponding "LO" or "HI" until the temperature being displayed
is within the alarm limits. Once the temperature being displayed is within the alarm limits, the alarm will stop
sounding and the corresponding "LO" or "HI" will no longer flash.
To silence an alarm manually, press any button. When manually silenced, the corresponding "LO" or "HI" will
continue to flash on the display until the temperature is within the alarm limits. When enabled (), the alarm
will only sound if the temperature being displayed is outside the alarm limits that have been set for that
display mode (IN or OUT). Example: If the unit is displaying ambient temperature (IN) and the probe
temperature (OUT) is outside the probe temperature alarm limits, no alarm will sound.
