SETTING THE DATE
1. Press and release the TIME/DATE button until
 
the display shows the date (indicated by Month,
Date, and Year on the display).
2. Press and hold the TIME/DATE button for three
 
(3) seconds (the Year digits will fl ash). Press
the MODE button to advance the year.
3. With the desired year on the display, press the 
 
TIME/DATE button (the Month digits will fl ash).
Press the MODE button to advance the month.
4. With the desired month on the display, press
 
the TIME/DATE button (the Date digits will
fl ash). Press the MODE button to advance
the date.
5. With the desired date on the display, press the
 
TIME/DATE button. The date will be saved.
Note:
While in the setting mode, if no button is pressed
for ten (10) seconds, the unit automatically exits from the 
setting mode.
VIEWING THE DATE
To view the date, press the TIME/DATE button, 
the current date will appear on the display. After 
approximately ten (10) seconds the display will 
automatically return to the time-of-day display. 
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit 
or Celsius, slide the °C/°F button, located on the 
back of the unit, to the desired position.
DISPLAYING SENSOR 1 OR SENSOR 2
Press the S1/S2 button to display the desired 
temperature sensor reading. The corresponding 
S1 or S2 indicator will appear at the top left corner 
of the display. When switching between sensors, 
the display will show “--.-” for approximately 2 
seconds. 
MINIMUM AND MAXIMUM MEMORY
There are four points that are automatically 
recorded into memory:
 • Minimum (MIN) Sensor 1 (S1) Temperature
 Achieved with time-of-day and date achieved
 • Maximum (MAX) Sensor 1 (S1) Temperature
 Achieved with time-of-day and date achieved
 • Minimum (MIN) Sensor 2 (S2) Temperature
 Achieved with time-of-day and date achieved
 • Maximum (MAX) Sensor 2 (S2) Temperature
 Achieved with time-of-day and date achieved
Minimum and maximum temperature memories 
are NOT programmable. The minimum temperature 
recorded into memory is the minimum temperature 
achieved since the last time the memory was 
cleared. The maximum temperature recorded into 
memory is the maximum temperature achieved 
since the last time the memory was cleared. The 
minimum and maximum temperature memories are 
maintained over the period since the memory was 
cleared. 
Minimum and maximum memories are recorded for 
both sensors regardless of the display mode.
VIEWING THE MINIMUM/MAXIMUM MEMORIES
1. Press the S1/S2 button to display the desired
 
temperature sensor.
2. Press the MODE button, the minimum
 
temperature achieved by that sensor along with
the time-of-day the temperature was achieved
will appear on the display (indicated by MIN
on the display).
3. To toggle the display between the time-of-day/
 
date achieved, press the TIME/DATE button.
4. Press the MODE button a second time, the
 
maximum temperature achieved by that sensor
along with the time-of-day the temperature was
achieved will appear on the display (indicated
by MAX on the display).
5. To toggle the display between the time-of-day/
 
date achieved, press the TIME/DATE button.
Note:
If no button is pressed for ten (10) seconds, the
unit automatically returns to the current temperature/
time-of-day display mode.
6. To exit from the memory display mode, press
 
and release the MODE button until MIN,
MAX, LO, HI no longer appears on the display,
or simply do not press any button for ten (10)
seconds.
SPECIFICATIONS
Range: 
-58.0 to 158.0 °F / -50.0 to 70.0 °C
Resolution:
0.1°
Update Rate: 10 seconds
Battery: 
2 each AAA (1.5V)
Probe Supplied:
Model 4306-- 
Supplied with dual bottle sensors
and cables. Designed for use in refrigerators 
and freezers, the bottle sensors are fi lled with a 
patented nontoxic glycol solution that is GRAS 
(Generally Recognized As Safe) by the FDA (Food 
and Drug Administration) eliminating concerns 
about incidental contact with food or drinking water. 
The solution fi lled bottle simulates the temperature 
of other stored liquids. Velcro
®
and a magnetic
strips are provided to mount the bottle to the inside 
of a refrigerator/freezer. The micro-thin probe cable 
permits refrigerator/freezer doors to close on it. 
(Do not immerse bottle sensors in liquid).
Model 4307--
Supplied with dual standard probe
sensors with cables. Designed for use in air and 
liquids, the sensor and cable may be completely 
immersed. Probe sensors may be mounted using 
the supplied suction cup holders.
SETTING THE TIME-OF-DAY
1. Press and release the TIME/DATE button until
 
the display shows the time-of-day (indicated by
HR, MIN and SEC on the display).
2. Press and hold the TIME/DATE button for three
 
(3) seconds (the hours digits will fl ash). Press
the MODE button to advance the hours.
3. With the desired hours on the display, press 
 
the TIME/DATE button (the minutes digits will
fl ash). Press the MODE button to advance
the minutes.
4. With the desired minutes on the display, press
 
the TIME/DATE button (the seconds digits will
fl ash). Press the MODE button to advance
the seconds.
5. With the desired seconds on the display, press
 
the TIME/DATE button. The time-of-day will
be saved.
Note:
While in the setting mode, if no button is pressed
for ten (10) seconds, the unit automatically exits from the 
setting mode.
CLEARING THE MINIMUM/MAXIMUM MEMORIES
When clearing the min/max memory, all four 
memories (S1 Min/Max and S2 Min/Max) are 
cleared simultaneously, regardless of which 
sensor or memory value is being displayed.
1. Press the MODE button to enter the memory
 
display mode (indicated by MIN or MAX
appearing on the display).
2. Press the CLEAR button to clear the 
 
temperature memories. The display will show
all dashes and will then display the current
probe temperature and time-of-day.
ALARMS
Both temperature sensor (S1/S2) alarm limits may 
be set in 1° increments. Sensor 1 and Sensor 2 
alarm limits are set independent of each other.
With the alarm enabled (
֠
), the unit will sound an
alarm when the temperature measured is outside 
the alarm limits that have been set (equal to or 
lower than the low alarm set point, or equal to or 
greater than the high alarm set point).
The alarm will sound regardless of which sensor 
is being displayed. Example: If Sensor 1 is 
being displayed, but Sensor 2 reaches an alarm 
condition, the alarm will sound and the display 
will automatically change to display the Sensor 2 
temperature.
SETTING THE TEMPERATURE ALARM LIMITS
1. Press the S1/S2 button to display the desired
 
temperature sensor.
2. Press the MODE button 3 times (LO will appear
 
on the display).
3. Press and hold the SET button for three (3)
 
seconds. The low alarm set point will fl ash
on the display.
4. To set the low temperature alarm limit (LO),
 
press the MODE button to advance the display
until the desired low temperature is displayed.
Press and hold the MODE button to rapidly
advance the display.
5. With the desired low temperature alarm limit 
 
on the display, press the SET button (the high
alarm limit (HI) will fl ash on the display).
6. To set the high temperature alarm limit (HI),
 
press the MODE button to advance the display
until the desired high temperature is displayed.
Press and hold the MODE button to rapidly
advance the display.
