Your Model RF-02 Digital Refrigerator/Freezer Thermometer is the
newest and most innovative electronic thermometer that accurately
indicates the instant temperature of your refrigerator and freezer. It also
computes and displays the weekly average temperatures for both. You
can set weekly average temperature maximums. This is monitored and
indicated by four small lights. Two green lights if the average weekly
temperature for both your refrigerator and freezer are within the range
of set maximum temperature +/- 3ºF and red if they are out of the
range.
• Red or Green indicator lights at the bottom of the LCD advise
average weekly Refrigerator temperature status.
• Green lights if the average weekly temperatures are within the
maximum temperature +/3ºF you set. Indicating the
freezer/refrigerator is keeping food cold enough.
• Red lights if the average weekly temperatures are out of the
maximum temperature +/- 3ºF you set. Indicating the
freezer/refrigerator is either not keeping food cold enough or too
cold.

hold the MODE button for 3 seconds.
• The unit has a battery saving light sensor that turns on the red or
green lights only when the refrigerator door is open.
• The unit has internal temperature sensor for the refrigerator and a 6 ft

BATTERY REPLACEMENT
The unit is powered by two replaceable 1.5 volt AAA extra heavy duty
batteries which should last half year assuming the refrigerator door is
opened an average of 20 times per day for 7 seconds each time. To
replace batteries lift off the unit from the mounting bracket. Remove
the battery cover on the rear of the unit and pull out used batteries
noting polarity. Insert two new extra heavy duty AAA batteries.
HELPFUL HINTS
If the LCD only displays –22 –22 reset the circuit by removing the
batteries, waiting a few minutes and then replacing.
The unit will take 30 minutes, after you put it in your refrigerator, to
accurately measure the temperature.
Do not pull on the freezer probe wire.
Most authorities recommend your freezer be at 0ºF and your
refrigerator be between 37ºF - 40ºF.
• Remove the mounting bracket from the unit. Remove the non-stick
tape paper from the adhesive tape and stick the mounting bracket on
the left wall of the refrigerator compartment near the top and front so
it can be easily viewed when the refrigerator door is opened.
• Attach the unit on the mounting bracket and place the freezer probe
wire in the freezer. Be careful not to pinch the wire in door hinge or
any place else with a sharp edge. The wire should exit the refrigerator
so it lies flat against the body of the refrigerator. There are two
mounting clips with adhesive tape to help position the freezer wire
and probe.
